How to Get Rid of Tonsil Stones (and Stop Them Coming Back)
Tonsil stones are small, smelly lumps that form in the pockets of your tonsils. The good news is that getting rid of tonsil stones at home is usually simple: salt-water gargles, a gentle cotton bud or a water flosser on its lowest setting. The bigger job is stopping them coming back.
At Appin Dental Surgery, tonsil stones come up more often than people expect. Usually it's a patient whose teeth and gums look great, yet their breath still isn't fresh. If that sounds familiar, this guide covers how to get rid of tonsil stones safely, what not to poke at them with, and when it's worth seeing a GP instead of a dentist.
What Are Tonsil Stones?
Tonsil stones (tonsilloliths) are hard white or yellow lumps that form when food debris, dead cells and bacteria get trapped in the small pockets of your tonsils and harden. Most are the size of a grain of rice or smaller, though some grow larger.
They're far more common than most people think. A 2013 study of 482 patients found tonsil stones on 46% of CT scans, but only about 7% of dental x-rays of the same people. In other words, plenty of people have small stones and never know.
We often spot them during routine check-ups when we look at the back of the mouth. The patient usually had no idea they were there.
How Do You Know If You Have Tonsil Stones?
The most common sign of tonsil stones is bad breath that doesn't improve with brushing. Other signs include:
White or yellow flecks on your tonsils
A bad taste at the back of your mouth
A feeling that something is stuck in your throat
A mild sore throat or a tickly cough
Ear pain on one side, in some cases
Small, foul-smelling lumps you cough up
Many tonsil stones hide deep in the tonsil pockets, so you can't always see them. And having them doesn't mean you're doing a bad job of brushing. Some people simply have deeper tonsil pockets that trap more debris, which is why tonsil stones can turn up despite good oral hygiene.
Why Do Tonsil Stones Smell So Bad?
Tonsil stones smell bad because the bacteria inside them break down proteins and release sulphur compounds. That's the same rotten-egg chemistry behind most bad breath.
So why doesn't brushing fix it? Because the source sits in your throat, not on your teeth. Some of the most frustrated patients we see have spotless teeth and healthy gums but still notice bad breath, and tonsil stones are one of the first things we look for.
If we can't see any, we'll check other causes, like gum disease or a coated tongue. Our guide to gingivitis and why gums bleed explains how gum problems cause odour too.
How To Get Rid Of Tonsil Stones Safely at Home
Small tonsil stones often fall out on their own when you swallow, cough or eat. If one is bothering you, here's how to remove tonsil stones safely, in this order:
Gargle with warm salt water. Half a teaspoon of salt in a glass of warm water, gargled for 10 to 15 seconds a few times a day, can loosen stones and soothe the area.
Try a firm cough. Coughing is sometimes enough to dislodge a stone that's near the surface.
Use a damp cotton bud. Press gently on the tonsil next to the stone, not on the stone itself, and let it pop out. Use a mirror and a torch.
Use a water flosser on its lowest setting. A water flosser for tonsil stones works best aimed at the tonsil from a little distance. Start low, because a high-pressure jet can damage the delicate tissue.
Rinse afterwards. Gargle with water or an alcohol-free mouthwash to clear any leftover debris.
What not to use: bobby pins, tweezers, toothpicks, fingernails or anything sharp. Tonsils bleed easily. We've seen grazed, bleeding tonsils from people who went at a stone with whatever was in the bathroom drawer.
If a stone won't budge, or if you see blood, stop. Some stones are simply too deep to reach at home.
Can A Dentist Remove Tonsil Stones, or Should You See a Doctor?
A dentist can confirm tonsil stones and rule out dental causes of bad breath, but stubborn or recurring stones are usually managed by a GP or an ENT (ear, nose and throat) surgeon.
Here's how it usually works at our Appin clinic. We check your teeth, gums and tongue first, because those are behind most bad breath. If we see a loose stone sitting near the surface during your visit, we can show you where it is and how to clear it safely. Small stones also show up from time to time on dental x-rays, so a routine dental check-up is often where people first find out they have them.
