What if cavities could be filled with lab-grown human enamel? Researchers
are hard at work on the very thing (12, 13). Dental surgeons already attach dentures
or crowns to artificial roots known as dental implants, and they use tissue engineering
to treat gum disease. One such tissue-generating product uses a special material
saturated with healing drugs and growth factors (naturally occurring substances
that help regulate the body's healing process) to help in the regeneration of
gum tissue. (12)
