Bruxism is the involuntary clenching or grinding of teeth, often during sleep and frequently driven by stress. Tell-tale signs include a sore jaw in the morning, worn or flattened teeth, headaches, and increased sensitivity.
Left unchecked, grinding can crack teeth and strain the jaw joint. A custom night guard cushions the teeth, and managing stress helps at the source. If you wake with jaw tension, mention it at your next visit.
