The process of regeneration of teeth in modern medicine is impossible, but science is not standing still. American biologists have managed to run a repair of dental tissue in cichlid, freshwater fish. Teeth and taste buds they originate from the same tissue.
In the experiment, researchers observed the regeneration of dental tissue, immersing the teeth of the fish in a special solution. After 5-6 days after the start of the study were obtained the first results.
Scientists believe that picking up the right chemical signals, can start the process of restoring teeth and a person. If that ever happens, dentists will have to retrain in molecular biology, in order not to lose work.
