After braces are removed, most patients will need to wear a retainer all the time for the first six months, then only during sleep for many years.he time required for braces varies from person to person, depending on the severity of the problem; the amount of room available; the distance the teeth must travel; the health of the teeth, gums, and supporting bone; and how closely the patient follows instructions.
Do I have to Wear Them All the Time? Your orthodontist will prescribe the retention plan that is best for you. Some retainers are used full-time for the first 6 months; after that, the retainers are worn only at night, for a few years. Other retainers are worn full-time for about a week, and solely at night thereafter.Fixed retainers are normally kept in place for 5 years.f you have a fixed retainer, you should spend more time to brush the back of your teeth. You have to brush all around the wire so that calculus will not form. You will be instructed on how to use dental floss with a floss-threader. Do remember not to use your front teeth to for biting hard foods or objects.
