What should I do if my innermost tooth has a cavity?

Many people pay attention to the state of their mouths, such as the health of their teeth. Some people have a hole in their innermost teeth, and this time they need to consider whether the dental nerve is injured. For different degrees of caries, targeted treatments need to be made, such as some can be repaired through dental restoration, while others require root canal treatment, and then the damaged teeth are extracted.

1. Dental Restoration

A hole in the tooth can be repaired as soon as possible. If clinical examination shows that the hole has not yet damaged the dental nerve and the tooth is not painful, the tooth can be repaired directly, mainly through light-cured composite resin or glass ionomer to restore the shape of the tooth.

2. Root Canal Treatment

Root canal treatment can be chosen for teeth with holes. If the tooth has experienced pain and clinical examination confirms that it has already damaged the dental nerve, root canal treatment is generally required for such teeth. Of course, it is necessary to judge whether the degree of tooth damage still has retention value. If there is no retention value, some teeth can be extracted and then repaired.

3. Tooth Extraction

If necessary, the innermost teeth need to be extracted. If it is a functional tooth, which is the second molar, no matter which one it is, it should be retained, and treatment should be performed as soon as possible to heal the decayed teeth and enable them to perform chewing functions. If the decayed hole has reached the nerve, root canal treatment should also be performed as soon as possible, and post-core restoration should be performed after treatment to restore chewing function. If this tooth is a wisdom tooth, which is commonly known as the eighth tooth, it can be extracted if there is a decayed hole to solve the fundamental problem and prevent the wisdom tooth from continuing to inflame.
