If the tooth is painful because it is embedded and the nerve is not exposed, a filling can be done after removing the decaying material, often using composite resin or glass ionomer, to restore the tooth’s adjacent relationship and prevent the tooth from continuing to be embedded with food, thus avoiding the painful phenomenon. If the tooth is close to exposing the nerve, indirect pulp capping treatment can be done. If the nerve is already leaking, nerve extraction or nerve killing treatment can be done, and after the nerve killing, pulp drying will be done. If the nerve is removed, it can be done under anesthesia to relieve the pain. After the nerve is removed, the tooth is usually restored with a porcelain crown or an inlay to ensure the stability and long-term use of the tooth. If you don’t have porcelain teeth after the treatment, the teeth are especially prone to splitting or falling down piece by piece after many years, which can easily cause tooth loss, and after the tooth loss, you need to have a dental implant, or grinding down the front and back teeth to be able to repair, the loss is relatively large, so it is recommended to have timely treatment when worm teeth occur.
