Popular types of invisible braces include ceramic brackets, inside braces and clear aligners. Ceramic braces are just like metal braces, except that they use tooth-colored brackets (and sometimes tooth-colored wires) rather than metal to straighten teeth.
Braces have three basic parts: 1) Brackets â brackets that are attached to each tooth. 2) Bonding or band â the material that attaches the bracket to the tooth. 3) Arch Wire â a thin metal wire that runs from bracket to bracket. Braces have come a long way from the âtrain trackâ look of years ago. Today, many orthodontic patients can get braces that attach to the backs of the teeth, or use transparent brackets.
