Understanding Tonsil Stones (Tonsilloliths)
Tonsil stones, also known as tonsilloliths or cryptic tonsils, are small accumulations of debris and calcified material that form in the crypts and crevices of the tonsils. Though relatively common, tonsil stones can cause discomfort and bad breath. Learning more about the causes, symptoms, and treatment options for tonsil stones can help you determine if you have them and find relief.
What Are Tonsil Stones?
Tonsils are oval-shaped tissue masses located at the back of the throat, one on each side. Tonsils contain crevices and pockets called crypts where bacteria and other debris can collect. When this debris hardens and calcifies, it can form into a solid white or yellow irregularly-shaped lump - a tonsil stone.
Tonsil stones vary in size, ranging from smaller than a peppercorn to as large as a pea. Some people only have a single tonsil stone at a time, while others may have multiple stones. They can occur in one or both tonsils.
What Causes Tonsil Stones?
A few key factors allow tonsil stones to form:
- Trapped debris - Food particles, mucus, dead cells, and other debris can get lodged in the tonsil crypts.
- Oral bacteria - The trapped debris mixes with oral bacteria to create a thick biofilm.
- Calcification - Over time, the biofilm hardens and calcifies into tonsil stones.
People who experience chronic inflammation of the tonsils, known as chronic tonsillitis, are more prone to developing tonsil stones. Recurrent bouts of tonsillitis cause the crypts to enlarge, allowing more debris to accumulate. Conditions that cause chronic dry mouth may also increase risk as less saliva is available to flush away debris and bacteria.
Common Symptoms of Tonsil Stones
Tonsil stones occurring deep within the tonsil crypts often produce no symptoms. Stones that cause symptoms may:
- Cause bad breath - The sulfur compounds released by bacteria create foul-smelling breath.
- Irritate the throat - Large stones may cause discomfort or a scratchy, tickling feeling in the throat.
- Trigger coughing episodes - Coughing helps expel the stones, especially when swallowing.
- Cause difficulty swallowing - Large stones can partially obstruct the throat, making swallowing painful.
- Appear as visible white/yellow dots - Stones may be noticeable on the surface of the tonsils.
When to See a Doctor
Most tonsil stones do not require medical treatment. However, see your doctor or otolaryngologist if you have:
- Persistent sore throat or swallowing difficulties
- Enlarged or swollen tonsils
- Frequent tonsil stone formation despite good oral hygiene
- Tonsil stones that keep returning after removal
- Bad breath that persists despite stone removal
These may be signs of an underlying infection or condition requiring further evaluation and treatment.
Diagnosing Tonsil Stones
Your doctor can often diagnose tonsil stones through a simple visual exam. Shining a light at the back of the mouth allows clear view of the tonsils and any white spots consistent with calcified stones. Gently pressing the tonsils with a cotton swab may dislodge some stones.
Imaging techniques like CT scans or MRIs can detect buried tonsil stones that cannot be viewed. Blood tests help determine if infection is contributing to recurrent tonsillitis and stone formation.
Treatment and Removal of Tonsil Stones
Several methods can help dislodge, treat, or remove tonsil stones:
- Saltwater gargles - Gargling daily with warm salt water may help loosen stones.
- Oral hygiene - Brushing teeth and tongue after meals removes debris and bacteria.
- Prescription mouthwashes - Medicated rinses reduce bacteria and oral biofilm.
- Manual removal - Your doctor may remove larger stones using a cotton swab or water irrigation device.
- Tonsillectomy - Surgically removing the tonsils prevents recurrent tonsil stones.
Making lifestyle changes like drinking more water, quitting smoking, and improving oral hygiene can also help impede stone formation.
Home Remedies for Removing Tonsil Stones
You can try these safe, simple home remedies for dislodging tonsil stones:
- Use a cotton swab or toothbrush to gently loosen and remove visible surface stones.
- Try carefully pressing the tonsils with a clean finger to expel stones.
- Rinse and gargle with an oral irrigator on lowest pressure setting.
- Gargle frequently with warm salt water to draw out stones.
- Suck on lozenges or drink carbonated beverages to stimulate stone expulsion.
Avoid using sharp tools or excessive force, which can damage the tonsils and worsen stone formation. Seek medical care if home remedies do not adequately remove bothersome tonsil stones.
Preventing Tonsil Stones
You may be able to help prevent tonsil stones through these daily oral hygiene measures:
- Gently brush teeth, tongue, gums, and roof of mouth twice daily.
- Floss daily to remove food particles between teeth.
- Rinse mouth thoroughly after eating or drinking sugary/acidic foods and beverages.
- Drink plenty of water to stay hydrated and promote saliva flow.
- Gargle mouthwash; antiseptic varieties reduce bacteria best.
Avoid smoking and secondhand smoke, which irritate the throat and tonsils. Using a humidifier at night also keeps nasal passages moisturized, reducing bacteria that can migrate to the throat area.
When Tonsil Stones Won't Go Away
If good oral hygiene, lifestyle changes, and home remedies do not resolve troublesome tonsil stones, discuss more aggressive treatment with your doctor. Options may include:
- Powered irrigators - Devices that use water jets to blast away stones.
- Ultrasound devices - Break up stones with ultrasonic vibration.
- Curettage - Scraping away debris in crevices of tonsils.
- Laser ablation -Destroying tonsil tissue to eliminate crypts.
- Radiofrequency ablation - Using heat to smooth tonsil crypt surfaces.
- Tonsillectomy - Permanently removing the tonsils if other measures fail.
The Bottom Line
Tonsil stones are generally harmless accumulations that occur in the tonsil crypts. While mostly asymptomatic, larger stones may cause bad breath, sore throat, and difficulty swallowing. Improving oral hygiene, manually removing visible stones, and gargling with salt water help manage tonsil stones in most cases. Persistent, recurring tonsil stones may require removal procedures or tonsillectomy as a last resort.
