Doctor Answers (2) on Dental braces
The time duration is obviously around 8 months to 1.5-2 years depending upon the case, once the braces r removed, you have to wear retainers to keep the moved teeth in place. Duration of wearing retainer also depends upon the case.
For the proper knowledge of that, you should ask it your dentist who is giving treatment. He can very well explain about the wearing time duration of retainer in your case.
Relapsing depends upon the efficiency n knowledge of the orthodontist from whom you are taking treatment, your Oral hygiene status, perio condition ( condition of your gums n bone holding the teeth) , Nutritional conditions of your body and upon the instructions given to you by your dentist.
this is ortho treatment , which takes time and after treatment you have to wear retainer for at least 6month to 1 year
and yes some times relapse does happen depending upon ability and efficiency of your dentist,
