Mouth and teeth problem
Doctor Answers (2) on Mouth and teeth problem
These particles may be either food debris or tonsil stones. This is more common in people with tonsillitis ( inflammation of tonsil ).
You can avoid it by brushing twice a day ( especially during night as the saliva flow is less during night, hence causing more accumulation of debris) & by doing warm saline rinses ( add a pinch of salt in Luke warm water).
Also get your tonsils checked.
Wishing you a speedy recovery.
