Treatment options
There are numerous dental treatments available that align your smile. Let’s discuss each procedure in more detail.
Treatment | How It Works |
|---|---|
Clear aligners | These lightweight, ultra-discreet trays exert pressure onto the teeth, encouraging them to gradually move into their correct position. |
Fixed braces | Similar to clear aligners, fixed braces move your teeth into alignment. This type of brace is attached using metal wires and brackets. |
Nanofill Composite Bonding® | Nanofill™ offers a quick cosmetic fix. The exclusive procedure disguises your malocclusion with a bright, hard-wearing resin that lasts up to eight years. |
Tooth extraction | This is often recommended prior to treatments such as fixed braces. Why? It helps to create space in your mouth and allow your teeth to move. |
Surgery | In some cases, your dentist may suggest surgery to not only reposition the jaw, but also make the facial features appear more symmetrical. |
