LONDON: Scientists have developed materials that help dental enamel regenerate, and could be used to prevent and treat tooth decay or sensitivity.

Enamel, located on the outer part of our teeth, is the hardest tissue in the body and enables our teeth to function for a large part of our lifetime despite biting forces, exposure to acidic foods and drinks and extreme temperatures.

This remarkable performance results from its highly organised structure.

However, unlike other tissues of the body, enamel cannot regenerate once it is lost, which can lead to pain and tooth loss. These problems affect more than 50 per cent of the world’s population and so finding ways to recreate enamel has long been a major need in dentistry.

The study, published in the journal Nature Communications, shows that the approach can create materials with remarkable precision and order that look and behave like dental enamel.

The materials could be used for a wide variety of dental complications such as…
