Some TikTok users are remodelling their crooked teeth with nail files in a viral trend that US dentists are dubbing damaging and dumb.
“You’re doing irreparable damage and destruction to your teeth,” Dr Chad Evans, co-founder of Texas-based Smile Magic Family Dental, said.
Clips on TikTok depict certain individuals attempting to fix their uneven smiles by using a nail file to sand their teeth down to size. It’s basically the bargain-bin equivalent of an enameloplasty—a reshaping procedure involving enamel removal that one would receive from a cosmetic dentist.
However, unlike professionals who know how to do the job safely, an amateur could potentially remove vital coating, causing the tooth to become hypersensitive or even die.
Dr Evans recalled one video in which a woman with a chipped tooth filed down her two front teeth to match her imperfect tooth’s length.
“Essentially, what she’s doing is she’s shortening the lifespan of her teeth,” he said.
“They are now compromised, and it’s just a matter of time before she starts developing serious issues.”
