Occlusion
What is occlusion?
Mother nature didn't provide all of us with a stable, healthy
bite. Some people have bites that have been affected by wear, changed by dental
restorations, or that have shifted with time.
A healthy bite allows all of your teeth to hit simultaneously and evenly when
your jaw joint is
seated into its proper position at the base of your skull. In this position,
your chewing muscles are also contracting evenly. One way to test your bite is
to shift your jaw to the side. Your canine teeth, or eye teeth, should be the
only teeth hitting and should absorb all the lateral biting force.
A "bad bite"
When you have a bad bite, also called a malocclusion, your teeth
do not align properly. This can cause
I damage to your teeth and restorations, and it can also set off a cycle of
muscle spasms, pain, and soreness commonly referred to
as TMD, or temporomandibular disorder.
When the balance is lost among the bones, cartilage, and muscles of the
temporomandibular joint, it can lead to:
- Headaches Earaches
- Difficulty in opening and closing the jaw
- Clicking or popping in the joint
- A dull, aching pain around the ear that spreads into the face
- Sore or painful jaw muscles
Bite problems can cause bruxism and abfraction
A malocclusion can also cause a condition called bruxism,which
is the clenching or grinding of the teeth that occurs primarily while sleeping.
The symptoms of bruxism are worn teeth, notching at the gumline (called
abfraction), as well as all of the symptoms associated with TMD.
Abfraction is the notching of teeth near or even under the gumline. When your
bite is slightly off, undue stress is placed on the involved teeth and they
begin to flex. This continual flexing and stress eventually cause the enamel to
separate from the inner dentin layer, forming abfraction's characteristic notch
at the gumline.
We can perform a complete bite evaluation, which will help us address any
potential problems early in their development.
Adjusting, realigning, or restoring teeth can prevent many future complications,
and can help you gain optimal muscle balance and a comfortable bite.
