While daytime bruxism is often linked to stress or anxiety, nighttime bruxism (sleep bruxism) usually occurs unconsciously during sleep and may be harder to detect. Common symptoms include jaw pain, worn teeth, headaches, and sleep disruption. At Dr. Akkshaya Dental & Aesthetics, we offer personalized treatment options like custom night guards and stress management strategies to protect your smile around the clock.
