Although normally benign, a cold sore outbreak can be irritating and embarrassing. Understanding why they occur is the first step to minimizing outbreaks.
The typical cold sore (also known as a fever blister) is caused by the Herpes Simplex Virus (HSV) Type I, medically known as “Herpes Labialis” because it occurs on or around the lips. This virus is not to be confused with HSV Type II, which causes a genital infection. Unlike most viruses, HSV Type I can cause a recurring sore outbreak in certain people. Most viruses tend to occur only once because the body produces anti-bodies to prevent further attack; it’s believed HSV Type I, however, can shield itself from these defenses by hiding in the body’s nerve roots.
These cold sore outbreaks often occur during periods of high stress, overexposure to sunlight or injuries to the lip. Initially you may have an itch or slight burning around the mouth that escalates into more severe itching, redness, swelling and blistering. The sores will break out for about a week to ten days and then scab over and eventually heal (unless they become infected, in which case the healing process may go longer). You’re contagious between the first symptoms and healing, and so can spread the virus to other people.
In recent years, anti-viral prescription medications have been developed that can effectively prevent HSV outbreaks, or at least reduce the healing time after an occurrence. The most common of these are acyclovir and valcyclovir, proven effective with only a few possible mild side effects. They can be taken routinely by people with recurring cold sores to suppress regular outbreaks.
While HSV Type I cold sores are more an aggravation than a health danger, it’s still important for you to see us initially for an examination if you encounter an outbreak. It’s possible for a more serious condition to masquerade as a cold sore or blister. A visit to us may also get you on the right track to reducing the frequency of outbreaks, as well as minimizing discomfort when they do occur.

While it’s common for most of us to get an occasional cold sore, you may suffer from regular breakouts. If so, you know firsthand how uncomfortable and embarrassing they can be and seeming to erupt at the most inopportune moments.
What you’re experiencing is the result of a virus — the Herpes Simplex virus (HSV) Type I to be exact. Don’t let the name disturb you — although similar it’s different from the sexually transmitted virus known as HSV Type II. As with any virus the body responds by making and distributing antibodies to stop its attack. That’s typically the end of it but for some people the virus appears to be able to hide in the nerve roots of the mouth and elude the effects of the antibodies.
The sores associated with the virus tend to break out when a person is under stress, experiences trauma to the lip or even from sun exposure. The breakout begins with a slight itching or burning around the mouth that typically advances to more severe itching, swelling, redness and blistering. Eventually the sores will scab over and heal as the outbreak winds down. The period from breakout to final healing (during which you’ll also be contagious to others) usually lasts seven to ten days.
Although normally not a danger to health, cold sore outbreaks can be painful and irritating. In the past, most patients simply had to let the outbreak run its course with topical ointments to ease discomfort.Â In the last two decades, however, new anti-viral medication has proven effective in preventing the outbreaks in the first place or at least lessening their duration.
If you have regular bouts of cold sores prescription drugs like acyclovir or valcyclovir taken orally can help suppress the occurrences altogether, and have few side effects. Topical agents can also be used as a supplement to the drugs to help ease itching and other pain symptoms.
It’s important, though, that you undergo a complete oral examination to rule out more serious conditions associated with mouth sores. If we find that your problem is recurring cold sores, these new treatments could help you escape the cycle of discomfort.
