I recently saw my dentist for tooth sensitivity . He applied a liquid material that he brushed over 2 molars and one wisdom tooth. It was applied up near the gums. The sensivity was lessoned yet I soon developed issues with my tmj joint. Although I always experienced cracking in my jaw I never experienced pain and tightness  like I am now. My question is can I be having an alergic reaction to the material the dentist used on my teeth?

I have the worst pain on the right side of my mouth.  It feels like contractions in my mouth.  The pain shoots through my mouth, then it starts to throb and stops.  A few minutes later it stops then starts all over again.  My dentist prescribed antibiotics and pain med, the pain med doesn't help
