Munh Ke Chhale: Mouth Ulcer Home Remedies That Help, and Ones to Skip
You bite into a pakora, the green chutney touches that one white spot inside your lip, and your eyes water. Mouth ulcers are small, but they can spoil every meal for a week. Here is what genuinely soothes them at home, what makes them worse, and the point where a home remedy should stop and a dentist should take a look.
The short version
- Most common kind: small, round, white or yellow centre with a red rim, usually settles on its own in 7 to 14 days
- Kitchen helpers: warm salt water rinse, a dab of raw honey (adults and children over 1 only), cool curd, soft bland food
- Skip for now: chilli, pickle, vinegar, citrus, crisp papad, very hot chai
- Get it checked: an ulcer lasting more than 2 weeks, one that keeps returning, or one that doesn’t hurt at all

What a chhala actually is
The everyday ulcer most of us get is called an aphthous ulcer. It isn’t an infection you catch from someone, and it isn’t the same as the blister-like cold sore that sits on the outer lip. It’s a shallow break in the soft lining of the mouth. The inner cheek, the underside of the tongue and the inside of the lower lip are its favourite spots.
Why do they come? Often nobody can say for certain. Common triggers people notice are a nick from a toothbrush or a sharp tooth edge, biting your cheek while talking and eating, stress and short sleep, exam or wedding season, hormonal shifts around periods, and some toothpastes. A few people find that certain foods set them off. Low iron, vitamin B12 or folate can sit behind ulcers that keep coming back, which is a blood test question, not a kitchen one.
The good news is simple. A single ordinary ulcer usually fades by itself. Your job at home is to keep it clean, keep it comfortable, and stop irritating it.
The salt water rinse, done properly
This is the oldest instruction in the house and still one of the most sensible. Salt water doesn’t make an ulcer vanish, but it keeps the area clean and many people find it takes the sting down after meals.
- Boil about 250 ml of water (one regular glass) and let it cool until it feels comfortably warm on your wrist, roughly 40°C. Never rinse with hot water.
- Stir in half a level teaspoon of plain salt, about 2.5 to 3 g, until fully dissolved. Table salt or sendha namak both work.
- Take a mouthful and swish gently for 30 seconds, letting it wash over the ulcer. Don’t scrub or gargle hard.
- Spit it out. Don’t swallow. Repeat with the rest of the glass.
- Do this after meals, up to 3 or 4 times a day. Make a fresh glass each time.
It will sting for a second. That’s normal. If it burns badly, halve the salt.
Some families use a pinch of baking soda instead: a quarter teaspoon in half a glass of warm water. It’s milder on the tongue and fine to alternate with salt. Just don’t mix a paste of soda and press it onto the sore, that’s too harsh.
Honey, curd and other soft comforts
A dab of honey
Many desi homes put a little honey straight on a chhala at night. It coats the sore and feels soothing, and some people find meals hurt less afterwards. Use a clean fingertip or cotton bud and apply about a quarter teaspoon of raw honey right on the ulcer before bed, then don’t eat or drink for 20 minutes. Once or twice a day is plenty. Buy from a source you trust and store it in a dry jar away from sunlight, our raw honey guide covers spotting diluted syrup.
Honey must never be given to a baby under 12 months, not on a dummy, not on the gums, not for ulcers or teething. It can carry spores that cause infant botulism. For people with diabetes, a small dab is not a meal, but it still counts, so keep it small.
Cool curd and bland food
Plain, unsweetened dahi straight from the fridge is a gentle food to eat while an ulcer is angry. So is khichdi without chilli, soft daliya, boiled potato, banana, and lukewarm milk. Let tea cool before you sip. Chew on the other side.
Coconut oil or ghee
A thin smear of pure coconut oil or desi ghee over the ulcer is another household habit. It mostly works as a soft coating. Harmless for most people, just use a clean finger.
In Unani thinking, mouth sores are often linked to excess heat and dryness in the body, so the old response leaned towards cooling, moist foods: curd, lassi, sabza (tukh malanga) soaked in water, gulkand and plenty of fluids, while cutting back on fried, spicy and “garam” foods. Ayurvedic homes describe it in terms of aggravated pitta and reach for similar cooling habits, sometimes chewing a few fresh guava or tulsi leaves. These are traditions of comfort and diet, not proven remedies, but the advice to eat soft, cool, plain food during an ulcer happens to be sensible anyway.
