What is a Mouth Ulcer and Why Do I Get Them?
If you’ve ever felt that sudden, sharp sting inside your mouth, you’re likely familiar with a mouth ulcer. Rest assured, you are not alone. These small, painful sores, also known as aphthous ulcers or canker sores, are an incredibly common issue that most people in Australia will experience at some point. To understand in detail what is a mouth ulcer, it’s helpful to know they are small lesions that develop on the soft tissues inside your mouth or at the base of your gums. It’s important to distinguish them from cold sores, which are caused by the herpes simplex virus, appear outside the mouth (usually on the lips), and are contagious. Mouth ulcers, on the other hand, are not contagious.
For a clear visual guide on identifying these common sores, the video below offers an excellent explanation:
Common Types of Mouth Ulcers
While they all cause discomfort, mouth ulcers can vary in size and severity. They are generally classified into three main types:
- Minor aphthous ulcers: These are the most common type, appearing as small, oval-shaped sores with a red border. They typically heal on their own within one to two weeks without scarring.
- Major aphthous ulcers: Less common, these ulcers are larger, deeper, and have more irregular edges. They can be extremely painful and may take up to six weeks to heal, sometimes leaving a scar.
- Herpetiform ulcers: This type is rare and characterised by clusters of dozens of tiny, pinpoint-sized sores that can merge into one large ulcer. Despite the name, they are not caused by the herpes virus.
Top Triggers and Causes
Understanding what causes your mouth ulcers is the first step toward prevention and effective mouth ulcer treatment. While the exact cause isn’t always clear, they are often linked to a combination of factors. The most common triggers include:
- Minor mouth injuries: An accidental cheek bite, vigorous brushing, or irritation from dental work like braces or a sharp edge on a filling can all trigger an ulcer.
- Stress and anxiety: Many people find they experience more frequent outbreaks during periods of high emotional stress, highlighting the strong connection between your mind and oral health.
- Food sensitivities: Certain foods can trigger ulcers in sensitive individuals. Common culprits include acidic fruits (lemons, pineapples), spicy foods, chocolate, and coffee.
- Nutritional deficiencies: A lack of essential vitamins and minerals, particularly vitamin B12, zinc, folic acid, or iron, can contribute to the development of mouth ulcers.
Immediate Relief: Safe and Effective Home Remedies
When a painful mouth ulcer appears, your first priority is immediate relief. While these sores typically heal on their own, managing the discomfort is crucial. The following home remedies are a safe and effective first-aid approach for minor ulcers, designed to soothe pain and create a better environment for healing. Please remember, these methods are for temporary comfort and not a substitute for professional diagnosis if ulcers are severe, recurring, or persistent.
Soothing Mouth Rinses You Can Make Today
A gentle mouth rinse can clean the area, reduce bacteria, and provide significant pain relief. These simple solutions are a cornerstone of at-home mouth ulcer treatment and can be made in moments.
- Saltwater Rinse: A time-tested remedy for a reason. Dissolve half a teaspoon of salt in one cup of warm water. Swish the solution gently in your mouth for 15-30 seconds, then spit it out. Salt helps to cleanse the ulcer and can aid the healing process.
- Baking Soda Rinse: Baking soda helps to neutralise acids in the mouth that can irritate an ulcer. Mix half a teaspoon of baking soda into one cup of warm water, and use it in the same way as the saltwater rinse. Always swish gently and do not swallow the mixture.
Dietary Adjustments for Comfort and Healing
What you eat and drink can either soothe or aggravate a mouth ulcer. Making smart dietary choices is a key step to relieve the symptoms and prevent further irritation while your mouth heals.
- Foods to Eat: Opt for soft, cool, and bland foods. Think yoghurt, smoothies, mashed potatoes, and custards.
- Foods to Avoid: Steer clear of anything that can cause a stinging sensation. This includes spicy foods (curries, hot sauce), acidic foods (tomatoes, citrus fruits, pineapple), and hard or crunchy items (toast, crisps, nuts).
- Helpful Tip: Drink cool liquids through a straw to bypass the ulcer and minimise contact and pain.
Topical Home Applications
Applying a soothing agent directly to the ulcer can provide targeted, temporary relief. This is a simple yet effective part of managing discomfort at home. When applying anything directly, ensure you use a clean cotton swab or clean fingers to prevent introducing bacteria.
- Milk of Magnesia: Dab a small amount directly onto the ulcer a few times a day. It acts as a coating, protecting the sore from irritation, and its alkaline nature helps neutralise acid.
- Ice Chips: For instant numbing relief, allow a small ice chip to dissolve slowly over the ulcer. This can temporarily reduce pain and inflammation.
Over-the-Counter Treatments: Your Pharmacy Options
While simple home remedies can provide initial comfort, your local pharmacy offers a range of effective products for more targeted relief. These over-the-counter options are designed to manage the pain and discomfort of mouth ulcers, helping you eat and speak more comfortably while the sore heals. It is important to remember that these products provide symptomatic relief; they do not treat the underlying cause. For a comprehensive overview of different mouth ulcer treatments and when to seek professional advice, trusted medical resources offer excellent guidance. Always read the product label carefully and follow the directions to ensure safe and effective use.
