If you have crooked teeth and a misaligned bite (an overbite or underbite), there are a variety of treatments that can help straighten teeth including braces and retainers.
The braces may consist of wires, bands and other fixed or removable corrective appliances. No one method works for everyone.
In their entirety, over a period of time, braces work by applying continuous pressure to slowly move teeth in a specific direction. As the teeth move, the bone changes shape as pressure is applied.
