RAINBOW teeth are the latest craze sweeping Instagram giving beauty fans more to smile about as they ditch whitening for bold colours.

For around £15 fashion followers can glam up their grin with the new trend which turns teeth all hues such as Sunshine, Fairy Dust, Mint and Pretty in Pink.

Working just like nail polish the multicolour mouth flair is formulated to stay on for up to 24 hours.

It can even stand up to eating and drinking and to remove it fashion fans simply need to brush with toothpaste.

David Silverstein, creator of Chrom temporary tooth polish, told The New York Post: “We see this becoming commonplace — everything from a club vibe to an everyday workplace fashion accent."

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

Rainbow teeth expert Silverstein says the tinted grins are already big on the festival scene and is even coming out with a glitter line.

The product’s solvent is said to be made from a grain alcohol base and that the pigments, similar to food coloring, are compliant with the Food, Drug, and Cosmetics Act in the US.

David added: “It doesn’t stain your teeth, and it’s not permanent."
