Tonsil Stone Guide - Symptoms, Causes, & Removal

Tonsil stones (also called tonsilloliths) are an annoying oral health problem, but the good news is they are completely benign. In many cases, the only symptoms are chronic bad breath (halitosis) and occasional throat discomfort. Some people are unaware the problem exists, while others find them a nagging, near constant presence. Prevention and treatment are typically addressed without the need for medical attention, except in severe cases. The best advice from both healthcare professionals and those with tonsil stones is to follow a diligent oral care routine.

What are Tonsil Stones?

They are most common in people ages 20 to 40 and not often seen in children or older adults. Small tonsil stones often remain undetected by an affected individual and are discovered coincidentally during routine dental exams or x-rays. Until recently, this condition was not regularly addressed by oral care providers. The consensus was that tonsil stones were more of an annoying anomaly than an identifiable medical issue. Sufferers were often told the problem was related to food particles in the mouth and throat.

As indicated by their name, tonsil stones form only in people whose tonsils are intact. They are small accumulations of hardened calcium, food debris, mucus, and bacteria. These materials sometimes collect on the tonsils of the soft palate near the roof of the mouth or at the back of the tongue. Most commonly, they form in the tonsil crypts; the concave structures that exist on the surface of the tonsils. Additional anaerobic sulfur compounds are also found in the stones. The presence of these sulfur compounds causes the highly offensive odor associated with the condition. Stones may manifest in clusters or individually. They range in color from white to light brown. A typical stone is about a half millimeter wide and weighs 200 to 300 milligrams, although larger stones have been detected. If you look inside one of these globules, the offensive sensory characteristics are obvious due to the intense, foul aroma they emit.

Causes of Tonsil Stones

Tonsils are two round lumps in the back of the throat. They are similar to lymph nodes or glands in other parts of the body and are a vital part of the lymphatic system. The purpose of tonsils is to trap and prevent airborne particulates and other matter from entering the body. Another function of tonsils is to filter lymph fluid. The tonsils cannot always differentiate between harmful and benign particles and tend to retain tiny bits of matter. The degree of retained matter increases if the amount of lymph fluid is too excessive for the tonsils to effectively filter. Often, this matter settles into crevices in the tonsils.

To date, no universally accepted scientific explanation on the cause of tonsil stones has been published. Current research indicates that there may be an identifiable mechanism at work in the formation of tonsil stones. Experts agree that tonsil stones are a byproduct of the accumulation of various materials (as mentioned above) in the tonsil crypts. These accumulations are associated with the growth of fungi and assorted bacteria. As the structures grow, they become calcified and impervious to antibiotic treatment. Chemical processes called “dentrification” occur in the center. Aerobic respiration affects the surface and acidification occurs at the base.

Symptoms of Tonsil Stones

For those who suffer from tonsil stones, this is a clearly misguided theory. In some cases, it is true that no symptoms exist. However, most people with tonsil stones experience a wide array of symptoms that vary in nature and severity. The most common symptom experienced by a majority of affected people is intense, chronic bad breath. That symptom prompts most individuals to seek professional help, which leads to the discovery of the stones. It is wise to keep in mind that all of the symptoms listed below, although often present in individuals who suffer from tonsil stones, are not definitive diagnostic criteria. If discomfort persists, it is important to see a doctor as soon as possible to identify the underlying cause.

Tonsil Stone Treatment

Removing tonsil stones is not a difficult process. The only permanent solution is removal of the tonsils. This extreme solution should only be considered in cases in which tonsil stones present a persistent, constant, severe state of discomfort and highly offensive bad breath resistant to conservative treatment methods. There are methods that address the immediate problem on a temporary basis and yield satisfactory results. For tonsil stones that are asymptomatic, e.g. do not cause bad breath, no treatment is necessary or recommended.

Home Remedies for Tonsil Stones

The first and most effective treatment is to remove the stone(s). This can usually be done by gargling with mouthwash or salt water to dislodge the stone. It may be necessary to use greater pressure, such as an oral irrigator, to loosen stones from the tonsils so they can be easily removed. If the stone is not dislodged from gargling alone, carefully push up from the bottom of the tonsil with a cotton swab, eye dropper, or finger, thereby forcing it to dislodge from the crypt. Small, surface tonsil stones can sometimes be dislodged by brushing with a toothbrush. For very large stones or stones that create potentially damaging side effects, surgical removal is a viable option. This procedure can be done under local anesthesia at your doctor’s office.

Another potentially effective method is to maintain a diligent oral hygiene routine, including regular cleansing of the tongue. One cause of tonsil stones is thought to be initiated by bacteria living on and under the surface of the tongue. Keeping the mouth, throat, and tongue clean minimizes the amount of mucus and bacteria. It also reduces the potential calcification of these substances, a suspected cause of stone formation. Drinking water and chewing sugar-free gum can help prevent dry mouth. Doing so decreases the proliferation of bacteria in the oral cavity and helps control bad breath. It is important to note that a person must be attentive to oral care on a daily basis in order to reduce the risk of tonsil stone recurrence.
