What Is a Canker Sore

Canker sores are small ulcers that appear inside your mouth. You may notice them on your cheeks, lips, tongue, or gums.

They are not contagious and usually show up as round or oval sores with a white or yellow center and a red border. These sores can feel painful, especially when eating spicy or acidic foods.

Common causes include stress, minor injuries like biting your cheek, certain foods, or a weakened immune system. Most canker sores heal on their own within one to two weeks.

What Is a Cold Sore

Cold sores are different because they are caused by a virus. They usually appear on the outside of the mouth, often around the lips.

They often start with a tingling or burning feeling, followed by small fluid-filled blisters. These blisters can break, form a crust, and then heal over time.

Cold sores are contagious, especially when you have an active cold sore. They can spread through close contact like sharing utensils, drinks, or even a simple kiss.

Key Differences You Should Know

Understanding a few clear differences can help you identify what you are dealing with.

Canker sores appear inside the mouth and are not contagious. Cold sores usually appear outside the mouth and can spread to others.

Canker sores often come from irritation or internal factors like stress. Cold sores are linked to a viral infection that can stay in your body and return later.

Pain levels can also differ. While both can be uncomfortable, cold sores may come with additional symptoms like swelling or a burning sensation before they appear.

How to Treat Canker Sores Quickly

Most canker sores heal without special treatment, but a few simple steps can help reduce discomfort.

Rinsing your mouth with salt water can help keep the area clean. Avoiding spicy or acidic foods can prevent irritation while the sore heals.

Over-the-counter gels or mouth rinses can also help reduce pain. Keeping your mouth clean and staying hydrated supports faster healing.

How to Treat Cold Sores Fast

Cold sores need a slightly different approach because they are caused by a virus.

Antiviral creams or medications can help reduce healing time, especially if used early. Keeping the area clean and avoiding touching the sore helps prevent spreading.

It is important to avoid close contact with others while you have an active cold sore. This helps protect family members and people around you.

When Should You See a Dentist

Most sores go away on their own, but some situations need attention.

If a sore lasts longer than two weeks, becomes very painful, or keeps coming back often, it is a good idea to get it checked. A dentist can help identify the cause and suggest the right treatment.

Patients in Falls Church often visit their dental office when sores interfere with eating, speaking, or daily comfort.
