Why does orange juice taste bad after brushing your teeth?
TLDR Brushing your teeth before drinking orange juice can make it taste bad due to a chemical reaction between the toothpaste's surfactant, sodium lauryl sulfate, and the flavors in the orange juice. This reaction decreases sweetness and increases bitterness, resulting in an unpleasant taste that can take up to an hour to subside.
