I discovered yesterday that a lot more goes into toothpaste that I originally thought. Limestone, rock salt, silica, saccharin, glycerin , sodium fluoride, chalk, and baking soda could all be scrubbing your teeth. Makes me regret eating a small tube of Crest Kids toothpaste on a dare when I was in middle school. Stupid kids… but I digress.

The roman’s toothpaste included urine, so I guess chalk is better than that. The Chinese were warned in 2007 that antifreeze was being used to produce their toothpaste. Not surprising- the Chinese seem to enjoy poisoning everything.

Mint flavored toothpaste is the most popular, but there are other bizarre flavors like bourbon, pine, apricot, etc.

Source: How it’s Made or similar Discovery Channel or Science Channel type show, some help from wiki and this site was remarkably helpful in my quest to find more details on what toothpaste is made of.
