Hello, I hope you are well, so here is my problem: I have a greying front tooth following root canal treatment, a few months ago. I have received conflicting information from several dentists when I have asked what to have done about it. Some of them have recommended that I have a veneer, others say I should try internal bleaching, or crown treatment. As it is my front tooth I want to be sure I select the best treatment, I understand that this is a cosmetic treatment so just wondered what you would personally recommend for this problem?
