Dental hand piece come in either without light on the tip of the hand piece, or with light. The type that comes with light is usually powered by the fiber optic source which requires significant investment in the matching dental chair and the related fiber optic system. Now our revolutionary new product TLC E-Generator hand piece brings light to dental offices that have been using hand pieces that do not have the light on the tip.
