A teeth whitening system comprises a dissolvable matrix that supports a whitening material. The combination of dissolvable matrix and whitening material is attached to one or more teeth so that the whitening material is exposed to the one or more teeth over time as the dissolvable matrix slowly dissolves. In some examples, the combination is applied to a tooth with the whitening material adjacent to the tooth. In some examples, the whitening material is contained within one or more vesicles, pockets, or reservoirs within the dissolvable matrix and is placed in contact with the teeth by crushing or adhering the dissolvable matrix to the teeth. In still other examples, the whitening material is mixed with the dissolvable matrix. In some examples, the whitener is composed of precursor materials that are separated until usage, for example by distributing the different precursors in separate vesicles until pressed against one or more teeth for usage. Teeth whitening units can be any suitable size and shape for application to one or more teeth, for example by pressing or crushing the unit against a tooth.
