The invention relates to a mouthpiece for performing a treatment of teeth such as teeth whitening. Accordingly, the mouthpiece may be arranged for cosmetic treatment. The treatment is based on illumination of the teeth of light with a suitable wavelength. The mouthpiece is designed so that light from light sources, e.g. LED's, is sufficiently homogenized so that the light irradiance at the teeth is sufficiently uniform to achieve good treatment results. Furthermore, the mouthpiece is designed so that the irradiance at the teeth is sufficiently high to achieve efficient treatment and so that heating of the teeth is minimized to an acceptable heating.

Mouthpiece for dental treatment

A system for providing an oral care agent includes a first layer containing the oral care agent and a second layer. The first layer can be applied directly to teeth. The second layer can subsequently be applied onto the first layer to inhibit leakage of the oral care agent outwards into the mouth.

System and method for applying oral care agents

A varnish composition is provided comprising a hydrophilic oral care agent, such as a peroxide material, dispersed in a solution of a film-forming hydrophobic polymer in a non-polar solvent. The solvent is selected so as to be a good solvent for the polymer and to be susceptible to evaporation. The composition can be applied as a single layer varnish, preferably a whitening varnish. E.g., the dispersed hydrophilic peroxide material is an aqueous peroxide solution, such as a hydrogen peroxide solution, whereby the dispersion is an emulsion.