Numbing Gels and Pastes
These are often the first choice for immediate pain relief. Products containing a local anaesthetic, such as benzocaine or lignocaine, work by temporarily numbing the nerve endings in the affected area. This provides a welcome respite from the sharp, stinging pain. In Australia, common brands you’ll find include Bonjela and SM-33 Gel. While highly effective, remember the numbing effect is temporary and you will need to reapply the gel as directed-be careful not to exceed the recommended dose.
Protective Patches and Films
A newer form of mouth ulcer treatment involves creating a physical barrier over the sore. These small patches or liquid films adhere directly to the ulcer, forming a protective seal. This is incredibly beneficial as it shields the ulcer from irritation caused by your tongue, teeth, and food. This protection can significantly reduce pain and may help speed up the healing process. While they can sometimes be tricky to apply correctly, they often provide long-lasting relief for several hours at a time.
Antiseptic and Medicated Mouthwashes
It is crucial to distinguish these from your daily cosmetic mouthwash. Medicated mouthwashes contain active ingredients designed to promote healing and prevent the ulcer from becoming infected. Key ingredients to look for include:
- Chlorhexidine: A powerful antiseptic that reduces the amount of bacteria in your mouth, helping to keep the area clean.
- Benzydamine: An anti-inflammatory agent that can help reduce pain and swelling associated with the ulcer.
While beneficial, be aware that some antiseptic mouthwashes, particularly those with chlorhexidine, can cause temporary staining of the teeth with prolonged use. It is best to use them for the recommended duration only.
When to See a Dentist: Red Flags You Shouldn’t Ignore
While most mouth ulcers are harmless and resolve on their own, it’s important to know when to seek professional care. Viewing a dental visit as a proactive step rather than a last resort ensures your oral health is always protected. A professional evaluation is a crucial part of a safe and effective mouth ulcer treatment plan, especially when certain signs appear. At Star Dental Care, our compassionate team is here to provide clarity and gentle care when you need it most.
How Long is Too Long for an Ulcer?
The most important rule of thumb is the two-week guideline. If you have a mouth ulcer that has not shown significant signs of healing after two weeks, it’s time to book an appointment. A non-healing sore requires a professional diagnosis to rule out more serious underlying conditions and ensure you get the correct treatment. A simple dental check-up can provide the answers and peace of mind you deserve.
Concerning Symptoms to Watch For
Beyond the two-week rule, certain symptoms should prompt you to see a dentist sooner. Don’t hesitate to contact us if your mouth ulcer is accompanied by any of the following:
- The ulcer is unusually large, or you have multiple ulcers appearing at once.
- The pain is severe and cannot be managed with over-the-counter pain relief.
- You develop systemic symptoms like a fever, skin rash, or swollen lymph nodes in your neck.
- The sore extends onto your lips or is surrounded by bright red, inflamed tissue.
Recurring Ulcers and Your Overall Health
If you find yourself constantly battling new mouth ulcers, it could be a sign of more than just localised irritation. Frequent outbreaks can sometimes be linked to underlying health issues, such as nutritional deficiencies, autoimmune conditions, or gastrointestinal diseases like Crohn’s disease. Your dentist is often the first health professional to spot these patterns. By examining your oral health in a holistic context, we can help identify potential triggers and guide you toward a comprehensive management strategy. For severe pain that requires immediate attention, we offer emergency dental services to provide prompt relief.
Professional Mouth Ulcer Treatments Your Dentist Can Provide
While home remedies can provide temporary relief for an occasional ulcer, you should seek professional care for sores that are unusually large, long-lasting (more than two weeks), or frequently recurring. At Star Dental Port, we view persistent mouth ulcers not just as a nuisance, but as a condition deserving of expert diagnosis and management. Our goal is to provide lasting relief and ensure there are no underlying health concerns.
Accurate Diagnosis: Ruling Out Other Conditions
The first and most critical step in effective mouth ulcer treatment is a precise diagnosis. During your visit, our experienced dentists will conduct a thorough oral examination. We are trained to differentiate a common aphthous ulcer from other oral lesions, such as viral infections or early signs of other diseases. In the rare case that an ulcer is non-healing, a small biopsy can be taken to provide a definitive diagnosis and complete peace of mind.
Prescription Medications and Therapies
Once a diagnosis is confirmed, we can offer advanced treatments that are more potent and targeted than over-the-counter options. Our patient-centric approach ensures you receive the most appropriate care for your specific situation. These therapies include:
- Topical Corticosteroid Pastes: These prescription-strength pastes are applied directly to the ulcer. They are highly effective at reducing inflammation and pain, significantly accelerating the healing process.
- Powerful Antimicrobial Mouth Rinses: To prevent secondary infections that can delay healing and worsen pain, we can prescribe specialised mouth rinses. These help maintain a clean oral environment conducive to rapid recovery.
- Low-Level Laser Therapy: Embracing cutting-edge technology, we offer this modern, pain-free option. The gentle laser energy stimulates cellular repair, provides immediate pain relief, and can dramatically reduce the ulcer’s lifespan.
