Our practice was started by Dr Frank Kestler in an effort to provide the East End of Long Island with a place where dental patients would be comfortable with their care. Dr. Kestler is a second generation dentist and learned a lot about how to treat his patients from his father. As a Colonel in the United States Army Reserves Dr. Kestler has protected our country in Iraq and is as dedicated to your care as he is to our country.
Frank Kestler obtained his D.D.S. degree in 1987 from NYU College of Dentistry in NY, NY. Initially, he practiced dentistry in Queens County and the Bronx, NY. In 1993, he began working as a Dentist on Eastern Long Island. Today, he is proud to be able to offer his patients the convenience of his services in two locations.
It is our belief that a child's relationship with his or her dentist will inspire good habits and decrease future oral problems. Our staff is specially trained to make the youngest of patients more comfortable. We take our time to examine your child. We explain the processes that we use and why we need to take care of our teeth.
We understand that paying for dental care can be difficult. Our goal is to help as many patients as possible receive dental treatment whether or not they are covered by dental insurance. The cost of your treatment may vary depending on your individual needs and treatment plan. We will discuss with you the cost of your treatment and your available payment plan options before you begin treatment so that you can make the best choice for your dental health.

I finally got an appointment.3 weeks waiting with the pain. And.unbelievable. Someone took full mouth XRay and after refered me to tooth extraction and root canal. When I asked why I have to look for another doctor and where is Dr. Kestler she said he is not working in Mattituck and none of any doctors of his team works here. What is the purpose of giving wrong information on their website.?

I have extreme anxiety about dentists. I was in and out of dental offices my whole life practically. They are very warm and inviting at this office. Very thorough and polite and genuinely care about your feelings. It made my experience wonderful and I was a lot more at ease. Thank you!

Eva was wonderful. She really did a fantastic job cleaning my teeth after my last cleaning 3 years ago. She was very professional and pleasant and was not judgmental or negative which made me feel comfortable. She is an asset to the practice, and I will request her for cleanings in the future. Thank you Eva!!

I used to be scared of going to the dentist. So I often delayed going at all... But not since meeting Dr Frank Kestler and all the lovely staff at their North Fork, Mattituck NY location. After many root canals - that were virtually painless - I can honestly say he is my favorite dentist. Now I have the nicest smile and dont fear the dentist anymore. Highly recommend.

Dr. Seider is by far one of the best dentist on the island! I've been going to him for over ten years now. After moving to Florida and having a terrible experience with a dentist, both with pricing and quality of work, I decided to plan my dentist appointments with my travel for holidays just to get work done from him. He takes his time with each patient and makes sure you are in absolutely no pain! which is different then a lot of other dentists in my experience. He also is very fair with his prices and still provides top quality work. I highly recommend going to him for any dental work!

After 35+ years of dentistry this office is the best. Dr. Salkin is my treating dentist and is amazing. Dr. Kestler has a great team.

What a great dental experience I had here. The office was decorated so nice. Everyone was so pleasant and best of all they took my fidelis insurance. I didn't feel rushed, they were very thorough. Looking forward to my next visit.

Super friendly staff and a BEAUTIFUL office! So much fun to come and see all the holiday decorations – all year round for Easter, St Pats Halloween etc. Make it almost a joy to come to the dentist :0 Everything was explained very well and I wasn't pressured into receiving any additional dental treatments. They remind me of my appointments. Also Dr Kestler took extra time to create a dental treatment plan that worked for my need and my insurance coverage.

At first I did not understand and he was very patient with describing all the dental work that I needed. Already have started on my work and so far it is going well – very little to no pain.

This office is so nicely personalized in their dental care and business dealings. Dr Frank Kestler and his team do a really good job of keeping my teeth in great shape. Dr discussed the dental services and exact step by step process so that I understood what was being done and why . This dentist and his superior talents and reasonable pricing has kept me coming back even though I have moved out of the North Fork of Long Island NY. I recommend them strongly to everyone.

I am terrified of the dentist, both Dr Kestler and his staff took their time, and walked me through every step of the process. This is the first time ever I have not needed gas for a procedure!
Ginny McCaffery
I had a root canal done yesterday and it was my first root canal with Dr Kestler. I am still amazed that I never felt the shot of novacaine or any of the procedure. I am very impressed as I have had a few root canals over the years and usually experience pain during the procedure and worse pain afterwards... Dr Kestler and his staff are professional and sympathetic to your needs.. I have quite a bit more dental work to go but am at ease now about getting it done. I highly recommend his services!

I truly believe Dr. Kestler is the best dentist I've ever seen. Myself, my husband and our 4 year old son were just in to see him today and left with big smiles on our faces. They have all top of the line equipment so it's virtually pain free not to mention both Dr. Kestler and the hygienist are amazing with children. I would recommend his practice to everyone, especially if you are in pain, they are the best!
