canker sore

Sores in the mouth which are called Canker Sores are common in many people. Doctors or dentists often term it as Aphthous Ulcers or Aphthous Stomatitis.

These can appear on the soft palate, on your mouth, lips, or on the roof of your mouth. In most of the cases, these are not painful and non-contagious.

Aphthous Stomatitis, however, in some cases can occur frequently due to abnormal response of your immunity system to the bacteria that is present in your mouth.

These sores can cause pain but they can heal on their own. If you experience these canker sores and want to learn more about them, this article details the causes, symptoms, and treatment of canker sores.

What are Canker Sores?

Canker sores are small ulcers inside the mouth that cause pain.  These can happen on the lips and the inside lining of lips and cheek. They are generally white or yellow in color with red-bordered inflamed soft tissue.

Usually, a single ulcer shows on the inner lining of the mouth but at times they can appear in clusters.

These sores cause pain and a tingling sensation in your mouth. It causes more pain if you eat spicy, tangy, or acidic food causing difficulty in eating.

You experience a small red bump in your mouth before it bursts to reveal a sore. It causes the area around the sore to be painful for few weeks.

Canker sores are not contagious and so they cannot spread with kissing or sharing food. But they should not be mistaken with cold sores as they are contagious and can spread with these activities.
