I do not recommend Montague Hills Dentistry. Had a dentist I have seen for 8 years and was very satisfied. Was told I had good dental hygiene, few problems. Kaiser offers dental via Delta Care USA as part of my package plan. Saw my regular dentist for cleaning in 2025, no issues. Waited 5 months and decided to try the Kaiser plan dentist. Was assigned to this office. They had no openings for three months, but took the appointment anyway. They did numerous x-rays, more than I ever had experienced. Felt like they were trying to find something wrong with me. The dentist comes in looks in my mouth for about 8 seconds and then says I need deep cleaning and a cap that never gave me any problems removed and redone. He said a gap between that tooth and another would cause me to eventually cause a root canal. I did not agree. I knew I did not need deep cleaning or a cap removed and redone. I asked to just have my teeth cleaned. He refused to clean my teeth unless I agreed to deep cleaning and a new cap. I got up off the chair and left. Set up an appointment with my old dentist. My regular dentist cleaned my teeth, x-rayed the tooth that so called needed a new cap and found no problems. No deep cleaning needed. Obviously to me he was trying to drum up extra income for himself. Then weeks later his office staff calls to ask when would I like to have my cap redone. Unbelievable! I am reporting him to Kaiser Delta Care USA. Beware! read more

I had a filling that fell off on Monday night. I called Tuesday morning to see if I can get an appointment. The soonest available was Thursday. I had my original appointment booked at 6:20. Asked if I can come in earlier. they booked it at 3:40 then called again to see if I can come in at five because at 3:40 appointment never got booked. I got there at 4:50 was not seen till 5:20 and stated that yes I would need to get a filling done and that I would have to come back. Then the doctor asked if I could wait today if his last two patients didn't show up, they would be seeing me. last two patients never came doctor left, and I was still waiting in the lobby. read more

This dental office is in insurance network. However, they use items not covered by insurance in the treatment. For example, D4265 (Biologic materials, $105) is commonly used in extraction. Insurance covers 80% so that you only need to pay $21. However, this office uses A10065 (Colaplug , $250) instead of D4265 (Biologic materials). Insurance doesn't cover A10065! You have to pay out of your pocket. The similar item is (0006) Zirfit Crown. The insurance doesn't cover it. You have to pay yourself. Why make patients' life so hard? read more

Love Dr.Celis! Have been with him for years. Dr and all staff is extremely kind and caring.

I chose this Dentist due to the reviews on Yelp. My issue is the lack of communication, shady billing, and violation of my HIPAA rights. During my visit, the dentist told me I had cavities behind my braces (brackets) and I needed to take my brackets off prior to getting them treated. I made an appt with my ortho but I forgot the paper with the listings on them. I called and the receptionist to inquire if she could fax them. She was very rude and said they are on my molars. As a result, my ortho said they wouldn't have to take my brackets off. (I could have started treatment a while back if I had known this information). I've only had 1 cavity in my life and after coming here I was told I had 6 more. When my ortho looked at my mouth he said he couldn't see any and recommended I get a second opinion. 2) My husband went here too and was told he needed over 500$ worth of cleanings? What? 3) I asked for a copy of my daughter's chart because they billed a "debridement" but NO ONE communicated that she had a wound or infection that needed to be cleaned. Additionally, They refused to give me her chart after I asked. This is in violation of my rights under HIPAA. The lack of communication, shady billing practices, and HIPAA violations are a no for me. Getting second opinions and changing dentists, ASAP. read more

Montague Hills Dentistry - General Dentistry Near Me - Milpitas, California

The office is very clean and friendly staff. The reason I gave MHD 2 stars because I had a very bad experience when I came in for my teeth cleaning. My appointment was 10:30 and waited for 35 min 'til I got called In. It took exactly 5 minutes to clean my teeth by the dental assistant. While she used the cleaning tools to scrape my teeth and water was plashing and dripping all over my face and neck. Of course she's not a dental hygienist or Dentist to perform the procedure that why she did a horrible job. My biggest mistake when selected this dental office in the first place. Be aware & do not be fooled by the great reviews. My experience speak louder than words. I do not recommend. read more

Have been coming here for about 4 years, these folks are great and the dentist explains everything and has great bed side manor with patients, four from my family use this dentist read more

