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

Because you haven’t brushed for long enough. You should be brushing for at least 2 minutes or until the taste of the toothpaste changes in your mouth.

When the taste changes, you can stop brushing and food will taste more normal.
