Is it OK to Postpone My Child's Orthodontic Treatment?
Until the economy brightens, some parents are postponing their children’s orthodontics. Several experts, including Dr. Raymond George Sr., the president of the American Association of Orthodontists, were asked which problems need immediate action.
WHERE TIME IS OF THE ESSENCE:
OVERJET
When the top teeth flare outward, represents a “risk of trauma,” said Dr. David Cordes, who teaches at the University of Connecticut School of Dental Medicine. If children fall or are hit with a ball and crack a tooth, then a root canal and a crown may be required.
MILD TO MODERATE UNDERBITE
When the bottom jaw is out in front of the upper, it’s a skeletal problem that’s correctable with braces at 7 or 8 years old, said Dr. Benjamin Burris of Arkansas. But if you wait until your child is older, jaw surgery could be in store.
IMPACTED TEETH
Losing baby teeth early can cause back teeth to drift into spots where adult teeth are meant to come in. Then they become impacted. Braces can create room for those teeth to grow out, Dr. George said.
CASES WHERE WAITING WON’T HURT
Parents often ask Dr. Burris if their child needs orthodontics. “Orthodontics is not a need,” he tells them. “Food, shelter, those are needs. Orthodontics, by and large, is a want.” Dr. Cordes said mild cases don’t demand quick action if they are cosmetic rather than trauma risk, or a functional issue where chewing is troublesome.

Science is One Step Closer to Growing Replacement Teeth
Re-searchers used stem cells to
grow a replacement tooth for
an adult mouse, the first time
scientists have developed a fully
functioning three-dimensional
organ replacement, according to
a report in the Proceedings of
the National Academy of Sci-
ences. The researchers at the
Tokyo University of Science cre-
ated a set of cells that con-
tained genetic instructions to
build a tooth, and then im-
planted this "tooth germ" into
the mouse's empty tooth
socket. The tooth grew out of
the socket and through the
gums, as a natural tooth would.
Once the engineered tooth ma-
tured, after 11 weeks, it had a
similar shape, hardness and re-
sponse to pain or stress as a
natural tooth, and worked
equally well for chewing. The re-
searchers suggested that using
similar techniques in humans
could restore function to pa-
tients with organ failure.
