Canker sores, medically known as aphthous ulcers, are small, painful lesions that develop inside the mouth, typically on soft tissues like the tongue, cheeks, lips, or at the base of the gums. These shallow ulcers are often round or oval with a white or yellowish center and a red border, causing discomfort that can make eating and talking challenging. Although common, especially among adolescents and young adults, they are not contagious. The pain they cause often leads to a desire to “fix” or “remove” these sores.
Why Popping a Canker Sore is Not Recommended
Popping or disrupting a canker sore is discouraged due to negative consequences. When a canker sore is popped, it can cause increased pain and discomfort because the delicate tissue within the mouth is further damaged. This action also opens the wound, creating an entry point for bacteria from hands or the mouth, which elevates the risk of infection.
Manipulating the sore can significantly delay its natural healing process. Canker sores are ulcers, not fluid-filled blisters or pimples, meaning there is nothing to drain. The body’s natural healing mechanism involves closing the sore and regenerating healthy tissue, a process disrupted by any interference. Popping a canker sore can also lead to the formation of scar tissue, potentially leaving lasting marks inside the mouth. There is no benefit to popping a canker sore; it does not accelerate healing and often worsens pain and the overall condition.
Effective Management and Relief
Managing canker sores effectively focuses on promoting natural healing and reducing discomfort. Rinsing with warm salt water (one teaspoon salt in half a cup water, swish 30 seconds) or a baking soda solution (one teaspoon baking soda in half a cup water, swish 15-30 seconds) can alleviate pain and reduce inflammation. Repeat every few hours as needed.
Over-the-counter topical gels or patches can also provide relief. Products containing benzocaine or hydrogen peroxide can numb the affected area and help cleanse the sore. Avoiding acidic, spicy, or abrasive foods is beneficial, as these can irritate the sore and intensify pain. Maintaining good oral hygiene through gentle brushing and flossing helps keep the mouth clean and supports the healing process. If canker sores are unusually large, extremely painful, persist for longer than two weeks, recur frequently, or are accompanied by a fever, seeking medical attention from a doctor or dentist is advisable.
