What is difference between cold sores and canker sores?

Cold sores and canker sores are both common oral lesions, but they have different causes and symptoms.

Cold Sores

* Caused by the herpes simplex virus type 1 (HSV-1)

* Contagious

* Typically appear on the lips, around the mouth, or on the nose

* Start as small, red bumps that develop into blisters

* Blisters break and form a crust that can last for several days

* Can be painful and itchy

Canker Sores

* Caused by a variety of factors, including stress, hormonal changes, and certain foods

* Not contagious

* Typically appear inside the mouth, on the tongue, or on the gums

* Start as small, white or yellow sores

* Sores can be painful, but they are not usually itchy

Cold sores and canker sores can both be treated with over-the-counter medications to relieve pain and discomfort. In some cases, prescription medications may be necessary to treat severe outbreaks of cold sores.

Preventing Cold Sores and Canker Sores

There is no cure for cold sores or canker sores, but there are things you can do to prevent them from occurring.

* Cold Sores: Avoid contact with people who have cold sores. Practice good oral hygiene, and use a lip balm with sunscreen to protect your lips from the sun.

* Canker Sores: Avoid foods that trigger your canker sores. Practice good oral hygiene, and use a soft toothbrush to avoid irritating your gums.

If you experience frequent outbreaks of cold sores or canker sores, talk to your doctor. They can recommend additional treatment options to help you manage your symptoms.
