Whitish cheesy materials collect in the crypts and pits of tonsils due to food particles, debris , exudates etc. It may lead to formation of stones (tonsilloliths) if present for long by deposition of calcium. It is harmless if not causing any reaction or infection. May be extruded with little pressure of brush or finger. If there is problem of recurrent infection, foul breath, foul taste etc, then tonsils maybe removed.
