Today’s braces are very high-tech appliances. Over time, they straighten your teeth. Here’s how they do it:
Braces have three basic parts:
- Brackets made of metal or ceramic. A bracket is attached to each tooth.
- Bonding material (glue) or a metal band. This is what attaches the bracket to the tooth.
- An arch wire, which is a thin metal wire that runs from bracket to bracket and puts pressure on the teeth.
The teeth move when the arch wire puts pressure on the brackets and teeth. Sometimes, springs or rubber bands are used to exert more force in a specific direction. Braces exert constant pressure, which over time, move teeth into their proper positions.
