Pearly whites are boring. According to one entrepreneur, rainbow teeth are where it’s at.

“We see this becoming commonplace — everything from a club vibe to an everyday workplace fashion accent,” says David Silverstein, the New York City-based brand creator of Chrom temporary tooth polish.

Chrom is a little like nail polish … only for your choppers. For around $20 a bottle, you can gussy up your grin with whimsical hues such as Sunshine, Fairy Dust, Mint and Pretty in Pink.

Granted, showing up at your morning meeting with sky-blue chompers might seem less than professional, but Silverstein sees multicolor mouth flair becoming as quotidian as tattoos.

“Perhaps you go to work with one tooth [that] matches your nail polish or your hair color,” he says.

Silverstein says rainbow grins are already big on the music festival circuit. And soon, Burning Man devotees who loved last year’s sparkly-boob trend will have even more to smile about.

“We’re actually coming out with a glitter line,” Silverstein says.

The polish is formulated to stay on for up to 24 hours and stand up to eating and drinking. To remove, simply brush with toothpaste.

Silverstein says the product’s solvent is made from a grain alcohol base and that the pigments, similar to food coloring, are compliant with the Food, Drug, and Cosmetics Act. He declined to disclose Chrom’s full ingredient list for proprietary reasons, but says the polish is “100 percent safe” and was formulated by dentists.

“It doesn’t stain your teeth, and it’s not permanent,” he says.

Long a staple in stage makeup and Halloween costumes, tooth paint for everyday use raises concerns from some dentists.

“I wouldn’t be comfortable saying [dental paint] is safe without a material safety data sheet, or MSDS, which would have a full list of ingredients,” says Dr. David Drew, a dentist in Woodridge, NY. “I would not recommend daily use without a long-term study proving its safety.”
