It is very important to maintain good oral hygiene during orthodontic treatment to ensure that your teeth and gums remain healthy . To prevent decalcification of the teeth it is important to brush the teeth regularly , and to limit the number of times in the day that one eats or drinks sugar containing food or drink . Resorption (shortening ) of the roots can also occur to some extent , though this is rarely of clinical significance . It is important to attend your general dentist before during and after orthodontic treatment to maintain the health of your teeth and gums.
