Home remedies for mouth ulcers can lower pain fast and help your mouth feel normal again. Most mouth ulcers heal in 7 to 14 days. You will recover sooner when you keep the sore clean, stop rubbing it, and avoid stinging foods. Canker sores inside the mouth are not contagious, unlike cold sores on the lip edge. If your sore lasts more than two weeks, you need a checkup.

ToggleWhat Are Mouth Ulcers?
A mouth ulcer is a small, open sore in the mouth. Doctors often call the common kind “canker sores” or “aphthous ulcers.” They show up on soft areas like the inner cheek, inside the lips, under the tongue, and the soft gum line.
Canker sores come in a few patterns.
- Minor ulcers are the usual type. They are small and round. They often heal without scars.
- Major ulcers are larger and deeper. They can hurt more and last longer, and may leave a scar in some people.
- Herpetiform ulcers are not herpes. They are many tiny sores that can join into one larger sore.
- Cold sores are different as they are caused by virus. They often appear at the lip border and can spread to others. Canker sores stay inside the mouth and do not spread by kissing or sharing cups.
You need home remedies for mouth ulcers when you get that sharp, raw pain during meals. You can ease that pain, but you also want to know what caused the sore.
Typical Symptoms
A mouth ulcer often starts with a tender spot. You may feel a sting when toothpaste hits it, and pain when salty or sour food touches it.
Within a day, you might see a sore with a pale center. The center can look white, yellow, or gray. The skin around it can look red.
You can also notice dry mouth, bad breath, or a “hot” feeling in that area. Talking can hurt if the sore sits where your teeth rub.
If you also have a fever, feel weak, or see swelling in the neck, do not brush it off. That can point to a bigger issue.
You can try home remedies for mouth ulcers if the pain feels out of proportion to the size. That is normal because the mouth has lots of nerve endings.
Common Causes (Trauma, Infection, Deficiency)
A lot of ulcers start from tiny damage. You might bite your cheek. A sharp chip might scrape your gum. A hard toothbrush can rub the same spot every day. Braces and aligners can also create friction.
Some triggers come from the mouth’s “surface shield.” One surprising example is sodium lauryl sulfate, also called SLS. It is a foaming ingredient in many toothpastes. SLS toothpaste is linked to more frequent recurrent aphthous ulcers in some people. Switching to an SLS-free toothpaste reduced ulcer count and pain. This does not mean SLS is the only cause. It can be one trigger for some mouths.
Deficiencies can matter too. Low iron, low vitamin B12, or low folate can make ulcers more likely. Your mouth lining can become more fragile when your body lacks key nutrients. If you get ulcers again and again, a clinician may suggest blood tests.
Infections can also cause mouth sores, but not all sores mean infection. Cold sores involve a virus and look different in location and behavior.
Some long-term health problems can be linked with repeated mouth ulcers. A clinician thinks about this when ulcers are severe, frequent, or paired with other symptoms. That is one reason home remedies for mouth ulcers work best when you also watch for warning signs.
Natural Remedies For Mouth Ulcers
Some natural remedies for mouth ulcers help in two ways. They reduce pain and also create a protective layer so the sore stops getting hit by food and teeth. None of these should promise a “cure.”
Honey: How To Apply
Honey is one of the best-studied options among home remedies for mouth ulcers . Topical honey reduces pain, redness, and ulcer size in minor aphthous ulcers.
How you use it matters.
- Wash your hands.
- Dry the sore gently with a clean tissue.
- Dab a small amount of honey directly on the ulcer.
- Hold your mouth open for about 20 seconds. Let it sit.
- Avoid eating or drinking for about 10 minutes.
- Repeat a few times daily.
Do not use honey for babies under 1 year. That rule matters for safety. If your ulcer feels worse after honey, stop. Some people react to certain honey types. This is a simple way to use home remedies for mouth ulcers without harsh chemicals.
Saltwater Rinse: Method
Saltwater does not “kill” every germ, but it can help clean the area and calm irritation. It also helps flush food bits away so the sore does not stay dirty.
- Mix half a teaspoon of salt in one cup of warm water.
- Swish gently for 20 to 30 seconds.
- Spit it out.
- Do this after meals and before bed.
If salt stings too much, use a little less. You can use saltwater as the base of home remedies for mouth ulcers because it is simple and low-risk.
Aloe Vera Gel: Topical Use
Aloe gel can feel cooling on irritated tissue. Research on natural agents for recurrent aphthous stomatitis suggests some natural products, including aloe-based options, may reduce pain and ulcer size, but study quality varies.
- Use food-grade aloe gel if possible.
- Dry the sore area gently.
- Apply a thin layer.
- Do not eat for about 10 minutes.
- Use it a few times daily if it feels soothing.
- Stop if you notice burning or a rash.
Aloe can fit well with home remedies for mouth ulcers when you want a gentle coating.
