Some of our Services

Invisalign

Invisalign offers adults and teens a more cosmetic, comfortable and convenient alternative to other types of orthodontic appliances. Designed to move teeth through a planned sequence of clear aligners, Invisalign is virtually invisible to the outside world. Transforming smiles with minimal interference to daily activities, Invisalign allows teens and adults to enjoy eating all of their favorite foods, and engage in sports without the fear of breaking their orthodontic appliances or sharp poking wires.

AcceleDent

AcceleDent is a compact, hands-free orthodontic device designed to be used alongside braces or clear aligners to help speed up tooth movement. Worn for just 20 minutes a day, the device delivers gentle micropulses to the teeth and surrounding structures. The goal is not to replace traditional orthodontic mechanics but to complement them, helping patients reach their treatment milestones more efficiently while maintaining the carefully planned direction set by the orthodontist.

Traditional Braces

The most common type of braces seen today, remain “metal braces”. Made of high-grade stainless steel these braces are significantly smaller and have a lower profile than their predecessors from years ago. Each brace, which is known as an orthodontic bracket, is individually bonded to the front of each tooth. Metal braces allow for efficient and highly controllable tooth movement.
