Cold sore are viral: This is very important to know. Cold sores are a virus and are very contagious.They can easily be spread to other people and other areas of your own body. Try to not touch or pick them. Your dentist can prescribe medications to shorten the time they are present and even lessen the chance that they will reappear. Remember that the virus can not be killed, so when the sore goes away it's still alive.

Near the end..: If you have cold sores that have crusted over...Then they are on their way out. The cycle is generally about 14 days. Hang in there and don't pick at em or put anything on them.
