How to Repair a Dental Retainer

Updated July 19, 2017

Consult your orthodontist to repair a damaged dental retainer. Lab technicians can repair cracks or warping. Quick do-it-yourself fixes with household adhesives do not create permanent solutions. In any case, household glue contains harmful chemicals that should not come near your mouth. Depending on the severity of the damage, it may cost you more than £65 to replace your retainer, so taking good care of it is the best way to avoid repairs.

  1. Check your retainer often for signs of cracking. If you discover the damage early, you will have a better chance of getting away with a low-cost repair.

  2. Consult your orthodontist if your retainer causes pain or discomfort. This is a sign of a poor fit in your mouth, and an orthodontist can make a more accurate mould. Not only will you feel better, but it also will prevent strain and damage to the retainer.

  3. Schedule an appointment with your orthodontist as soon as possible. The damaged retainer prevents proper care for your mouth.

  4. Brush your retainer every time you brush your teeth. Preventing plaque and bacteria build-up can help prevent damage to your mouth and the retainer. Use a non-abrasive toothpaste to prevent scratching the retainer (this is especially important with plastic retainers).

  5. Soak your retainer in a denture cleanser at least once a week. Mix the cleanser with a cup of warm (not hot) water, and always rinse the retainer with water before sliding it back in your mouth.

  6. Store your retainer in an orthodontist-approved, plastic case. A sturdy case allows a large amount of leeway with your retainer, supplying reliable protection from everyday accidents such as dropping or stepping on your retainer.

  7. Ask your orthodontist for any other specific care instructions. Different types of retainers require different safety measures. You should understand all aspects of your retainer.

  8. Tip

    Find an attractive retainer case that you do not mind taking with you everywhere you go.


    Avoid subjecting your retainer to intense heat such as hot water or direct sunlight; heat will warp it.
