So, I am 21 years old, and recently, when I've been eating something crunchy, there's a weird feeling in the back of my mouth, like it felt like there was an extra tooth growing in or something. It didn't hurt, it just felt weird. I have no pain whatsoever in my mouth at all, & I've heard that when wisdom teeth grow in, it hurts like he** so I don't know if it's a wisdom tooth or something else. I have attached some pictures, and the tooth in question is the one in the back, behind all the other teeth. And it's only on that one side. I have no dental insurance, and I did have braces for 2 years. If it IS a wisdom tooth, would I have to get it removed even though it's not causing pain?
Thanks for the help!
