Some of my posterior maxillary teeth look really off-coloured. I don't remember them being this bad before braces/surgery. I put this down to braces, but I'm no longer so sure. Whitening them seems to have only a temporary effect.
I think I would have been told by my surgeon if any of my roots died. I had X-rays done by my dentist 7 months post op. Surely he would have said something as well. Another surgeon told me that the roots of my teeth are very long... I wonder whether even if the roots may not die due to LF1, but still be traumatised enough to lose their colour.
