Drinking OJ After Brushing Your Teeth Is Nasty! I Found Out Why!

I know it’s happened to me.  You brush those pearly whites and grab a drink of orange juice as you head out the door…then…oh my yuck!  Nasty!  The worst taste in the world!  But why?  I’ve always wondered and decided to find some answers!

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.

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.

So, now we know!

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.
