If you have bad breath and the uncontrollable urge to clear your throat, you may have tonsil stones. However, tonsil stones are not a sign of poor hygiene nor poor oral health practices. Tonsil stones are hardened white or yellow globules that form inside pockets/crevices (crypts) on the surface of the tonsils, located in the back of the mouth directly behind your lower molars or wisdom teeth. Occasionally, these calcified deposits accumulate on the roof of the mouth and in the back of the throat, although they are more typically found in the tonsils.
So you are likely wondering what causes tonsil stones. The simple answer is bacteria, but several compounding factors lead to their formation. The primary cause is accumulations of bacteria, fungus, dead cells, food particles, and mucus collecting in the tiny crevices dotting the surface of the tonsils. Tonsil stones do not appear suddenly, but grow gradually in the crevices, in much the same way as pearls form inside oysters. Because tonsil stones develop within these pockets, they are often not discovered until their presence is detected on radiological scans.
Some experts believe that in specific cases, the location of tonsil stones plays a more important role than unchecked mouth debris. For example, when they are located around the tonsils in the peritonsillar area, this leads to tissue growth in abnormal areas (ectopic tissue) and calcifications.
As a result of sitting undisturbed within these almost microscopic pockets, the debris hardens and calcifies into tiny white or yellow stone-like pieces. Tonsil stones contain magnesium and calcium salts such as oxalates, ammonium radicals, and hydroxyapatite. The stones are usually no bigger than two millimeters in thickness and often cause extremely bad breath as the primary symptom.
The role and function of the tonsils
In prehistoric times, tonsils performed vital immunological functions, filtering out various harmful viruses and bacteria from the air before they reached the lungs. Evolution has led to modern-day tonsils that are inundated with 20 times more germs and far more diverse bacteria than what existed in our prehistoric ancestors.
As a result, many individuals who still have tonsils frequently experience inflamed tonsils or tonsillitis and the inability to cope with a multitude of bacteria and viruses infecting the air. When tonsils are swollen, the adenoids are also frequently swollen. Adenoids or pharyngeal tonsils are located in the area between the throat and the back of the nose and filter out bacteria in much the same way as tonsils. Tonsil-related illnesses are a common underlying cause of tonsil stone formation.
- Bright red, inflamed tonsils or tonsils coated with a yellowish film
- Sore throat
- Swollen lymph nodes
- Fever and earache
- Bad breath (halitosis)
Why do Tonsil Stones Cause Bad Breath?
Tonsil stones cause bad breath (halitosis) because anaerobic bacteria flourish in low-oxygen conditions, such as the environment found in and around tonsil crevices. Anaerobic bacteria continuously excrete potent amounts of substances that smell like rotting eggs. Individuals suffering from tonsil stones are especially aware of this odor when a tonsil stone disintegrates, is dislodged, or inadvertently chewed.
If a person has dry mouth, this makes the situation worse because without adequate saliva, which contains oxygen and antibacterial qualities, the bacteria grow unchecked. Lack of sufficient saliva combined with food and mucous debris directly contributes to tonsil stone formation and bad breath. For more on this subject, click here.