It has taken me years to find a dentist that I felt comfortable with as I am just terrified of them. The first time I went into the office the front desk staff are amazing and very friendly including the hygienist. On my appointment consultation I spoke to the dentist Dr Celis and we went over some options on what we could do in my situation he took his time explaining everything and that's how I knew that he was the right dentist. One thing I'm terrified about is the injections to numb you I didn't even feel that at all he also had to extract two teeth I did not even feel when he did that . I am still going thru some treatments but my fear of dentist is a lot less now that I have found him. So if you FEAR going to a dentist visit Montague Dentistry you will not be disappointed. read more

Dr. Alejandro Celis and his team are a first class crew that created an AMAZING and SPOTLESS dental office, literally the best I have ever been to! I willingly travel from San Francisco for every appointment, its worth it! Unlike others, Dr. Celis and his team will show you your x-rays and diagrams and detail exactly what his plan is and why for your personal care. He explained procedures and processes in an easy to understand manner that had me feeling completely relaxed and confident in his work. He and his team truly take their time to create a completely pain free process, literally and metaphorically, from start to end. Under his care, my overall dental health has vastly increased. I couldn't be happier with the results and solid dentistry work I received. If you're searching for the right dentist, you found it here! Thank you Dr. Alejandro and all of your wonderful staff! read more

The first thing they want to do is Extract your money from your wallet and then they do shoddy work. They cant do root canals so they swap it out to their other dentist friend. Crown replacements are done by the hygienist when I thought the actual dentist would do it. Avoid this place entirely. Biggest mistake I ever made was choosing them in the first place. read more

I have had some work done here and everytime i feel no pain I am the biggest chicken ever when it comes to my teeth the entire staff is so nice and friendly i feel so welcome when i visit i finally found a denist office who i can stay with !! There hours work with any schedule . Happy Patient :) read more

Superb service. I'm very thankful for this office because of their great, quality dental work. I recently got my wisdom teeth removed and am very pleased with the results and procedure. Really quick service and skilled professionals. They even sent me a digital copy of my mouth x-ray scan for my possession at my request! Haha great stuff doctors! read more

I have been a patient at this clinic for several years and I have always received a great service not only from both of Dr. Celis but also from their entire staff. I have had major treatments including 5 crowns, fillings, and cosmetics and I couldn't be happier with their work and the quality of the materials they use. Dr. Celis have replaced some of my old crowns which were not old at all but were just coming apart and since, my new crowns (which by now are 2-3 year old) are still in perfect condition and beautifully done. A plus, I am lucky not to be to nervous with injections but other dentists still made me hurt a little; with Dr. Celis, I barely felt the sting. Great doctors, I highly recommend them. read more

I came to this office looking for a 2nd opinion. Dr. Celis, was super friendly and helpful. He asked regarding my needs and wants besides just telling me what he thinks. Based on that we were able to come up with a plan that was perfect for my needs. Rocio was a great help, she efficiently provided billing information. Her customer service is excellent. She is really knowledgeable in the billing. Thank you Montague Hills, read more

Montague Hills Dentistry - My new implant! "Minimum invasive" - General Dentistry Near Me - Milpitas, California

My dentist that I had been seeing for 15+ years left my family and I (sisters, nieces, brother in law) stranded (he moved his practice to Vegas) and we were left scrambling to find another even better dentist. Luckily for us, we found Dr. Celis and Montague Hills Dentistry. He's gentle, he uses state of the art tools and equipment and he's very thorough. Not to mention he is great with children -- my youngest niece who's 5 to the other 2 who are 10 love going to see him. Make an appt today -- you won't regret it! read more

Nobody likes to go to the dentist and that is a well known fact, however Drs Celis made every visit a pleasant one. The staff was super friendly and professional. The office is clean as a whistle and parking is not an issue. I had to come back a couple of times as I had a small infection on my gums, which was treated in time and with no further consecuences. One of the things that caught my attention since the beginning was the fact that they use the latest technology, it may seem expensive but it's worth every penny. Nothing like having a good smile and Montague Hills made it happen! I'm looking forward to come back in a few months to get my teeth cleaning again. read more

