Dr. Chrysoula I. Liakou MD, PhD
- Treated online: Yes, usually. Video assessment of your tonsils and advice on removal and prevention; antibiotics are not needed.
- What they are: small, hard white or yellow lumps of trapped debris and bacteria that form in the pockets (crypts) of the tonsils.
- Symptoms: often none; larger stones cause bad breath, a feeling of something stuck in the throat, a sore throat or ear pain.
- See a doctor: if one tonsil is clearly larger than the other, you have an ulcer or a lump in the neck, or one-sided throat pain lasts 3 weeks.
- Emergency: tonsil stones are not dangerous, but call 112 for difficulty breathing or being unable to swallow your saliva.
Tonsil stones themselves are harmless. Do not book a video appointment if you have difficulty breathing, are drooling because you cannot swallow your saliva, cannot open your mouth fully, or have severe pain on one side of your throat with a muffled voice. These can signal an abscess: call 112.
Can an online doctor treat tonsil stones?
Yes. Tonsil stones sit on the surface of the tonsils, where a camera and a good light can see them clearly. The doctor confirms they are stones rather than tonsillitis or something else, looks for the few signs that need a specialist, and agrees a plan with you to manage them. Tonsil stones do not need antibiotics. Difficulty breathing or swallowing needs emergency care instead.
How an online consultation helps with tonsil stones
- A clear look at your tonsils: With your phone torch and the camera close to your mouth, the doctor can see the stones and the pockets they sit in, and compare the two tonsils.
- Stones or something else?: White spots can also be tonsillitis, thrush or glandular fever. The doctor tells them apart, so you get the right treatment.
- Safe removal and prevention: You learn how to dislodge stones without damaging your tonsils, and the daily habits that make them less likely to come back.
- Bad breath tackled properly: If bad breath is the main problem, the doctor also looks at the other common causes, such as gum disease, reflux and a dry mouth.
What the doctor checks in an online tonsil stones consultation
The consultation follows a fixed order, and the emergency signs come first. The doctor asks about:
- Airway and abscess signs: difficulty breathing or swallowing, drooling, trouble opening your mouth, or severe pain on one side.
- The tonsils themselves: the size and colour of the stones, whether the tonsils are red or swollen, and whether one tonsil is larger than the other.
- Red flags: an ulcer, a lump in the neck, one-sided throat or ear pain that does not go away, a hoarse voice, smoking, and losing weight without trying.
- Your symptoms: bad breath, a feeling of something stuck, a sore throat, and how often the stones come back.
- Past infections: how many times you have had tonsillitis in the last year or two.
Before the call, find a bright light, such as your phone torch, and a mirror. The doctor may ask you to say ‘aah’ with your tongue out, or to hold your tongue down gently with the handle of a clean spoon.
What are tonsil stones?
Tonsil stones, or tonsilloliths, are small, hard lumps that form in the crypts, the tiny pockets on the surface of the tonsils. Food debris, dead cells, mucus and bacteria collect in these pockets, which is why the stones can smell bad, and harden over time as minerals such as calcium build up. They look like tiny white or yellow pebbles, you may have one or several, and they range from the size of a grain of rice to a small pea.
They are common: up to 10% of people have them, most often young adults, and they are not often seen in children. They are more likely with deep tonsil crypts and after repeated tonsillitis, because repeated infections leave the crypts enlarged. Poor oral hygiene and not drinking enough make them more likely, and smoking irritates the throat further. Tonsil stones are not contagious.
Tonsil stones symptoms
Many people have small tonsil stones without knowing. Larger stones can cause:
- bad breath that does not go away with brushing
- white or yellow lumps you can see on your tonsils, or cough up
- a feeling of something stuck at the back of the throat
- a sore throat or discomfort on one side
- earache, because the throat and ear share nerves
- a cough or a bad taste in the mouth
Tonsil stones do not usually cause a fever, swollen neck glands or feeling unwell. Those point to an infection such as tonsillitis.
Tonsil stones, tonsillitis or something else?
