What if you see a black tissue at the place where the tonsil was sitting? If you see this black tissue then it can be necrotic tissue, and it’s dead tissue as a result of the tonsil stone bacteria and toxins. When you remove tonsil stones and see this black spot you should take in contact with your doctor. This is because at some times the body needs a little help with removing it. Basically the cells die in order to prevent toxins, bacteria, or viruses from spreading to nearby cells. It’s sort of a self destruct option and the cells have started to decompose. You can see this effect on many spider bites. The area becomes black because the cells is trying to protect nearby cells.
