I have some tori that won't stop growing (a little one on the roof of my mouth [it doesn't bother me though], a BIG one on each sides of my mouth, and two big ones in the middle [where my tongue is]). Since about last month, the ones in the middle connected together, and are now about 3x the size of what they were last year. My orthodontist and dentist both said it was the biggest they've seen yet. I'm only 17, so chances are they're going to grow for another while.
