After wearing braces, you generally do not need to wear a lifetime retainer, but the specifics need to vary from person to person.
1. Wearing braces mainly serves to straighten the teeth, and in the process of straightening, braces will exert pressure on the teeth so that the teeth will gradually move and return to the correct position, thus achieving the effect of straightening.
2. After the teeth are aligned, the braces are usually removed, but the teeth are not fully stabilized after the braces are just removed, and may shift.
3. In order to avoid the effect of orthodontic treatment being affected, braces usually need to be worn for more than two years after removal, at the beginning, they need to be worn all day long, and after one year, they can be worn only at night. However, there are some people who are older and have serious malocclusion problems, and the chances of rebound are higher, in which case they may need to wear the retainer for the rest of their lives.
After the braces are finished, you need to follow the doctor’s instructions to wear a retainer, specifically how long you need to consult the doctor, you also need to do a good job of oral hygiene, to prevent infection.
