What does a retainer do?
Your retainer is worn once your braces or Invisalign treatment is complete, and it plays the key role of holding your teeth in their beautiful new position to prevent them from ‘relapsing’.
Once active orthodontic treatment is complete, your teeth are susceptible to ‘orthodontic relapse’, or reverting back to their original pre-treatment positions. Your teeth require a period of retention to ensure that they stabilize in the proper alignment.
