Do you suffer from sensitive teeth? This green tea extract may help

If your teeth are highly sensitive to that hot or cold drink, researchers have developed a new formula made with an extract from green tea that can fix this problem.

If your teeth are highly sensitive to that hot or cold drink, then here’s a good news as researchers have developed a new formula made with an extract from green tea that can fix this problem as well as help prevent cavities. The findings indicated that green tea extract epigallocatechin-3-gallate (EGCG) stood up to tooth erosion, abrasive brushing and prevented biofilm formation.

When the protective layers of teeth are worn away, a bony tissue called dentin is exposed. This tissue contains microscopic hollow tubes that, when exposed, allow hot and cold liquids and food to contact the underlying nerve endings in the teeth, causing pain. Unprotected dentin is also vulnerable to cavity formation.

Cui Huang from Wuhan University in China and colleagues wanted to tackle sensitivity and beat the bacteria at the same time. They took nanohydroxyapatite and EGCG - which has been shown to fight streptococcus mutans, which forms biofilms that cause cavities.

These ingredients were combined with the mineral silica nanoparticles, which can stand up to acid and wear and tear. They tested this on extracted wisdom teeth and found that the formula plugged the dentin tubules.
