Fillings could be consigned to history after scientists discovered that a drug already trialled in Alzheimer’s patients can encourage tooth regrowth and repair cavities.

Researchers at King’s College London found that the drug Tideglusib stimulates the stem cells contained in the pulp of teeth so that they generate new dentine – the mineralised material under the enamel.

Scientists showed it is possible to soak a small biodegradable sponge with the drug and insert it into a cavity, where it triggers the growth of dentine and repairs the damage within six weeks.

The tiny sponges are made out of collagen so they melt away over time, leaving only the repaired tooth.
