The dentist’s drill could become obsolete in as little as three years.

A new plasma jet device could replace the dentist’s drill in as little as three years, it has been claimed.

A study carried out by researchers in Germany has highlighted the benefits of using such a device for treatments, as it would be non-invasive and practically pain-free.

Lead researcher Dr Stefan Rupf from Saarland University in Homburg said: “The low temperature means they can kill the microbes while preserving the tooth.”

He added the dental pulp at the centre of the tooth is linked to the blood supply and nerves. Therefore, heat damage to it must be avoided at all costs in order to save the tooth.

Elsewhere, Indian Express recently reported more people are choosing to have dental implants fitted rather than having a bridge if they lose a tooth.

The publication noted the procedure can provide a more permanent and aesthetically pleasing solution to replacing a missing tooth.
