Our experience with this office has been a nightmare, it revealed major operational and billing problems that patients deserve to be aware of. During a routine pre-appointment, the treatment estimate was revised several times because of repeated mistakes on their end -- incorrect fees, added procedures, and even an unexplained extra tooth listed on the paperwork. The only reason the final amount reflected the correct cost was because the errors were identified and compared against the insurance authorization. Sedation had been removed from the treatment plan in advance, and the procedure was already scheduled. After the billing issues were brought to their attention and paid, the office waited until the day of the procedure to cancel, stating the surgeon now "recommends sedation". This information was never mentioned previously, and the timing of it all how convenient. We also raised concerns about a separate payment that was misallocated internally after being made in person and staff said "we will take care of it". The account reflected a nonpayment even though the funds were applied incorrectly on their side. The Operations Manager was contacted for clarification, but no response has been provided. The pattern of errors and lack of accountability raises serious concerns about how this office manages patient care and billing. Families should be prepared to double-check all documentation and charges if they choose this location. Very unethical and unprofessional behavior lead the way this front office and billing team operate. read more

See all

If I could put 0 I would. DO EVERYTHING TO AVOID THIS PLACE. They are thieves! Aside from that they have the worst customer service. Horrible care and quality provided here. I made the worst mistake by trusting them with my dental care. read more

Do not come here.. place is a scam. If your UNION, don't go here as manager stated our insurance gives this office the hardest time and they don't like to deal with UNION PPO INSURANCE... This office has consistent problems with billing accuracy and basic accountability. Treatment estimates were revised multiple times in a single visit due to clear errors -- incorrect fees, added procedures, and paperwork that did not match the insurance authorization. Sedation was removed without issue, yet the office cancelled the procedure on the day of, citing new requirements that had never been mentioned. An in-person payment was also misapplied and incorrectly marked as unpaid, with no response from the Operations Manager after being contacted. Patients should expect to verify every charge and every document themselves or be overcharged for no other reason than greed. read more

This place is great. My kids see the kid dentist dr. Sidhu and dr. Leng is very gentle. Recommend them to all my neighbors and friends. The front desk is very kind and approachable. read more

Beware! They don't tell you upfront about the money you will need to pay. They love pulling teeth, rather than saving them. They should be taken to court. Flies in the exam room. Front door that you can't open. Stole probably $20 grand total from me. read more

This place needs to close. They have poor customer service. My son waited for 40mins for a hygienist, Ramia, then she cleaned his teeth for 10mins and was done. Service here gets worse every year. read more

Still working out quality and experience had a root canal and a two so call caps or crowns still having trouble with the tooth I didn't have problems with so keep you posted read more

I always have an amazing experience at Triangle Dental Group, it's so intimidating to see the dentist but the whole staff makes the process so comfortable and easy. I leave feeling confident about myself after my cleanings. I recommend my friends and family to get all their dental work done here because they are the best! read more

One word AMAZING the staff is so nice & helpful. & Dr.Harsheen sidhu is the best of the best I've taken my son to see other dentist before her, so he was already scared of the dentist but when we came to her everything changed. She takes special care of her patients. read more

Had been going here for years. Staff is nice and dentist does decent work but prices are high and found out that some work that was indicated to be needed was not when I went to another dentist seeking a second opinion. Check your insurance plan thoroughly before you go because there were questionable charges when I got my bill from my insurance provider. They had a charge for hygiene instructions when no such instructions were given during my visit and those costs weren't covered by my insurance. It came out of pocket, so I contacted triangle about that. Then I had a standard cleaning one time that I later found out should have been free and they charged me roughly $25. It's like they don't like you leaving their office without be charged in some way for something /them gouging you as much as they can. That did it for me. Found another dentist. read more

Poor patient service and care. Wanted to charge me an additional $100.00 for a follow-up appointment with a periodontal dentist. The follow-up appointment should have been part of the coverage from my periodontal surgery. I really needed the appointment for good dental follow up. I'm very unhappy with this office. I left and will seek follow-up care elsewhere. Follow up post: the periodontist called me 3 times very apologetic for the treatment I received and I will be seeing them at another office with no additional fees. This is an excellent result for my dental needs. read more

