Today there are more orthodontic devices than ever before, allowing more choices in how braces look and how long the patient must wear them. A better bite and fewer jaw problems are often the byproducts of what begins as a cosmetic procedure. The top front teeth extend over the lower front teeth slightly, while the molars line up and meet on both sides of the mouth, top and bottom. The teeth are straight and not crowded, spaced close together like a string of pearls. But in most mouths, variations on this theme are more common.
Some problems affect chewing or speaking, but most are simply cosmetic issues.
Improper tooth alignment is called malocclusion. Malocclusion is not a disease, but crooked teeth can decay faster than straight ones because people have more trouble keeping them clean. Severe misalignments may require extra flossing and brushing. But malocclusion doesn't always cause jaw problems or pain, and many people have lived long and healthy lives with misaligned teeth. Nevertheless, malocclusions can be embarrassing.
