More than 86 percent of adults aged 20 to 39 are affected by tooth decay. This means most people have had at least one or two cavities filled in their lifetime, and probably more. A silicone-based cement is used by dentists worldwide to fill holes that remain in teeth when a dentist clears out the infected, decayed part with a drill. These dental fillings for cavities do the job, but wear and tear, as well as hard or chewy foods, can loosen them, increasing the risk of infection and decay.