Popular totkay that do more harm than good
This is where well-meaning advice goes wrong. Several remedies passed around family WhatsApp groups can burn the tissue and make a small sore larger or slower to settle.
| The totka | Verdict | Why |
|---|---|---|
| Pressing ground haldi onto the ulcer | Not advised | Rough powder scratches raw tissue and stains; no need to risk it |
| Raw alum (phitkari) rubbed on | Avoid | Very astringent, can sting badly and irritate the sore further |
| Crushed aspirin tablet on the sore | Avoid | Acidic, can cause a chemical burn on the lining |
| Clove oil dabbed on neat | Avoid neat | Strong enough to burn soft tissue; never on children |
| Salt placed dry on the ulcer | Avoid | Much harsher than a dilute rinse, damages the edge |
| Warm salt water rinse | Fine | Gentle, cleaning, comfortable |
If you love laung in your cooking, keep it there. The concentrated oil is a different thing altogether.
Everyday habits that cut down on repeat ulcers
You can’t prevent every chhala. You can remove a lot of the small insults that start them.
- Switch to a soft toothbrush and brush with gentle circles, not sawing strokes.
- If ulcers follow a particular toothpaste, try one without sodium lauryl sulfate (SLS) for a month and see.
- Get a sharp tooth edge, broken filling or rubbing brace wire smoothed by a dentist. The same spot ulcerating again and again is a big clue.
- Eat slowly. Many cheek bites happen while talking with a full mouth at a dawat.
- Drink water through the day, 6 to 8 glasses, more in summer.
- Keep a rough note of when ulcers appear. Patterns around stress, periods or certain foods become obvious after a few months.
Cleaning your tongue and keeping the mouth fresh matters too. Our piece on bad breath habits walks through a gentle routine that won’t scrape an ulcer.
A cooling sabza glass
Soak 1 teaspoon (about 5 g) of sabza seeds in 100 ml of water for 15 minutes until they swell into little jelly pearls. Stir into 200 ml of chilled water or thin lassi with a teaspoon of gulkand if you like. It’s refreshing and easy to swallow on a sore day. Skip the gulkand if you’re watching sugar, and have it as a drink, not a remedy.
Get the ulcer examined by a dentist or doctor if any one of these applies: it has lasted longer than 2 weeks; it’s larger than about 1 cm; you get ulcers again and again, or several at once; it doesn’t hurt at all (painless sores need checking); there’s a white or red patch that won’t rub away; it bleeds easily; you also have fever, swollen glands in the neck, weight loss, sores on the genitals or eyes, or ongoing diarrhoea. Smokers and anyone who chews paan, gutka, naswar or chaalia should never wait on a mouth sore, get it seen early. Babies and small children with mouth sores, especially if they refuse to drink, need a doctor the same day because dehydration comes quickly. If you’re pregnant, breastfeeding or taking regular medicine, check with your pharmacist before using any medicated gel. Some medicines can themselves cause mouth ulcers, so mention everything you take.
A simple day plan while it settles
Morning: brush gently, rinse with warm salt water. Breakfast of soft paratha without achaar, or daliya. Midday: cool dahi with rice, water through the afternoon. Evening: another salt rinse after dinner. Bedtime: a small dab of honey on the ulcer if you’re an adult. Repeat. Most people notice the pain easing within three or four days.
And if a mouth ulcer is joined by a burning feeling from something hot you drank, the rules for cooling skin burns are rather different, which we explain in our guide to kitchen burn first aid. For more gentle household practice, browse Desi Remedies.
What people ask about munh ke chhale
How can I get rid of a mouth ulcer fast at home?
There’s no instant fix, but you can make it much less painful while it settles. Rinse with warm salt water after meals, eat soft, cool, bland food, and keep chilli and achaar away from it. Most people feel the pain easing within three or four days.
How long does a mouth ulcer take to go away?
