Good News -- End of Painful Dental Fillings in Sight

Dentists may soon be able to put away their drills. A new peptide, which can be embedded in a soft gel or a thin film and placed next to a cavity, encourages cells inside teeth to regenerate in about a month.

This could eliminate the need to fill cavities or drill into the root canal of an infected tooth.

According to Discovery News:

“Instead of a drill, a quick dab of gel or a thin film against an infected tooth could heal teeth from within ... The gel or thin film contains a peptide known as MSH, or melanocyte-stimulating hormone. Previous experiments ... showed that MSH encourages bone regeneration.  Bone and teeth are fairly similar, so the ... scientists reasoned that if the MSH were applied to teeth, it should help healing as well.”
