14 . The oral care system of claim 12 wherein the first component is substantially free of chlorite ion or a precursor thereof.
15 . The oral care system of claim 12 wherein the second component is substantially free of copper ion or a precursor thereof.
16 . The oral care system of claim 12 wherein the second component has a molar excess of a chlorite ion or precursor thereof relative to copper ion or precursor thereof.
17 . A method of administering an oral care composition comprising administering a first component comprising a copper ion or a precursor thereof; and administering a second component comprising a chlorite ion or a precursor thereof;
wherein the first and second component combine form a composition in the mouth of a user or combine just prior to administration in the mouth of a user.
18 . The method of claim 17 wherein the first and second components are administered simultaneously.
19 . An oral care method, comprising:
an oral care device comprising:
a first compartment and a first component stored within the first compartment, wherein the first component comprises a stannous salt;
a second compartment and a second component stored within the second compartment, wherein the second component comprises a peroxide source; and dispensing the second component after the first component.
20 . The oral care method of claim 19 , wherein the oral care device further comprises a first outlet in fluid communication with the first compartment and a second outlet in fluid fluid communication with the second outlet.
21 . The oral care method of claim 20 , wherein the oral care device further comprises a first pump associated with the first outlet and a second pump associated with the second outlet, wherein the first pump is used to pump the first component and the second pump is used to pump the second component.
22 . An oral care method comprising:
an oral care device comprising:
a first compartment and a first component stored within the first compartment, wherein the first component comprises a stannous salt;
a second compartment and a second component stored within the second compartment, wherein the second component comprises a chlorite source; and
dispensing the second component after the first component.
23 . An oral care method comprising:
an oral care device comprising:
a first compartment and a first component stored within the first compartment, wherein the first component comprises a stannous salt;
a second compartment and a second component stored within th second compartment, wherein the second component comprises a polyphosphate; and
dispensing the second component after the first component.
24 . An oral care method comprising:
an oral care device comprising:
a first compartment and a first component stored within the first compartment, wherein the first component comprises a stannous salt;
a second compartment and a second component stored within th second compartment, wherein the second component comprises a comprises a peroxide source and a quaternary ammonium compound; and
dispensing the second component after the first component.
25 . An oral care method comprising:
an oral care device comprising:
a first compartment and a first component stored within the first compartment, wherein the first component comprises a metal catalyst;
a second compartment and a second component stored within th second compartment, wherein the second component comprises a comprises a peroxide source; and
dispensing the second component after the first component.
26 . An oral care method comprising:
an oral care device comprising:
a first compartment and a first component stored within the first compartment, wherein the first component comprises a fluoride source and wherein the first component has a pH between about 2 and about 7;
a second compartment and a second component stored within th second compartment, wherein the second component has a pH greater than about 7; and
dispensing the second component after the first component.
