Orthodontic treatment for adults can begin at any age, and there is no upper age limit for wearing braces. However, it is important to note that treatment won't start unless you have a good level of oral hygiene, as orthodontic treatment can increase the risk of tooth decay and gum problems. In the UK, orthodontic treatment is available in the NHS for young people under 18 at no cost, if a dentist feels they need it. If you are older, treatment time with braces may take longer than if you were a child.
This is because when the jaw and the bite continue to grow and change shape and position, the teeth and the drill bit are more easily guided to a better position. Children's mouths are also more malleable, so their teeth move a little faster than those of adults. Some orthodontists work with orthodontic therapists who can adjust orthodontic appliances under the supervision of the orthodontist. This means that even if you are an adult, you can still benefit from orthodontic treatment.
