1. A glass composition comprising 20-50% by weight CaO, at least 20% and less than 50% by weight P2O5, less than 3% by weight Al2O3, less than 10% by weight Li2O, Na2O, and K2O combined, and 0-60% by weight of SrO, MgO, BaO, ZnO, or combinations thereof. 2. The glass composition of claim 1, wherein the glass composition is amorphous. 3. The glass composition of claim 1, wherein the glass composition is at least partially crystalline. 4. The glass composition of claim 1, wherein the glass composition is in a finely divided form of particles, fibers, or platelets. 5. The glass composition of claim 4, wherein the particles, fibers, or platelets are surface-treated. 6. The glass composition of claim 5, wherein the surface treatment comprises a silane. 7. The glass composition of claim 1, further comprising fluoride, wherein the amount of fluoride is less than 25% by weight of the glass composition. 8. The glass composition of claim 1, further comprising B2O3, wherein the amount of B2O3 is less than 30% by weight of the glass composition. 9. The glass composition of claim 1, further comprising SiO2, wherein the amount of SiO2 is less than 20% by weight of the glass composition. 10. The glass composition of claim 9, wherein the amount of SiO2 is less than 1% by weight of the glass composition. 11. The glass composition of claim 1, further comprising a rare earth oxide, wherein the rare earth oxide is up to 40% by weight of the glass composition. 12. The glass composition of claim 1, further comprising ZrO2, wherein the amount of ZrO2 is less than 15% by weight of the glass composition. 13. A dental composition comprising the glass composition of claim 1. 14. The dental composition of claim 13, wherein the dental composition comprises at least 30% by weight of the glass. 15. The dental composition of claim 13, further comprising a hardenable resin. 16. The dental composition of claim 13, further comprising a polymeric film former. 17. The dental composition of claim 13, further comprising a calcium source. 18. A method of treating a tooth structure comprising contacting the tooth structure with a dental composition according to claim 13. 19. A method of preparing a dental article comprising hardening a dental composition according to claim 15 to fabricate a dental article selected from the group consisting of crowns, fillings, mill blanks, orthodontic devices, and prostheses.
