Dragon's Teeth may be found in the Badlands on Eastern Kingdoms, within the scar that Deathwing left in his wake. A skill level of 195 in Herbalism is required to gather this herb. It is a grind to harvest, but the rewards are plentiful. Dragon's Teeth may be a lucrative selling item in the Auction House because of its rarity and somewhat painstaking and time consuming collection-effort.
