Thumb sucking
Sucking is a
natural reflex
and infants and
young children
may use thumbs,
fingers,
pacifiers and
other objects on
which to suck.
It may make them
feel secure and
happy or provide
a sense of
security at
difficult
periods. Since
thumb sucking is
relaxing, it may
induce sleep.
Thumb sucking
that persists
beyond the
eruption of the
permanent teeth
can cause
problems with
the proper
growth of the
mouth and tooth
alignment. How
intensely a
child sucks on
fingers or
thumbs will
determine
whether or not
dental problems
may result.
Children who
rest their
thumbs passively
in their mouths
are less likely
to have
difficulty than
those who
vigorously suck
their thumbs.
Children should
cease thumb
sucking by the
time their
permanent front
teeth are ready
to erupt.
Usually,
children stop
between the ages
of two and four.
Peer pressure
causes many
school-ages
children to
stop.
Pacifies are no
substitute for
thumb sucking.
They can affect
the teeth
essentially the
same way as
sucking fingers
and thumbs.
However, use of
the pacifier can
be controlled
and modified
more easily than
the thumb or
finger habit. If
you have
concerns about
thumb sucking or
use of a
pacifier,
consult your
dentist. |
