Most people who grind their teeth do so unconsciously and chronically while they sleep. If the teeth grinding is only on occasion, it usually not a reason for concern, anyone who experiences habitual teeth grinding should consider seeking treatment. Habitual teeth grinding apply excessive force on the teeth and jaw joints. This causes erosion on the tooth enamel, as well as the joints and muscles within the jaw. Teeth grinding can lead to an array of severe problems, including damaged or broken teeth, headaches, as well as neck and jaw pain.
