Eeek! I've noticed a hole developing on the front of one of my teeth just above the gumline. I'm completely freaked out by this as I'm 27 and never had anything wrong with my teeth.
Can anyone tell me if they know what this sounds like? I thought tooth decay happened from the inside out? Could it be something else?
Is this kind of thing treatable or do you have to get rid of the tooth?
Thanks!
