Disease description:

My child hasn’t been brushing teeth for a long time. I’ve also noticed this behavior in other children, and oral ulcers have appeared. Is there a relationship between oral ulcers and poor toothbrushing habits?

That’s possible. Infrequent toothbrushing allows oral bacteria to proliferate, potentially causing this condition—and poor oral hygiene may also contribute to other diseases. Therefore, it’s essential to develop good hygiene habits, including brushing your teeth each morning and before bed each night. Oral ulcers may also present with localized symptoms such as swelling, pain, and a sensation of “internal heat” (a traditional Chinese medicine concept often associated with inflammation or infection). Treatment may include oral medications, as prescribed by a physician. In daily life, maintain consistent toothbrushing—both morning and night—to cultivate sound oral hygiene practices and ensure optimal oral health.
