But some of us suffers from recurrent bouts of mouth ulcers which often have no obvious cause.
Persistent ulcers can be a sign that somewhere in your body something is not functioning as well as it should.
Conditions such as Crohn's disease, Iron deficiency anaemia and vitamin B12 deficiency anaemia can all cause lingering ulcers that won't easily heal.
The key is not what each ulcer looks like, but how long it takes to heal. Any ulcer that stays unhealed longer than three weeks need referral for investigations, as there could be an underlying medical problem.
Some things that could cause mouth ulcers are:
1. Sensitivity to chocolates and coffees.
2. Stress or Menstruation .
3. Hard toothbrush.
4. Gastrointestinal diseases.
5. Pain-reliever (Non-Steroidal Anti-Inflammatory Drugs).
6. Oral Cancer.
7. Quiting smoking.
So how do we treat them?
1. Avoid hard and acidic foods (chips and citrus fruits and vinegar)
2. Use a gel before bed (over the counter gels such as Bonjela or gel containing anaesthetics such as Lidocane
3. Take a steroid (topical corticosteroids such as hydrocortisone buccal tablets)