You don’t have to simply endure the discomfort of severe or chronic mouth ulcers. A professional evaluation is the fastest and safest path to relief. If you’re looking for a definitive solution, the compassionate team at Star Dental Port is here to help you smile comfortably again.
Preventing Future Mouth Ulcers: A Proactive Approach
While finding immediate relief is important, the most effective long-term mouth ulcer treatment is preventing them from forming in the first place. By adopting a proactive approach to your oral health and overall well-being, you can significantly reduce the frequency and severity of future outbreaks. Taking control starts with a few consistent, positive changes to your daily routine.
Mastering Your Oral Hygiene Routine
A gentle yet meticulous oral hygiene routine is your first line of defence. Aggressive brushing can cause tiny abrasions that may develop into ulcers. To protect your mouth’s delicate tissues:
- Use a soft-bristled toothbrush and gentle, circular motions to clean your teeth without irritating your gums.
- Choose a toothpaste free from sodium lauryl sulfate (SLS). This common foaming agent can be an irritant for some people and may trigger ulcer formation.
- Be consistent. Brushing twice and flossing once daily reduces the oral bacteria that can contribute to ulcer development.
Prevention is always better than cure. It starts with regular teeth cleaning and professional check-ups to keep your oral environment in pristine condition.
Diet and Supplements for Oral Health
Your diet plays a crucial role in your body’s ability to heal and resist ulcers. Nutritional deficiencies are a known cause, so focus on incorporating foods rich in B vitamins (especially B12), iron, and zinc, such as leafy greens, lean meats, eggs, and legumes. If you suspect certain foods trigger your ulcers (e.g., highly acidic or spicy foods), consider keeping a food diary to identify patterns. Always consult with your GP or a healthcare professional before starting any new supplements to address a potential deficiency.
Managing Stress and Lifestyle Factors
The connection between stress and your physical health is undeniable. High stress levels can weaken your immune system, leaving you more vulnerable to mouth ulcer outbreaks. Integrating simple stress-reduction techniques into your life can make a significant difference. Consider activities like mindfulness, daily walks, or gentle exercise. Prioritising a full night’s sleep is also essential, as it allows your immune system to function optimally and supports your body’s natural healing processes.
By focusing on these preventative strategies, you empower yourself to maintain not just a comfortable mouth, but a healthier life. For personalised advice on your oral health, the compassionate team at Star Dental Port is here to help you on your journey.

Frequently Asked Questions About Mouth Ulcer Treatment
How can I make a mouth ulcer heal faster?
To encourage faster healing, rinse your mouth with warm salt water several times a day and avoid spicy, acidic, or crunchy foods that can cause irritation. Over-the-counter topical gels from your local chemist can provide a protective barrier and numb the area, reducing discomfort. Maintaining excellent oral hygiene by brushing gently is also crucial. If an ulcer persists for more than two weeks, it is essential to seek professional advice to ensure proper care.
Are mouth ulcers contagious like cold sores?
No, common mouth ulcers (aphthous ulcers) are not contagious. You cannot pass them to others through kissing, sharing utensils, or drinking from the same glass. This is a key difference from cold sores, which are caused by the herpes simplex virus and are highly contagious. This distinction is important for your peace of mind; a mouth ulcer is a localised inflammation, not an infection that can be spread to your family or friends.
What is the main cause of recurring mouth ulcers?
There is not one single cause, but recurring ulcers are often linked to several factors. Common triggers include minor oral trauma from accidental bites or sharp foods, stress, and hormonal changes. Certain food sensitivities, particularly to acidic fruits or gluten, can also play a role. For some individuals, recurring ulcers may signal an underlying health issue or a nutritional deficiency, which is why persistent cases warrant a professional evaluation to determine the root cause.
Should I ever try to pop or scrape a mouth ulcer?
Absolutely not. You should never attempt to pop, scrape, or pierce a mouth ulcer. Doing so will cause significant pain, break the protective membrane, and introduce bacteria into the open wound. This dramatically increases the risk of a secondary infection and will almost certainly prolong the healing process. The best approach is to allow the ulcer to heal naturally, using gentle rinses and topical treatments to manage any discomfort safely and effectively.
What vitamin deficiency is most commonly linked to mouth ulcers?
While several deficiencies can contribute, a lack of Vitamin B12 is one of the most frequently identified culprits behind recurring mouth ulcers. Deficiencies in other B vitamins, as well as iron, zinc, and folic acid, are also common triggers. If you experience frequent ulcers, a simple blood test can help determine if a nutritional shortfall is the cause. Addressing this is a key part of an effective long-term mouth ulcer treatment plan for many patients.
Can my toothpaste be causing my mouth ulcers?
Yes, for some individuals, it can. The common foaming agent found in many toothpastes, Sodium Lauryl Sulphate (SLS), can irritate the delicate tissues inside your mouth and trigger ulcer formation. If you suffer from frequent ulcers, switching to an SLS-free toothpaste, available at most chemists and supermarkets, is a simple and often effective step. This is a highly recommended part of a holistic approach to preventing ulcer recurrence.
