However, if two or more males are kept together, all of them should have their fighting teeth cut to avoid torn ears, bites on testicles, and other injuries. Fighting teeth will continue to grow, so if they are cut soon after eruption, it is important to check from time to time to see how much they have grown. If they are too long, they should be cut again. Usually this only has to be done twice in a male's life. Fighting teeth can either be removed surgically by a veterinarian, or quickly and easily be sawed off by you or your veterinarian, using obstetrical wire.
Most llamas seem to find the procedure nonpainful and nonthreatening.
Often they are bothered more by having someone's fingers in their mouth than they are by the actual process of tooth-sawing. In order to cut fighting teeth, the animal must be restrained securely to keep his head steady. Putting the llama in the chute and cross-tying the head works well. Two people are needed to saw fighting teeth. Both should wear glasses or some sort of eye protection, since the cut tooth can fly off at a high speed in an unanticipated direction.
