Why Do Retainers Crack or Break?
Learn common reasons retainers crack or break and when it may be time to order a replacement clear retainer.
Retainers can crack or break from normal wear, pressure, grinding, pets, heat, or improper storage. Even a small crack can affect comfort or fit.
Common causes
Clear retainers are thin by design, so they should be handled carefully. Biting them into place, leaving them out of the case, exposing them to heat, or cleaning them too aggressively can shorten their lifespan.
A custom replacement may be the practical next step if your retainer is broken or distorted.
Order a replacement kitShould you keep wearing it?
Do not wear a retainer that has sharp edges, causes pain, or no longer seats correctly. A damaged retainer may not perform as intended.
