In China, a new formula made with green tea extract can help sensitive teeth sufferers as well as prevent cavities. Green tea extract epigallocatechin-3-gallate (EGCG) was found to fight against tooth erosion and abrasive brushing and even prevent biofilm formation. Researchers took nano-hydroxyapatite and EGCG and combined them with mineral silica nanoparticles, which help prevent acid wear and tear, to create the paste that strengthened teeth enamel, acted as a natural breath freshener, and prevented sugary materials from sticking to the teeth. This new formula could help those with teeth sensitivities since it protected the tooth’s enamel layer and dentin that often are eroded and cause the pain associated with sensitivity to hot or cold items.
