Well, a couple of weeks ago saw an endodentist - found that I have TWO root or nerve canals in a tooth that should only have one!! The canals were totally parallel to each other thus they didn't show up in an xray and only visible with the microscope!! Massive infection in canal number2 - all cleaned, pain killers and antibiotics - still good..fingers crossed
Your symptoms are indicative of hyperocclusion, or a heavy bite. This can be easily fixed with an occlusal adjustment. Antibiotics will not help, if that was your dentist's only solution, you should get a second opinion.
Seeing an endodontist to evaluate the affected tooth is advised.
