Abstract
A dental brush with enhanced bristles has a body including a grip and a head. Attached to the head are at least some bristles made from a shape memory alloy with a composition that allows for superelastic attributes at the operational temperature ranges of the dental brush. These superelastic attributes allow metal bristles to be used and provide the dental brush with increased operational life. Other attributes of the shape memory alloy bristles include a hydrophobic nature that discourages growth of bacterial colonies on and near the dental bristles. The shape memory alloy dental bristles are individually supported allowing greater variety. in positioning the bristles on the dental brush head. The height, thickness, and shape of the shape memory alloy bristles can also be tailored to increase effectiveness of the dental brush. Further aspects of the shape memory alloy dental bristles include coatings on the bristles to modify color, lubricity, surface hardness, and abrasivity.
