I've been coming here since March of 2021. So far, I am satisfied with their periodontal treatment. Appointments were fairly easy to make, since they were willing to see me within the week, compared to a couple of months out with other periodontists. I came for an evaluation of a loose molar, which Dr. Li said sadly, must be taken out. After that part, their administrative staff also gone over with me necessary treatments, and how the implant installation works per step, and also how the insurance, and my own payment, will cover it. They also advised me the amount of possible pain for each step, which to me, was tolerable. Even though my general dentist only noted the loose molar, and referred me to the periodontist, Dr. Li also recommended additional work in other areas once the molar implant is done. It shows me she cares more about her patients' dental health than general dentists. I do look forward for my implant result, and work on the other areas as well. read more

Bad Experience at This Dental Clinic I had a very disappointing experience at this dental clinic and feel it is important to share it so other patients are aware. 1. I had a dental implant done at this clinic, but it later had to be removed due to severe pain. I do not feel that the potential risks or complications were clearly explained beforehand. The entire experience was very painful and frightening. 2. The clinic was out of my insurance network, but this was not clearly communicated when I called to make the appointment. Instead, I was only told about the financial details after I had already arrived and was seated in the clinic. Patients should be informed about insurance status before the appointment so they can make an informed decision. 3. I was charged additional money for a very simple procedure (just placing a loose crown back in position). The cost felt unreasonable for such a minor treatment. 4. A full-mouth X-ray was taken even though it did not seem necessary in my situation, which resulted in additional radiation exposure and extra cost. 5. The financial staff member provided an explanation about the charges after I sit in the exam chair. the discussion felt somewhat forceful and made me uncomfortable. It did not feel like there was much room for open conversation. Overall, the lack of transparency regarding insurance, costs, and treatment decisions made this experience very frustrating. I believe patients deserve clear information before treatment so they can make informed choices about their care. read more

You shouldn't rely solely on advertisements. All problems such as implant fracture and detachment are the customer's responsibility and have nothing to do with you. And they even used the most expensive brand. It's frustrating, but I can only accept my bad luck。 read more

This is the absolute worst dentist I've ever been to in my life. I am shocked at the high ratings they have. First of all, they call from a bunch of different numbers when you do call the number that's on the insurance card, someone answers and they don't speak a word of English. I took my son. He's two years old and he has cavities so they told me I need to wait for something in the mail to come to be referred to a different dentist for him. It's been two weeks, and I still have not received a thing. I call them and no one calls me back. Do not waste your time if you need your teeth fixed or if you need your kids teeth fixed! Definitely go somewhere else because this place does not care about you. read more

Dr. Li did 6 dental implants for me last year. My front teeth look so great now. I have gum disease for years and I feel so lucky to find Dr. Li. She is very professional and knowledgeable. She recommended gum surgery to save as many teeth as possible for me first. Then for the real loose teeth, she removed them and place dental implants on the same day. I didn't feel any pain after surgery. BTW, the implant price is very reasonable and front staff offer the no interest monthly payment option to me too. Thank you Dr. Li! read more

I can't thank my doctor and their team enough for giving me the perfect smile! From the very first consultation to the final adjustment, every step of the process was handled with care, professionalism, and a personal touch. The office is always welcoming, and appointments are efficient yet thorough. Definitely the go to! read more

Worst Dentist I have ever had, seemed impolite and rude. During the cleaning his assistant constantly pointed the water jet to the back of my throat, causing me to gag continuously. Even after numbing my gums, this was the most painful cleaning I have ever experienced, will never return. read more

Got my beautiful smile here at diamond dental specialty. The office and staff were wonderful especially Ulan and Dr. Dan. They took care of all my needs and questions from beginning to end. Highly recommend diamond dental specialty. read more

Got my gum surgery and implants done here. Dr. Jingjing Li and staff were amazing. I was missing some back teeth and had red swollen gums. After several sessions with Dr. Li my gums have healed and now I can chew on my back teeth like I used to. Trust me, you won't know how it feels not being able to eat like normal until you lose your teeth. Overall I am very satisfied with my experiences at Diamond dental specialty. read more

