Symptoms and Causes of Mouth Sores

Now that we have mentioned the different types of sores that can appear in your mouth, we would like to go into the details of what actually causes them and how you can identify them.

Canker sores are usually painful they last from 5 to 10 days and do not present fever symptoms, they also tend to re-appear. The real cause of canker sores is still a mystery. It has been observed that many factors contribute to their development; factors such as poor nutrition, certain types of medications, bacteria, viruses, mouth trauma, sleep deprivation, sudden drop in weight and even certain foods such as citrus, potatoes, coffee, cheese nuts and chocolate can all cause canker sores.

Canker sores are very common; in fact, about 20% of people in the United States will experience canker sores during their lifetime, with women tending to experience them more often than men. Canker sores cannot be transmitted to others.

Cold sores which are sometimes associated with cold symptoms, they are usually painful and will normally disappear within one week. Cold sores will often reappear in the same locations. They are caused by the virus herpes simplex type 1 and are contagious from the time the blister ruptures to the time it is completely healed.

This type of virus can spread to other people as well as other body parts such as the genitals or the eyes. The first time a person is in contact with this type of infection is usually before adulthood and the symptoms are similar to those of a cold or flu.

Once the person acquires this virus it will remain dormant within the body, however under stressful conditions like fever, hormonal changes, trauma or exposure to sunlight they can be reactivated.