White spots on the tonsils have several causes. These are the ones doctors tell apart:
Swipe sideways to compare →
| Condition | What you see and feel | What to do |
|---|---|---|
| Tonsil stones | Firm white or yellow lumps in the tonsil pockets, bad breath, no fever | Self-care; see a doctor if they bother you |
| Tonsillitis | Red, swollen tonsils, sometimes with white patches, a sore throat and fever | Pain relief; antibiotics only if it is bacterial |
| Strep throat | Swollen tonsils with pus, fever, tender neck glands, no cough | Assessment; antibiotics |
| Glandular fever | Very swollen tonsils, exhaustion and swollen glands, often in young adults | Assessment and rest |
| Oral thrush | White patches that wipe off, often after antibiotics or with a steroid inhaler | Antifungal treatment |
| One enlarged tonsil | One tonsil clearly bigger than the other, sometimes with an ulcer or a neck lump | Urgent ear, nose and throat referral |
Doctors usually recognise tonsil stones by looking at the throat, and a dentist sometimes spots them first. Stones hidden deep in a tonsil can show up on an ultrasound, X-ray or CT scan, but a scan is usually needed only when another cause is suspected.
How to get rid of tonsil stones safely
Most tonsil stones fall out on their own. If one bothers you, these steps help it loosen and come out:
- Gargle with warm salt water, especially after meals: half a teaspoon of salt in a glass of warm water, then spit it out.
- Cough firmly or swallow hard, which can push a loose stone out.
- Brush the back of your tongue gently with a soft toothbrush.
- If a stone sits right at the surface, press very gently beside it with a clean cotton bud to ease it out.
- A water flosser on a low-pressure setting can help flush stones out of the pockets.
- Use an antiseptic mouthwash, such as one containing chlorhexidine, for a short period.
Do not dig at your tonsils with fingernails, tweezers, toothpicks or other sharp objects. Repeatedly squeezing or scraping them causes inflammation, bleeding and pain. Spitting out a stone that comes loose is fine, and swallowing one does no harm.
How to stop tonsil stones coming back
Tonsil stones tend to come back as long as the crypts are there, but these habits make them less likely:
- Brush twice a day and clean between your teeth, including the back of your tongue.
- Gargle with salt water after meals.
- Drink plenty of water to keep your mouth moist.
- Stop smoking.
Some people try cutting down on dairy. None of the home measures has strong evidence behind it, so good oral hygiene and regular gargling are the sensible place to start.
Are tonsil stones dangerous, and should the tonsils come out?
Tonsil stones are not dangerous, and there is no evidence that they cause long-term health problems. They are a nuisance rather than a disease. Rarely, a very large stone can cause swelling and make swallowing difficult, which needs a doctor’s review.
Removing the tonsils (tonsillectomy) is not recommended for tonsil stones alone, because the operation carries real risks, including significant pain afterwards, infection and bleeding. It may be considered if you also have repeated, severe tonsillitis. If self-care has not worked, a specialist can remove a troublesome stone under local anaesthetic in clinic. Some ear, nose and throat specialists offer laser treatment to smooth the surface of the tonsils, called cryptolysis.
Which tonsil stones treatment might the doctor recommend?
Most people need reassurance and a self-care plan. This is the decision framework the doctors use, aligned with ear, nose and throat guidance.

| What you have | Likely first step | Suitable for online care? | When in-person care is needed |
|---|---|---|---|
| Occasional small stones, no other symptoms | Gargling, oral hygiene, letting them fall out | Usually yes | Not usually needed |
| Frequent stones with bad breath | A prevention plan, and a check for other causes of bad breath | Usually yes | If bad breath persists despite good oral hygiene |
| Stones with red, swollen tonsils and a fever | Assessment for tonsillitis | Usually yes | If you cannot swallow fluids or one side swells |
| Stones with repeated tonsillitis | A review of the pattern; ear, nose and throat referral if severe and frequent | Assessment and referral | Tonsil surgery is planned in person |
| One enlarged tonsil, an ulcer, a neck lump or one-sided pain for 3 weeks | Urgent referral to an ear, nose and throat specialist | Assessment and referral | Yes, an examination is needed |
| Difficulty breathing or swallowing saliva, muffled voice | Emergency care | No | Call 112 now |
Not sure whether those white spots are tonsil stones? A doctor can tell you in one consultation.
See available times →Treatment options for tonsil stones
What you can do yourself
Gargling, gentle brushing of the tongue and coughing out loose stones, as described above, are the main treatment. If your throat is sore, take paracetamol or ibuprofen at the dose on the pack. Ibuprofen does not suit everyone, including people with a stomach ulcer, kidney problems or heart failure, or anyone who is pregnant.
Prescription treatment
A prescription is never issued without a consultation. Tonsil stones themselves do not need a prescription. If you also have bacterial tonsillitis, the doctor may prescribe an antibiotic, and if you have oral thrush, an antifungal treatment. If the doctor prescribes, use the prescription at a pharmacy near you.
