Better known as a bite or night guard, an occlusal guard is a removable dental appliance used to aid in the cushioning from the impact of the teeth together. Clinching and grinding of the teeth are habits that patients have, which mostly occur while they are sleeping and most people are usually unaware they are doing this in their sleep. The results of clinching and grinding have been known to break and crack fillings and even their teeth over time. The purpose of an occlusal guard is to prevent any further or potential damage brought on by excessive clinching and grinding habits. Overall, it is a good investment to prevent further dental work from needing to be completed.
