Also known as a "brace" is an orthodontic attachment that is secured to a tooth (either by bonding or banding) for the purpose of engaging an archwire.
Dental misalignment caused by inadequate space for the teeth.
These are the marks or "scars" left behind when bacteria or soda acid is allowed to remain on the teeth for extended periods. Proper brushing and flossing along with a healthy diet can prevent these.

These small rubber bands are used to move teeth in a prescribed direction.
These devices are used to move teeth or affect the growth of the jaws.
The tissue that surrounds the teeth, consisting of a fibrous tissue that is continuous with the periodontal ligament and mucosal covering.
This is a welded or removable arm that is used to hook up elastics.
