I am very concerned about my teeth turning black at the gum line. It also looks like they are eroding in the same area. I have recently been diagnosed with sugar diabetes. I also suffer from major depressive disorder and have Fibromyalgia. Why is this happening to my teeth?
Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have painful gums and teeth are black at cervical region don't worry it can be due to cervical abrasion, or deposition of stains and calculus at cervical region.  For this you should consult dentist and go for Restoration of tooth or if it is stains and calculus then go for Scaling Anderson planning.  Hope this will help you.
