Is It Safe to See the Dentist If You Have a Cold Sore?

26 / 01 / 2026

Cold sores are very common and are caused by the herpes simplex virus (HSV-1). They usually appear as small, fluid-filled blisters around the lips or mouth. If you develop a cold sore close to your dental appointment, you might be unsure whether it’s still safe to attend. At Abbey Mead Dental & Implant Clinic, your wellbeing — and the safety of our team and patients — is always our top priority. Here’s what you need to know.

Is It Safe to See the Dentist If You Have a Cold Sore?

Cold sores are very common and are caused by the herpes simplex virus (HSV-1). They usually appear as small, fluid-filled blisters around the lips or mouth. If you develop a cold sore close to your dental appointment, you might be unsure whether it’s still safe to attend. At Abbey Mead Dental & Implant Clinic, your wellbeing — and the safety of our team and patients — is always our top priority. Here’s what you need to know.

Understanding Cold Sores

Cold sores often begin with a tingling or burning sensation on before a blister forms. The blister may burst, ooze, scab over, and then heal over time. Cold sores are contagious, especially during the early stages when they are open or weeping.

Key things to know:

  • Cold sores are most contagious during the first 2–3 days
  • The virus can spread to other areas of the face or to other people
  • Active cold sores may interfere with dental treatment

When You Should Postpone Your Appointment

If your cold sore is new, open, or actively weeping, we usually recommend postponing routine dental appointments. Attending at this stage can increase the risk of:

  • Spreading the virus to dental staff or other patients
  • Causing discomfort or complications during treatment
  • Accidentally transferring the infection to sensitive areas, such as the eyes

TOP TIP

If your appointment is non-urgent, waiting until your cold sore has healed helps keep everyone safe and comfortable.

When It May Be Safe to Attend

You may still be able to attend your appointment if:

  1. The cold sore is only in the early tingling stage
  2. It has dried and formed a scab
  3. You have urgent dental concerns, such as pain, swelling, or a broken tooth

In these situations, please contact us before your visit. Our team will carry out a risk assessment and take any necessary precautions to ensure safe treatment.

What to Do Before Your Appointment

  1. Call the clinic as soon as you notice a cold sore
  2. Avoid touching the sore, and wash your hands thoroughly if you do
  3. Let us know if your appointment is urgent
  4. Follow our advice about rescheduling or additional safety measures

Why Abbey Mead Dental & Implant Clinic Takes Cold Sores Seriously

Because dental treatments involve close contact with the mouth and lips, extra care is essential. Managing appointments appropriately helps protect:

  1. You, by reducing discomfort and potential complications
  2. Our dental team, by minimising exposure to the virus
  3. Other patients, by preventing the spread of infection

We truly appreciate your understanding and cooperation.
