83. Selfrepair

tooth is the only part of the human body that can’t repair itself. If you’ve ever chipped a tooth you know just how sadly true this one is. The outer layer of the tooth is enamel which is not a living tissue. Since it’s not alive, it can’t repair itself, leaving your dentist to do the work instead.
