<s>[INST] I have a dead tooth in my mouth and afraid to go to the dentist. It is in the left lower part of my mouth and it is shaky. I have been rinsing it with listerine and trying to make up my mind to go to the dentist. I had it for couple of years. What do i do. [/INST] Thanks for your query, I have gone through your query. The mobile, dead tooth can be treated with root canal treatment and scaling and root planing with bone graft. If there is sufficient tooth structure left out(about 50-60%) and if sufficient bone support is there, then you can go for the above said treatments. If there is no sufficient bone or tooth structure, then you have to get the tooth removed under local anesthesia. Nothing to be panic to consult a dental surgeon, it's a simple procedure, make up your mind and get the treatment done. Otherwise, it might get infected and results in swelling and limited mouth opening. I hope my answer will help you, take care. </s>
