Causes of Night Grinding (Bruxism)

What causes night grinding?

Night grinding, or bruxism, is very common; what is unusual is that many people have no idea they are doing it. Often, the first knowledge of the night grinding or clenching of teeth is when a partner reveals that you are gnashing away in your sleep! There are two main causes; malocclusion, which is where your teeth do not meet properly or, stress related illnesses. The idea that teeth poorly meeting causes night grinding is not one all dentists agree on. However, for some, having their teeth properly aligned does reduce the night grinding.  The most supported theory is that night grinding is a way to release tension, caused by the stresses of the day..
