What Are Canker Sores

Canker sores, also known as aphthous ulcers, are open sores that typically appear inside the lips, cheeks, or on the floor of the mouth. Canker sores are not contagious and usually resolve within two to three weeks without scarring. Although the exact cause of canker sores is unknown, they may be triggered by certain foods, allergies, stress, or physical injury, such as dental work or biting the inside of the cheek.

Symptoms

Canker sores can range in size from pinpoint to a little bigger than a quarter in diameter. Usually there is only one canker sore at a time, but sometimes there will be several together in a cluster. The sores are round with a white or yellow center and a red border. They may cause a burning or tingling sensation prior to appearing, and can cause pain and discomfort while eating, drinking, or talking.

Treatment

Canker sores usually disappear on their own within two to three weeks. Applying a topical treatment or pain reliever, such as milk of magnesia, may help reduce discomfort. There are also over-the-counter medications and creams that can help alleviate pain and speed healing. If the sores are recurring or do not seem to be going away, it is recommended to see a doctor or dentist.

Warm salt water rinses may also help relief discomfort, but it is important to be careful not to scrub the area too aggressively, as this could exacerbate the pain and delay healing. Certain foods and toothpastes may also aggravate the area, so identifying and avoiding triggers is important.

Conclusion

Canker sores are a common and usually harmless condition that usually resolves within two to three weeks. While the exact cause of canker sores is unknown, they may be triggered by certain food allergies, stress, or physical trauma. Over-the-counter medications and creams may help reduce pain and speed up healing, but it is important to see a doctor or dentist if the sores are recurring or do not seem to be going away. Warm salt water rinses are also helpful in reliefing discomfort, and it is important to identify and avoid foods and toothpastes that may worsen the sores.
