Whether caries in the neck of the tooth can be resolved in a single visit to the oral health care provider. This question is uncertain and depends on the depth of caries in the neck of the tooth. If the caries in the cervical region is relatively shallow, it is usually possible to treat it in one visit to the hospital by removing the decay in a turbo-rotor and filling it with dental filling materials. However, if the caries in the neck of the tooth is relatively deep, there are already obvious symptoms of pulpitis. In most cases, it is unlikely that the problem can be solved in one visit. In most cases, root canal treatment of the pulp is required. This is relatively more invasive and time-consuming, and generally involves the use of a turbine drill to open the pulp from the symphysis of the tooth, remove the pulp while removing the decay in the neck of the tooth, perform root canal treatment, and finally repair the tooth. And for this root canal treated tooth, we generally recommend the application of a crown restoration to protect the crown to avoid the risk of splitting the tooth, which takes longer to make.
