The present invention relates to a unique solution for relieving repetitive stress to dental professionals during the course of a day and is directed to sets of identical instruments, having handles made with varying diameters for grasping, designed to be used interchangeably throughout the day, thus cutting down on the repetitive grasping action through the change of grasp. Therefore, even if a dental professional uses the same type of instrument throughout the day, the hands, wrists and elbows can experience varying rather than repetitive action because the positioning of the hands, wrists and elbows are interchanging throughout the day. The dental instrument may also be ergonomically designed. Additionally, the instrument may also have a vibratory module. Further, a rotator may also be implemented.

A cleaning and whitening system for teeth having an electromagnetic radiation emitting toothbrush and a dentifrice with a photosensitive agent is disclosed. The toothbrush has a cleaning surface, such as bristles. The toothbrush is also adapted to direct electromagnetic radiation toward the cleaning surface. The electromagnetic radiation may be monochromatic or polychromatic. Further, the electromagnetic radiation may be substantially free of ultraviolet radiation.

The dentifrice transmits the electromagnetic radiation through a varying thickness disposed over a target surface during use of the system. As a result, a significant portion of the photosensitive agent reacts, resulting in whitening stains, removing and / or disclosing undesired substances, and / or foaming. The dentifrice may be clear and may have clear abrasive particles. A method for tuning the cleaning and whitening system for teeth includes formulating the dentifrice with photosensitive agents that react to a range of electromagnetic radiation and providing a toothbrush that emits that electromagnetic radiation range. Another method of tuning the cleaning and whitening system includes designing a toothbrush that emits a range of electromagnetic radiation and formulating a dentifrice with photosensitive agents that react to the electromagnetic radiation range.
