Various dental devices are available for cleaning the mouth, gums and teeth. However, these dental devices may also cause abrasions to the mouth and/or gums. Dental devices may comprise a reservoir for storing a liquid and for application of the liquid to the mouth, teeth and/or gums. The liquid may be an antibacterial liquid, such as a hydrogen peroxide solution, a salt solution or a teeth whitening solution or gel, for example. An antibacterial liquid may be applied to prevent infection of the abrasions. The reservoir may be in a hollow handle of the dental device, such that the liquid may be easily pumped or moved from the reservoir to an outlet at the functional end that may cause the abrasions.
