What Is Invisalign?

If you have teeth that are crowded, too far apart or have moved since wearing conventional braces, Invisible Braces by Invisalign or Smilelign may be the answer for you.

Being nearly invisible, almost no one can tell you are wearing Invisalign or Smilelign braces, so you can smile more during as well as after your treatment. These braces are removable so that you can eat and drink what you like. Studies have shown that the invisible braces can be better for your dental hygiene during treatment. There are no metal or sharp edges with the invisible braces, and so are comfortable to wear and do not cause allergies.

The convenience and ease of use of invisible braces have made it the choice of over half a million dental patients, giving hundreds of thousands of people amazing new smiles.

How Do Invisalign Braces Work?

Using the latest 3D computer technology, custom made removable mouth trays (dental aligners) are created under the dentist’s instructions. A series of these dental aligners are worn over the course of treatment, all slightly different, moving your teeth gradually into the desired position.
