Why does toothpaste make whatever you eat after brushing taste bad?

Question

What’s the property of toothpaste that makes some foods (orange juice is the classic example, I guess) taste SO bad if you eat right after brushing?

Answer 1

My understanding is that toothpaste dulls your receptors that taste sweetness. So when you drink orange juice, you’re tasting all the sour without the sweetness to balance it out and it tastes terrible.