Coconut Oil / Oil Pulling
Coconut oil can form a smooth barrier over the sore. That barrier can cut friction and lower stinging during meals. Many people like it because it feels mild.
You can dab a small amount on the ulcer after brushing. You can repeat it during the day.
“Oil pulling” means swishing oil in your mouth for several minutes, then spitting it out. Some people like it, but it can hurt if your mouth feels raw. If swishing hurts, skip it and stick to dabbing. Comfort comes first with home remedies for mouth ulcers .
Baking Soda Paste: Quick Recipe
Baking soda can change the mouth’s acidity and may reduce irritation for some people. It can also feel drying if you use too much.
- Mix one teaspoon of baking soda with a few drops of water.
- Make a thick paste.
- Apply a small amount on the sore for about 30 to 60 seconds.
- Rinse gently with water.
- Use it once daily at first. Stop if it feels harsh.
This works best as a short helper, not an all-day fix. It can be one more tool in home remedies for mouth ulcers .
Mouth Ulcer Treatment At Home
You get better results when you protect the sore from repeat injury. That is the heart of mouth ulcer treatment at home . You want less rubbing, less stinging, and a cleaner mouth surface.
Oral Hygiene Tips
Brush with a soft toothbrush. Hard bristles can reopen the sore. Brush slowly around the ulcer area.
If your toothpaste burns, consider an SLS-free toothpaste. SLS-free toothpaste can reduce ulcer number, pain, and duration for some people with recurrent sores.
Floss once a day, but do not “snap” the floss into sore spots. Gentle cleaning helps healing.
Topical OTC Gels — When To Use
Over-the-counter mouth gels can help when pain blocks eating or sleep. Many gels create a thin film. Some include numbing ingredients.
Use them before meals or before bed. Follow label rules. If you feel swelling, rash, or trouble breathing, stop and get help.
OTC gels are not the only answer. They work best alongside home remedies for mouth ulcers like salt rinses and gentle care.
Pain Control (Analgesics, Numbing Gels)
If pain feels strong, you can use common pain relievers that you already tolerate. Dosage varies by age and condition. Doctors usually guide people with stomach issues, kidney disease, or blood thinner use.
Numbing gels can provide temporary relief, but they can also lead to accidental cheek biting. Use a small amount. Avoid hot drinks right after numbing, since you may burn your mouth without noticing.
Hydration & Soft Diet
Dry mouth slows healing. Sip water often. Choose soft foods that do not scrape. Try yogurt, eggs, oats, mashed potatoes, and warm soups that are not hot.
Cut food into small pieces. Chew slowly. Keep meals simple until the sore calms. This part of mouth ulcer treatment at home can shrink pain within a day even if the sore still exists.
Herbal Remedies For Mouth Ulcers
Some herbal remedies for mouth ulcers show promise, but the research quality varies. A large review of topical interventions for recurrent aphthous stomatitis found honey among better performers, and it also noted several other topical options with mixed evidence across trials.
Turmeric Paste (Anti-Inflammatory)
Turmeric contains curcumin, a compound linked with anti-inflammatory effects. Some trials of natural products for recurrent aphthous stomatitis include curcumin-based approaches, but methods differ across studies.
- You can mix turmeric powder with a little water to form a paste.
- Apply a small amount on the ulcer.
- Leave it for about one minute.
- Rinse gently.
- Turmeric can stain. Go light. Stop if it irritates you.
This can pair with home remedies for mouth ulcers like salt rinses, not replace them.
Clove Oil (Antiseptic Use)
Clove oil contains eugenol (a natural numbing compound). It can sting if used straight. Always dilute it.
Mix one drop of clove oil into one teaspoon of a carrier oil like coconut oil. Dab it on the sore with a cotton swab. Use once daily at first. If it burns, stop.
Clove oil can be helpful, but it is strong. Use caution with herbal remedies for mouth ulcers .
Chamomile Compress
Chamomile can feel soothing. You can use it as a cooled tea compress.
Brew chamomile tea. Cool it until it feels warm, not hot. Soak clean cotton or gauze. Hold it on the sore for one to two minutes. Repeat once or twice daily if it feels good.
If you have a ragweed allergy, chamomile can trigger reactions in some people. Stop if you notice itching or swelling.
Basil (Tulsi) Leaf Rinse
Tulsi (holy basil) is used in many homes as a gentle rinse. Evidence for Tulsi in mouth ulcers is not as strong as the honey data. If you try it, treat it as comfort care, not a proven treatment.
Boil a few washed leaves in water. Cool the water until warm. Swish gently for 20 seconds. Spit it out. If it stings, stop.
How To Reduce Mouth Ulcer Inflammation
Cold Compress Technique
When your mouth feels “on fire,” cold gives quick control. Let a small ice chip melt near the sore. Move it around slowly. Do not press hard. Cold narrows tiny blood vessels, so swelling can drop for a while. That makes eating and talking easier. Pair this with home remedies for mouth ulcers that protect the sore, like honey or coconut oil, so the area stays calm after the cold fades.
