Claim:
A brush tip for applying a dental bleaching composition to teeth, the brush tip comprising: an applicator tip having a body defining an external surface and an internal conduit fluidly coupled to a conduit opening, said body having a proximal end defining a proximal opening of the internal conduit, said proximal end having a first fastener for being coupled to a second fastener of a member containing a dental bleaching composition, said body having a distal end defining a distal opening of the internal conduit through which a dental bleaching composition exits during use of the brush tip; at least one filament disposed on the external surface and at the distal end of the body and forming a contact area when in contact with a tooth that is less than a surface area of the tooth; and a dental bleach activator disposed on or within the filament in an amount sufficient for activating a dental bleaching composition for whitening teeth, the brush tip providing that the dental bleach activator does not contact a dental bleaching composition before exiting the distal opening of the internal conduit.
