Others can chime in any time, but my experience with the bear skull I did was all the teeth want to come out. Really nasty. I lost the small ones and it was my bear so no big concern. Working on my son's lion skull right now and all teeth are loose and come out easily when pulled or the rotten water is poured out. So I took a window screen from Home Depot, blue gloves and poured the bucket out on the screen. Then forced the rotten sludge through the screen until I found every tiny tooth. Not fun, but there are worse things. So here is how the lower jaw sits right now. Rest of skull still degreasing. I am deciding if lower jaw is done or not.

So long story short. If you are doing predators, be prepared to sludge dive and degrease a long time.

Oh and due to teeth coming out, I'd only do one bear skull per 5 gallon home depot bucket. Don't want teeth mixed up.
