I am trying not to use toothpaste. I use baking soda to brush my teeth. No minty taste. But as for the QOTD, once or twice.

That doesn't sound very effective unless you floss before you brush, since the sand in toothpaste is what's used to get stuff out of your teeth.

'cause the ingredient in toothpaste that helps it froth up blocks your tongue's sweet receptors. If you brush like a normal person, orange juice shouldn't taste more tangy. That would mean it tastes sweeter. It should become very bitter.
