Teeth Whitening for Grey Tooth from Injury?
My top incisors have turned grey due to falling last summer and then slamming into the sidewalk. X-rays said I didn't need a root canal, (I've had no pain nor sensitivity) but I don't know what I can do about them being grey. Will Teeth whitening work and last or do I need to do something more permanent? The rest of my teeth are very white which makes this very obvious.
