We’ve all brushed our teeth like upstanding citizens, and then take a sip of orange juice, which of course we immediately regret! Drinking orange juice after brushing your teeth is a universal disgust. It’s understood that orange juice and toothpaste just don’t mix — but does anyone know why?
How Do Tastebuds Work?
You tongue can detect different tastes. In fact, we have 10,000 taste buds in our mouth. It detects salty, sweet, sour, bitter and umami. All of these basic tastes work together to form flavour.
Why Toothpaste Makes Orange Juice Taste Bad?
When you brush your teeth, the toothpaste becomes foamy and bubbly, making your teeth feel clean. The foam is made by a ingrediant called sodium lauryl sulphate (SLS). While SLS helps foam up the toothpaste, SLS also suppresses our sweet taste buds. So the toothpaste hides the sweetness of orange juice and makes it taste bitterer.
Now you know why certain things taste really gross after you brush your teeth. SLS is in a wide range of products, so next time you’re at the store on the toothpaste aisle, look for Sodium Lauryl Sulfate on the ingredient label for fun.
