Surface of Dental Plastic Should be Cleaned

If plastic residual shards have fallen off during the filing process, carefully wash the broken surface of the dental plastic with a toothbrush.

Adhere the edges with DENTAL GLUE.

Ensure that the acrylic bonding, waterproof, plastic, or dental glue you choose is not toxic, since it will be placed in the mouth. Follow the instructions carefully to determine how much glue is needed and how long it will take to dry. Check whether the broken pieces of the plastic retainer fit well together by putting them together. To reattach the pieces, apply glue only to one side of the broken retainer and push them together gently.

After the Retainer has Dried, Scrape off Any Excess Glue and Wash it

Let the glue dry for the time indicated on the glue label by holding the two pieces together. Scrape off any excess glue from the retainer and file any raised spots or ridges once the pieces are perfectly adhered and the glue has dried. In order to avoid bacteria or germs entering the mouth, wash the retainers thoroughly after scraping off the excess glue. A toothbrush can be used to clean it carefully.

Test the Usability of the Retainer

You can now try your retainer in your mouth to see if it sets properly after it has been fixed. Any uncomfortable edges should be filed off if they don’t feel right. After the crack has been repaired, the retainer should function normally. Your dentist should be consulted if it doesn’t.
