How to Get Rid of a Canker Sore: What Really Helps

Canker sores are small, round ulcers that appear inside the mouth. They can show up on the inside of your lips, cheeks, or even on your tongue. Many people want to know how to get rid of a canker sore quickly because these spots can be painful, especially when eating or talking. While a canker sore usually heals on its own, there are ways to feel more comfortable and support healing.

What Is a Canker Sore?

A canker sore, also called an aphthous ulcer, is not the same as a cold sore. Canker sores develop inside the mouth, while cold sores usually appear outside the mouth (often on the lips) and are caused by a virus. The exact cause of canker sores is not always clear, but they are not contagious and often appear when the mouth is irritated or stressed.

How Do You Get a Canker Sore?

Canker sores can develop for a few reasons. Some common triggers include biting your cheek, irritation from braces or dental appliances, stress, certain foods (like citrus or spicy foods), and sometimes even minor injuries when brushing teeth. Sometimes canker sores happen more often in families, so genetics can play a role too. Some people notice they get more when they are tired or run down. If you get frequent or unusually large canker sores, it is a good idea to discuss this with your dentist.

How to Get Rid of a Canker Sore: What Helps?

If you are dealing with a canker sore, you are probably looking for relief. While most canker sores heal on their own within a week or two, there are some things you can do to support your mouth and feel better in the meantime. Here are some general tips:

• Rinse with salt water: Swishing a mild salt water solution can help keep the sore clean and may offer some comfort.
• Avoid irritating foods: Stay away from spicy, acidic, or rough foods that could make the pain worse.
• Maintain good oral hygiene: Keep your mouth clean, but be gentle when brushing near the sore.
• Use over-the-counter topical products: There are gels and ointments available that can be applied directly to the sore to help with discomfort. Ask your dentist if you are unsure which product may be right for you.

If the sore is causing significant pain, or if it is not healing after two weeks, you should talk with your dentist. At Sullivan Family Dental in Walla Walla, we help patients of all ages manage mouth discomfort and keep their smiles healthy.

Can You Get Rid of a Canker Sore in 24 Hours?

Many people search for how to get rid of a canker sore in 24 hours, but the reality is that canker sores usually take several days to heal. No home remedy or treatment can make a canker sore disappear instantly. However, using the tips above can help reduce irritation and support your mouth while the sore heals. If you have a canker sore on your tongue or another sensitive spot, extra care with eating and oral care can make a big difference in your comfort.

When Should You See a Dentist for a Canker Sore?

Most canker sores are minor and heal on their own, but some signs mean it is time to get checked. You should contact your dentist if:

• The sore lasts longer than two weeks
• You have unusually large sores or many sores at once
• You notice severe pain, fever, or difficulty eating and drinking
• There are signs of infection, like spreading redness or pus

An exam is the best way to know what is causing a sore and how to treat it. Sometimes, what looks like a canker sore could be something else, so it is always best to ask your dentist if you are not sure.

How Does a Dentist Help with Canker Sore Treatment?

Your dentist may recommend medications or treatments if over-the-counter care does not work. This could include prescription mouth rinses or topical medications. For recurring or severe sores, your dentist may look for underlying causes, such as irritation from dental appliances or an underlying health condition. At Sullivan Family Dental, we are here to answer your questions and suggest options that fit your needs. Your comfort and health are our top priorities.
