My tonsil are fibrotic and dead epithelial cells and food traping forming yellow appearance ? what to do

Tonsil stones: Tonsilloliths are calcified material lodged in the crypts of the tonsils. Gargling with warm salty water each morning and drinking carbonated beverages may help dislodge tonsil stones.

Tales from the crypt: Sounds like you have deep pockets in your tonsils that collect debris and food-- and part of the nails you've chewed-off thinking about this. And I bet your breath may get, how you say, "interesting" at times. Well, best to get examined by a throat specialist (ENT). In the meantime, rinse/gargle thoroughly, chew gum and wear a steel-plated surgical mask with a one-way valve.
