Why does toothpaste change the taste of orange juice?

Easy experiment: Drink orange juice. Brush your teeth. Drink orange juice again. What just happened?

From The American Chemical Society, here’s a Reactions explanation for why most toothpastes change the taste of orange juice. The video includes an intro on the five basic tastes that we’re able to detect: sweetness, sourness, saltiness, bitterness, and umami — a Japanese word that we’ve borrowed to describe a “pleasant savory taste” or “a pleasant, brothy or meaty flavor” — and the ingredients of toothpaste.