For stones that keep coming back, sit deep in the tonsil, or cause pain, your GP is the next step. They may refer you to an ENT surgeon, who can talk you through options. These range from smoothing the tonsil pockets with a laser to removing the tonsils (tonsillectomy). healthdirect notes surgery is rarely needed, and is usually reserved for stones that keep returning or cause ongoing symptoms despite good self-care.
How Do You Stop Tonsil Stones from Coming Back?
The best way to prevent tonsil stones is to reduce the bacteria and debris that collect at the back of your mouth. These habits help most:
Clean your tongue every day. The back of the tongue holds a lot of the bacteria that feed tonsil stones. A tongue scraper or your toothbrush both work.
Brush twice a day and clean between your teeth. An electric toothbrush makes it easier for many people.
Gargle after meals. Plain water or salt water flushes out food before it settles into the tonsil pockets.
Drink plenty of water. A dry mouth lets bacteria build up. We see more tonsil stone complaints in patients with dry mouth, especially from medications. If you're on a weight-loss injection, our post on how GLP-1 medications like Ozempic affect your mouth covers why.
Avoid smoking and vaping. Both dry the mouth and irritate the tonsils.
Choose an alcohol-free mouthwash. Alcohol-based rinses can dry the mouth out further.
A regular scale and clean helps too. It removes the plaque and tartar that keep bacteria levels high, so there's less material to end up in your tonsils. If you'd like help building a routine that works for you, our oral hygiene appointments go through it step by step.
When Should You See a GP About Tonsil Stones?
Most tonsil stones are harmless, but it's worth seeing your GP if you notice any of these:
Pain, or trouble swallowing, that doesn't settle within a few days
Fever, swollen glands, or very red, swollen tonsils (signs of tonsillitis)
One tonsil that looks noticeably bigger than the other
An ulcer, white or red patch, or lump in your mouth, throat or neck that lasts longer than 3 weeks
Bleeding from the tonsil that doesn't stop
Stones that keep coming back every few weeks
These usually turn out to be something simple, like an infection. But they deserve a proper look. We check the soft tissues of the mouth and throat at every check-up as part of our oral cancer screening, and we'll refer you to your GP if anything needs a closer look.
Breath Still Not Fresh? Rule Out Your Teeth And Gums First
Tonsil stones are one cause of bad breath, but they're not the most common one. Gum disease, tartar build-up, a coated tongue and dry mouth are behind most cases we see.
If you're dealing with bad breath and you're not sure where it's coming from, a check-up at Appin Dental Surgery will tell you whether it's your teeth, your gums or something further back. We see patients from across Wollondilly, including families in Wilton and Picton, and we can usually point you in the right direction in one visit.
Dr Shelly has cared for patients across Queensland and NSW for over 19 years, and our practice carries on a 30+ year legacy of family dentistry through our sister practice, Bradbury Dental Surgery.
Book a check-up
If bad breath is hanging around and you're not sure why, it's worth getting checked.

Frequently asked questions
Are tonsil stones contagious?
No. Tonsil stones aren't contagious. They form from debris and bacteria already in your own mouth, so you can't catch them from someone else or pass them on.
Can you get tonsil stones without tonsils?
It's rare, but it can happen. Small stones can sometimes form in leftover tonsil tissue after a tonsillectomy, or in the lymphoid tissue at the back of the tongue.
What's the difference between tonsil stones and tonsillitis?
Tonsillitis is an infection that makes the tonsils red, swollen and painful, often with a fever. Tonsil stones are hard lumps of trapped debris that usually cause bad breath rather than illness. Having frequent tonsillitis can enlarge the tonsil pockets and make stones more likely.
Do tonsil stones go away on their own?
Small tonsil stones often come out on their own when you eat, swallow or cough. Larger or deeper stones may stay put, and those are the ones that tend to cause bad breath or a stuck feeling.
Can children get tonsil stones?
Yes, though they're more common in teenagers and adults. If your child has frequent bad breath, white spots on the tonsils or repeated sore throats, see your GP to check for tonsillitis, and book a dental check-up to rule out tooth and gum causes.
