An oral care implement has a head portion with tooth cleaning elements on one surface thereof and a reservoir containing at least one active agent. A capillary channel extends through at least a portion of the oral care implement to deliver active agent(s) to one or more outlets. In one aspect, a vibration-producing device is provided to vibrate at least a portion of the implement to enhance the function of tooth cleaning elements and the delivery of the active agent through capillary action. A variety of active agents can be administered for therapeutic, hygienic, and/or other benefits, such as fresh breath, tooth whitening, or producing sensations of heat, cool, or tingling.

The toothbrush of claim 3, wherein the active agent is selected from the group consisting of (i) an antibacterial agent selected from the group consisting of chlorhexidine, cetyl pyridininum chloride, triclosan, and zinc salts; (ii) an oxidizing or whitening agent selected from the group consisting of hydrogen peroxide, urea peroxide, sodium percarbonate. and PVP-H2O2; (iii) a gum health active selected from the group consisting of bachalin, polyphenols, triclosan, ethyl pyruvate, and guanidinoethyl disulfide; (iv) a nutritional ingredient selected from the group consisting of vitamins, minerals, amino acids, vitamin E. and folic acid; (v) a tartar control or anti-stain agent selected from the group consisting of phosphate salts, poinylphosphonic acid, and PVM/MA copolymer; (vi) a flavor or flavor ingredient selected from the group consisting of menthol, carvone, anethole, aldehydes, esters, alcohols, and oils of spearmint, peppermint, wintergreen, sassafras, dove, sage, eucalyptus, marjoram, cinnamon, lemon, lime, grapefruit, or orange; (vii) an occluding agent selected from the group consisting of bioactive glass and arginine salts; and combinations thereof. 5. The toothbrush of claim 1, wherein the reservoir is a replaceable cartridge. 6. The toothbrush of claim 1, which comprises a first section containing the handle, head, and channel, and a second section containing the reservoir, wherein the second section is releasably attached to the first section. 7. The toothbrush of claim 1 further comprising an outlet located on the first surface of the head, the capillary channel delivering the active agent from the reservoir to both the porous outlet on the second surface of the head by capillary action and to the outlet on the first surface of the head by capillary action. 8. The toothbrush of claim 1 wherein the capillary channel is a single tube of porous material. 9. The toothbrush of claim 1 wherein the reservoir includes a reticulated foam. 10. The toothbrush of claim 9 wherein the reticulated foam is an open cell polyurethane foam based on polyester. 11. The toothbrush of claim 9 wherein the reticulated foam averages 90 pores per inch. 12. The toothbrush of claim 1 further comprising: an outlet located on the first surface of the of the head, the capillary channel delivering the active agent from the reservoir to both the porous outlet on the second surface of the head by capillary action and the outlet on the first surface of the head by capillary action;wherein the reservoir includes a reticulated foam; andwherein the reticulated foam is an open cell polyurethane foam based on polyester averaging 90 pores per inch. 13. A toothbrush comprising: a handle;a head having a first surface containing at least one tooth cleaning element comprising bristles;a reservoir for storing an active agent;a porous outlet located on a second surface of the head opposite the first surface;a capillary channel that continuously delivers the active agent from the reservoir to the porous outlet by capillary action, wherein the capillary channel is made of a porous material;a soft tissue cleanser constructed of an elastomeric material positioned on the second suface of the head, the porous outlet incorporated into the soft tissue cleanser; andwherein the porous outlet comprises a non-woven pad or membrane through which the active agent can flow for application to an oral surface of a user. 14. A toothbrush comprising: a handle;a head having a first surface containing at least one tooth cleaning element comprising bristles;a reservoir for storing an oral care material;a porous outlet located on a second surface of the head opposite the first surface;a capillary channel that delivers the oral care material from the reservoir to the porous outlet by capillary action, wherein the capillary channel is made of a capillary material and is in continuous fluid communication with the porous outlet; anda soft tissue cleanser constructed of an elastomeric material positioned on the second surface of the head, the porous outlet incorporated into the soft tissue cleanser. 15. The toothbrush of claim 14 wherein the oral care material is an active agent. 16. The toothbrush of claim 14 wherein the capillary material is selected from a group consisting of a fibrous material, a ceramic, a porous material, or combinations thereof. 17. A toothbrush comprising: a handle;a head having a first surface containing at least one tooth cleaning element comprising bristles;a reservoir for storing an active agent;an outlet located on a second surface of the head opposite the first surface;a capillary channel that delivers the active agent from the reservoir to the outlet by capillary action, wherein the capillary channel is made of a capillary material and is in continuous fluid communication with the outlet; anda soft tissue cleanser constructed of an elastomeric material positioned on the second surface of the head, the outlet incorporated into the soft tissue cleanser.
