Question: what does it mean if you have white things in the back of your throat?
Answer: Tonsil stones, or tonsilloliths, are hard, sometimes painful bits of bacteria and debris that get stuck in nooks on your tonsils. Your tonsils are gland-like structures in the back of your throat. You have one on each side. Tonsils are made of tissue with lymphocytes, cells that prevent and fight infections.
