Canker sores, also known as aphthous ulcers, are painful, shallow lesions that can develop inside the mouth on the soft tissues, such as the gums, tongue, and inner cheeks. Dermatologists often encounter patients seeking relief from the discomfort caused by these sores, which can interfere with eating, speaking, and overall oral hygiene. Understanding the causes, symptoms, and management of canker sores is crucial for effective care.

The exact cause of canker sores remains unclear, but they are thought to be associated with various factors, including stress, minor injuries to the mouth, certain foods, and even hormonal fluctuations. Unlike cold sores, canker sores are not contagious and are not linked to the herpes virus.

Canker sores typically present as round or oval-shaped ulcers with a white or yellowish center and a red border. Dermatologists can usually diagnose them based on their distinctive appearance, although in some cases, further evaluation may be needed to rule out other oral conditions.

While canker sores often heal on their own within one to two weeks, dermatologists may recommend over-the-counter topical ointments or mouth rinses containing ingredients like benzocaine or hydrogen peroxide to alleviate pain and promote healing. In some cases, prescription-strength topical or oral medications may be necessary for more severe or persistent sores.

Preventive measures for canker sores include maintaining good oral hygiene practices, avoiding foods that may trigger irritation, and managing stress. Dermatologists play a key role in educating patients about these preventive measures and providing guidance on effective treatments, contributing to the overall well-being of individuals dealing with canker sores.

In conclusion, canker sores are common, painful oral lesions with various potential causes. Dermatologists offer valuable insights into their management, providing relief and empowering individuals with the knowledge to prevent and address these bothersome oral ulcers.
