94% of the general population has the oral type of herpes which causes
"cold sores" on the
outside of the lips during stress
or physical illness. Contrary to popular belief, canker sores, which
appear inside the mouth, tongue
or palate, are not caused by the herpes virus. Canker sores are
hypersensitivity reactions to local
injury or certain foods. Herpes can occur on the soft palate and looks
suspiciously similar to canker
sore with the exception of a red halo around the white ulcer.
Genital Herpes virus is sexually transmitted and is characterized by recurring
ulcers on
the genitals lasting about one
week. The frequency of recurrence decreases with time until in many
cases a spontaneous cure takes
place. Frequent recurrences require therapy with maintenance
suppressive medications taken daily
for up to 2 years.
Both types of Herpes viruses may occur in locations other than the mouth
or genitals.
The most serious being in or around
the eye. Herpes keratitis is the infection of the cornea, which
if not treated early and aggressively,
can lead to blindness. It is critical to keep your hands away
from your face or eyes during outbreaks
of oral or genital herpes.
Canker sores are treated with a topical steroid preparation in a dental paste.
