I had all of, what was left of my severly rotted teeth, surgically removed on the 18th. Today is the 28th and I noticed that my tongue had turned blue then then it has turned green with black on the tip and a little further up. I've not eaten anything or drank anything to cause this. Is there any cause for concern? Should I be worried ?
It certainly warrants a call to your dentist. Obviously something isn't right...
any chance you had a tummy ache and took Pepto- Bismol? That could turn the tongue a dark color.
