I saw your post from awhile back and was hoping you could tell me if the staining on your teeth ever went away. I was on minocycline for only 7 weeks and I have a blue/gray discoloration on my teeth just as you described. lower top and upper bottom third. It isn't too dark but in certain light it looks worse. I am 41 years old and am devastated. I just started bleaching but so far it isn't helping. Please let me know if it went away or if there is anything you were able to do to resolve it.
Thank you so much.
Sandra