Doctor Alejandro Celis is One of the Finest in Town. The Staff is Great and very Help full, the Dentistry is New And Clean, has the latest technology and equipment, the new of the Hills from the Chair is Cool. Nova, The Manager Explains very Clearly your Insurance Plan, and which items they cover and which they don't in their Consultation Room. My Wife goes to the same place with the Other Brother and had the same Experience as me, not to mention they are Open till 7pm, very convenient and Open on Saturdays too... Go and Check out their place...its an A+ read more

This is such an unprofessional and unethical office. I called since yesterday and continued today to get my husband in on an emergency appt because his lower partial needed an adjustment which was causing severe pain and discomfort . The front desk said she would need to check my insurance and also had to talk to the doctor. She called back and said manager Juanita wasn't in and that she handled this kind of emergency and also said doctor would not adjust his partial cause he didn't do that kind of procedures...What kind of doctor would refuse seeing a patient either because I had delta dental HmO or was too busy to see us...I was told to call back today at 10am to talk to Juanita but she called in sick and they were short handed....I do not recommend this office they don't care about taking care of their patients I wouldn't give then any ratings . read more

I've been going to Montague Hill Dentistry for the past couple years now, and I highly recommend this dentistry. When I was in elementary school, one of my front tooth got chipped and I had to get a porcelain crown. Throughout the years the metal underlying the crown's porcelain started to show a dark line which was very embarrassing! When I went to Dr. Celis, he recommended a new LAVA technology. for a crown Dr. Celis and his staff made the process painless and easy. My new LAVA crown looks so natural and even feels natural. I can definitely see and feel the difference between my old crown. People are always amazed when I tell them my front tooth is a crown. I've also had my silver fillings replaced to match the color of my teeth. Dr. Celis and his staff are knowledgeable and friendly. The office itself is very clean and modern. You also have a great view of the hills while you're getting work done. I highly recommend Dr. Celis and this dentistry for those who are looking for cosmetic work and just regular cleaning etc... read more

I recently moved to US and had issues with my jaw - I found this dentistry near my apartment. Dr Alejandro and all staff personel is great, it is easy to make an appointment, the clinic is very clean. It was very good experience and I will return there for my next appointment. read more

Since moving back to the bay area I have been out to find that one dental practice that I can really say is a keeper, and I think I may have found it. Ive been living across from the dental office for 5 years, and just discovered them this year. I was recommended by a friend. I had so much work that needed to be done, and I was really dreading the dentist. But they made me feel super comfortable. Dr. Celis and staff truly are one of a kind. All so very kind, funny, professional, and light hearted that it made you forget that you were sitting in the dentist's chair. O!! AND if you dont like heavy handed dentist...I recommend DR CELIS 100%. Ive had dentists before who would put their entire upper body weight on my face. I hate shots and I dont know how he does it, but you literally cannot feel the needle. WINNER!! Thanks Dr. Celis and team!!! read more

Recently stumbled across Montague Hills Dentistry through my list of providers on my insurance. I usually don't take the time to review places, but Dr. Celis & staff are nothing short of professional and friendly. I had my first crown done as well as cleaning on two separate occasions and left happy with the quality of work done. Thanks Dr. Celis & team! read more

First and foremost, I've been a patient of Dr. Oscar Celis for going on 7 years now and I have had the up most respect for this dentistry. I have a very busy lifestyle that prevents me from attending most of my appointments at the last minute, the staff has been very compromising and has never charged me last minute cancellation fees. Now who does that to a stranger that first came here 7 years ago and has been treated exactly the same up to this date, Montague Hills Dentistry is your answer... I have referred numerous patients and not once have I ever heard a negative comment. The entire staff is such team players that is all about our smile that matters to them and nothing else. Dr. Oscar Celis and Dr. Alejandro Celis have gone out of their way for me on several emergency, temporary crown fractures and have show up on their days off to place a temporary crown. Now who does that? Montague Hills Dentistry is your answer... I must say goodbye for now , but not forever, to end this review I have never been in such an up-to-date technology dentistry and have always been treated with much Love and Respect., because it's all about my smile that makes me come back!!! read more

Don't believe what these dentists tell you! It is hard to believe that these dentists want only cash not my insurance money. Most of the proposed procedures that are covered by my insurance; but they want only cash. Very unprofessional and unethical! read more

