Cold sores, also known as fever blisters, are a common concern. While the herpes simplex virus (HSV-1) that causes it isn’t curable, there are effective ways to manage and even prevent outbreaks.

The Basics of Cold Sores:

• Transmission: The HSV-1 virus spreads through direct contact with infected skin or saliva.
• Initial Infection: Childhood infections may cause fever, mouth discomfort, and swollen lymph nodes. The virus then lies dormant in nerve cells near the infected area.
• Triggers for Recurrence: Though not fully understood, stress, dental work, illness, lip injury, and sun exposure can trigger outbreaks in some individuals.

Common Symptoms:

• Tingling or burning around the mouth
• Fever and sore throat in some cases
• Swollen lymph nodes

Preventing and Managing Outbreaks:

• Talk to your dentist: They can prescribe medications to shorten healing time and reduce discomfort. These medications won’t eliminate the virus but may suppress outbreaks or lessen their severity.
• Reduce triggers: Manage stress, protect your lips from sun exposure with SPF, and avoid touching your face with unwashed hands.
• Topical Treatments: Antiviral creams and ointments can help shorten the duration and size of outbreaks.

By understanding cold sores and working with your dentist, you can minimize their impact and maintain optimal oral health.
