Overview

Mouth ulcers, also known as canker sores, are minor sore spots that occur on the mucous membranes or inside of the mouth. While they usually heal naturally within a week or two, they can cause discomfort and disrupt eating and speaking during that time. Around 1 in 5 Australians experience recurrent mouth ulcers. Let’s explore several natural home remedies for mouth ulcers that help alleviate symptoms and promote healing, but remember to consult a online doctor if symptoms persist. There are supportive measures that may help manage discomfort while the ulcer heals.

Note: This information is for educational purposes only. You should consult a doctor or medical practitioner before attempting home remedies to ensure they are safe for your specific condition.

Causes

Mouth ulcers often occur without warning, but several common triggers can include:

• Lifestyle factors – stress, anxiety, or hormonal fluctuations (like pregnancy, menstrual cycles, or menopause).
• Injuries or irritation – accidentally biting your cheek, dental braces, dentures, or burns from consuming hot beverages.
• Dietary triggers – consuming acidic or spicy foods, citrus fruits, or very hot meals.
• Health conditions – deficiencies in vitamins (like B12, iron, folate), coeliac disease, Crohn’s disease, or certain medications.
• Products – using harsh toothpastes or mouthwashes that contain sodium lauryl sulphate, or having food allergies.

Symptoms

Mouth ulcers can vary in size and severity, but they usually share some standard features. Typical symptoms include:

• Small, round, or oval sores inside the mouth — often on the tongue, inner cheeks, gums, or lips
• White, yellow, or grey centres surrounded by a red, inflamed border
• Burning or tingling sensation before the ulcer appears
• Pain or discomfort when eating, drinking, or speaking
• Swelling or tenderness in the affected area
• Increased sensitivity to spicy, salty, or acidic foods

Natural remedies

Most mouth ulcers resolve on their own, but these natural remedies may help alleviate pain and promote healing.

1. Topical applications

• Honey – apply a small amount of raw honey for its antibacterial and soothing properties.
• Aloe vera gel – gently apply pure gel to soothe irritation.
• Coconut oil – both antibacterial and soothing when directly applied to the ulcer.
• Baking soda mixture – combine with water and apply to the ulcer to lower acidity.

2. Herbal mouth rinses

• Saltwater rinse – mix 1 tsp of salt in warm water and swish it around your mouth several times a day.
• Chamomile tea – cool the tea and use it as a rinse to alleviate pain and swelling.
• Green tea – contains antioxidants that may help decrease inflammation.
• Turmeric paste – create a paste with turmeric and water, and apply gently.

Can you put a tea bag on a mouth ulcer?

Yes, especially a chamomile or black tea bag. Both contain tannins that can soothe inflammation and have slight antibacterial effects.

How to use it:

1. Steep the tea bag in hot water.
2. Let it cool (don’t skip this!).
3. Place the bag gently on the ulcer for 5–10 minutes.

It won’t work magic, but it can offer some relief and support healing.

3. Peppermint oil

Peppermint oil may offer mild relief for mouth ulcers due to its cooling and antimicrobial properties, but it’s not a cure. When diluted and applied carefully, it can help ease discomfort, though it’s not suitable for everyone especially those with allergies or during pregnancy.

Is peppermint good for mouth ulcers?

Peppermint has long been celebrated in folk medicine for its cooling, numbing, and mildly antiseptic properties. It contains menthol, a compound known for its soothing effects on irritated tissues and its ability to slightly numb pain receptors.

While there’s limited direct scientific research linking peppermint specifically to healing mouth ulcers, its antimicrobial and anti-inflammatory qualities make it a potentially helpful adjunct management—especially when ulcers are caused or aggravated by bacterial overgrowth or minor trauma. Think of it as your backup dancer—not the star of the show, but still very much part of the act.

How to use peppermint oil for mouth ulcers?

If you’re keen to try peppermint oil, here’s a simple, safe approach:

• Dilute first: Essential oils are potent. Mix one drop of peppermint oil with a teaspoon of a carrier oil (like coconut or olive oil).
• Spot-apply: Using a cotton swab, gently dab the diluted oil onto the ulcer. Avoid swallowing it.
• Rinse technique: You can also add a drop to a glass of warm water and swish it around like mouthwash—then spit it out.

Expert doctor comments

“A medical practitioner may suggest using such measures once or twice daily, following a clinical assessment.”

