Hello- I am 42 years old and on disability, so I don't have "extra" money to spend at the dentist's office. To begin with, I have a rare "jaw" condition that prohibits me from being able to open my mouth more than an inch or less (measured from bottom of the top teeth and the top of the bottom teeth). Keeping it open for anything longer than 20-30 seconds gets real painful, so you can imagine what a visit to the dentist's office does to me! Anyway, I've had some recent discomfort in the bottom left portion of my mouth, behind the last bottom molar, but on the inside of the gum, where the side of my tongue meets the gum. I can feel this protrusion with my tongue. When I looked in the mirror, I found what looks like a wisdom tooth pushing through the gum. So far, the amount of "tooth" exposed is about the size of an average head of a nail. Is it probable that this is a wisdom tooth at 42 years of age? My other wisdom teeth came in when I was in my thirties, but I thought that I was finished with them! I would greatly appreciate any thoughts you might have about this. Thanks!
