Mouth ulcers, also known as canker sores, are small, painful lesions that form on the soft tissues inside your mouth, such as your cheeks, tongue, gums, or lips. While they’re common and usually harmless, recurring or severe ulcers can make eating, drinking, and even talking uncomfortable.
The good news is that most mouth ulcers heal on their own with time, but that doesn’t mean you have to wait it out. There are safe and effective ways to relieve the discomfort and speed up healing. We look at what causes mouth ulcers, how to treat them, and which products are most effective for reducing pain and preventing future outbreaks.

What Causes Mouth Ulcers?
There are a few common triggers behind mouth ulcers:
Irritation or trauma: Accidentally biting your cheek or tongue, brushing too hard, or irritation from braces, retainers, or dentures can cause ulcers to form.
Stress and fatigue: Physical or emotional stress has been linked to recurring mouth ulcers in both adults and children.
Vitamin deficiencies: Low levels of nutrients like iron, vitamin B12, or folate can contribute to frequent or stubborn ulcers.
Food sensitivities or allergies: Certain foods—especially spicy, acidic, or salty items—can trigger or worsen ulcers in some people.
Medical conditions: Chronic illnesses like coeliac disease, inflammatory bowel disease, or autoimmune conditions can cause persistent or multiple ulcers.
How to Treat and Prevent Mouth Ulcers
The best approach to managing mouth ulcers is a combination of symptom relief and prevention. Here are some steps you can take:
Use an alcohol-free mouthwash: A gentle mouthwash can help keep the area clean and reduce bacteria without stinging or causing irritation.
Avoid irritating foods: Spicy, citrusy, and salty foods can aggravate ulcers and delay healing. Stick to bland, soft foods until the area heals.
Apply a topical gel or patch: Mouth ulcer gels and protective pastes form a soothing barrier over the sore, shielding it from friction and helping reduce pain.
Switch to a soft-bristled toothbrush: Brushing gently with a soft toothbrush prevents further trauma and helps keep your mouth clean.
Consider SLS-free toothpaste: Toothpastes without sodium lauryl sulfate (SLS) are less likely to irritate your mouth and may reduce ulcer recurrence.
Stay well-nourished and hydrated: A healthy diet and plenty of water support your body’s natural healing process.
