I have been having jaw pain for about two days, and pain in a tooth when I put pressure on it. This afternoon and still now, the right half of my lip and chin and halfway back my cheek are tingly/partially numb. I got a filling in the tooth about 6 weeks ago. Saw my dentist today... she says I'm likely to need a root canal in that tooth, but she stated that she did not think the numbness in my face was related to the tooth. I think it MUST be related. I can take prescription strength Ibuprofen for the pain, but what is causing the numbness, and what can I do to make it go away?
