Abstract

This disclosure relates to oral care appliances and methods of forming oral care appliances. A disclosed oral care mouthpiece includes a flexible membrane and a set of oral care elements attached to the flexible membrane. The set of oral care elements have a composition with a hardness of at least 50 Shore Type A (shA). Each oral care elements in the set of oral care elements has a minimum stiffness value higher than 4×10newton meters and lower than 6×10newton meters. The stiffness value and hardness of the oral care elements are both critical values for the disclosed appliances and methods. The stiffness value can be expressed as the product of the Young modulus of the oral care element and the moment of inertia of the oral care element divided by the length of the oral care element.
