But scientists have found that coconut could help fight the main bug behind tooth decay.
Scientists tested coconut oil against Streptococcus mutans a sugar-loving bacterium that clings to teeth and produces acid causing them to rot.

It paves the way for toothpastes and mouthwashes containing coconut as an active ingredient.
