What are the signs and symptoms of the condition?
Mouth ulcers are generally yellow or gray in color and about 3 centimeters in size. Other signs and symptoms may include the following:
pain when brushing or using mouthwash
swelling around the ulcer
A mouth ulcer is a small sore in the mucuous membranes inside the mouth.
What is going on in the body?
The mouth is sensitive to many irritations. Problems in other parts of the body can also cause sores in the mouth. Although most mouth sores will go away by themselves and are of little concern, some are much more serious.
What are the causes and risks of the condition?
There are many causes of mouth ulcers. They range from minor irritants to mouth cancer. Some of the common causes are as follows:
accidental cheek, lip, or tongue biting
accidental damage from tooth brushing
allergic reaction to medications
burns from food or drink that is too hot
burns or irritations from medications, such as aspirin
cancer of the mouth or lips
chemotherapy or radiation therapy
HIV, the virus that causes AIDS
an impacted tooth
irritation from a dental procedure
irritation from orthodontic appliances
localized irritation from a disease, such as Parkinson's disease
medications that cause mouth dryness, including antihistamines such as diphenhydramine
a new tooth coming in, known as a tooth eruption
reactions to tobacco products
serious medical illnesses that weaken the person, such as cancer
some sexually transmitted diseases, such as gonorrhea
viral disease, such as oral herpes
Women are more prone to mouth ulcers than men are,
especially during pregnancy or right before a menstrual period.
