A dental retainer is an orthodontic device used to keep the teeth in place after you have removed your dental braces. They can be removable or fixed. After your braces are removed, it takes about a year for the ligaments around your teeth to get hard so that new position of your teeth can remain fixed. If you don’t use retainer, then the teeth can go back to their original position which is medically known as ‘orthodontic relapse’.

Indications of Retainers

  • After braces: After removal of your braces, its absolutely necessary that you should get your retainer because there are very high chances of orthodontic relapse especially in children because they have growing teeth and jaws but they are recommended for every person irrespective of age.
  • For minor malocclusion: Dental retainers can also be used to correct some minor malocclusions for which you don’t require prior fixation of dental braces.
  • Tongue thrust: A condition where your tongue comes out in between your upper and lower teeth while speaking. Special retainers known as tongue cage retainers are beneficial as it prevents the tongue from going forward when you speak
  • Bruxism: It comes under temporomandibular disorders. Bruxism means grinding of teeth at night because teeth are not able to meet properly when mouth is closed. Special retainers help these people by preventing the contact of teeth, thus grinding is avoided.
