You’re brushing your teeth and notice it. Tiny white bumps. They look like cottage cheese stuck to your tongue or the inside of your cheeks. You try to scrape them off, and it stings or even bleeds a little. Honestly, it's gross. It’s oral candidiasis—most of us just call it thrush. It's basically a yeast infection, but in your mouth.
Overgrowth happens. Candida albicans is a fungus that lives in almost everyone's mouth, usually behaving itself. But if your immune system dips, or you’ve been on a heavy course of antibiotics, or maybe you’re managing diabetes, that fungus sees an opportunity. It throws a party. Suddenly, you’re looking for home remedies for thrush in mouth because you want that fuzzy, cotton-mouth feeling gone yesterday.
Let's get one thing straight: I’m not talking about "magic" cures. Real science matters here because fungi are stubborn. If you don't treat it right, it just keeps coming back, crawling down your esophagus or making it painful to swallow your morning coffee.
Salt Water and Soda: The Old-School Basics
The most basic, dirt-cheap starting point is a salt water rinse. It’s not fancy. It’s just salt. But salt is naturally antiseptic. It creates an environment that fungus hates.
Take about half a teaspoon of salt and stir it into a cup of warm water. Swish it around for 30 seconds. Spit it out. Don't swallow it; you’re trying to flush the yeast out, not invite it to your stomach.
Then there’s baking soda, or sodium bicarbonate. Research published in the Brazilian Oral Research journal suggests that baking soda has disinfectant properties against Candida. It’s alkaline. Since yeast loves an acidic environment, shifting the pH of your mouth can really mess with its growth cycle. You can make a paste with a little water and apply it directly to the white patches with a cotton swab, or just use it as a rinse like the salt water.

The Probiotic Power Play
You’ve probably heard people scream about yogurt. They aren't wrong, but they often get the "why" wrong. It isn't just about eating dairy; it’s about Lactobacillus. This "good" bacteria produces bacteriocins and organic acids that literally fight the Candida for territory.
If you’re going the yogurt route, it has to be unsweetened. I cannot stress this enough. Sugar is fuel for yeast. If you eat a "strawberry-flavored" yogurt packed with high-fructose corn syrup to treat thrush, you are essentially feeding the enemy while trying to fight it. It’s counterproductive.
Gentian violet is another one. It’s an old-school dye. You can get it over the counter at most pharmacies. It’s messy—it will turn your mouth, your sink, and your clothes bright purple—but it’s a powerful antifungal. Some studies, particularly those focused on resource-limited settings where expensive antifungals aren't available, show it’s remarkably effective. Just be careful; you’ll look like you ate a purple marker for a few days.
Apple Cider Vinegar and the pH War
Apple cider vinegar (ACV) is the internet's favorite "cure-all," but for oral thrush, there is actual logic behind it. It contains acetic acid. A 2014 study in the Journal of Prosthodontics found that ACV showed antifungal properties against Candida species that colonize dentures.
Here is the catch: it’s acidic. Too much can wreck your tooth enamel.

- The Mix: One teaspoon of raw, unfiltered ACV to one cup of water.
- The Method: Swish and spit.
- The Warning: Rinse your mouth with plain water afterward to protect your teeth.
Never use it full strength. You’ll burn your mucosa, and then you’ll have thrush and chemical burns. Not a good look.
Gentler Options: Coconut Oil and Turmeric
Coconut oil pulling is trendy, but for thrush, it’s specifically about lauric acid. Lauric acid has antimicrobial properties. You take a tablespoon of organic coconut oil and swish it for 10 to 15 minutes. It’s a long time. Your jaw might get tired. But the idea is that the oil "pulls" the fungi and debris out of the nooks and crannies of your gums.
Then we have curcumin. That’s the active stuff in turmeric. Curcumin is a heavy hitter when it comes to inflammation. Some lab studies have shown that curcumin can actually inhibit the growth of Candida. Since it isn't very water-soluble, mixing a little turmeric with a tiny bit of oil or milk (unsweetened!) and applying it to the sores might help. Just be prepared for everything to turn yellow instead of purple.
Why Your Toothbrush is Working Against You
Honestly, one of the best home remedies for thrush in mouth isn't something you eat—it's what you throw away. Your toothbrush is a breeding ground. If you have thrush, those fungal spores are living in the bristles. Every time you brush, you’re potentially re-infecting yourself.
Change your toothbrush. Right now. And once the infection clears up, change it again.

If you wear dentures, you’re at higher risk. Yeast loves the space between the prosthetic and the roof of your mouth. You need to soak them daily in a specialized cleaner or a diluted bleach solution (check with your dentist on the ratio) to make sure you aren't just putting the fungus back in your mouth every morning.
When Home Remedies Aren't Enough
I love a good DIY fix, but we have to be real. Thrush is usually a sign that something else is out of whack.
If you have a weakened immune system—maybe from chemotherapy or HIV—thrush can become dangerous. It can spread to the lungs or liver. That’s not a "swish some salt water" situation. If the white patches are spreading down your throat, or if you have a fever, stop the home remedies and call a doctor. You likely need Nystatin or Fluconazole. These are prescription antifungals that do the heavy lifting when your body can't.
Also, check your inhaler. If you use a corticosteroid inhaler for asthma, you are much more likely to get thrush. The "remedy" here is simple: rinse your mouth with water immediately after every puff. It washes the steroid residue away so the yeast doesn't have a chance to settle in.
Actionable Steps for Relief
- Stop the sugar. This is the hardest part. Yeast eats sugar. If you’re sipping soda or eating candy while trying to treat thrush, you’re wasting your time. Cut the sweets for at least two weeks.
- The "Salt and Soda" Rotation. Use the salt water rinse in the morning and the baking soda rinse at night. It’s a double whammy on the fungal environment.
- Sterilize everything. If you’re a nursing mom and your baby has thrush (very common), you both need treatment. Sterilize pacifiers, bottle nipples, and your own breast pump parts. Otherwise, you’ll just keep passing it back and forth.
- Boost the "Good Guys." Take a high-quality probiotic supplement with Lactobacillus acidophilus. This helps restore the balance in your mouth’s microbiome.
- Hydrate. A dry mouth is a vulnerable mouth. Saliva has natural enzymes that keep fungus in check. Drink plenty of water to keep the saliva flowing.
Dealing with thrush is annoying and honestly a bit painful. But by changing the pH of your mouth and being ruthless about hygiene, you can usually clear up mild cases without a trip to the pharmacy. Just keep an eye on it. If it doesn't budge in a week, go see a professional.
