Anbesol is an over-the-counter topical medication used to relieve pain from minor mouth and gum irritations, such as canker sores, toothaches, and sore gums. It contains active ingredients like benzocaine, which is a local anesthetic that numbs the affected area, providing temporary relief from discomfort. Anbesol is available in various forms, including gels, liquids, and ointments, making it easy to apply directly to the painful area. It is important to follow the instructions on the packaging and consult a healthcare professional if symptoms persist or worsen.
