10 common questions about tonsil stones

Come appaiono i calcoli tonsillari?

Calcoli tonsillari, also called tonsilloliths, look like little white or yellow spots on your tonsils. They are made of bits of food, bacteria, or minerals such as calcium which get stuck in the folds and gaps of the tonsils - a pair of small, oval-shaped bits of tissue at the back of your throat.

Tonsil stones are soft but can harden. On rare occasions, tonsil stones can grow larger if they aren’t removed. You’ll probably need a mirror to see them as your tonsils are at the back of your throat.

However, they may also be so small or embedded so deeply in the tissue of the tonsils that they cannot be seen.

• Yellowish bumps or spots at the back of the throat.

• Tonsil redness or swelling.

• An itch or irritation in the back of your mouth or throat.

• Alito cattivo.

• Tosse.

• Difficoltà a deglutire.

• Mal di gola.

• Earache.

Normally, tonsil stones form in the crevices of the tonsils, called tonsillar crypts. However, it’s possible to get them after having your tonsils removed. This could happen if not all the tonsil tissue is removed - and stones may also form in cracks in the scar tissue that develop after surgery.

Not everyone gets tonsil stones. You’re more likely to get them if you have large tonsils and bigger gaps in your tonsils, if you have long term (chronic) sinus problems, or if you have inflamed tonsils (tonsillite).

Poor dental hygiene can also increase the risk of getting tonsil stones, as not brushing and flossing your teeth can lead to the build up of food and bacteria in your mouth.

Not drinking enough water can lead to tonsil stones. This is because a dry throat can lead your body to produce more mucus, which can trap bits of food food and bacteria.

Tonsil stones are usually harmless. However, sometimes tonsil stones can lead to tonsillite - long term inflammation or infection of your tonsils. Tonsillitis symptoms can include a mal di gola, feeling sick, swelling of the tonsils and a high temperature.

There are several reasons why tonsil stones smell. One study found that tonsil stones cause bad breath because they have bacteria and microbes¹. Food bits stuck in the mouth can also smell.

If you swallow a stone, it will likely pass through your digestive system without any issues. A larger stone has the potential to cause a blockage, although this is rare. If you are concerned, you should speak to your doctor.

One way to remove a tonsil stone is to use a water flosser. This can help dislodge a stone without making you gag, which can make you sick or feel nauseous. You can also try gargling with salt water to help loosen stones.

Some people try to push or squeeze out stones using a cotton swab, but this might make you gag. If you do try to remove a stone yourself, don’t use a sharp object as this may cause serious injury.

If you’re struggling to remove a tonsil stone, it is best to speak to your doctor or dentist who will be able to provide advice.

You cannot always prevent tonsil stones - and some people are prone to getting them. However, good orale hygiene can help reduce the likelihood of them developing.

To help prevent tonsil stones, you should:

• Brush your teeth after every meal, or at least twice a day.

• Floss your teeth at least once a day.

• Brush or scrape your tongue regularly.

• Rinse and gargle regularly with an alcohol-free mouthwash or warm salt water.

• Avoid or quit smoking.

• Drink plenty of water, aiming for 8 to 10 glasses of water daily.
