This research is expected to advance the development of “tooth regenerative therapy,” which may one day allow doctors to replace diseased or damaged teeth with bioengineered teeth grown from stem cells such as induced pluripotent stem (iPS) cells. This type of treatment could ultimately eliminate the need for dentures and false teeth.