Been going here for years Very friendly staff Helpful Dentist does a great job Very reliable. read more

I am not a big fan of any type of dental work, I resist going as much as possible, unfortunately, my back molar cracked I needed to see a dentist, evidently my long period without seeing a dentist my check-up was not good news. I have a lot of work to do, today my two sessions of deep cleaning was completed, I appreciated Hygienist Ramia Alarkan, she made me comfortable and at ease while doing what needed to be done. The fact that I came back for the second session demonstrates that she did a good job. I hope Triangle will continue to change my perspective on dental work. read more

Triangle Dental is repulsively dishonest and disrespectful. I think this is the first negative review I've written about any business. Please don't trust them with your family's health. They lied three times to my face about not charging money for X-rays and then charged for them. Thankfully, I kept the document they printed out claiming they wouldn't charge me. I contacted the Better Business Bureau (BBB). After arguing disrespectfully, Triangle Dental finally "agreed" to submit insurance revisions and waive all fees. But a month later? They haven't done it. So now I'm having to reopen the BBB complaint and we're having to file grievances with two different dental insurance companies just to stop these slimeballs from stealing our money. Please look elsewhere if you enjoy being treated like a human being. read more

Run from this place terribly over priced how does a root canal cost 2,600.00 + and a implant 7,000.00 they are trippin I had 3 implants put in for 5,200.00 a year ago at Hyland dental in riverside great job to oh fyi they have 2 other sister dental offices in fontana just as expensive and try to up sale up with fearful / expensive scenario that could happen. they must work for commission again run and run fast..there are so many other dental that are way more reasonably priced. read more

I went here before the pandemic w Delta dental insurance. After taking X-rays etc. I was then told they don't accept this insurance. The front office personnel are not friendly. Why did I return? Simply bc I figured now that they like everyone else , has suffered some economic repercussions. BTW they now accept Delta dental insurance & bc they're located within walking distance of my neighborhood (Heritage). Again I recommend you take your business elsewhere bc this place these people, just don't get it. So sad. read more

INCOMPETENT BUSINESS!!! Vanessa has a very nasty attitude just like the other comment reported, All they want is money, they aren't concerned about effective treatments and will keep you in braces longer than needed so they can charge more. They hadn't scheduled my daughter for her braces adjustments in 7 months, I was still bringing her in for regular appts when I noticed adjustment weren't being made, when I called in to inquire as to why, they admitted to it being their mistake, once they rescheduled her again for Ortho appts, they then told me that I would have to pay an additional $650 to continue braces, when it was pointed out to them they said she wasn't wearing her rubber bands, BUT would not acknowledge the fact that the delayed appts, due to their incompetency had anything to do with it! TERRIBLE BUSINESS! read more

Love the staff here! They are all professional and help you right away! Thank you Blanca! She performed my dental cleaning and was amazing; will definitely recommend family and friends read more

Went for my daughters back in March and was told they would follow up with details about treatment and they never called back. I called them and no one answered for weeks. I finally got a hold of someone and they told me they would call me back to schedule another appointment instead of reviewing my previous appointment. I guess they don't want our service since they refuse to call anyone back. Don't waste your time coming here. read more

I have insurance, but was told by the staff my insurance doesn't cover hardly anything and it was the"worst" insurance she's seen. It's not like you walk around with your insurance coverage and codes. I got home and checked my coverage after being approved for 4900 on their credit card and the work "that they made fit" into exactly 4900. I feel that they've scammed me into believing my insurance coverage was what it was so that they could receive immediate payment by the credit card company rather than wait to be paid wait to be paid by the insurance company. My insurance covers a lot more than I was lead to believe. Per the codes they used , I (including the up charges for materials not covered) have been over charged by thousands. At this point , no claim for my insurance has been made by them. They're not responding to the insurance company and have made no attempt to contact us. We've filed a grievance with our insurance company days after the service (end of January). And since have been in contact with the insurance company multiple times and they've confirmed that they've contacted the office with no reply. When we've called the office , we've been treated as though we're in the wrong. I will be contacting the Dental Board of California regarding their potential illegal billing practices. I'm not usually one who yelps but this is not right! My suggestion is know what your coverage is and go somewhere else. Pay attention to these yelps . Had I done that prior to this I would've seen all the poor reviews this business has had. read more