Important considerations

Now, before you go turning your bathroom into a minty apothecary, a few words of caution:

• Don’t overuse essential oils. They can be irritating if used too frequently or without dilution.
• Don’t apply directly to broken skin without proper dilution.
• Always opt for food-grade or high-quality oils if you’re using them orally.

What if I’m allergic to peppermint?

If you’ve had allergic reactions to menthol, peppermint tea, or peppermint-flavoured toothpaste in the past—skip it. Symptoms of a peppermint allergy can include itching, swelling, or worsening of mouth ulcers.

In such cases, safer bets include saltwater rinses, chamomile, or over-the-counter gels made specifically for mouth ulcers.

What about during pregnancy?

Pregnant individuals should be cautious with essential oils in general. While peppermint oil is often considered relatively safe in small amounts, it can sometimes trigger uterine contractions or exacerbate heartburn.

Before using any essential oil during pregnancy especially orally consult your doctor or midwife.

4. Nutritional advice and supplements

• Increase your intake of vitamin B12-rich foods like eggs, dairy products, fish, or meat.
• Consider including probiotics (such as yogurt and kefir) to boost gut and immune system health.

5. Lifestyle suggestions

• Stay away from irritating foods until the ulcer is healed.
• Incorporate stress management techniques (like deep breathing, yoga, or mindfulness) into your routine.
• Ensure you get adequate rest to assist your body’s recovery.

Safety reminder: Always dilute essential oils like tea tree or clove before application, and refrain from swallowing them.

What foods make mouth ulcers worse?

If you currently have an ulcer, certain foods and beverages can aggravate the pain and prolong healing:

• Spicy dishes or foods high in chilli
• Citrus fruits such as oranges, lemons, or pineapples
• Salty snacks (like chips)
• Very hot tea or coffee
• Alcohol and tobacco

Opt for soft, cool foods such as yogurt, smoothies, or soups until the ulcer fully heals.

How to manage mouth ulcers that keep coming back?

If mouth ulcers are your frequent, unwelcome guests, you might need a more strategic approach:

• Review your diet: Are you getting enough B12, folate, and iron?
• Check for allergies: Sometimes ingredients in toothpaste or foods can be culprits.
• Reduce stress: Easier said than done, but mindfulness, exercise, or therapy can help.
• Consult your dentist or doctor: You might need tests to rule out underlying conditions.

When to consult a doctor

Most mouth ulcers are harmless and heal naturally, but if they persist, recur frequently, or cause severe discomfort, it’s best to consult a healthcare professional.

Seek medical advice if you notice any of the following:

• Ulcers lasting longer than two weeks
• Severe pain that interferes with eating, drinking, or speaking
• Frequent recurrences or multiple ulcers appearing at once
• Accompanying symptoms such as fever, rash, swollen lymph nodes, or fatigue
• White or red patches that don’t heal, as these may require further investigation
• You have an impaired immune system

Note: If you experience severe, worsening, or life-threatening symptoms, such as difficulty breathing or swallowing, call 000 immediately or attend your nearest Emergency Department (ED).

How Hola Health can help

Through Hola Health’s online telehealth consultations, you can conveniently access care from home. Our Australian-registered doctors or medical practitioners can:

• Assess your mouth ulcers and identify possible causes.
• Assess your symptoms and provide management options (if clinically appropriate).
• Provide a online sick certificate (if clinically appropriate).
• Arrange referrals for further tests or specialist care if ulcers are recurrent or linked to other health issues.

Hola Health offers affordable telehealth appointments, available Australia-wide — including bulk-billed* services for eligible patients. You can get trusted medical advice, management, and prescriptions access care within a few minutes.

Telehealth may not be suitable for every condition. Some patients with mouth lesions may require an in-person physical examination, testing, or a biopsy that cannot be performed via video.

Questions to ask your doctor

Whether online or in person, here are some questions worth bringing up:

• What might be causing my recurring ulcers?
• Could it be linked to my diet, stress, or a medical condition?
• Do I need blood tests or a biopsy, if so, will I get an online doctor referral?
• What’s the best management for pain relief?
• Are there any prescription options I should consider?

Conclusion

Mouth ulcers can be bothersome yet are generally harmless. Natural remedies, such as honey, aloe vera, and saltwater rinses, may provide relief while the wound heals. If ulcers are recurrent or particularly painful, a healthcare provider (including those available through telehealth) can investigate underlying issues and recommend management.