If ice hurts your teeth, chill water and sip it often. You still get a cooling effect with less shock.
Anti-Inflammatory Foods To Add
Food cannot “erase” a sore overnight. But the right foods stop extra irritation and help your mouth lining repair.
- Choose soft protein. Eggs, tofu, yogurt, and well-cooked lentils work well. Protein supports tissue repair.
- Add gentle fats. Olive oil and soft avocado can make meals slide down with less rubbing.
- Pick cooked vegetables. Steam carrots, pumpkin, or spinach until very soft. Raw salad can scrape the sore.
- Try smooth blends. A banana-oats smoothie (no citrus) can be a full meal when chewing hurts.
These ideas help reduce mouth ulcer inflammation because your sore gets fewer hits per day.
Avoiding Irritants (Toothpaste, Alcohol)
Some products keep an ulcer angry. Alcohol-based mouthwash can sting badly. Choose alcohol-free rinses or plain saltwater instead. Also, watch your toothpaste. Some people with frequent canker sores do better after switching away from SLS (sodium lauryl sulfate), a foaming ingredient.
That change can support reduce mouth ulcer inflammation without adding new medicines.
Gentle Brushing And Salt Rinse
You heal faster when you keep your mouth clea,n but do not scrape the sore.
Use a soft brush. Brush slowly near the ulcer. Rinse after meals with warm saltwater. This helps wash away food bits that stick to the sore.
This simple routine fits both mouth ulcer treatment at home and home remedies for mouth ulcers because it reduces new damage while the tissue rebuilds.
Foods To Avoid With Mouth Ulcers
Citrus And Acidic Fruits
Sour foods can burn an open sore. Oranges, lemons, grapefruit, pineapple, and tomatoes often sting. Even “healthy” lemon water can feel like salt on a cut. These are top foods to avoid with mouth ulcers until pain drops.
Spicy And Salty Foods
Spicy food hits nerve endings and makes the sore throb. Salty snacks can also sting and dry the area. Skip hot sauce, chilies, strong masalas, pickles, and very salty chips. This choice alone can make home remedies for mouth ulcers feel twice as effective.
Crunchy Or Sharp Foods (Chips, Crusts)
Sharp edges reopen the sore. Chips, toast crust, hard crackers, and nuts can scrape your mouth with every bite. Choose soft rice, pasta, and soaked bread instead. This matters because repeated scraping keeps ulcers open longer. These are key foods to avoid with mouth ulcers .
Carbonated And Very Hot Beverages
Fizzy drinks can sting. Very hot tea can burn sensitive tissue and slow healing. Drink cool or warm liquids instead. Let the soup cool a little before you eat. This supports reducing mouth ulcer inflammation and lowers pain spikes.
When To See A Doctor
Ulcer Persists More Than 2 Weeks
Most canker sores improve within 1 to 2 weeks. If your sore does not heal after two weeks, you should get it checked.
Recurrent Or Very Painful Ulcers
If you keep getting ulcers several times a year, or the pain stops you from eating and sleeping, seek care. Frequent episodes are a reason to contact a medical professional.
Systemic Symptoms Or Fever
A plain canker sore should not make you feel sick. If you have fever, diarrhea, a headache, a skin rash, drooling, or trouble swallowing, you need medical advice.
Diagnostic Tests And Referral Cues
A clinician may check for triggers like iron, B12, or folate deficiency. They may also rule out infections or immune-related issues if your ulcers are severe or frequent. If you have many sores, doctors sometimes prescribe medicated rinses. Steroid rinses like dexamethasone for pain and inflammation, or lidocaine for pain control, are used in more serious cases.
Prevention Tips For Mouth Ulcers
Stress Reduction Strategies
Stress can trigger canker sores in some people, such as emotional stress, as a possible trigger. You do not need fancy routines. Protect your sleep. Take short breaks. Keep meals regular. When your body stays steady, your mouth lining often stays steadier too.
Avoid Mouth Trauma (Braces, Sharp Foods)
Cheek bites and sharp foods start many ulcers. Eat more slowly when you are tired. If braces rub, dental wax can reduce friction. If a tooth edge feels sharp, a dentist can smooth it.
Oral Care Routine And Regular Dental Checks
Brush gently, floss carefully, and replace worn brushes. Dental visits help catch rough edges, broken fillings, or appliances that keep rubbing the same spot.
Maintain Balanced Diet And Supplements If Needed
If you get ulcers often, ask a clinician about checking iron, B12, and folate. Do not guess high-dose supplements. Needs vary by age and condition. This supports mouth ulcer treatment at home because you remove hidden causes, not just the pain.
FAQs
1. What Is The Fastest Home Remedy For Mouth Ulcers?
For fast comfort, combine two steps: cool the sore with an ice chip, then coat it with honey. These home remedies for mouth ulcers can lower stinging quickly, but healing still takes days.
2. Can Mouth Ulcers Heal In One Day?
