If you want to use one, go ahead. I personally see no point to it, unless of course the individual ball python is really fiesty. But then again, I have a really fiesty ball python that bites the crap out of me, and it doesn't hurt. The teeth are barely big enough to leave a mark, though they still do. I'm sure the breeder would have let you know if the baby you are buying is more on the "nippy" side, as they are rather rare IMO. But if it makes you more comfortable, then go right ahead.
