SOLID TEETH BLEACHING DEVICE

摘要

A teeth bleaching device (100) for bleaching teeth is described being a dry teeth bleaching device, prior to use. The teeth bleaching device (100) comprises a fibrous, non-hydratable polymer structure (110) and a hydratable solid teeth bleaching agent (120) embedded in the fibrous structure prior to use. Upon use, the solid teeth bleaching agent (120) is dissolved by uptake of moisture or saliva in the fibrous structure (110) and released to the teeth. By selecting a predetermined porosity, density and/or fibre diameter, optionally a predetermined dissolving rate and/or release rate of the teeth bleaching agent may be obtained.
