Those sound like canines, not wolf teeth. Wolf teeth are on the bottom. My mare is 20 and still has one, it doesn't cause her any issues. I did have my gelding's removed though, to prevent any problems. Posted via Mobile Device
IIRC, it's much easier to take them out when they're small and not firmly rooted yet. So a lot of people will have them taken out as soon as they can to avoid a more expensive/complicated extraction if/when they interfere with the bit in the future.
Oh and another thing, the wolf/canine(i'm confused) teeth are about 1/2 to 1 cm apart from the molar. Would that cause a problem? He has no wolf teeth on the bottom jaw. Is it possible for them to erupt yet?
