First there were grillz, fangs, and then came the oddity of tooth tattoos. But just when you think you’ve seen it all, a US company goes and releases a dental dye.

Just like nail polish, Chrom's tooth polish can be applied in a matter of seconds and can last for up to 24 hours.

“It doesn’t smudge when you're eating and has no taste, so it won’t mess up your brunch plans,” the company says on its official website.

Their thinking behind the brand is that why would you want to have pearly whites when you can accessorize your smile bones with just about any colour? “After all, makeup isn’t for fitting in, it’s for standing out.”

If you think the trend is one of the wackiest you’ve seen this year, you’ll be even more weirded out by the fact that it has its own hashtag #toothpolish. And like any trend that finds its way onto social media, it’s been embraced by the “fashion-forward” crowd.

But before you go rushing out to accentuate your outfit with your rainbow teeth, it’s going to cost you anything from R300 a tube.

Currently, you can choose from 10 colours, including Candy Floss and Fairy Dust. And, according to company founder David Silverstein, plans are afoot to develop a glitter line as well.

“We see this becoming commonplace - everything from a club vibe to an everyday workplace fashion accent,” Silverstein told Fox News. He’s even touted tooth paint as the next best thing you’ll see at popular music festivals.

And don’t go thinking that it tastes like toothpaste. According to the Daily Mail, each tube is made with a grain alcohol base and pigments that are similar to food colouring which the brand says was created by dentists.

But not all dentists are on board.

Dr Ramin Tabib from NYC Smile Design, said the tooth polish was “interesting to say the least” but stopped short when it came to safety.

“I have no idea what’s in this product and the safety long term,” he told Seems like the company does not want to give the ingredients out and they are calling it proprietary.

“If I am putting something like this over my teeth which is basically ingested, I would need to know what what exactly I am putting in my body.”
