Here’s Why OJ Tastes So Bad Right After You Brush Your Teeth
Have you ever brushed your teeth, then immediately had orange juice, and it’s the worst taste in the world? Here’s the science behind why it happens . . .
There’s an ingredient that creates suds in toothpaste called sodium lauryl sulfate . . . or SLS for short. It’s also in other stuff, like soap and shaving cream.
And one of the side effects when it hits your tongue is it temporarily kills your ability to detect sweet things.
It turns out orange juice is pretty bitter if you remove all the sugar. And since the SLS prevents you from TASTING that sugar, you just taste more of the bitter stuff.
On top of that, SLS also interferes with certain compounds that normally reduce bitterness. So you end up with even more bitter . . . no sweetness to mask it . . . and that’s why it tastes so bad.
Now, obviously you can avoid this whole issue if you just wait a few minutes before breakfast. Or you can brush AFTER you eat.
Just keep in mind, you’re supposed to wait 30 minutes to brush if you’ve had citrus, or it can damage your enamel.
