Abstract: The present invention includes improvements to a device with bristles that makes it possible to perform oral hygiene tasks to remove quickly impurities in the oral cavity, in particular when the user is travelling and does not carry a toothbrush and, due to time constraints, requires quick and effective cleaning. The cleaning device may also include luffa sponges, water-soluble films, spheres with toothpaste or channels that provide flexibility to a membrane which, when bending, generates a vacuum and is placed on the tongue in order to be used as a toothbrush handle. The device provides a better fitting and handling in the mouth of a user, since it avoids the generation of vacuum when actuated, and also has a membrane surrounded by a cylindrical section that allows its handling since it adapts to the tongue.
