Local anesthetic

A local anesthetic is a medication used to numb a specific area of the body, preventing pain during procedures like dental work, skin tests, or minor surgeries. It works by blocking nerve signals that transmit pain messages to the brain, allowing the area to become temporarily insensitive. Local anesthetics are applied directly to the skin or injected near nerves, providing targeted relief without affecting consciousness or overall body sensation. They are safe when used as directed and are essential for pain management during various medical procedures.
