question: Hi, recently I had my teeth (cracked cavaties) fixed and I thought this would fix the problem where if I ate sometime with citrus (lemon) it would actually feel tingely and annoying to my tooth and then the side of my face would swell up slightly.  It would only last  until the feelings in my tooth and then would go away.  It s been doing this for some time.  Should I go back to the dentist?