I had my dental appointment yesterday with Dr. Oscar Celis. I had an awesome experience with Dr. Celis as I alway do every six months for my check-ups. It was worth driving all the way from OC. The dental office is beautiful and impecable. The staff is very welcoming, attentive, courteous, and professional. I will see them again in six months. God bless them! read more

I definitely recommend Montague Hills Dentist, they are efficient, friendly and all team is so professional. I'm been with them for about 2 or 3 yrs now and I like it. read more

I recently selected Montague Hills Dentistry based on the reviews I saw here on Yelp. However, I am disappointed and extremely frustrated with the service I received from their staff. My new insurance listed my co-payments very clearly, but Montague Hills Dentistry insisted that their schedule of benefits listed that I had to pay over $150 more than my co-payment for the services I needed. I faxed them my schedule of benefits, which I had downloaded from my insurance's web site, and then Montague Hills decided to DROP my insurance plan...that seems sketchy to me... To make matters worse, Tracy, the manager/receptionist/etc., was incredibly rude. Her tone was harsh and she refused to let me speak to her supervisor, she claimed she was her own supervisor. They dropped my plan after they suggested my follow-up services, but would not give me my X-rays to take to a new dentisit, a dentist I had to find because they decided to drop my plan. They wanted to charge me yet again to give me a copy of my X-rays (my insurance representative said they are supposed to at least transfer the X-rays digitally to my new dentist at no cost). This business may look shiny and pretty in their online pictures, but they are more concerned with making money than customer satisfaction and service, and I for one do not want people like that taking care of my dental needs. And the service? My entire exam and cleaning took 15 minutes. Dr. Celis did both, and he did not floss my teeth. I sure do miss my old dentist, Dr. Dirocco in Berkeley, I wish he was covered on my current plan... read more

Okay services , the $50 extra charge to cancellation even if you call them 24 hours ahead . Worst condition to lock the customer :( I am never going there again :( read more

Dr. Celis is this wonderful dentist who is just blessed with the lightest hands on the planet! I've been coming here for 3 years now and it has always been a pleasant experience. I've had my 4 wisdom teeth extracted and yes, it was painful, but he did it quick. He's very meticulous with cleaning and is also really nice, making sure im doing fine and am comfortable. the dental assistants are also very helpful and knowledgeable. they are very much trained well in this facility. What i also like is that they call me for whatever's due. cleaning or follow up appointements. With my busy schedule...that's the last thing i would ever remember doing. The office itself is really clean. the equipments are all still covered in plastic and the atmosphere is so light and relaxing. even the bathroom is a complete zen. I'd definitely recommend this dentistry office to everyone who needs a good dentist in the area. read more

I feel extremely comfortable in this office. Doctor Alejandro Celis is wonderful and very accommodating. Overall, I've had a very positive experience. read more

This is my first visit with Dr. Oscar Celis to have my (broken) wisdom tooth extracted for the 1st time in my life (1st tooth) ever! I was nervous and uncertain but Dr Celis answered my questions and assured that there should be no pain at all. After 2 shots of local anesthesia, Dr. Celis worked fast, pulled it, stitched it with a collagen types of plug to fill the hole. The whole procedures, I felt NO PAIN, just pulling pressure. Waited 10 days, stiches out..NO PAIN. Good job and very honest and upfront about price and expectation. Good follow up too :) read more

I can't say enough about the two brothers who are the best dentists I've encountered. They immediately put me at ease and have a "home town" vibe that makes you feel like an old friend. They are very professional and use the latest techniques and state of the art equipment. I had regular visits (2-4 per month) over a year and a half period while using Invisalign. I will soon relocate to Southern California and wish I could take these guys with me. They will be a tough act to follow. read more

