Bytesize Science takes on a common breakfast disturbance — the foul taste of orange juice after you brush your teeth. Toothpaste is loaded with a cornucopia of chemicals that add flavors, body, texture, and most importantly, the ability to clean your teeth. One compound in particular, a detergent known as sodium lauryl sulfate, is responsible for the suds that you produce when brushing. As it turns out, this compound has an interesting effect on your mouth’s taste receptors. Watch the video to find out exactly how SLS alters your sense of taste, and be prepared to amaze your friends at breakfast when you drop chemical facts on why this bitter combo leads to such a puckered up, gross experience.