An ordinary small ulcer usually fades in 7 to 14 days. If one has lasted longer than two weeks, have a dentist or doctor look at it.
What causes mouth ulcers?
Often nobody can say for sure. Common triggers are a nick from a toothbrush or sharp tooth, biting your cheek, stress and short sleep, hormonal shifts around periods and some toothpastes. Ulcers that keep coming back can be linked to low iron, B12 or folate, which a blood test can check.
How often can I rinse with salt water for a mouth ulcer?
After meals, up to 3 or 4 times a day. Use half a level teaspoon of salt in a glass of comfortably warm water, swish gently for 30 seconds and spit. If it burns badly, halve the salt.
Does honey help mouth ulcers?
Many homes dab about a quarter teaspoon of raw honey on the ulcer at bedtime, and it coats the sore nicely. Don’t eat or drink for 20 minutes after. Never give honey to a baby under 12 months, and if you have diabetes, keep the dab small.
What foods should I avoid while I have a mouth ulcer?
Skip chilli, achaar, vinegar, citrus, crisp papad and very hot chai until it settles. Cool dahi, plain khichdi, soft daliya, banana and lukewarm milk are easier to eat.
Are mouth ulcers contagious?
The common aphthous ulcer isn’t an infection you catch or pass on. It’s different from a cold sore, the blister that sits on the outer lip.
Can I put phitkari or clove oil on a mouth ulcer?
Better not. Alum is very astringent and can irritate the sore, and neat clove oil is strong enough to burn soft tissue. A crushed aspirin tablet can cause a chemical burn too. A warm salt water rinse is the gentler choice.
Is haldi good for mouth ulcers?
Drinking lukewarm haldi doodh is fine if you enjoy it, as long as it’s cooled so it doesn’t sting. Pressing dry turmeric powder on the ulcer isn’t a good idea, because rough powder scratches raw tissue. Our haldi doodh recipe shows a gentle version.
Why do I keep getting mouth ulcers again and again?
Repeat ulcers usually have a trigger worth finding. A sharp tooth edge or rubbing brace wire, a toothpaste with SLS, stress, periods or low iron, B12 or folate are common ones. Keep a note of when they appear, and see a dentist or doctor, since frequent ulcers deserve a proper check.
When is a mouth ulcer serious?
Get it examined if it lasts beyond 2 weeks, is larger than about 1 cm, doesn’t hurt at all, bleeds easily, or sits with a white or red patch that won’t rub away. Fever, swollen neck glands, weight loss or sores on the genitals or eyes also need a doctor. Paan, gutka or naswar users should never wait.
Are mouth ulcers caused by garmi in the stomach?
That’s the traditional way of describing it. In practical terms, triggers are usually injury, stress, some toothpastes, hormones or low iron and vitamins. A heavy, spicy diet can leave you feeling worse overall, so eating lighter food is reasonable either way.
My child keeps getting ulcers. Is honey okay?
Only if the child is over 1 year old, and only a tiny dab. Repeated ulcers in a child deserve a visit to the paediatrician or dentist instead of more home remedies. A baby or small child with mouth sores who refuses to drink needs a doctor the same day, because dehydration comes on quickly.
Can toothpaste cause mouth ulcers?
Some people find ulcers follow a particular toothpaste, often one with sodium lauryl sulfate (SLS). Switching to an SLS-free paste for a month is an easy way to find out. A soft brush and gentle circles help too.
Is baking soda rinse good for mouth ulcers?
A quarter teaspoon of baking soda in half a glass of warm water is a mild rinse that many find easier on the tongue than salt. It’s fine to alternate the two. Don’t press a soda paste onto the sore, though; that’s too harsh.
Is coconut oil or ghee good for mouth ulcers?
A thin smear works mainly as a soft coating, and it’s harmless for most people. Use a clean finger. It won’t speed things up much, but it can make the sore feel less raw.
Can medicines cause mouth ulcers?
Some can. If ulcers started after a new tablet, mention it to your doctor or pharmacist, and tell them everything you take. Don’t stop a prescribed medicine on your own; ask first. If you’re pregnant or breastfeeding, check before using any medicated gel.
