Our Clients Reviews

Sayville Family Dentistry has been taking care of my teeth for many years now and I can honestly say that they have provided excellent care in a friendly manner. We go every 6 months & I recently had a checkup last week. Doctor Udeshi & Hygienist Kay Mertens know their business and have provided all my dental care without trying to push me into unnecessary procedures, I totally trust their recommendations to be what I need & their work is top notch. My wife and myself highly recommend their practice for your dental care.

– Bill Elia

I see Dr. Udeshi twice a year for check ups, she is friendly and knowledgeable as she answers all my questions on my teeth issues. I am very satisfied with the work she has preformed on my teeth. The dental hygienist, Kay, has been cleaning my teeth for years, she goes out of her way to insure you are as pain free while your cleaning teeth. If you want to keep you teeth, all you have to do is follow her advice. I did and as a senior I still have my teeth for over 15 yrs. Kay has a wonderful personality; she is kind, friendly and non- judgmental. I look forward to my appointments with her.

I had the best dental experience ever . I’m a dentist and I’m a super phobic.
I ended up fracturing a tooth and Dr. Udeshi fixed it. It was a completely painless experience. Very friendly staff and an efficient dentist made it a pleasant experience.
I would only trust Dr. U with my teeth!
Highly highly recommend .

Dr. Udeshi is outstanding! Kay, the hygienist is fantastic. The entire staff are professional and so nice! (I was there on 6/22/21, I don’t know everyone’s names yet). They go out of their way to make you comfortable and help you. I highly recommend Sayville Family Dentistry. This practice is a little jewel in Sayville.

Dr. Sandhya Udeshi, Kay and her team are committed to providing the best in preventative, restorative, Implant and cosmetic dentistry.
My Family has been using them for the past several years. I have required extensive complex dental work which among others included a bridge to multiple front upper teeth. Having a severe overbite I had been told by another dentist that this could not be done. Understanding its complexity she referred me to consider other Dental/surgical options. After fully explaining my options and providing informed consent she completed this procedure approximately 2 years ago and I have had an excellent cosmetic as well as functional result that greatly exceeded my highest expectations. Dr. Udeshi has a fine educational background and in addition to being very bright has excellent fine motor skills. She also puts the best interest of her patients above her own.

In summary, I am not a friend or family member of anyone from this team and highly recommend them without reservation.
