Canker sores are small, painful ulcers that develop inside the mouth, often on the tongue, cheeks, or gums. They are distinct from cold sores, which are caused by a virus and typically appear outside the mouth around the lips. Canker sores, also known as aphthous ulcers, are a common source of discomfort, leading many to seek quick relief due to the pain they cause during eating and talking.
The Question of Popping
While the discomfort of a canker sore might make you want to “pop” it like a pimple, this is strongly discouraged. Canker sores are open wounds or ulcers within the mouth’s lining, not fluid-filled pustules like pimples, so there is no pus or fluid to release. Attempting to pop a canker sore only further damages the delicate tissue, potentially worsening the pain and delaying the natural healing process.
Why Popping is Harmful
It significantly increases pain and can prolong the healing time, as the natural repair mechanisms of the body are disrupted. An open wound in the mouth is highly susceptible to secondary bacterial infections from the oral environment, which can introduce new complications and further delay recovery. Popping can also result in a larger, more irritated sore, and in some cases, may even lead to scarring.
Effective Relief and Healing
Instead of attempting to pop a canker sore, several safe and effective methods can provide relief and promote healing. Rinsing the mouth with a saltwater solution (1 teaspoon of salt in 1/2 cup warm water) or a baking soda rinse can help cleanse the area and reduce irritation. Over-the-counter options include oral numbing gels containing ingredients like benzocaine or lidocaine, which offer temporary pain relief when applied directly to the sore. Canker sore patches can also be applied to cover the sore, providing a protective barrier and aiding healing. Avoiding irritating foods such as acidic, spicy, or abrasive items can also help prevent further discomfort and allow the sore to heal.
Most canker sores resolve on their own within one to two weeks. However, if a canker sore is unusually large, frequently recurs, causes extreme difficulty eating or drinking, or lasts longer than two weeks, it is advisable to consult a healthcare provider. These instances might indicate an underlying issue that requires professional assessment.
