Suffolk Pediatric Dentistry and Orthodontics has taken care of children's teeth for over 40 years. In fact, our practice is one of the first pediatric dentistry providers in Suffolk County. Many of the parents who bring their children to our offices in Port Jefferson Station or Wading River were patients of ours when they were children too. Kids know us for our friendly staff and iconic tooth-on-a-banana-chair logo, but parents know us as competent, caring professionals.

Our pediatric dentists and orthodontists have a keen understanding of the psychology involved in treating children. Whether your child is visiting for orthodontics, a routine cleaning, or having a cavity filled, we will provide them with the support they need for a successful procedure. Find out why two generations of Suffolk County residents have chosen Suffolk Pediatric Dentistry and Orthodontics for their children's oral health needs.

Suffolk Pediatric Dentistry and Orthodontics provides a full range of dental services, including:

Preventive and Diagnostic Services​ – Part of our job as pediatric dentists is to lay the foundation for a lifetime of good oral health. This includes dental cleanings and exams every 6 months, along with hygiene instructions to give children the tools they need to take good care of their teeth.

Restorative Services​ – Cavities happen. When they do, we're here to help. We offer amalgam and composite fillings, pulp treatment, and dental crowns to restore health to decayed or damaged teeth. We also offer extractions when the best course of treatment is to remove a tooth.

Cosmetic Services​ – When a child chips a tooth, we can use cosmetic bonding to restore its appearance. For teens who have recently had braces removed or have staining for any other reason, we offer whitening treatments to give them confidence in their smiles.

Interceptive Orthodontics​ – The goal of interceptive orthodontics is to minimize or eliminate the need for orthodontic treatment once a child's adult teeth have come in. These treatments include habit appliances to stop thumbsucking and re-train improper tongue position, space maintainers, and molar rotation.

Orthodontics​ – Our practice offers both traditional metal and ceramic braces as well as Invisalign Teen and Adult Invisalign. Once treatment is completed, we will provide a retention device to make sure your teeth stay in place.
