Age limits for braces can vary, but they are typically recommended for children and teenagers, with treatment often starting between the ages of 9 and 14 when the permanent teeth are coming in. However, there is no upper age limit for orthodontic treatment, and many adults also get braces to improve their dental health and appearance. The suitability for braces depends on an individual's dental needs, and it's best to consult with an orthodontist to determine the most appropriate age for treatment.
