In this case, a 34-year-old patient suffering from 20 years of headaches, TMJ pain, and severe sleep disruption experienced a remarkable turnaround after eight sessions of biofeedback therapy. By restoring healthy CO₂ levels, improving parasympathetic tone, and retraining breathing patterns, the intervention resolved his jaw pain, normalized sleep, eliminated long-standing bruxism symptoms, and reduced anxiety scores from moderate to minimal.

As the author notes, “The resolution of brain fog was particularly impactful—the patient stated his mind now felt so clear that he could do the work of three people.” This case underscores a growing recognition that bruxism is not merely a dental problem but a reflection of deeper physiological stress, making HRVBF a promising tool for modern dentistry.
