Can hydrogen peroxide be used for oral ulcers?

In general, hydrogen peroxide can be used for oral ulcers, but it should be used with caution.

Hydrogen peroxide has antibacterial and disinfectant properties. For oral ulcers caused by bacterial or viral infections, using hydrogen peroxide can effectively kill these pathogens, help reduce inflammation, and promote healing of the ulcerated area. Due to its strong oxidizing properties, hydrogen peroxide can disrupt the environment in which bacteria thrive, thereby helping to prevent and control infection of the ulcerated area.

However, hydrogen peroxide also has certain irritant properties. For individuals with thin or sensitive oral mucosa, its use may cause mucosal damage and increase pain. Additionally, high-concentration hydrogen peroxide may cause irritating burns to the skin and mucous membranes. It is recommended to dilute hydrogen peroxide to an appropriate concentration before use in order to minimize irritation to the oral mucosa.

It is important to use it in moderation, as excessive use of hydrogen peroxide may worsen mucosal damage. Therefore, it should be used under medical guidance to avoid self-administration without proper evaluation. Hydrogen peroxide can serve as an adjunctive treatment for oral ulcers, but it cannot completely cure them. Thus, while using hydrogen peroxide, other treatment methods should also be employed, such as maintaining good oral hygiene, avoiding irritating foods, and supplementing with vitamins.
