摘要：
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.