What happened to this place? Used to be good when they first opened...now years later they try to up sell you on everything. The back staff seem cool, but front office needs work and organizatThey call other members of your family to report an appointment which is a violation. They say they call to remind you of your appointment but called a wrong number and voicemail is full. And they seem to lose track of when you prepay for services and don't have record of it! Won't be back... And stop calling my number about appointments!! You guys are in violation of HIPPA laws! read more

These people are a mess. The receptionist in the front are rude and unfriendly. I took my son in having the best insurance and they are billing me instead of my insurance and putting me in collections. I have two sons this has never happened in any dental office that I've been to. It seems like they have a continuous turn over of receptionist who don't know how to bill properly. Poorly Under trained staff. read more

Ladies in the front are always kind. My son had a hard time at the dentist when he first started going due to some sensory problems, the dentist and all the staff have been very patient with him and after almost a year with them my son has grown to like going to the dentist. They have taken great care of my son's dental health. I look forward to able to continue to take my son here. read more

Great dentist and great staff! They all make you feel welcomed. Had a deep cleaning and the technician was very gentle.

My family and I have been coming here for several years. The staff are always pleasant... from the front desk, x-ray technicians, dental hygienists, and doctors. Dr. Leng is so kind and does great work. The environment is comfortable and spacious. I'm happy to be able to bring our son here for his dental and ortho needs. He's in good hands read more

AWFUL AWFUL AWFUL!! Never have appointments available and don't even call you to cancel your appt. missed an hour of work for no reason!!!! Front desk staff is horrible!!! Please DON'T GO HERE!!! Ridiculous!!!! All dentist are freelance and are never available Save yourself the time and $$$... plus their prices all over the place... my family of 6 all go and we had the same cleaning services, extraction, ortho, etc. and all prices were quoted differently!!! They didn't know we were all related. They look like fools!! read more

This place is sooooo crooked, they always go to the most expensesive treatment and make it sound like it is your only option. My wife went they wanted to charge 1,000 for a repair, they made it seem to be her only option, she went to her old dentist they did the repair for less than $200. Times are tough they should discuss the cheaper option and work their way up... read more

I don't think it is right for you the let you patients wait outside when it is over 90 degrees HOT outside . And tell me what are those distanced chairs you placed inside for? We told you that we were fully vaccinated and yet you insist to let us out! You should be more considerate to your patients. You should re-evaluate your regulations . We don't deserve this kind of treatment! read more

Rude staff. Vanessa C is always bothered when you ask her questions and would prefer if you discuss payment over email without questions. Don't go here. They tried to charge 1700 for wisdom teeth removal after insurance. The staff is always talking bad about other patients and they never call you back when they say they are. They're always making faces and apparently can't answer your questions. Go somewhere else . read more

This place is HORRIBLE, stay away. They need to get rid of the entire front desk staff. Over charged me after having me sign off on one bill I agreed too, months later it's more money to pay which now they're saying the insurance didn't cover but at the time of services they told me the insurance covered it. These people are insurance scammers. I'm personally having them investigated and once I spoke to them about their mistake and that I'm having everything investigated they quickly sent my account to collections. read more

Stay away. I don't think it's the dentist. The issue is the staff at the front desks. Customer service is terrible. Had to call 8 times to get my bill for my fsa out took 6 days to get my bill. They are also very rude. My son is 4yrs old and treat him like he insulted them. I'm finishing my treatment, I hope they don't mess up the billing for that again, then I'm done. I advise you to take your business somewhere else. The front desk staffs are terrible. Stay away from this place. read more

I love the friendly staff, especially Gina at the front desk. Always happy and willing to help. I would definitely recommend this office to anyone who is looking for professional dentistry. read more

