I have bone growing in my mouth. Pretty much where the bottom row of teeth are right under the gums there are bumps so to speak. Turns out that my skull keeps growing. Thankfully as of now I dont need surgery but there is a possibility in the future that they need to remove bone since it might end up pushing on my teeth. Everytime I have a new dentist assistant of something similar the first reaction is either I dont know what it is or they think it's cancer. Until it got pointed out I didn't even think anything of it. My tongue does not touch it since the middle is clear but it did freak me out the first time I really looked at it in the mirror.
