Hi, I had root canal a year or so ago, and my tooth has been discoloured. I have had internal whitening which has lightened the overall colour of the tooth, however I have 3 very distributive black lines on my tooth and my dentist says there is nothing else he can do. But he is thinking from a dental perspective not a cosmetic, as to me my tooth is still discoloured and makes me very self conscious as it’s my front tooth. Does this sound like something that can be sorted?
Thank you.
