Braces require a dentist or orthodontist to glue a small bracket to each tooth using dental cement. A wire is then fed through each of the brackets with a tight band placed over the wire to secure it to the bracket beneath. The tension of the wire and the band creates a pressure that slowly moves the tooth into alignment. Every couple of months the braces are tightened to pull the teeth further into position.
Braces are fitted to correct the alignment of the jaw and to move teeth for aesthetic purposes. They can be fitted for anywhere from six months to two years.
