Methods of dental nerve restoration include root canal treatment and pulp cutting, etc. Which one is the best depends mainly on the patient’s specific situation. 1. Root canal treatment: If the nerve pain has already invaded the pulp, causing infection or necrosis of the pulp, it is necessary to remove the decayed part of the tooth and clean the pulp, so as to sterilize the root canal, and finally fill it with special materials, so as to make the root canal in a sterile state, but the tooth may be more fragile after the root canal treatment. 2. Pulpotomy: It is mainly a transitional treatment for underdeveloped teeth, which generally involves removing the crown pulp, preserving the root pulp and performing root canal treatment after the tooth is fully developed. There are other methods of dental nerve restoration. If there is any abnormality of the dental nerve, you should seek medical treatment in time.
