When to Seek Professional Advice
Recurring or very painful mouth ulcers can signal nutritional deficiencies, stress, hormonal changes or underlying medical conditions. Our pharmacy team can advise on over-the-counter pain relief, topical antiseptics and protective pastes, and can recommend supplements if a deficiency is suspected. If ulcers are accompanied by fever, weight loss, blood, or they persist beyond three weeks, you should see your GP. For immediate relief, topical anaesthetics can numb pain before meals, helping with eating and oral care while ulcers heal.

Practical Relief and Prevention Tips
Managing mouth ulcers focuses on reducing pain, protecting the sore area and addressing triggers. Use protective pastes or gels to shield the ulcer during eating, and choose gentle mouthwashes to reduce bacterial load without stinging. Identify and avoid dietary triggers like nuts, crisps, citrus or very salty snacks. Keep lips and mouth hydrated and consider a multivitamin if you have frequent outbreaks. Our pharmacists can suggest suitable OTC products and advise if prescription creams or specialist referral is needed for persistent or severe ulcers.

What causes mouth ulcers?

Can a pharmacist help?