What does not help
Antibiotics do not remove tonsil stones or stop them forming. Digging the stones out with sharp objects does more harm than good.
Special situations
Bad breath that does not go away
If bad breath continues after the stones are gone, the cause may lie elsewhere: gum disease, a dry mouth, reflux, smoking or some foods. Read more about bad breath.
Repeated tonsillitis
If you get tonsil stones and frequent bouts of tonsillitis, it is the pattern of infections, not the stones, that decides whether surgery is worth considering.
Tonsil stones in pregnancy
Tonsil stones in pregnancy are managed in the same way, with gargling and oral hygiene. Paracetamol is the usual choice if your throat is sore.
Children
Mobi Doctor consultations are for adults aged 18 and over. A child who is unwell needs a paediatrician or a local doctor in person, and emergency signs in a child mean 112.
When tonsil stones are treated online, and when you need in-person care
Treated online: suspected tonsil stones, bad breath linked to the tonsils, advice on safe removal and prevention, telling stones apart from tonsillitis or thrush, and referral when a specialist is needed.

Frequently asked questions about tonsil stones
What are tonsil stones?
Tonsil stones, or tonsilloliths, are small, hard white or yellow lumps that form in the pockets on the surface of the tonsils. They are made of trapped food debris, dead cells, mucus and bacteria that harden over time, which is why they can smell bad.
What do tonsil stones look like?
They look like tiny white or yellow pebbles sitting in the pockets on the surface of the tonsils. You may have one or several, and most range from the size of a grain of rice to a small pea. They feel hard and often smell bad when they come out.
How do you know if you have tonsil stones?
You may see white or yellow lumps on your tonsils or cough one up, and notice bad breath, a bad taste or a feeling of something stuck in your throat. Many small stones cause no symptoms. A doctor can usually confirm them by looking at the throat, and a scan is rarely needed.
What causes tonsil stones?
They form when debris and bacteria collect in the crypts, the small pockets in the tonsils. Deep crypts, repeated tonsillitis and poor oral hygiene make them more likely. They are common and are not a sign of poor health.
How do I get rid of tonsil stones at home?
Most fall out on their own. Gargling with warm salt water, coughing firmly and gently brushing the back of your tongue help loosen them, and a stone at the surface can be eased out with a clean cotton bud. Do not dig at your tonsils with sharp objects.
Are tonsil stones dangerous?
No. Tonsil stones are harmless and there is no evidence they cause long-term health problems. See a doctor if one tonsil is clearly larger than the other, or you have an ulcer, a lump in the neck or one-sided throat pain lasting 3 weeks.
How long do tonsil stones last?
A tonsil stone can sit in its pocket for weeks or months, growing slowly, until it works loose during coughing, swallowing or gargling, or is removed; small ones often come and go unnoticed. Tonsil stones tend to come back in the same person because the tonsil pockets that trap debris do not change, so most people manage them with gargling and oral hygiene rather than expecting them to stop, and only removal of the tonsils ends them for good.
Why do tonsil stones smell so bad?
The bacteria in the trapped debris produce foul-smelling compounds, which is why tonsil stones are a common cause of bad breath. If bad breath continues after the stones are gone, look at other causes such as gum disease, a dry mouth or reflux.
Why do I keep getting tonsil stones?
Repeated tonsil infections leave the crypts enlarged, so debris keeps collecting there, and new stones can form as long as the crypts are there. Brushing twice a day, cleaning the back of the tongue, gargling after meals, drinking plenty of water and not smoking make them less likely.
Is it OK to pick out, spit out or swallow tonsil stones?
Spitting out a loose stone is fine, and swallowing one does no harm. A stone at the surface can be eased out gently with a clean cotton bud, but do not dig at your tonsils with fingernails, tweezers or toothpicks, which causes bleeding, swelling and pain.
Should I have my tonsils removed for tonsil stones?
Usually not. Tonsil removal carries risks such as pain, infection and bleeding, and is not recommended for tonsil stones alone. It may be considered if you also have repeated, severe tonsillitis.
Can an online doctor help with tonsil stones?
Yes. A doctor can see your tonsils on camera with a good light, confirm whether the spots are stones or an infection, explain safe removal and prevention, and refer you to a specialist if anything needs a closer look.
When should I see a doctor about tonsil stones?
See a doctor if the stones keep coming back and bother you, if bad breath persists, or if one tonsil is larger than the other, you have an ulcer, a neck lump or one-sided pain for 3 weeks. Call 112 for difficulty breathing or swallowing saliva.
