Hi Anita

I can relate to this (just for something different!!!)

Before radiotherapy I had 2 wisdom teeth and one upper crown tooth removed. Following radiotherapy, the space where the crown tooth was taken from closed over, my jaw had contracted. On the upper left side (where most of the radiotherapy was aimed) I have also had 2 teeth move from being straight to bending inwards.

My upper natural teeth haven't discolored. I get them cleaned every 2 months at the dental hygenist. The flouride might be the cause. Is Clark using a mouthwash, because several mouthwashes can cause teeth to discolor.

Take care

Karen
