1. A dental varnish comprising a rosin, resin, a fluoridizing agent, a solvent, an optional remineralization agent, an optional flavor additive, an optional sweetener and optionally an oxide, wherein the dental varnish is transparent, exhibiting a transmittance of at least 50%, wherein the rosin is present in the dental varnish from about 18 to about 60 percent by weight and wherein the resin is a reaction product of 2,2′ bis[p-(2′-hydroxy-3′ methacryloxypropoxy)phenyl]propane (BisGMA) and hexamethylene diisocyanate (HMDI) and is present in the dental varnish from about 25 to about 60 percent by weight.

3. The dental varnish according to claim 2 , wherein the rosin is at least a partially hydrogenated rosin.
4. The dental varnish according to claim 1 , wherein the dental varnish exhibits a fluoride release over a two hour time period of from 14000 μg/g to 17000 μg/g.
5. The dental varnish according to claim 1 , wherein the dental varnish exhibits a ΔE of less than 1.
6. The dental varnish according to claim 5 , wherein the ΔE is from 0.05 to 0.98.
7. The dental varnish according to claim 1 , wherein the transmittance is from 55% to 95%.
