<human>: I had a tooth ache a few times for which I suspected I was grinding my teeth.  While the area does not hurt, not sensitive to touch or hot/cold, I now have the sensation in my lower right cheek adjacent to that tooth that appears may be slightly swollen, but the sensation is that of wearing off Novocaine.
<bot>: Thanks for posting your query to Chat Doctor. I have gone through your history. You should visit a dentist for complete oral and radiological examination of the concerned tooth as due to tooth pain history you might need a root canal treatment. Till then, you can do warm saline rinses 3-4 times a day and take a painkiller like Coquitlam for mild pain or Retool DT for severe pain 2 times a day. Hope my answer will help you.
