Hog skull

You can boil for a short time with baking soda in the water also. The baking soda cuts down on the boiling time tremendously. Don't boil to long or the skull sutures will get loose. The teeth loosen up and can be pulled and reinserted. Then put hair bleach on like a paste. Wrap with plastic for 24 hours then wash the bleach off. Glue the teeth back in and glue any of the skull sutures that come loose. The whole process can be done in 1-1/2 days.
You can also "cheat" and leave more of the tooth out of the socket to make the mount look better.
