Chances are you're using way too much toothpaste! On commercials they always load up the tooth brush with a huge dollop of toothpaste, complete with the little swoop tip at the end. Well according to at least one dentist that is not good for your teeth...and your tooth enamel specifically.
A dentist up in Toronto, Canada named Dr. K. Sarvendran made a TikTok video that has since gone viral, and in it she warns that we're probably using too much toothpaste, and she says it can be really bad for your teeth.
As she squeezes a large amount of toothpaste all across a brush she said, “This is how much toothpaste they show you in the commercials - not necessary at all" Dr. Sarvendran says a pea-sized amount is plenty for adults, even less for kids under 3.
In fact, research has shown that abrasives found in toothpaste can wear down the enamel on your teeth. You should also brush gently, because brushing too hard can have the same effect.
