Canker sores, also known as aphthous ulcers, are painful sores that develop inside the mouth. They can make eating, drinking, and speaking uncomfortable. Fortunately, there are several over-the-counter (OTC) treatments available that can help reduce pain and promote healing.

Common OTC Treatments for Canker Sores

Many products are designed to provide relief from the pain and discomfort of canker sores. These treatments typically focus on numbing the area, protecting the sore, or speeding up healing.

Topical Gels and Ointments

Topical medications are applied directly to the sore. They often contain numbing agents like benzocaine or lidocaine, which temporarily relieve pain. Examples include products like Orajel and Anbesol. Applying these gels at the first sign of a sore can help reduce discomfort.

Protective Pastes and Films

These products form a protective barrier over the sore, shielding it from irritation caused by food and drinks. They often contain ingredients like carboxymethylcellulose or benzalkonium chloride. Examples include Canker Cover and Peroxyl.

Rinses and Mouthwashes

Antiseptic mouthwashes can help reduce bacterial growth and promote healing. Look for products containing hydrogen peroxide or chlorhexidine. These are especially useful if you have multiple sores or if the sore persists for more than a week.

Additional Tips for Managing Canker Sores

Besides OTC treatments, consider these tips to help manage canker sores:

  • Avoid spicy, acidic, or rough-textured foods that can irritate the sore.
  • Maintain good oral hygiene to prevent infection.
  • Use a soft-bristled toothbrush to avoid irritating the sore.
  • Apply ice or a cold compress to reduce swelling and pain.
  • Stay hydrated and avoid irritating beverages like citrus juices.

If a canker sore lasts longer than two weeks, or if pain becomes severe, consult a healthcare professional for further evaluation and treatment options.
