After you open the first-aid kit, you pull out the bandage wrap, and the healing spray, so the tooth cut doesn't get injected, you suddenly see it heal up quickly as you saw that nothing was left on there, but literal skin. You place the bandages back in the first-aid kit, and closed it after seeing what just happened.
Just then you feel your teeth fall off one at a time as if you skipped out on brushing your teeth before you came out into open water. However, just when you think you'd be spending the rest of your life eating smooth food, you felt new teeth grow in their place. Each tooth you felt grow was sharper than the original, and were the same shape as you feel them come out of your mouth. Not only that, but you felt your neck stretch out as you feel more rows teeth sprout from behind your first row.
