The next time you get a cavity, you might get tooth regeneration instead of fillings.
Materials scientists are beginning to develop solutions of chemicals that can actually rebuild decayed teeth. Enamel and dentin, the natural materials that make teeth the strongest pieces of your body, would replace gold or ceramic fillings.
Enamel and dentin are strong, long-lasting, and can repair themselves. However, they are also very complex.
But with the help of a calcium-containing solution of ions, scientists have been able to rebuild dentin and remineralize some parts of the teeth. Still, the complicated process is years away from being used in your local dentist’s office.
