at Dental Associates of Corona would like to provide you with an overview of both canker and cold sores so you can better identify what you may be struggling with when you have a painful spot in or around your mouth.

What is a Canker Sore?

Canker sores are usually smaller than cold sores and occur on the inside of the mouth. Also known as alphthous ulcers, these bumps or lesions can be extremely painful. It is not uncommon for a stubborn canker sore to last for up to two weeks, making it difficult to eat and even talk. Areas where canker sores are most often spotted include the tongue, soft palate, inner lips, inside the cheeks, or on the floor of the mouth. Canker sores are not thought to be contagious, though they are believed to be similar to cold sores in that they can be recurring and chronic in people that struggle with them. They also are seen to flare up more when stress is high. Some people find that they get canker sores as a reaction to certain acidic foods.

What is a Cold Sore?

The herpes simplex type 1 virus is responsible for cold sores. This means that the ulcers are contagious, so if you are prone to cold sores, you should avoid kissing and other such contact when you have an open sore, or even if you feel one coming on. People with cold sores often feel a tingling right before the ulcer makes its unpleasant appearance. A cold sore will usually break out around your lips, but on the outside of your mouth, making them frustrating from a physical standpoint. People that have cold sores most likely contracted the virus in childhood. The good news is that outbreaks are generally few and far between throughout your life. Also known as fever blisters, it is believe that stress or trauma can be catalysts to a breakout.
