The principal object of this invention is a device to both hold and sanitize toothbrushes when not in use. Keeping toothbrushes both disinfected and pliable will help to preserve oral hygiene and avoid disease. When the device is opened, sanitizer liquid will gravity feed from a container into a connected bath that contains the toothbrush. Because the container is sealed, a vacuum will form, arresting sanitizer flow and resulting in automatic adjustment of the sanitizer level in the bath. Over time the immersed toothbrush will be treated due to contact with the sanitizer. When the device is closed, sanitizer cannot flow out of the container, which allows the device to be easily moved and cleaned. Any number of such devices can be neatly arranged in order to present and sanitize many toothbrushes. The devices will be low cost, potentially disposable, and function without the need for manual refilling or electricity.
