Abstract
A device for delivering medicaments to oral structures contains a flexible backing having a plurality of microstructures protruding from one surface of the backing, and a binder layer containing medicaments disposed on the backing and/or microstructures. Because the device contains microstructures that form obstacles or barrier that minimize the flow of medicaments away from the target oral structure, the medicaments stay at the desired longer thereby being more effective at treating the oral structure. One particularly useful application of the inventive device is for whitening teeth.
