This invention relates to oral care compositions comprising a basic amino acid or salt thereof, a zinc source, and a preservative, as well as to methods of using and of making these compositions. 2. The oral care composition of claim 1 , wherein the basic amino acid is present in an amount corresponding to 1% to 15% wt. of the total composition weight.3. The oral care composition of claim 1 , wherein the basic amino acid is arginine.4. The oral care composition of claim 1 , wherein the arginine is L-arginine.5. The oral care composition of claim 1 , wherein the basic amino acid is arginine bicarbonate.6. The oral care composition of claim 1 , wherein the arginine is present at about 8% wt.7. The oral care composition of claim 1 , wherein the basic amino acid is ionized by neutralization with an acid or a salt of an acid.8. The oral care composition of claim 1 , wherein benzyl alcohol is present at about 0.7% wt.9. The oral care composition of claim 1 , wherein the polyphosphate is tetrasodium pyrophosphate.10. The oral care composition of claim 1 , wherein methylisothiazolinone is present in from 0.01%-0.05% wt.11. The oral care composition of claim 10 , wherein methylisothiazolinone is present at about 0.01% claim 10 , 0.03% claim 10 , or 0.05% wt.12. The oral care composition of claim 1 , wherein sodium bicarbonate is present from 0.5%-2.0% wt.13. The oral care composition of claim 12 , wherein sodium bicarbonate is present at about 1.0% wt.14. The oral care composition of claim 1 , wherein sodium methyl cocoyl taurate (tauranol) is present from 1.0%-2.0% wt.15. The oral care composition of claim 1 , wherein the ratio of the amount of zinc oxide to zinc citrate is from 1.5:1 to 4.5:1.16. The oral care composition of claim 1 , wherein the ratio zinc oxide to zinc citrate is about 1.5:1 claim 1 , 2:1 claim 1 , 2.5:1 claim 1 , 3:1 claim 1 , 3.5:1 claim 1 , or 4:1.17. The oral care composition of claim 16 , wherein the ratio of zinc oxide to zinc citrate is 2:1.18. ...
