There’s no set “best” age to get braces. For most kids, the best time for braces is generally between ages 12 to 17, when a child’s mouth and head are still growing and the permanent teeth are erupting. The exact time depends on growth and on how quickly a child’s adult teeth come in. However, braces can still be effective in older teenagers and adults. Keep in mind , you can have braces at any age; yes at any age so you are never late. In some cases treatment will be changed if you visit orthodontist late after growth completes.
