Canker Sore on Tongue: Causes, Relief, and When to Call a Dentist

It can be frustrating to find a canker sore on your tongue. These small, painful spots can make eating, drinking, and even talking uncomfortable. If you are dealing with a sore spot in your mouth, you might wonder what causes it and how to find relief. At Sullivan Family Dental, we help patients in the Walla Walla area understand these common mouth sores and what to do next.

What Is a Canker Sore?

A canker sore is a small, shallow ulcer that develops inside the mouth. Unlike cold sores, which appear outside the mouth and are caused by a virus, canker sores are not contagious. They commonly appear on the inside of the cheeks, on the lips, on the gums, and especially on the tongue. You might also hear them called aphthous ulcers.

Common Causes of a Canker Sore on the Tongue

There are several possible canker sore causes. Some people are more prone to them than others. While the exact cause is still not completely understood, certain triggers are known to increase your risk. These include:

• Minor injuries from biting your tongue or irritation from dental work
• Stress or lack of sleep
• Eating acidic or spicy foods
• Vitamin deficiencies, like vitamin B12, iron, or folate
• Hormonal changes
• Medical conditions that affect your immune system

Sometimes, canker sores can appear for no obvious reason. If you notice sores appearing frequently or lasting longer than usual, talk to your dentist to rule out other causes.

Where Can Canker Sores Appear?

While a canker sore on the tongue is common, these sores can also develop in other areas inside your mouth. Many people get a canker sore on the gum, inside the lips, or even a canker sore on the roof of the mouth. No matter where they occur, they usually look like round, whitish or yellowish spots with a red border.

How Long Does a Canker Sore Last?

Most canker sores on the tongue heal on their own within a week or two. The discomfort usually fades as the sore gets smaller. If the sore is very painful or lasts longer than two weeks, it is a good idea to contact your dentist for an exam. Sometimes other conditions can look like a canker sore, and a dental visit is the only way to know for sure.

How to Get Relief From a Canker Sore on the Tongue

While there is no instant cure, there are ways to ease the discomfort. Here are some general tips that may help:

• Avoid spicy, acidic, or rough foods that can irritate the sore
• Rinse your mouth with mild saltwater to soothe the area
• Use a soft-bristled toothbrush to avoid further irritation
• Stay hydrated and try to get enough rest

There are products at most stores designed for mouth sores, such as gels and mouth rinses. If you are wondering how to get rid of canker sore fast or how to get rid of a canker sore in 24 hours, keep in mind that these options may help ease symptoms, but the sore usually needs several days to heal fully.

When Should You See a Dentist?

Most canker sores are harmless and will clear up on their own. However, you should reach out to us at Sullivan Family Dental if:

• The sore is extremely painful or makes it difficult to eat or drink
• The sore lasts longer than two weeks
• You get canker sores frequently
• You have other symptoms, such as fever, swollen glands, or sores spreading outside your mouth

An exam is the best way for your dentist to determine if it is a typical canker sore or another condition. Sometimes, sores that do not heal or keep coming back can be a sign of something more serious.

Tips to Help Prevent Canker Sores

There is no guaranteed way to prevent a canker sore on the tongue, but these habits may lower your chances:

• Practice good oral hygiene with daily brushing and flossing
• Eat a balanced diet with plenty of vitamins and minerals
• Protect your mouth from accidental bites or injuries
• Reduce stress when possible

If you think your canker sores might be triggered by food, try keeping a food diary to help spot patterns.
