There are several reasons why someone should consider getting braces. For example, children may need them in order to correct early dental issues, such as a cleft palate, while younger and older people alike may use braces to help straighten teeth that have begun to grow crookedly or to correct an overbite or underbite.
For children who could benefit from wearing braces, 9 to 11 years old is the recommended age to begin. This is the time at which the adult teeth have mainly set in, but before any serious problems can develop that may hinder the straightening of teeth in the future. However, exceptions may occur in cases where children need braces for their primary teeth or before any teeth set in at all (such as the case of a cleft palate).
Adults who consider getting braces later in life may need them in order to preserve teeth that have begun to get worn down. Preserving teeth is essential for overall health, as healthy teeth are tied to infection prevention and healthy eating. Furthermore, adults may want to get braces for the same reason as kids; to correct crooked teeth or improve the quality of their smile.
