Leeds Dental Institute scientists have come up with a solution that can mimic the way the body forms new teeth, and would do away with drilling and filling by making it possible for the teeth to repair themselves.

Along with this discovery, these researchers have also formulated a mouthwash that kills the plaque causing bacteria when a light is shone into the mouth.

While the researchers hope that this mouthwash would hit the market within the next 3 years, it is believed that the alternative to drilling could be ready for use within five years.

With the drilling alternative, which is derived from a new protein, it is possible to repair holes in the enamel on the surface of the tooth naturally. It works by creating a scaffold which attracts the minerals that form enamel just like the body creates new teeth.

This substance can be painted on teeth in the early stages of tooth decay for filling up tiny holes before they become large holes full of decay.

"I can't bear the noise of the drill and it is surprising how many people say just the sound is enough to instil fear. We looked at a way to treat early decay and avoid drilling," The Telegraph quoted Prof Jennifer Kirkham, Research Director at the institute, as saying.
