Cold sores can be triggered in a number of ways, including cold weather.  If you have a cold sore and have an appointment with us to see a Dentist or Hygienist we would prefer not to treat you until the cold sore has gone away.

Active cold sores can be painful and can bleed during treatment so we strongly suggest you visit once the cold sore has disappeared.  Of course, if you have toothache and really need to see someone, there are instances where we would see you.  You just need to make us aware that you have a cold sore so we can be prepared.

What causes cold sores?

The herpes simplex virus type 1, which usually causes cold sores, is spread through forms of contact such as kissing or sharing utensils with an infected person.

Once you have been exposed to the herpes simplex virus, it will lie dormant until it is triggered. The virus can be triggered in a number of ways. These causes include;  stress and fatigue, allergies, certain foods and cold weather or excessive sunlight.

Cold sore symptoms

A burning or tingling feeling around the lips in the days before the blister erupts and a small fluid-filled blister appearing on the outside edge of the lips which then forms a crust of scab.

Cold sore treatment

Although there is no cure for the herpes simplex virus, cold sore medicine such as antiviral medications can help to heal the cold sore more quickly and reduce their frequency.

If your cold sore does not clear up within two weeks or if your symptoms are severe, you should make an appointment to see your GP who will be able to recommend a cold sore treatment.

How to prevent cold sores

It can be difficult to prevent cold sores. However, if you know what your cold sore triggers are, try to avoid them as best you can. In extreme cases, a daily prescription of antiviral medication might be recommended by your doctor.
