The dentist's drill could be a thing of the past!

Scientists have created a solution that mimics the way the body forms new teeth - allowing natural repairs of holes without the need for drilling and filling.

Oral hygiene experts at Leeds Dental Institute have also made a mouthwash that kills plaque-making bacteria when a light is shone into the mouth.

They believed the new liquid could be available in less than three years - and perform the same job as using a toothbrush.

The drilling alternative that uses a protein to naturally repair holes on the tooth's enamel, could be ready for patients within five years.

The compound works by attracting minerals that form enamel in the same way as the body creates teeth.

The chemical can be painted on teeth in small holes to prevent them decaying and becoming larger. The same treatment can be used to fill in tiny holes in teeth that cause them to become sensitive to hot and cold food and drinks.
