Mouth ulcers are really common and can be uncomfortable and painful.

Mouth ulcers should clear up on their own within 2 weeks and they need time to heal, there isn't a quick fix.

Patients can have multiple mouth ulcers at a time and they can appear inside the lips, on the cheek or on/under the tongue.

Mouth ulcers can be triggered by things such as:-

• Hormonal changes
• Genetics
• Long term conditions
• B12 or iron deficiency
• Medications
• Stopping Smoking
• Feeling tired, stressed or anxious
• Cuts or burns from eating hard food or hot drinks
• A food intolerance/allergy
• Badly fitting dentures or braces
• Broken teeth
• Biting the inside of your cheek
