New materials protect sensitive teeth for a long time

Sensitive teeth are the result of erosion of tooth enamel (or dentin), exposing tiny neural tubes in the crowns , making us feel sensitive when exposed to hot food or drinks. cold.

How to cure sensitive teeth of new materials.

This condition affects 20% of adults and it usually occurs in people aged 40-50 years. The good news is that scientists at Taiwan National University have just developed a new material capable of protecting the worn-out hard enamel.

New materials include a mixture of calcium carbonate (CaCO ₃ ) and silicate (also called dental cement). When the mixture is put into damaged teeth and mixed with phosphoric acid, it forms crystals on the enamel and seals the broken tooth.

Professor Chun-Pin Lin said that the crystals continue to penetrate into the neural tubes, so that the enamel protection layer can be maintained for a long time. Test results of new materials on dog teeth show that this method protects teeth more effectively than other sensitive dental treatments. Furthermore, this layer of material lasts up to 70 days, so it is better than toothpaste dedicated to sensitive teeth.

Experts hope the new material can also be used to treat minor lesions due to tooth decay or to help relieve pain from cracks and teeth.
