What is the difference between a cold sore and a canker sore?

While people often use the names for these two types of dental annoyances interchangeably, canker sores and cold sores are actually quite different. 

Canker Sores

Canker sores develop inside the mouth, most commonly on the sensitive areas of the cheeks and inner lips. Unfortunately, no one knows exactly what triggers these painful sores, and they tend to periodically pop up again and again after their first appearance. 

Cold sores have a pale white border with a small red or pink center. Many patients complain of canker sores after eating large amounts of acidic foods, such as pineapple and oranges, or after consuming a lot of sugar. Canker sores will typically remain painful for several days before beginning to heal on their own.

Cold Sores

Cold sores, on the other hand, are painful blisters typically found near the mouth. A viral infection, known as herpes simplex virus, or “HSV,” causes cold sores. These blisters are typically more irritating and more serious than canker sores, and an infected individual may experience cold sore flare-ups for the rest of their life.

Meet With Your Oswego Dentist

Thankfully, both of these conditions are manageable, and the symptoms will eventually subside on their own. If you’re experiencing a particularly painful canker sore or cold sore in Montgomery, IL, however, it’s best to have a dentist take a look and recommend any potential remedies that can help.
