If you struggle with bad breath, maybe you should check your tonsils and see if there are any white or yellow spots on them.
Tonsil stones, also known as tonsilloliths, are made of bits of food, bacteria, or minerals such as calcium which get stuck in the folds and gaps of the tonsils. These stones or lumps have a cheese-like structure.
Except for bad breath and sometimes discomfort in the throat, these stones cause minimal symptoms.
