Why does orange juice taste bad just after cleaning your teeth?

When you brushes your teeth with a toothpaste that contains sodium lauryl sulfate (or SLS), you notice this bitterness effect.





SLS reduces the sweet taste of sucrose (sugar) and at the same time strengthens the bitterness of citric acid (responsible for the sour and bitter taste of orange juice) by about ten times!

Reply:Acid and mint flavour clash; you%26#039;d have the same problem if you had a glass of champagne after cleaning your teeth. It would taste like plonk!


Your taste buds can%26#039;t cope with the two flavours and they conflict.

there is a chemical in toothpaste that numbs ur taste buds for a while, especially the sweet ones, leaving the sour and bitter ones. now orange juice tastes: sweet, sour, AND bitter, so taking away sweet would make it sour and bitter
