(b) an abrasive disposed in a nonfibrous composition or a second fibrous composition that is free of fluoride,
wherein the solid unit dose oral care composition has a dissolution time of about 50 seconds to about 250 seconds.
2 . The unit-dose oral care composition of claim 1 , wherein the fluoride ion source comprises sodium fluoride, sodium monofluorophosphate, amine fluoride, or combinations thereof.
3 . The unit-dose oral care composition of claim 1 , wherein the composition comprises from about 0.01% to about 10%, by weight of the unit-dose oral care composition, of metal selected from tin, zinc and combinations thereof.
4 . A solid unit-dose oral care composition comprising:
(a) a first fibrous composition layer comprising fluoride;
(b) a second fibrous composition layer comprising fluoride, wherein at least one of the first or second fiber compositions comprise a polymer; and
(c) a non-fibrous composition disposed between the first and second fibrous composition layers, wherein the non-fibrous composition comprises a calcium abrasive, and
wherein the first and second fibrous composition layers are bonded together along an edge to encase the non-fibrous composition.
5 . The unit-dose oral care composition of claim 1 , wherein the unit-dose oral care composition has from about 2% to about 10%, by weight of the unit-dose oral care composition, of the fluoride ion source.
6 . The unit-dose oral care composition of claim 1 , wherein the unit-dose oral care composition has at least about a 1500 ppm fluoride uptake.
7 . The unit-dose oral care composition of claim 1 , wherein the unit-dose oral care composition comprises from about 0.01% to about 40%, by weight of the unit-dose oral care composition, of calcium selected from calcium abrasive, calcium salt, and combinations thereof.
8 . The unit-dose oral care composition of claim 7 , wherein the unit-dose oral care composition has at least about a 1000 ppm average fluoride uptake.
9 . The unit-dose oral care composition of claim 7 , wherein the unit-dose oral care composition has at least about a 2000 ppm average fluoride uptake.
