Wearing braces at the age of 30 generally has a role to play. 1. Orthodontics does not have a strict age limit, generally around 30 years old can also be orthodontic, wearing braces can also correct malocclusion, so that the teeth are more straight, but in orthodontics must choose a regular hospital, so that you can achieve better results. 2. If an individual’s teeth are not in the right position or direction and malocclusion occurs, orthodontic treatment can be carried out at any time, and the age of 30 generally does not affect the effect of orthodontic treatment, as long as one’s own periodontal condition allows orthodontic treatment. There is no strict age limit for orthodontic treatment, so there is no need to have too much psychological pressure. After orthodontic treatment, you need to pay attention to personal hygiene and regular review.
