How Malocclusion (Bad Bite) Relates To Different
Dental Problems - It is ironic that one of the most
common dental disorders is also the most neglected. The way the
teeth fit together when the jaw closes and chews is of profound
importance to the long-term health of your teeth.
If
the teeth do not meet in a proper fashion, they cause obstructions
in the normal jaw movement. These obstructing surfaces can either
loosen the teeth or may break the tooth enamel. The muscles that
move the jaw are very powerful and can do major damage to the teeth
when the biting surfaces don't fit together properly.
The
problem can be compounded if teeth interfere with functional muscle
patterns, the jaw muscles will attempt to "erase" the
part of the tooth that interferes by grinding against it all the
more. This can lead to even more severe wear or it may crack off
a cusp or split the tooth. Or it may loosen the tooth or cause it
to move out of alignment. The excessive muscle activity often results
in pain in the muscle itself. All of the jaw muscles can become
sore including the temporal muscles that are the source of many
so-called tension headaches.
Some excessive muscle activity may be caused by emotional stress.
But with some special exceptions, damage done by stress induced
grinding and clenching can be minimized to a manageable level by
equalizing the biting surfaces that are in conflict with jaw movements.
The
power of the jaw muscles may surprise you. Some people can exert
over 900 pounds of compressive force with their jaw muscles so you
can imagine how much damage such force can do when you close into
a single tooth and then work it from side to side. The effect is
very much like working a fence post loose as the bone around the
root breaks down. If you can put your finger on any tooth in your
mouth, and then squeezing your teeth together causes the tooth to
move, you can be sure that it is just a matter of time before there
will be a problem with that tooth.
Sometimes
the muscle forces that work the tooth sideways stimulates bone around
the root to build up and become stronger. When that happens, the
tooth actually bends in its socket and this creates a microscopic
chipping away close to the gum line to form a deep groove in the
tooth. This is called an abfraction. These deep grooves at the gum
line are often mistaken for toothbrush abrasion, but scientists
have shown us that the grooves are actually the results of bending
of the tooth in its socket. These grooves can lead to much sensitivity
in those teeth because the opening into the tooth exposes nerves
that can be exquisitely sensitive. Correction of the bite to remove
excessive lateral forces on the teeth in most instances either eliminates
the sensitivity completely or reduces it to a much more acceptable
level.
Patients
should be aware that much confusion surrounds the importance of
a harmonious bite, including many misconceptions that have been
fostered by flawed research that has failed to properly relate the
bite interferences to the position and condition of the temporomandibular
joints. Knowledgeable clinicians, however, are very much aware of
this relationship and can achieve excellent results in making both
your teeth and your jaw muscles more comfortable by bringing your
whole biting into harmony.
