Benzocaine is a topical anesthetic that is capable of interfering with the body’s natural impulse of certain nerves that are responsible for conducting electrical signals. Benzocaine purposely interferes with the transmission of the nerve impulses that send pain messages to the brain. Wherever benzocaine is applied, it numbs that area immediately. It is used many times as first aid creams, sunburn healing medication, and also poison ivy treatment. Benzocaine is also used as a method to numb the gums in the mouth during dentist visits.
