  • Activating brush tip applicators for dental bleaching compositions
    Patent number: 7740479
    Abstract: A brush tipped applicator includes an applicator tip having a body defining an external surface and an internal conduit. The applicator tip body can have a proximal end defining a proximal opening of the internal conduit and a distal end. The proximal end of the applicator tip body can have a first fastener that is configured for being coupled to a fastener (i.e., second fastener) of a member containing the dental bleaching composition such that the internal conduit of the applicator tip body is capable of being fluidly coupled with the dental bleaching composition. Additionally, the brush tip includes at least one filament disposed on the external surface of the applicator tip body. A dental bleach activator disposed within the filament in an amount sufficient for activating the dental bleaching composition for whitening the teeth.
