Wolf teeth are vestigial teeth which sit in from of the first cheek tooth. They do not have any purpose or use in grinding feed. Many horses will have wolf teeth on the upper arcades and infrequently, they can be seen on the lower arcades.
Wolf teeth are usually erupted by six months of age and if present and unerupted at that time, they are termed “blind” wolf teeth. Whether wolf teeth are erupted or unerupted, they can cause significant issues with the bit when the bit pulls soft tissues onto the wolf teeth.
It is recommended that any horse that will have a bit in its mouth should have their wolf teeth extracted. This usually occurs during a colt’s castration or a filly’s first float.
