Throughout his career, Dr. Wentzel became increasingly aware of a growing number of adult patients suffering from nighttime grinding, tooth wear, jaw pain, headaches, and related symptoms. Traditional soft splints offered temporary relief but did little to address the underlying causes. Driven to understand the root of these problems, he pursued extensive postgraduate training with leading organisations and clinicians, including the British Society for Occlusal Studies (BSOS), physiotherapy for TMD, TMD management with retired orthodontist Patrick Grossman, Acupuncture for dentists, the British Society of Integrated Dentistry, short-term adult orthodontics, and the British Society of Dental Sleep Medicine, among others.

His clinical curiosity deepened further when he recognised the substantial overlap between dental symptoms and conditions such as GERD, airway dysfunction, and sleep-disordered breathing.

A year-long programme in Dental Sleep Medicine proved to be a turning point. It was here that she discovered how profoundly sleep and breathing issues affect the entire body, with the teeth representing only a small part of a much larger picture.

Dr. Wentzel practices with a holistic, airway-centred approach — viewing dental health not in isolation, but as part of a complex system shaped by breathing, sleep, growth, posture, and early childhood development. His work reflects a lifelong commitment to learning, integrating science, compassion, and whole-body dentistry to help patients achieve long-term health rather than temporary symptom relief.
