Night guards are primarily used to address the problem of teeth grinding or clenching, also known as bruxism. These habits can occur during sleep and can lead to various dental issues such as tooth wear, tooth fractures, jaw pain, headaches, and damage to dental restorations. Night guards act as a protective barrier, cushioning the teeth and reducing the negative effects of bruxism.
Night guards create a physical barrier between the upper and lower teeth, preventing them from grinding against each other. By absorbing the forces generated during grinding or clenching, night guards help distribute the pressure evenly, reducing the risk of tooth damage. They can help preserve the tooth structure and prevent excessive wear or fractures caused by bruxism.
