If a small piece of tooth is broken, it is recommended to take the broken piece of tooth to the dentistry department as soon as possible if the tooth can be found, and the small piece of tooth can be glued on by bonding material, which is sometimes a relatively good repair method, but the specific situation needs to be analyzed. If the broken tooth cannot be found, resin restoration can be used to restore the shape of the tooth, but it should be noted that if the broken part is a stress concentration area of the bite, the restored tooth may be fractured. Ultimately, the best solution is to do crown restoration, which is usually called porcelain crown or all-porcelain crown, but it needs to grind away more dental tissue, and it is recommended to go to the dental department as soon as possible to check, ask and choose the applicable plan.