This dentist Oscar Celis office is very unprofessional. They cancel my appt 3 times already before I ever had a chance to go in. I have been waiting for over 3 months to get this appt. because they said they were busy and all booked up. So I waited forever this appt on Monday after waiting so many months. Someone from the dentist called me on a Friday to cancel my appt on Monday because she said there's an emergency. I think her name was Danielle. But not sure if it was Juanita. Anyways it was rescheduled for the next day which was Tuesday. I asked her if they will make sure they won't cancel that appt since I'm not allow to bring my baby and other kids to the appt. She told me no kids allow. So I said ok I'll make childcare arrangement. Then on Monday, I get a call from Juanita who said she was the office manager. I was out at that time. She told me that she has to cancel my appt again because of a emergency. I told her they already cancel and I had already made arrangements for my kids to be watched. She told me she can fit me next week at 11am. I said fine. I'll take that appt. A few hours later, I called to confirm my appt since I never got a text or email from Juanita. Danielle answered the phone a few hours later and told me my appt is moved back to 3.5 weeks later. I was so mad. I asked why they kept canceling my appt. I am well past my 8 months of wait. I'm not going to wait another month. I asked Danielle can they move up some other patients because it's not fair they keep canceling my appt. She told me because I'm a new patient, the other patients are a priority. I said but this is not fair. Please make an exception because it was not my fault they keep having emergency and canceling my appt. I, of course was mad. I raised my voice because I'm frustrated that I have to make my day and time available and make arrangements for my kids and they act like I'm not important just because I'm a new patient. And I'm pretty sure due the circumstances, they should be able to make an exception and squeeze me in. Then Juanita (office manager) took the phone from Danielle and told me because I'm being rude, she will cancel my appt which was set for almost another month back and I am no longer welcome as a patient. I called my insurance and file a report. They said what they did is wrong and I have a right to be frustrated because I didn't expect Juanita to just cancel my appt didn't care about why I'm so frustrated. I have a life too. I can't keep making appt and they keep saying they there's an emergency. Juanita shows no concern about how a person feels and how busy their lives can be. All she care about it taking patients who have better insurance. I understand that Danielle was just doing her job and maybe I should not raise my voice at her but I was upset. But for Juanita to take the phone and gave me no warnings or bother talking to me when I was just saying I'm sure they can make some accommodations to fit me in the schedule sooner, she just cancel my appt. She's heartless knowing I have kids and I'm very busy and yet my appts keep getting pushed back. I have never seen that many emergencies in any dentist place where they have to reschedule numerous times. read more

I would give negative star rating if i could. They are thieves. plain and simple. These people have no honesty, ethics or concious. I had almost same experience with other reviewer JF. I really doubt if any positive reviewe's are actual truth. My older dentist stopped taking DMO, so i had to switch. I had no complaints, no problem. I just went there for normal annual cleaning. doctor i saw told me i need deep cleaning, and other cavity fillings etc etc. it would cost me 700 dollars, and my insurance would not cover it. when i asked for my x-ray - it would cost 50 dollars. STAY CLEAR FROM THIS PEOPLE. I AM FILLING COMPLAINTS AGAINTS THEM WITH MY INSURANCE COMPANY AND STATE OF CALIFORNIA AS WELL AS ADA IF I CAN. read more

I am a patient of this practice for over 7 years. Never had any issues. Do all my dental work here. Staff is always friendly and honest. Never pushy! These days we have so many choices, right? Needless to say, we live 40 miles away from the office but we still keep this practice as our primary dental provider due to high quality and technologically excellent team. I saw some negative reviews posted here. When it comes to medical costs it is always the situation when people are quick to suspect doctor of over-charging. But come on, how can you post 1* review after being a patient for a few years? I would understand if someone walks out and not satisfied with the service after the first visit. This is the way we try and get our opinion. Anyway, my whole family is coming here few times a year and we always(!) have the same great experience! Here is the list of the procedures we received at this office: filings, extractions (incl. wisdom teeth), cleanings, bridge, crowns. Lastly, I would like to say that besides two brothers-owners, there is another doctor who is extremely professional and can be trusted. read more

I'm extremely satisfied with the results of the different types of treatment I had. The office staff is amazingly friendly and helpful. Dr Alejandro was very friendly and was always ready to answer all the questions I asked him so that I could have a better understanding of what was convenient for me to do. I highly appreciate his warm attitude and knowledge.Thank you very much Dr Alejandro for being patient with me. I can wear a wonderful smile now! read more

Dr. Celis has been my dentist for over 10 years and I have been completely satisfied! His staff are super friendly, courteous and professional. I've had to have a number of procedures and they have always gone smoothly, with little or no pain. Dr. Celis has always been informative during the procedure, explaining the process along the way. I have referred a number of my friends to Dr. Celis and they have also been very pleased. Thanks Dr. Celis! read more

The best dentists (Oscar & Alejandro) and their staffs (especially to Nova and Kenneth). My wife and I are so happy with their service. Highly recommended! read more
