I am going to take a chance and say that very few people enjoy going to the dentist, especially for a filling. A dentist usually treats a cavity by removing the damaged part of the tooth. Then they fill the hole with porcelain or a combination of silver and other metals. Oftentimes fillings need replaced during the patient’s lifetime. But is filling the cavity with a foreign material really the best treatment? What if the tooth could repair itself with its own material dentine? That is what researchers at King's College London are studying. They have found a process that may replace the traditional method. Researchers say they may be close to perfecting a method of helping teeth to repair themselves. They say the treatment may make the filling of a cavity a thing of the past.
