Bret Weinstein & Mike Mew: Evolutionary Dentistry & The Roots of Malocclusion

The Failure of Modern Dentistry

• 🎯 Dr. Mike Mew, a prominent orthodontist, discusses the evolutionary perspective on dentistry, highlighting a significant gap in understanding the etiology (cause) of dental problems.
• 💡 The traditional narrative of genetics causing crooked teeth is questioned, with evidence suggesting environmental factors and changes in human behavior are the primary drivers.
• ⚠️ Standard dental and orthodontic practices are criticized for potentially causing harm through treatments that don't address the root causes.

Malocclusion: Causes and Consequences

• 📉 A drastic shift from a tough, low-calorie diet to a soft, calorie-rich diet has reduced the usage of chewing muscles, leading to weaker jaws and facial structures.
• 🌬️ Concurrently, changes in posture, particularly mouth breathing due to nasal congestion, have led to a narrowing and shortening of the face, reducing space for teeth and the airway.
• 😴 This facial distortion is linked to serious health issues like sleep apnea, cardiovascular disease, diabetes, and cognitive impairment.
• 🧠 The speaker posits that this facial structure change may also constrict the carotid sheath, potentially linking to conditions like Alzheimer's and acne.

Root Resorption and Orthodontic Treatment

• 🦷 Root resorption, where the tooth root dissolves, is presented as a common consequence of aggressive orthodontic treatment, where braces artificially dictate tooth position.
• 🦴 The natural mechanism of teeth being anchored by a periodontal membrane, allowing for slight movement and self-correction, is disrupted by braces, potentially leading to root dissolution.
• ⏳ The process of moving teeth through bone may expend a tooth's capacity for cellular replacement, potentially linked to telomere length and long-term tooth health.

Reforming Dental Practices

• 🔬 There's a critique of the lack of theorists in medicine and dentistry, with an over-reliance on expensive experiments that may not address fundamental questions.
• 🏛️ Economic incentives and institutional inertia prevent a necessary 180-degree turn in dental and orthodontic practices, despite evidence of harm.
• 💡 The importance of evolutionary medicine is stressed, suggesting that many chronic conditions stem from a mismatch between our evolved biology and modern lifestyles.

Behavioral Changes for Healthier Faces

• 🚶‍♀️ Simple behavioral changes, such as standing straight, closing the mouth, chewing tough foods, and proper swallowing, are crucial for facial development.
• 🛏️ The suggestion of sleeping on a harder surface, like the floor, is proposed as a way to encourage better spinal alignment and reduce facial distortion.
• 🍎 Practices like baby-led weaning are encouraged to promote proper chewing mechanics from infancy, transitioning from infantile suckling to an adult swallow.
