A clear plastic retainer is a custom-formed thermoplastic appliance that holds teeth in their planned positions after orthodontic movement.
What does a clear plastic retainer do after orthodontic treatment?
A clear plastic retainer is a custom-formed thermoplastic appliance that holds teeth in their planned positions after orthodontic movement.
How does a clear retainer help hold teeth in position?
The retainer fits over the crowns and applies gentle restraint while the periodontal ligament and bone adapt. It differs from an active aligner because its job is retention, not programmed tooth movement.
How should you wear and clean a clear plastic retainer?
Wear it according to the orthodontic plan, remove it for foods unless instructed otherwise, and clean it with cool water and a soft brush. Store it away from heat and do not force it over a shifted tooth.
When does a damaged or painful retainer need attention?
Contact the orthodontic team if it cracks, warps, becomes painful, no longer seats, or is lost. A delay after tooth movement can make replacement more difficult.
What should you ask about wearing and replacing your retainer?
Ask how long and how often it should be worn, how to clean the material, when it should be replaced, and what to do if it no longer fits.
