Dr. Sarah Balaster received her Doctor of Dental Medicine from Rutgers School of Dental Medicine and earned her certificate in Periodontics from the New York University College of Dentistry. Prior to enrolling in dental school, she attained a Bachelor’s of Arts with honors in Fine Arts from Wesleyan University and a Bachelor’s of Science in Biology from William Patterson University.
Dr. Balaster’s background in both the visual arts and sciences allows her to work with patients to achieve both an esthetic and healthy smile.Dr. Balaster prefers to treat patients with minimally invasive surgical therapies when possible and is trained in the LANAP protocol; which offers a less painful, treatment alternative to conventional periodontal surgery through the use of the PerioLase MVP-7 Nd:YAG laser.
The LANAP treatment can target the source of the inflammation without hurting or removing any healthy gum tissue to slow or stop attachment loss, decrease pocket depth, and allow the body to recover from the chronic infection without the need for scalpel or sutures.
The LANAP protocol is the only laser treatment protocol currently cleared by the FDA for true regeneration and is backed by both clinical, scientific, and human histologic evidence.
Dr. Balaster has worked on the development of soft tissue (gum) grafting techniques to improve esthetics, function, and patient comfort. Her surgical techniques are evidence based in biology and are tailored to each patients needs and unique situation.
She believes both periodontal and surgical treatment are not one-size-fits-all and that each patient should be thoroughly evaluated and diagnosed prior to selecting both treatment and surgical technique.
She is a member of the American Academy of Periodontics, Northeast Society of Periodontics, American Dental Association and the American Laser Society.

The care I received at Family Dental Group in Fishkill exceeded my expectations. I went in to have all my wisdom teeth removed and from the moment I stepped in for the initial consult, the receptionist and staff were friendly and accommodating. They answered all my questions, were friendly, and made me feel comfortable with the procedure I was to have done. The day of, everything was ready for me…

I am and have always been a very nervous and scared dental patient. After being absent from visiting any dentist for years, I decided it was time to be brave and give it a go. I restarted at Family Dental a few years back and they have always made me feel comfortable and at ease with any treatment I needed. I’ve had 4 wisdom teeth removed and a couple of fillings and I get my teeth cleaned e…

I went in on 8/30/17 for an initial consultation. I saw Drs. Oh, Ayuke, and Chernim. I was told all my teeth needed to come out (about 15 that were left). The consultation lasted about 2 hours total and in that time they answered all my questions, never made me feel rushed, and explained to me everything that would take place. The staff was amazing! I am terrified of dentists and was immediately p…

In an expression of utmost gratitude I would like to thank Dr. Gelbart & his amazing staff for their contribution to the recovery efforts in Puerto Rico. A donation of nearly 1000 toothbrushes toothpaste and dental floss have been distributed to the children of the storm ravaged town of Morovis, Puerto Rico who just recently returned to school 3 months after the devastation occurred. Thanks a…

I have an extremely high fear of dentists and had not been in over 30 years. Dr Neil Kesselman and his staff are incredible. Compassionate and caring and even though my fear isn’t gone I now know it’s not as bad as I thought it was. Very grateful to have found them and highly recommend them to anyone. Especially to those like me who are super scared. Dr Kesselman is very thorough with…

I went to Family Dental of Fishkill for the first time 2 weeks ago. I used the same dentist for over 30 years so I had a little apprehension to say the least!

I have been to this dental office for about 15 years. I may be a dentist’s best case scenario because of my relatively excellent oral/dental health (or was that a dentist’s worst case scenario ;-). However, I do have my cleaning done at the Family Dental Fishkill 3-4 times a year. And I think the Fishkill office has one of the best dental hygienists, Leisa! Her professionalism, the way…
