Generally speaking, if the tooth is slightly damaged and the tooth nerve is not involved, then the tooth can be filled at one time. In the process of seeing a doctor, the doctor will first clean up and remove the dental caries, and then fill the teeth with filling materials. If the tooth injury is serious and involves the tooth nerve, then root canal therapy is needed before filling the tooth. This kind of situation needs to see a doctor many times, usually two or three times.
At the first visit, the doctor will make a detailed examination and diagnosis of the teeth and make a treatment plan. If root canal therapy is needed, the doctor will open the pulp and then put drugs to kill the nerve. If root canal therapy is not needed, the doctor will directly remove caries and fill them.
At the second visit, the doctor will make further treatment and fill the teeth according to the treatment after the first visit. If root canal therapy is needed, the doctor will take out the killed nerve and then prepare and treat the root canal. Doctors will fill their teeth with filling materials.
After filling teeth, it is necessary to pay attention to oral hygiene and review regularly to ensure lasting therapeutic effect and oral health.
In a word, the number of dental visits depends on the degree of tooth damage and the choice of treatment methods. Generally speaking, filling a tooth can be done once or twice. If you have specific dental problems or need more information about filling teeth, it is recommended to consult a professional dentist.
