You get to level your dragons of a given element past level 10 once you A) buy the appropriate element shrine, and B) level 50 dragons of that element up to level 10. You don't have to have them in your park all at once, meaning any dragons that were level 10 that you sell will count. The resulting orb above dragons' heads is just a visual cue that you have been a dragon breeding and leveling fiend! Think of them like little badges of honor.