I chose this dental office because it was convenient and attended a few times. There was scheduling issues due to their computer system often However, the most concerning was the following. I was told I needed a filling replaced which would cost to my insurance and $1k out of pocket. I decided to wait since I had no pain. Six months later I return and I'm told I need a whole crown. They were charging my insurance plus $2k out of pocket. For one tooth. The whole thing did not seem right. I saw a very well recommend dentist in another city who was surprised about the previous findings and said I definitely did not need a crown. And on top of that, I didn't even need to replace the filling. It was optional. This office should be embarrassed to not only practice unnecessary procedures for pure profit. But also overly quote people and take advantage of their ignorance. I would never recommend this place to anyone read more

I had been a dental assistant for 35 years, so am a little picky about my dentist. Since I retired I have seen 6 dentists, none of whom I thought was good or caring or as honest as they should be. A couple never even introduced themselves, and was in and out in a couple of minutes. Another told me that if we didn't buy their tooth rinse that they wouldn't see us again at all. The last one told my husband he had 16 fillings that needed to be done, although he had none 6 months before and has none now. Ths dentist is really great and spent a lot of time with my husband and I and was really nice, but not pushy. Blanca cleaned my teeth VERY WELL and for the 1st time in years I felt like I had a good cleaning. The other dentists just polished, which is not a cleaning at all. This office is great, and does good and honest work, and I highly recommend them! read more

STAY AWAY STAY AWAY ! Total rip off. After you talk to the dentist, they send a sell specialist in there to try to hustle you if you go over the break down it does not even make sense. To get your teeth cleaned they are charging $700 with insurance !!!!! I nee I FEEL LIKE I WAS BUYING USED CAR ! THEY MADE ME FEEL SUPER UNCOMFORTABLE!!!!! read more

first visit here I waited in the lobby for almost an hour to be seen, despite being on time for my appt. after calling me back i sat in a chair for around another hour before the doctor came to see me. i'm surprised i came back after that. after i got my quote and exam done, i called back a few weeks later to schedule a cleaning and ask about some insurance changes - to which they said they'd call me back. i called back and forth with them FIVE times before getting an answer despite being told id get a call back every time. After calling back the last time I was able to finally schedule an appointment, and upon arriving they said "they don't have me down for that, and need to see if they can fit me in" despite me being very clear over the phone on what i wanted to come in for. the receptionist blamed it on "call center" - which isn't true because i recognized the person I spoke to from coming in before. they're lousy and slow here, obviously not caring about your time. read more

Oh man this place is a total rip off extremely over price with or without insurance. Do not go here. If your insurance issue of you this please call them back and tell them you want a completely different office the sales people remind me of used car salesman they try to sell you procedures you do not need at extremely expensive prices. And if you say OK well thank you and walk out they look at you crazy like if you're making a bad decision lol I don't know how this place is actually still in business with all these bad reviews and crazy prices literally quoted me $1900 for a deep cleaning, it is wild I'm not sure what they are thinking then they're pressing me to pull out my wisdom teeth when they're not even bothering me at all so they can make another $4300 I just got up and walked out of there as soon as I can. so I'm going to save you the time don't even consider this place. read more

I phoned Triangle Dental Group based on referral for general dentistry and Orthodonctics. After speaking with Sharon she is knowledgeable, thorough, and helpful. I can say we feel absolute sure about seeking Triangle Dental Group for dentistry work. One might question making a choice based on one phone call; however, with all the knowledge, professionalism this person demonstrated it is yes for us. Also, you can tell by the sound in her voice she was happy and likes what she does. These are great qualities for any employee to demonstrate and qualities the employer should acknowledge. Thank you Sharon for your time and efforts; and, thank you Triangle Dental Group for having such an outstanding employee. :D read more

Horrible service. They set you up on payments, and tell you when your last payment is but then one day out of the blue you get a bill. Wtf? Called them up and they tell you "oh yeah, well our system doesn't calculate the last payment." They will tell you one thing, then you come back and they tell you another or don't even bring it up. I could write a novel. Yet, their other office up the street is excellent! Place is a joke..... just waiting to finish my contract, then finding another dentist/orthodontist. read more
