Dr. K. Sarvendran, a dentist from Toronto, Canada, has gone viral on TikTok for warning folks they are using too much toothpaste, and doing so can be bad for your teeth. “This is how much toothpaste they show you in the commercials - not necessary at all," she says, as she squeezes toothpaste all the way along her toothbrush. Instead, she insists you only need a pea-sized amount.
Apparently, studies have shown that using too much toothpaste can break down enamel because of the abrasives in its ingredients. That, along with vigorous brushing, can thin down enamel over time.
Well, Dr. Sarvendran video left many folks on TikTok shocked. "Ive been using waaaay too much then (sic)," one person noted, while another added, "Thanks for the wise advice."
