Researchers have already successfully
re-grown mouse teeth in a lab from single mouse cells and believe the
same results can be achieved with human teeth.
The same scientists at the University of
Texas Health Science Center at San Antonio, are also looking at sharks
to see how they re-grow their teeth to see if the same can be done for
humans.
"In the next 10 years, we hope to
push the research in the direction where we could take initial tissue
from a human patient, put it in a culture dish and grow a tooth for
them," said Univ. of Texas lead researcher Dr. Mary MacDougall.
The research team are trying to find out
which human genes will induce formation of a new tooth in order to be
able to stimulate these genes within the tooth bud cells. Sharks
routinely re-grow their own teeth. "Now we are looking at repairing
a tooth at the cavity site from the bottom up by stimulating cells that
are still viable in the tooth," MacDougall said.
These new technological innovations are
still about 20 years away, according to experts who recommend keeping
good care of the teeth you already have.
