I have gum regression. My ex wife was a dental assistant and screamed at me to get a mouth guard. I dragged my feet on it forever because it was $500. I tried an over the counter guard, but would just spit it out in my sleep. I finally caved in a couple of years ago once the regression became enough that I now have tooth sensitivity, and the regression has finally halted. However I’m stuck with what I’ve got, short of doing gum grafting surgery to transplant tissue around the more troublesome spots. It’s not fun or cheap.

Don’t mess around when it comes to your teeth. Floss, brush twice a day, drop bad habits like smoking and excessive soda drinking, and if you grind your teeth, get the damned mouth guard. It only gets more painful and expensive to fix (if even possible) if you ignore it.
