Thanks for your assistance. I've had a cap on a tooth for long time. It's gone dark and looks as though it may be dead. Now the gums are receding a past the line of the cap a little revealing the dark, possibly dead, tooth underneath.
So I'm wondering what should be my considerations and options for this tooth be? Also there is no feeling or any pain, so it's not an emergency though I'm becoming more concerned about the aesthetic since you can start to see the tooth underneath.
thank so much,
