It helps to know that there are three main diseases that negatively affect teeth: decay/cavities, periodontal disease, and occlusal disease. Most people are familiar with the first two, but occlusal disease — the pushing of teeth against each other — is one that people aren’t familiar with.
Occlusal Disease: The pushing of teeth against each other.
Occlusal disease is a destructive process evident in any part of the mouth, including the jaw joint, muscles, periodontium or teeth. It results from a bite in which the teeth are not properly aligned.
When the teeth are properly aligned, they work in harmony with the muscles, and jaw joint (TMJ) to withstand the force of your bite. But when there is an improperly aligned bite, this imbalance can cause problems with the teeth, muscles, jaw joint, or a combination of all three.
