Forget about flashing your pearly whites this holiday season: rainbow-colored teeth are in, apparently.

The latest offbeat beauty trend is for teeth that have been painted a colourful hue, such as pink, green, or even metallic copper, thanks to the launch of Chrom Temporary Tooth Polish. Indeed, the product can be used to color in the entire mouth, or just highlight one or two ’accent teeth.’ The formula, which lasts for up to 24 hours but can be removed in seconds, claims to be both smudge-free and taste-free, and comes in ten vibrant shades.

"We see this becoming commonplace - everything from a club vibe to an everyday workplace fashion accent," the brand’s creator, David Silverstein, told the New York Post. He added: "Perhaps you go to work with one tooth [that] matches your nail polish or your hair color."
