Orthodontic Treatment In Southampton, NY
Comprehensive orthodontic care designed for comfort, confidence, and lasting smile changes.
Your Smile, Our Passion
Precision Care
Orthodontic treatment should do more than straighten teeth. It should improve alignment, support bite function, and create a smile that feels healthier, more balanced, and more confident in everyday life. That is why every treatment plan is built around the smile, the bite, and the patient, with recommendations shaped by age, development, and the kind of result that will hold up well over time.
Meet Dr. Cartier
For decades, Dr. Michelle Cartier has had the privilege of creating beautifully aligned smiles for patients across the Hamptons. What continues to shape her work is not only the transformation of a smile, but the confidence that comes with it.
Dr. Michelle T. Cartier, DDS, CAGS, earned her DDS from Georgetown University Dental School and completed her orthodontic specialty training at Boston University. She has been creating smiles since 1995 and has been board certified since 2012.
Patients trust Dr. Cartier not only for her credentials, but for the way she delivers care: calm, precise, and centered on the individual. Every treatment plan is built with close attention to both appearance and function, so the result feels balanced, healthy, and built to last.
Smile Transformations
Every smile transformation should look natural, feel balanced, and support the way a patient lives day to day. Whether treatment involves braces, Invisalign®, early intervention, or more complex correction, the goal is always the same: a result that improves alignment, supports function, and leaves patients feeling more confident in their smile.

Frequently Asked Questions
What does an orthodontist do?
An orthodontist specializes in correcting the alignment of teeth and jaws to improve your smile, bite, and overall oral function. We create personalized treatment plans based on each patient’s age, dental development, goals, and orthodontic needs.
When should someone see an orthodontist?
An orthodontic evaluation can be helpful for children, teens, and adults. Early evaluation can identify developing alignment, bite, or jaw concerns, while adults can also benefit from treatment to improve the appearance and function of their smiles.
What happens during an orthodontic consultation?
During an initial consultation, our team evaluates your teeth and bite, discusses your goals, explains potential treatment options, and develops a personalized treatment plan. We can also discuss financial information, insurance options, and available payment plans.
What technology do you use for orthodontic treatment?
We use advanced diagnostic technology, including iTero digital scans, CBCT scans, panoramic X-rays, and cephalometric X-rays. These tools help us evaluate your teeth and jaw development and plan treatment with greater precision.
What is an iTero scan and how is it used in orthodontics?
An iTero scan creates a detailed digital impression of your teeth without the need for traditional dental molds. We use digital scans to evaluate your smile, show you what your treatment may involve, and assist with treatment planning for Invisalign and other orthodontic treatments.
Can adults benefit from orthodontic treatment?
Yes. Orthodontic treatment isn’t limited to children and teenagers. Adults may benefit from Invisalign, clear braces, or metal braces depending on their teeth, bite, oral health, and treatment goals.
How can orthodontic treatment improve more than just the appearance of my smile?
Orthodontic treatment can address tooth alignment and bite concerns while improving the function and balance of your smile. We focus on both aesthetics and how your teeth and jaws work together when developing a treatment plan.
How often will I need to visit the orthodontist during treatment?
The frequency of appointments depends on your treatment plan and individual needs. Most patients visit us periodically throughout treatment so we can monitor their progress and make adjustments when needed.
Do you provide orthodontic treatment for children, teens, and adults?
Yes. We provide personalized orthodontic care for patients at different stages of life, including children, teenagers, and adults. We consider each patient’s dental development, bite, goals, and individual needs when recommending treatment options.
