Prevent cavities in sensitive teeth
People with sensitive teeth know that taking a sip of an ice cold drink can cause a painful jolt in the mouth. There are different approaches to treat this condition but the treatment usually does not last very long. Research appearing in ACS Applied Materials & Interfaces shows the development of a new material with an extract from green tea that can help treat sensitive teeth and even help prevent cavities. Tooth sensitivity occurs when the protective layers of teeth are worn away and exposing the bony tissue called dentin. Dentin contains microscopic hollow tubes which allow hot and cold liquids and food to contact the underlying nerve endings in the teeth leading to pain. Unprotected dentin is vulnerable to having cavities form around it. Placing a mineral called nanohydroxyapatite in these tubes has often been used to treat sensitive teeth. … Read more
