I have a fractured tooth. It is a free standing fracture from the cuspid to the base on a bottom back molar. I have some wax bars from my hives-very nice wax refined a number of times. I shaved a little wax off and placed it between the main tooth and the free standing fracture and pressed firmly-instant relief.
I should also say that just because I did this does not mean that you should. I will see a dentist.
