Dark-colored stains on teeth are frustrating. Some TikTok users have the answer: Use a Mr. Clean Magic Eraser to clean your teeth. But this latest trend is not one to try at home, for several reasons. 

Certified specialist in poison information Jean Hammack, RN, is one of the poison experts at the Nebraska Regional Poison Center. "We do get calls where a toddler will bite into these sponges. One of the risks is a choking hazard," Hammack says. "These cleaning sponges also contain chemicals that would be irritating to the stomach."

"If you're intentionally using the Magic Eraser for teeth whitening, you'd be at risk for irritating your mouth, teeth and gumline. It really should be avoided," she cautions.

Safer alternatives

Dentist Amir Farhangpour, DDS, agrees that you're better off using safer alternatives. Dr. Farhangpour says, "Magic Eraser may be a good stain remover for your stove, your sink or your walls, but not on your teeth."

"There are many reasons that our teeth can be discolored," explains Dr. Farhangpour. "On a healthy tooth, extrinsic stains (what is stuck on the outside of the tooth) are just one of the reasons for a darker tooth appearance. Usually, diet and lack of regular brushing are the culprits for that."

Avoiding stained teeth can be as simple as prevention: limit red wine, coffee, tea and berries for whiter teeth. And if you need professional cleaning, make an appointment at the UNMC Omaha Dental Clinic.
