An orthodontist is a dentist who specializes in straightening teeth and correcting problems with how the teeth and jaws fit together.

They commonly treat:

• Crooked or crowded teeth
• Gaps between teeth
• Overbites and underbites
• Crossbites
• Jaw alignment problems

Orthodontists use treatments such as braces, clear aligners, retainers, and other dental appliances. They complete additional specialized training after dental school.
