Anbesol Liquid is a topical anesthetic that provides temporary relief from the pain and discomfort associated with minor mouth sores, such as canker sores, cold sores, and irritated gums. It contains benzocaine, a numbing agent that works by desensitizing the affected area. Anbesol Liquid is suitable for adults and children over the age of two, but it is important to consult with a healthcare professional before use, especially if you have any underlying medical conditions or are pregnant or breastfeeding.
