Abstract

L'invention concerne un système et un procédé de blanchissement des dents activé par la lumière, comprenant un appareil lumineux ayant un élément lumineux pour projeter de la lumière vers les dents d'un utilisateur et un dispositif de retenue de lèvre, qui peut être une crête de retenue. Ledit dispositif de retenue de lèvre conjointement avec les lèvres de l'utilisateur positionne l'élément lumineux de manière à diriger la lumière vers les dents de l'utilisateur. Le système et le procédé peuvent comprendre un applicateur, par exemple un écarteur dentaire, une bande ou une ruban dentaire, ou une brosse, pour appliquer une composition de blanchissement des dents activée par la lumière sur au moins une partie d'une des dents de l'utilisateur. L'applicateur peut inclure des zones de retenue de composition pour retenir la composition et distribuer la composition sur les dents de l'utilisateur lorsqu'il est positionné des dents de l'utilisateur.
