A mouth ulcer is a small round wound in the mouth.
It often appears as a grayish yellow base surrounded by a red circle of swollen
tissue. Mouth ulcers often make eating and talking uncomfortable. Mouth ulcers
that keep coming back may be linked with digestive or immune system problems.
Mouth ulcers are usually caused by:
- Local injury (e.g. biting the inside of cheeks
or lips, or injury caused by tooth-brushing)
- Lack of certain nutrients such as iron,
folate, or vitamin B12
- Stress or hormonal changes
What
you can do
In most cases, mouth ulcers should recover after a
few days. However, the following can help:
- Avoid spicy or acidic foods that may irritate
the ulcer
- Use salt water or antiseptic gargles
When
to see a doctor
- If symptoms do not improve after 7 days of treatment
with topical medicines
- If you do not use any medicines and the mouth ulcer
does not heal within 14 days
- If the symptoms worsen during self-treatment
- If you have fever, rash, or swelling
- If you have mouth ulcers very often
How to prevent mouth ulcers
- Increase the intake of nutrients like iron, folate or vitamin B,
through food or supplements
- Do
relaxation exercises to reduce stress
- Avoid food
that have sharp edges like potato chips that may cause injury to your mouth
- Go for
