Sarah Balaster, DMD  Periodontist

Dr. Sarah Oshman Portrait

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.