Reply to Owner's comment: Her response to my review does not address any of the substantive issues that I raised regarding frivolous and gratuitous upselling. Noticed she took the opportunity to continue to blow her own horn and was "triggered" enough to defend her photoshopped phony image with the white lab coat. She also had to plug/reiterate all the fancy ABC alphabet soup rubberstamps to "prove" her qualifications. Don't worry I can see through the façade. Sad and pathetic! read more

Great care, great professional. Always answered our questions and was willing to take the time and explain the procedures and the importance of them read more

The doctors from China are not professional at all. They chose this clinic because they said they could accept Medicaid. At that time, I went to the clinic to check my teeth, and without my knowledge, they said that I had 5 cavities filled. Actually not that much. It's all about trying to scam money from my insurance card. I also lied to me and told me to do a deep cleaning, but Medicaid did not include this item. I paid $300. On the same day, I was given anesthesia and quickly did all the deep cleaning of my teeth. Later, I changed to another clinic and the dentist told me that the deep cleaning is done in two parts, not in one time. So I got scammed again. read more

The service here is very good. All staff are friendly. love my smile. the dr. was professional and knowledgeable.

this is the worst dentist ..they pulled out my teeth without telling me clearly. They had bad attitude

AVOID DR. NGUYEN PLEASE!!! I would give this place a zero star if I could. Receptionist is really rude and kept calling me by a wrong name. Dr Nguyen is super impolite and rude. He never really listens to you. He scolded me and said I'm ridiculous because my brackets fell off twice. Like come on bro, isn't it normal when your brackets fell off a few times during the procedure? Even if this is not common, isn't being patient and polite to your patient a basic principle to a doctor? Like wtf... Come on, he is actually the RIDICULOUS one. After saying that, he and his assistant pulled my face really hard to put the new brackets on as it was on purpose. Anyways if I can file a report for this place and doctor, I would definitely do. This is bully and extremely rude. I have no clue what I do wrong to make them against me this me. I don't think it's appropriate for anyone to ever do that. Besides that, he's also really unprofessional. The procedure took more than three years already. It was already ridiculously long and he never found I had an extra tooth that blokes my teeth moving. He just never listens to what patients complaining about. Overall it is the worst experience I've ever had with a doctor. Anyways I have switched orthodontist. Wish you good luck if you have him. read more

I just got my tooth implant done here two days ago and I am more than pleased with the results. All my relatives saw my teeth today at Thanksgiving and loved my new smile. I can eat like normal which I had a hard time for years now. I should've gotten my implants done sooner if I had known what I have been missing all these years without my natural teeth. read more

The attitude of receptionist is really bad! After consultation, she refused me to pay by cash with the discount price at first (which they provided the price when I made the appointment) , and was forcing me to use my dental insurance to charge more. You need to be really Clear with the receptionist about the bill before you visit the office. read more

After 3 years of patience and consistency.. my smile is finally finished, all thanks to the great skill and expertise of Dr. Dan.. I walked in and as soon as treatment stared I felt taken care of.

Let me start of by saying that after months of searching Im soo glad to have found Dr Li. She and her staff are beyond amazing and professional! from the moment I walked in I was nicely greeted and seen on time which is very important to me, Dr. Li was very knowledgeable, detailed and upfront about my dental Implant treatment and bone surgery . I was very nervous at the beginning but she made me feel comfortable during the whole procedure, explained everything she was doing and now Im very satisfied with my Implant. Overall it was a great dental experience! I would definitely come back to have my cleanings done here as well and will recommend to my friends and family. Thank you so much Dr. Li and staff, I look forward to my next visit! read more

I neglected my dental health for a while now and it was time for me to get a check up and cleanings. I went to Diamond Dental Specialty upon a recommendation from a friend and was not disappointed. Dr. Li is an amazing periodontist with great chair side manners. I was very comfortable with her and her diagnosis and got my cleanings and periodontal surgery done. Now my teeth are feelings stronger and should I need implants for my neglected teeth in the future I will definitely have Dr. Li do the implants. Furthermore the prices are affordable. I highly recommend Diamond Dental Specialty. I don't understand where that one negative review is coming from. I highly question the woman with the negative review. I read it and it seems all her reviews are negative towards doctors, lawyers and even the public library ! it just shows that you cant please everyone. read more
