Otherwise relapse. Time: Wear for at least one and a half to two years. Adults even need to wear it for life. Wearing 1.In the beginning, you should wear it all the time except for brushing your teeth and eating. 2.After three months or six months, you should only wear it at night as prescribed by your doctor. 3.When you first put it on, you will feel uncomfortable and even affect your speech, but it will return to normal within a few days. 4.If there is a fixed pressure point, and it does not disappear in 3-4 days, you need to review the retainer for adjustment. 5.Please do not lick the retainer with your tongue. Otherwise, it will affect the teeth.
