Yup. I used to always, even in my sleep, have a mint in my jaw between my lip and bottom teeth. After too long of that it literally rotted my bottom canine tooth and a couple of the surrounding teeth. Now the nerves are exposed and naturally as an emetophobe I won't go to the dentist for fear of someone touching the inside of my mouth. I love mints but they started to give me hell, so now I have to rely on just peppermint oil
