Mouth Sores

Mouth sores can make it extremely painful to talk or even eat, whether they are canker sores, fever blisters or any other type of oral lesion. McKinney ENT Clinic professionals have the experience and expertise needed to clear up this troublesome problem for good.

Different Types of Mouth Sores

There are two main types of mouth sores; fever blisters and canker sores. Fever blisters typically show up on the lips, but they can also appear on the roof of the mouth as well as the gums. Pain may start becoming noticeable well before a fever blister occurs – by as much as a few days. These kinds of blisters usually burst within a few hours and then form a crust, then typically disappear within 7-10 days. The main cause of a fever blister is the activation of the herpes simplex virus, which can lie dormant in people for several years. Stress, hormonal changes, sun exposure and trauma are some of the reasons that fever blisters are activated. If you have a fever blister you have to be extremely careful because you could infect someone else.

Canker sores differ from fever blisters in that they are small ulcers that occur inside the cheeks and lips as well as the soft palate and tongue – not on the roof of the mouth. It is estimated that as much as 80 percent of people in the U.S. develop canker sores between the ages of 10 and 20. While canker sores can develop due to stress and trauma, they sometimes occur to due the intake of certain acidic foods as well. Unlike fever blisters, canker sores are not contagious.

Treatment of Mouth Sores

Topical agents are usually prescribed for mouth sores. Fever blisters typically respond to an ointment that contains an anti-viral substance, while canker sores can be treated through the use of a corticosteroid in many cases.
