1. An oral care composition comprising fused silica having a particle size wherein D90 is less than about 50 microns, and one or more actives. 2. The composition of claim 1 where the active is selected from the group consisting of antibacterial agents, antiplaque agents, anti-inflammatory agents, anticalculus agents, nutrients, antioxidants, analgesic agents, anesthetic agents, H-1 and H-2 antagonistis, antiviral actives, enzymes, anticaries agents, anticalculus agents, antisensitivity agents, antierosion agents, antimalodor agents, antistain agents, and combinations thereof. 3. The composition of claim 1 wherein the active is an antibacterial agent and selected from the group consisting of cationic antibacterials, metal salts, essential oils, basic amino acids or salts, triclosan, galenical extracts, and combinations thereof. 4. The composition of claim 2 wherein the antibacterial active is a cationic antibacterial agent selected from the group consisting of chlorhexidine, cetylpyridinium chloride, bisiguanides, benzylkonium chloride, benzethonium chloride, and combinations thereof. 5. The composition of claim 1 wherein the active is selected from the group consisting of stannous salts, zinc salts, copper salts, strontium salts, aluminum salts, magnesium salts, copolymers of carboxylated polymers, and combinations thereof. 6. The composition of claim 1 wherein the active is an essential oil. 7. The composition of claim 6 comprising two essential oils wherein the first essential oil is selected from the group consisting of acyclic or non-ring structures and a second essential oil is selected from ring-containing structures. 8. The composition of claim 1 further comprising a chelant. 9. The composition of claim 8 wherein the chelant an alkyl phosphate. 10. The composition of claim 8 wherein the chelant is selected from the group consisting of polyphosphates, polycarboxylates, polypeptides, polyphosphonates, polysaccharides, co-polymers of methyl vinyl ether and maleic anhydride, phytic acid or salts, and combinations thereof. 11. The composition of claim 1 wherein the active is a zinc salt. 12. The composition of claim 11 wherein the zinc salt has a stability of greater than about 85% after two weeks of storage at 25° C. 13. The composition of claim 10 wherein the zinc salt has a stability of greater than about 85% before use. 14. An oral care composition comprising fused silica having a particle size wherein D90 is less than about 50 microns, a cationic antibacterial agent, and a surfactant system. 15. The composition according to claim 14 wherein the surfactant system comprises surfactants selected from the group consisting of non-ionic surfactants, cationic surfactants, betaine surfactants, amphoteric sufactants, and combinations thereof. 16. The composition of claim 1 wherein at least 25% of the fused silica particles are spherical. 17. The composition of claim 1 wherein at least 25% of the fused silica particles are spherical.
