3D-printed toothbrush cleans teeth in six seconds

The video tutorial explains the process of creating a dental impression using a technique similar to molding braces. It describes how a 3D printer is used to produce a customized mouth guard based on the mold. The mouth guard features 400 bristles set at a 45-degree angle, allowing users to clean hard-to-reach areas by biting and grinding. Additionally, the device includes a handle that doubles as a floss dispenser and a built-in tongue scraper, enhancing dental hygiene.
