I had a big tooth decayed before, but it slowly collapsed after filling, leaving only the root and no crown. How can I insert a tooth?

Disease analysis: hello, according to the symptoms you described, one of the teeth has a residual root, which is generally useless. You can consider taking it out and repairing it after three months. This kind of tooth restoration is mainly to polish the teeth on both sides of the missing tooth, and then make braces on both sides of the teeth to keep the missing tooth restoration. The other tooth has decayed. For such teeth, only by removing the decayed materials and then restoring them with dental materials can the progress of caries be terminated and the health of the teeth be restored. Once the tooth decays to the nerve, the tooth needs treatment.

Suggestion: It is suggested that the dental clinic should be reexamined after three months, and the residual roots should be removed and repaired. For decayed teeth, they can be pulled out or filled.
