People may think that rinsing their mouths after brushing their teeth might be the healthiest thing to do. Rinsing your mouth out after brushing your teeth isn’t a good idea afterall.

Lifehacker.com has found out from Redditor giubaloo who explains why.

“I know this is not common practice, but it is actually quite important! Fluoride, one of the active ingredients in toothpaste, doesn’t spend much time in contact with your teeth when you are brushing. Thus, it is crucial to let it work after you have already brushed your teeth.”

According to dentist Dr Phil Stemmer, from The Fresh Breath Centre in London: “Rinsing washes away the protective flouride coating left by the toothpaste, which would otherwise add hours of protection. If you are thirsty drink a glass of water before brushing your teeth,” the website quoted Stemmer.

Here is an advice for people who would want to rinse their mouth out, they can pick up a fluoride rinse and just use that afterwards instead of water.
