A large hole in a back tooth requires active medical examination. Depending on whether the nerve is involved and the amount of remaining tooth tissue, the choice will be whether to fill the tooth, root canal treatment or extraction.
1. If the hole in the posterior socket is shallow, the nerve has not yet been violated, and the tooth has a good retention pattern, then filling treatment can be carried out directly, which is also commonly known as filling, and the main steps are: cavity preparation, cavity disinfection, application of adhesive, and filling of the cavity.
2. If the cavity of the posterior alveolar tooth is deeper and has violated the nerve of the tooth, and the remaining tooth tissue still has the value of preservation, it is necessary to carry out root canal treatment, which is often referred to as killing the nerve, and the main steps are: root canal preparation, root canal disinfection, root canal filling, and crown restoration at the earliest possible time after the treatment.
3. If the hole of the back tooth is very deep, and the remaining tooth tissue has no retention value, it is necessary to directly extract the affected tooth, and actively carry out implant restoration after extraction.
