On occasion, you will begin to see a bulge on the lower jaw of an alpaca. Usually it starts the size of a marble and can grow from there. These are dangerous because tooth abscesses can infect the tooth, weaken the bone and potentially break the jaw.
Use a wet warm/hot clean rag to hold over the abscess area. Do this until it softens up. Begin moving and breaking the abscess.
When you do you will get a lot of white goo coming out.. This is white blood cells and are there to attack the infection.
