Hello and thanks for your question. What you are describing are tonsil stones, also called tonsiliths or tonsilloliths. They are fairly common and can cause problems with pain and bad breath. They occur when the tonsils develop crypts, food packs in the crypts then spoils and makes the little white balls of bacteria and spoiled food. Here is a website to give you more information http://www.webmd.com/oral-health/guide/tonsil-stones-tonsilloliths-treatment-and-prevention If the tonsil stones are very problematic ENT doctors can use surgery or laser treatments to smooth out the tonsils and remove the cypts.
