I had a root canal done on two teeth. Both teeth are top molars ( one on each side of mouth). The specialist did the root canal back in Oct. . My teeth throb after I eat ! When I push on the tooth it relieves the throbbing! The specialist can not find anything wrong with the tooth! The same thing is going on with the tooth that my dentist did the root canal on! No one knows what is going on. The throbbing gets so bad at times that i have to take pain meds! HELP!! :)
