What Is The Difference Between Canker Sores And Cold Sores?

Canker Sore vs Cold Sore

Canker sores and cold sores are often used interchangeably. However, these two sores are not the same.

Being aware which type of sore you have is vital to figure out what type of treatment you need. Fortunately, there are several ways to identify which type of sore you have through based on your symptoms.

Cold Sore Symptoms include:

  • Swollen glands
  • Red, blister-like sore often with a scab or scaly appearance
  • Pain on the affected area or around the mouth
  • Clear, leaky fluid that comes from the sore
  • Sore throat
  • Fever

Canker Sore Symptoms:

  • Swollen glands
  • An open ulcer or a painful sore; may contain pits or “holes”
  • Whitish or yellowish in color with a red rim
  • Fever

It matters to know that the greatest difference between a cold sore and a canker sore is what they look like and where they are on the body. A canker sore is typically white or yellow in color while a cold sore is commonly red and at times leaks a clear fluid.

Canker sores are common within the mouth, often within the cheeks, while cold sores frequently occur on or near the outter lips.

Both types of sores may cause a fever. However, canker sores only cause fever, swollen glands, and/or fatigue in serious cases.


Treatment Options for Canker Sores and Cold Sores

There are a lot of over-the-counter medications for canker sores to relieve the pain and heal the sore. The medications usually come in the form of ointments or gels which can be directly placed on the affected area. Oral rinses are available as well. You can also try home remedies like rinsing with peroxide or salt water to clean sterilize the sore.

Meanwhile, for cold sores, you can buy topical creams and ointments which can also be bought over the counter. But, when cold sores are severe and extremely painful, doctors may prescribe pills or stronger ointment; at times they may also require medical attention and may take a long period to heal.

Cold sores can reoccur due to the herpes simplex virus. To prevent them from recurring often, seek medical attention.
