Very simple: Your skin is living tissue.. It has cells that can divide and repair damage, like a cut. The enamel and dentin of your tooth is not alive... There are no cells to divide and repair the damage. Only the nerve in the center of the tooth is alive, and if it is traumatized too much, it dies. Your enamel is comprised of an inorganic matrix of calcium and other materials.

Blood Supply: Cuts are healed by new cells growing over a wound . Once a tooth is formed it does not change on the outside of the tooth. A cavity is the erosion of a part of a tooth, that has no blood supply or the tooth cells to grow new parts of the tooth. So once a cavity has reach a certain size it can not be reversed, it must be removed. Then a filling can replace the destroyed parts.

Possibly: It can be either a lost restoration, decay, or an open contact on the new filling. Consult your dentist to diagnose the problem.

Decay: Go to your dentist and get it taken care of immediately. Sounds like root canal if it can be saved.
