Question

Quizplus · Accepted Answer

A retainer is a custom-made appliance that is used to maintain the position of teeth after braces have been removed. It can be either fixed or removable, and is usually worn for several months to a year to ensure that the teeth stay in their new position. The other options listed (activator, tooth positioner, and lingual archwire) are types of braces or orthodontic appliances that are used to move teeth into the correct position, but do not serve the same function as a retainer.
