<s>[INST] I seem to be getting past from one dentist to another. I have had root cannal treatment  and crown and 3 crowns and ever since I feel as I have been smacked in the face.  I also have numbness in my face and some times ringing and deafness.  Surley this must all be related.  I did not have any of these problems befor I started doing any dentist work.  what is the solution? [/INST] Hello and welcome to Chat Doctor, Numbness may be due to facial nerve damage during local anesthesia administration. Ringing and deafness may be associated with improperly placed or high points in the crown placed, Also get the root canal treated teeth examined. An x-ray of the treated teeth will help to evaluate the condition.Through scaling is to be done. Maintain oral hygiene well. Re-rct can be done if required. High points in crown has to be corrected soon to prevent temporomandibular joint disorders. Take care. </s>
