The wearing period of braces retainers is usually about 1-2 years, and the exact length of wear varies from patient to patient. Braces work by applying continuous pressure over a period of time to slowly move the teeth in a specific direction. As the teeth move, the bone changes shape in response to the pressure applied, ultimately achieving the treatment effect of correcting malocclusion. For adolescent patients whose skeletal system tissues are still growing and developing, if the periodontal tissues are healthy, braces retainers can be worn for 1 year to achieve a more desirable treatment effect. For adult patients, the wearing period needs to be extended, generally ranging from 1.5 to 2 years. However, some patients with severe periodontal disease or root defects may need to wear braces for a long period of time or for the rest of their lives after receiving the relevant treatment. During the period of wearing braces retainer, you should insist on wearing it under the premise of strictly following the medical advice to better ensure the effect of orthodontic treatment and to avoid the phenomenon of relapse and rebound.
