Dr Gao took to TikTok to make the shocking revelation, and revealed how much toothpaste we should be using according to our age.
In his video, which has racked up millions of views, he said that the amount of toothpaste generally used in adverts is too much, and that a pea sized amount is plenty for adults.
He said: “The amount used in commercials is way too much.

“For ages three and below, all a smear is all you need.”
Dr Gao then put a small amount of toothpaste on a brush, saying: “For anyone older, a pea size amount is plenty.”

“Use fluoridated toothpaste containing no less than 1,000 ppm fluoride.

“Children’s tooth brushing should be supervised until at
