I'm a mouth breather that eats a lot of candy and have destroyed all my back teeth. my front tooth had an infection in the bone and fell out. I went in for maintenance on my front teeth since I couldn't handle anymore teeth gone. It's going to be a big ordeal for me to get a partial since I have no teeth in the back barely, but somehow ANGEL Dr. Dalia Niknam 🩷 MADE me a tooth to stay miraculously! like a God sent wizard 😄😍🙏💕 I was praying hard but I never even thought that was possible and I didn't expect it. I was shocked she said she just wanted to give me some happiness. It did. It has increased my faith in God and the kindness of others forever. Thank you God and gorgeous Dr. Niknam and every lovely sweet beautiful person working at Advanced Dental. 🙏🥲💕💕💕💕🙌 I thank you and ask for your blessings in my prayers forever. 😭🥲🥲🥲🩷🥲🩷🩷🥲🩷😄💐💐💐💐💐🥲🩷♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

All the staff including dentists are very kind,helpful and knowledgeable. The dentist helped me to find the pain in my tooth. I thought it was a cavity. But it was a bacterial infection. I was so happy to get the service from them.

I came here when I had an infection, and Dr. Z quickly prescribed an antibiotic that had me on the mend. That's where my 3 stars 🌟 stop. He referred me to Dr. N, who specializes in TMJ and implants. I understand insurance limitations, but Dr. N persistently tried to upsell me on services that weren't covered. I get that it's a business at the end of the day. During my last visit, I was genuinely trying to give them my business for two crowns, which required insurance pre-approval. Dr. N told me she couldn't perform the procedure because I needed more gum/tooth space and a more in-depth procedure first, one she wasn't sure insurance would cover. She essentially told me to return to the original office that did my initial fitting because she couldn't help without the preliminary gum work. Yet her staff still submitted a referral to my insurance for the very crowns she said she couldn't do. I even have a text exchange where I informed the front office that Dr. N said she couldn't do the procedure, even after they contacted me to say my insurance approval had come in. To top it all off, they called and left a voicemail later because they still had the pre-approval on file and mentioned it was only good for a few more months. I don't know which is worse: the consistent upselling or the severe lack of communication with their office.

Had my chain readjusted for my expose and bond by Dr Eshaghzadeh. Great and fast procedure, friendly and amazing staff, very reasonable pricing, and virtually zero pain after the surgery. My tooth is coming in now and looks great! Hoping it comes in place soon but the procedure is definitely speeding it up. Thank you!

The best dental practice. Dr. Niknam makes sure that I am comfortable and provides the best treatment possible. My whole family loves her because she is real honest and transparent with what treatment we need. The front office and back office have great customer service and always have a smile. I like the reminders messages the office sends prior to my appointment with my busy schedule it’s very helpful to get the reminders. The office is very clean. The staff is very helpful. If you are looking for the best dental care Advance Dental Group is the right place.
