For all those who fear a trip to the dentist, fear no more - perhaps.
Two researchers claim to have found a chemical that would make teeth cavity proof - and perhaps do away with trips to the dentist.
Two dentists in Chile are behind the discovery, which they're calling Keep 32, a reference to the number of teeth in a person's mouth.
The chemical works by wiping out bacteria that cause cavities - in just 60 seconds.
Keep 32 could be added to dental care products including toothpaste, mouthwash and chewing gum.
The chemical has been tested for the past seven years but is only now going into human trials.
Researchers José Córdoba from Yale University and Erich Astudillo from the University of Chile said Keep 32 could be on the market in about 18 months.
