Main causes for teeth grinding
No clear causes of teeth grinding have been identified. However, the following factors are closely related to this condition:
• Emotional. An overly fast pace of life, constant emotional tension and stress are among the most important causes of teeth grinding.
• Psychological. This condition is more common in people who tend to be competitive, hyperactive, aggressive or depressed, and who bottle up their anxiety and anger.
• Physiological. Grinding can be caused by an irregular occlusion, tooth loss, diseases of the oral mucosa or improperly performed restorations.
• Pharmacological. Teeth grinding is also associated with the use of certain medications or psychotropic substances as well as a deficiency of magnesium and B vitamins.
• Bad habits. Bruxism is also caused by smoking, large amounts of caffeine, excessive alcohol consumption, drugs and other harmful habits.
