A team of researchers from Japan have developed a way to fill cavities without having to go under the drill.

A paste made from a substance that is molecularly similar to tooth enamel has been developed and will soon be available at your dentist’s office, offering an opportunity for people who cry at the very idea of getting their teeth drilled and filled a chance to shed tears of joy—and maybe even alleviate some of that dentist-related anxiety.

The researchers, who developed this groundbreaking cavity-filling method, headed by Kazue Yamagishi, created and tested a substance that is nearly identical to natural tooth enamel.

Their findings were astonishing: cavities filled with the pseudo-enamel paste were just as sturdy and stable as their metal or amalgam counterparts (amalgam fillings are controversial), if not more so.

The faux enamel paste allows for more efficient filling, as the cavity can be filled without the need to cut out part of a healthy tooth in order to reduce the chances of the spread of decay. The paste bonds with the tooth without the need for drilling, saving the tooth’s owner time and pain.

It should be noted that this paste is suitable for cavities in their early stages.

Although it would be nice if we could become our own dentists, because the synthetic enamel is extremely acidic, professional application of the paste by a dentist is required.

Its acidity and high concentration of hydrogen peroxide could cause inflammation of the gums, say the researchers. Other materials with similarly aggravating potential are already used on patients, they note.
