Cold Sores

What are cold sores?

Cold sores are the consequence of a viral infection, normally in childhood. They usually appear on the lips and nostrils but can be more widespread.

How do you catch cold sores?

You can catch cold sores by:

  • Directly touching a cold sore
  • Kissing someone with a cold sore
  • Sharing household objects such as towels, cups and cutlery

What Are The Symptoms?

  • The first signs are usually tingling, burning or itching.
  • Within 24 hours painful blisters form. Blisters breakdown into shallow ulcers after a few days.
  • Cold sores are infectious from the early tingling stage up to the end of the ulcer phase.

Healing is normally complete in 10 to 14 days. In children cold sores can become infected with bacteria and develop impetigo.


Why do they keep coming back?

After the first infection, the virus lies dormant in the nerve that supplies the infected area.

The virus can be reactivated at any time and cause another cold sore.

Various trigger factors are:

  • Stress
  • Fatigue
  • Strong sunlight
  • UV light from sun beds
  • Menstruation or pregnancy
  • Generally when feeling run-down

Our Advice

If you have a cold sore, wash your hands thoroughly if you accidentally touch it.

Do not:

  • Touch the cold Sore
  • Touch your eyes during the infection
  • Kiss (especially children) when you have the infection
  • Pick the ulcers or the scab. You will infect your fingers with the virus
  • Share eating/drinking utensils with others, especially children
  • Share the same towels or face cloths with others in your family
  • Consider rescheduling your dental appointment when a cold sore is present if non urgent as it may cause discomfort during treatment

What Our Patients Say About Us


  • We had a wonderful first visit to El Nashar yesterday. What a gem of a surgery! From start to finish our visit was impeccable. All the staff are clearly super happy in their work and made us feel so welcome. We had a smooth and informative check in from the lovely reception team then an outstanding check up by our dentist, Mark and his dental nurse. Mark put us all at ease immediately. He talked us through every step, took an X-ray which he then ran through and discussed any follow up treatment. He gave the children a thorough and fun examination and explained the progress they are making while at the same time finding out about them and keeping them relaxed. The surgery is impeccably clean and attractive with a lovely Egyptian theme throughout which my 10 year old really appreciated. Even the payment process was a joy thanks to Tiffany who talked me through their excellent dental plan with such attention to detail and literally the biggest smile! The team really go over and above to make your visit a positive one, Tiffany even noticed my cold sore and recommended a treatment for me! We are already looking forward to our next visit and couldn’t recommend the team more highly.
