Mouth ulcers are painful and typically small lesions that develop within the mouth. There are no definite causes of mouth ulcers, but some injuries, allergies, or sensitivities may trigger them. Mouth ulcers are common and should clear up on their own within a week or two. See a GP or dentist if you have a mouth ulcer that lasts longer than 3 weeks.
Symptoms of mouth ulcers may vary, but they typically include:
- Painful sores that may be yellow, white, or red
- Areas of redness surrounding the sores
- Pain that worsens when you eat, drink, or talk
You may have more than one mouth ulcer at the same time.
Mouth ulcers are not usually contagious unless they’re caused by an infection such as hand, foot, and mouth disease.
Most of the time, mouth ulcers heal on their own without treatment within a week. There are also over-the-counter treatments available that may decrease discomfort and healing time. These include:
- Using an antimicrobial mouthwash
- Covering the ulcer with topical pastes
- Using a numbing anaesthetic mouth spray
