7. 0. For a normal visit to the dentist without insurance for cleaning purposes it may cost your around $125 which is not very expensive, and the cost of the root canal and crown may be around $1000 or $1100. if you can afford then its not much expensive. . . . . . . . . . . .
Rhonin appears in the Wrath of the Lich King expansion as the leader of the Kirin Tor. He is located in the rebuilt and relocated city of Dalaran in Northrend, with Vereesa Windrunner, Archmage Modera, and Archmage Aethas Sunreaver at his side.
Assuming you aren't a mage and can't teleport yourself: The fastest way to Dalaran is to teleport yourself with one of the sixteen rings of the Kirin Tor. If you played during Wrath, you might still have one laying around in Void Storage. If not, well, they start at 6800 gold (at Exalted with the Kirin Tor).
