The trend is a lot less harmful than other TikTok dental “hacks” that have come before it — like using a nail file to shave down your teeth or using elastic bands to close a gap tooth or making DIY fake teeth with melted plastic — but nonetheless still could cause damage.
While putting toothpaste and mouthwash into a clear container certainly makes for a prettier-looking bathroom, there’s a reason why toothpaste isn’t sold in clear packaging. According to Dr. Suhail Mohiuddin’s TikTok, “the ingredients of toothpaste aren’t UV-stable so exposing them to light can make them ineffective.”
“Every time I see this, I [think], if this worked they would have pushed this already,” a commenter on Dr. Mohiuddin’s TikTok said. “Something isn’t right.”
“Why do people want to go through so much work to fix something that isn’t broken?” another person lamented.
Regardless of how much free time you have or whether you think you’ve outsmarted capitalism with this DIY hack, dentists do not recommend trying it.
“You really shouldn’t be putting your toothpaste in a clear container,” Dr. Amber Bonnaig told In The Know. “The thing about a tube of toothpaste is it’s kind of been one of those things that have been refined for many, many years to make sure as far as like the materials inside are at the right proportions. I just think that’s just something to stay away from.”
