Can you still correct your teeth at the age of 40?

Orthodontic treatment is generally possible at age 40, provided that periodontal health is good and there are no severe underlying medical conditions. With an appropriate orthodontic approach, dental alignment issues can be effectively improved. If needed, it is recommended to seek timely medical consultation and follow professional guidance for treatment.

Although teeth and jawbones in individuals around age 40 have fully matured, this does not constitute a contraindication for orthodontic correction. If examinations show no significant periodontal inflammation, sufficient alveolar bone volume, and no uncontrolled systemic diseases such as diabetes or heart disease that may impair healing, the individual is likely a suitable candidate for orthodontics. Teeth can still gradually shift under professional guidance to achieve improved alignment.

Based on individual dental conditions, suitable orthodontic options can be selected. For example, clear aligners offer aesthetic advantages and are easy to clean, making them ideal for those concerned about appearance; traditional metal braces are cost-effective and well-suited for more pronounced dental misalignments. Although treatment duration may be slightly longer than in adolescents (typically 2–3 years), satisfactory results can still be achieved with proper care.

Daily oral hygiene should include using interdental brushes designed for orthodontic appliances to clean the spaces between teeth and braces. Clear aligners should be soaked weekly in cleaning tablets specifically made for aligner maintenance to ensure cleanliness. Hard foods such as nuts and hard candies should be avoided to prevent damage to the appliances.
