Summary
Wolf teeth are the small, first premolar teeth. Not all horses have wolf teeth. Wolf teeth typically erupt and are at full size in the first year of life.
Some believe that the presence of wolf teeth interferes with the bit. My opinion is that it depends on the circumstance and the particular character of individual wolf teeth. I see no reason to remove wolf teeth strictly for health reasons. It is only a consideration for horses that will carry a bit in their mouths.
Removal is a simple and routine procedure with few complications. The gum is elevated away from the tooth with a sharp curved scoop-like instrument. The tooth is then scooped out of the socket. The teeth may break off below the gumline or come out complete, including their curved root. It is considered acceptable if the teeth are broken off below the gumline because they usually don't erupt any further. But there should not be any tooth protruding above the gumline.
For convenience, I remove them routinely during routine castrations while a horse is sedated.
The horse is sedated using drugs that provide some pain relief. Local anesthesia is preferred by some vets but is usually not used. I do not use it.
YOUR VET'S ROLE
Your vet should explain to you potential benefits of this procedure versus cost. The procedure is usually quick, with little drama. There is usually mild to moderate resistance to the procedure. Unhandled or poorly handled horses may resist.
The procedure should take at most 2-5 minutes per tooth, unless there are complicating factors. There should be a small amount of blood in the mouth and on the vet's hands after the procedure. The sockets are small and are left open. They usually become packed with feed, but healing takes place rapidly anyway.
YOUR ROLE
While some vets recommend that caretakers flush the sockets after removal, I do not think it is necessary. I usually prescribe follow up care for horses after wolf tooth extraction only when lower wolf teeth have been removed. In this case, I may recommend that caretakers flush the lower sockets once daily with weak salt water.
The mouth heals very rapidly and well. In most cases, horses act as though nothing happened. That said, keep an eye on your horse to be sure they continue to eat well and act normal after the procedure.
I usually recommend that no bit be place in the horse's mouth for a minimum of 3-5 days after the procedure.
