i have really terrible gum disease. this means my gums are receding (6 millimeters in some places) and the bone under the gums are shrinking. i could lose a tooth...and i'm only 33 years old!! I look in the mirror and i can see the gum recession (my front teeth look very long). it's scaring me. I hope that eating no sugar/starches (well, i still eat fruit, and will eat starches if i go out to eat, or on special occasions) will help, because sugar and starches contribute to tooth decay. I think i am more scared of losing a tooth than i am of being overweight.
