Mouth ulcers

Fact Checked

Mouth ulcers are considered common and irritating for most individuals. These are characterized as open sores with whitish appearance with a reddened inflamed border that causes pain. Take note that mouth ulcers usually develop on the inside of the lips, cheeks, on the floor of the mouth and under the tongue.

The ulcers can be caused by foods, constipation, hormonal changes, excess acidity, hereditary factors, accidentally biting the cheek, stress and deficiency in Vitamin B complex, vitamin C, iron and other nutrients.

A mouth ulcer is not a dangerous condition and heals within 7- 10 days. As for herpetiform ulcers, they take a longer time to heal. Major ulcers are deeper and 10 mm in diameter in size. In addition, herpetiform ulcers form in clusters of a large number of small ulcers.
