Coffee brushing order

I was just watching the news while drinking coffee and learned something new. I always thought that drinking coffee after brushing your teeth caused staining, but it turns out that wasn't the case.

"Most common toothpastes contain fluoride, so brushing helps prevent staining or tooth discoloration by coating the teeth with fluoride," they said. "On the contrary, brushing immediately after drinking coffee can damage your teeth because the coffee acidifies them."

That's what they say, haha. Also, they recommend waiting about 20-30 minutes before brushing your teeth, so keep that in mind if you're a coffee lover like me~
