Q.
Hi Dr. Moore, I have had to replace a crown on my front tooth 4 times in the last 1.5 years because the crown will not adhere to what’s left of my tooth. Secondly, each time the crown falls out, my tooth and the post is completely black – almost charcoal black in colour. My dentist does not know what is going on, says he has tried different cements and has used a steel post, and therefore believes that there must be a crack in my tooth causing saliva to get in and erode the post. He believes the next step for me is an implant to ensure he can attach a crown more permanently? Can you please advise if you have heard anything like this or if you would like me to send a picture for you to see? My dentist, and the other dentists in his office have never seen a tooth (that has had a root canal done years ago) turn black and yet still be solid. PLEASE help….should I be seeing a specialist? Any references you can provide in Toronto Canada? Thanks in advance and I hope to hear from you.
