Cold Sores

Many people develop cold sores or so-called “fever blisters” on their lips or in their mouth.  These lesions are caused by the herpes virus, and they can easily be passed from one person to another or even to other parts of the body.  Various conditions such as drying the lips, sunburn, a high fever, or stress can cause cold sores to erupt.  The causative agent can cause cold sores to erupt.  The causative agent for these lesions stays in the body once you have had it.  Fortunately, they heal in about a week.

What can you do about cold sores?

• Topical anesthetics are available for cold sores.
• Various sealers or protectants are available.
• Topical or systemic anti-viral medications can be prescribed by your dentist, if delivered to you as soon as you feel the cold sore developing.
• Ice placed on the lesion provides some relief.
• Unfortunately, healing cannot be accelerated.

These lesions can be spread easily.  Be careful!  There is no known cure for cold sores.
