I've been going to the dentist for a couple of months done. He got done a couple root canals. Everything ok. He did cleaning. Everything ok. Then he said he wants to do deep cleaning because there is something wrong with my gums so he started with bottom right. I came home and had headaches on the right side of my temple for a week. The teeth also hurt. He recommended I take ibuprofen 800. I did it went away. Next week I did the top right cleaning. Same thing tooth aches and headaches on my right side of the temple. He did radiography and said there is nothing wrong and these might be healing pains. I kept taking ibuprofen 800 once a day sometime twice. Last week I went and did the deep cleaning on top left side. Now I got headaches on both sides of the temples as well as my teeth hurt in weird way. Not like a tooth ache but more of a annoying way. I decided to do an experiment. I did not eat anything for one day. No pains at all. The moment I eat in the evening the pain came back within minutes. So for some reason I am super sensitive and every time I use my teeth now not only I get tooth aches but this incredible pain in my temples on both side of my head. I'm suppose to go next week to do the bottom left side for deep cleaning and it's been almost a month now and the pains still come every time I eat. What should I do? Is the sensitivity ever going to go away? I never had this before.
