Cold sores cause enough discomfort and stress on their own, but they can become even more of a hassle if you have a dentist appointment scheduled. Many patients worry about spreading infection or worsening symptoms, not to mention feeling embarrassed, during their visit.
Taking a moment to understand when you should and should not go to your dentist appointment with a cold sore can help reduce stress and allow you to receive the oral care you need as soon as possible.
Can You Go to the Dentist with a Cold Sore?
In many cases, you can still go to a dental visit with a cold sore. This condition comes from the herpes simplex virus type 1 (HSV-1). HSV-1 cold sores spread through direct contact, especially when the sore remains active and open. Dentists understand this condition and follow strict infection-control protocols.
Cold sore precautions your dental team will take include wearing gloves and masks, and using sterilized tools to help reduce cold sore transmission risk. However, the location and severity of the condition matter. For example, you may want to avoid the dentist with a cold sore in the blister stage.
If the cold sore is small, dry, and healing, your dentist may proceed with treatment safely. If the condition remains painful, open, oozing, or located where dental tools may irritate it, avoiding dental care may make more sense.
When You Should Reschedule a Dental Appointment for a Cold Sore
Depending on the state of the cold sore, dental work may not be advisable. Active cold sores increase the risk of spreading the virus and can worsen due to stretching or contact during treatment.
You should consider rescheduling if:
- The cold sore appears in the early blister stage
- The sore actively leaks fluid or bleeds
- You feel significant pain or swelling
- You need extensive treatment near the lips or gums
- You feel feverish or unwell
Dental procedures often require pulling on the lips or placing instruments near the corners of the mouth. These movements can reopen sores and delay healing, not to mention increase the risk of spreading, as active cold sores are contagious.
Calling your dental office ahead of time helps the team plan appropriately. Most practices appreciate advance notice and can help you choose the best time to come in. Remember that dental teams have experience with handling cold sore situations, and you shouldn’t feel embarrassed about this common issue.
When You Should Still Go to the Dentist with a Cold Sore
Some dental visits should not wait, even if you have a cold sore. Urgent dental issues require prompt care to prevent serious complications.
You should still keep your appointment if:
- You have severe tooth pain
- You show signs of infection or swelling
- You have a broken or knocked-out tooth
- You need emergency dental treatment
- The cold sore is small and already healing
In these cases, delaying care may cause more harm than the cold sore itself. Dentists can adjust treatment plans and use protective measures to keep everyone safe. Let your dentist know about the cold sore before your visit, and the team will prepare accordingly.
How to Prepare for a Dental Visit If You Have a Cold Sore

If you plan to attend your appointment with a cold sore, preparation helps reduce irritation and risk. Take the following steps before your visit:
- Start Antiviral Treatment Early: Over-the-counter antiviral creams or prescription medications can shorten healing time. Begin treatment as soon as symptoms appear.
- Avoid Touching the Sore: Touching the sore spreads the virus and delays healing. Wash your hands frequently and avoid picking at scabs.
- Keep the Area Moist: Moisture prevents cracking and bleeding, reducing healing time and discomfort. Apply a protective ointment regularly, and especially during your appointment.
- Inform the Dental Team: Call the office before your visit and explain the situation. Clear communication allows the team to schedule appropriately and use extra precautions.
- Stay Hydrated: Dry lips crack more easily. Drinking water helps keep tissues flexible and comfortable.
