Understanding Bothersome Tonsil Stones: Causes, Symptoms and Treatment Options

Understanding Tonsil Stones

Tonsil stones, also known as tonsilloliths or tonsil calculi, are accumulations of debris and bacteria that form in the crypts and crevices of the tonsils. Although they only occur in about 5-10% of the population, they can cause discomfort when they become dislodged and the symptoms can be confused with other throat issues.

What Causes Tonsil Stones?

Tonsil stones develop when the following conditions are present:

• Buildup of bacteria and debris in the tonsil crevices and pockets
• An abundance of postnasal drip, which helps to push debris into the tonsil pockets
• Inflammation or repeated bouts of tonsillitis, which can fill the pockets with white blood cells and cell debris

The debris consists of food particles, mucus, dead cells, saliva and bacterial colonies. Over time, these materials consolidate into white or yellow soft masses that take on a calcified outer layer. They can be as small as a peppercorn or can grow substantially larger over time.

Common Locations and Size of Tonsil Stones

Tonsil stones typically form in the crevasses of the palatine tonsils, which are located on each side at the back of the throat. However, they can occasionally form in other hidden regions like:

• The rear areas of the tongue
• The walls of the throat
• Around the adenoids
• Underneath the skin of the tonsils

The size of tonsil stones varies greatly, with dimensions ranging from:

• As small as a tiny seed
• As large as a whole pea
• Larger stones the size of a peppercorn
• Some can reach 1 cm to 1 inch across

Common Symptoms of Tonsil Stones

Only about 20% of people with tonsil stones experience problematic symptoms. However, when present, common complaints include:

Bad Breath

Foul-smelling breath is a classic sign of tonsil stones. The bacteria and rotting debris trapped in the pockets and crevices produce hydrogen sulfide and methyl mercaptan gases that give breath an unpleasant "rotten egg" odor.

Visible White Spots

In some cases, the hardened tonsil stones can be visible peeking out of the tonsil crevices. More often, the lumps are hidden behind the back ridges of the tonsils deep in the throat.

Irritation or Itching

The jagged stones can rub against the throat tissue, especially when they become dislodged. This leads to irritation, inflammation, coughing fits and the desire to scratch the area.

Difficult or Painful Swallowing

Large stones that break free of the tonsil crypts have a tendency to get stuck farther down the throat when you swallow. This can make eating and drinking uncomfortable.

Metallic Taste

The sulfur compounds coming from the stones can create an unappealing metallic or chemical taste at the back of the tongue.

Ear Pain

Throat debris dropping down near the Eustachian tubes can lead to clogged ears and dull ear pain.

Complications from Tonsil Stones

In the majority of cases, the stones are asymptomatic and complications do not develop. However, problems that can occasionally arise include:

Repeated Tonsil Inflammation

The debris and gases from the stones can frequently irritate the tonsils. Over time, this can trigger recurring bouts of swollen tonsils or tonsillitis.

Difficulty Swallowing Food or Pills

If a large stone gets firmly lodged farther down the throat near the adenoids and lingual tonsils it can partially block swallowing. This can make it hard to consume an adequate diet.

Halitosis and Social Issues

The severe breath odor produces social anxiety. As a result, people begin avoiding normal activities and interacting with friends, classmates or co-workers.

Rare Abscess Formation

On very rare occasions, a tonsil pocket with stones can progress to a peri-tonsillar abscess requiring antibiotics and surgical drainage.

Diagnosing Tonsil Stones

Distinguishing tonsil stones from other possibilities involves a review of the history along with an oral cavity and throat inspection. Typical diagnostic approaches include:

Physical Exam

Using a flashlight and tongue depressor, your physician visually scans the back of the throat seeking white debris pockets or yellow calcifications in the crevices of the tonsils.

Oral Symptoms

Information on symptoms helps determine if stones may be the cause of bad breath, throat discomfort, ear pain or swallowing difficulties rather than other diseases.

Medical History Factors

Aspects of the medical history that point to tonsil stones include previous issues with chronic tonsillitis, frequent sinus congestion or postnasal drainage.

Treatment Options for Bothersome Tonsil Stones

Tonsil stones that produce no symptoms generally require no treatment or removal. However, various treatment approaches exist for managing troublesome stones and frequently recurring ones.

Specialized Oral Rinses

Saltwater or mouthwash rinses can help to manually dislodge some stones and flush away bacteria to reduce sulfur smells.

Oral Hygiene Improvements

Thorough tooth brushing after eating and using an antiseptic mouthwash reduces debris and bacteria that promote new stone development.

Manual Extraction

Smaller visible stones can sometimes be carefully extracted using sterile swabs, forceps or an oral irrigating device, but this has risks of bleeding and infection.

Drug Treatments

Antibiotics may be used short term to shrink inflamed tonsils and dissipate sizes of large stones.

Tonsillectomy Surgery

In chronic problematic cases resistant to more conservative measures, surgically removing the tonsils prevents new stone formation.

Preventing Future Tonsil Stone Problems

Actions that help deter the development of repeat tonsil stones include:

• Gargling daily with salt water
• Meticulous oral hygiene and regular flossing
• Treating chronic sinus congestion and postnasal drip
• Avoiding dairy products if they aggravate mucus
• Discussing the benefits vs risks of tonsil removal with your ENT specialist
