Three key takeaways from ‘Licensed to Thrive’

1Whether you are sick or healthy is largely determined by your mouth

‘Licensed to Thrive’ delivers a compelling message about the vital role that your mouth plays in determining your state of health. Dr. Felix Liao’s book serves as a call to recognise the mouth’s significance as a powerful driver of well-being or illness. He explicates how a well-maintained mouth has the potential to bolster your body’s defences, minimise inflammation, and stave off the typical issues that arise with advancing age.

The author cites various studies that prove that poor oral health can exacerbate sleep quality, eating habits and inflammation. Dr. Liao also provides examples of how impaired mouth structure and style can lead to chronic diseases.

2Poor mouth health can trigger inflammations that contribute to chronic disease

The book vividly elucidates the connection between mouth health and inflammation. Inflammation, often triggered by oral infections, can have far-reaching effects on the body and make it more susceptible to a long list of diseases, including heart conditions, cancer, diabetes, obesity, inflammatory bowel disease, asthma and many others. This interconnectedness underscores the importance of biological dentistry, focusing on holistic mouth solutions to enhance oral health and overall wellness. Adopting a proactive approach to improving oral health as an integral part of overall wellness can contribute to reducing inflammation, promoting immunity, and enhancing well-being.

3Your mouth health defines how your body will grow and develop from the moment you are born

Beginning from infancy, our growth and development are guided by the mouth’s role. The book emphasises that underdeveloped jaws can lead to widespread health issues. The concept of Impaired Mouth Syndrome underscores how compromised oral health can impact broader head functions. Notably, addressing oral health conditions like obstructive sleep apnea in children can positively affect oral-facial growth. The author introduces epigenetic oral appliance therapy as a non-invasive method to reshape jaws and airways, improving sleep quality and relieving pain. With a focus on healthy natural teeth, the therapy aims to restore oral functions and enhance overall well-being. The book also highlights the connection between mouth structure, airway obstruction, and various symptoms, such as pain, fatigue, and mood disturbances. By prioritising proper alignment, breathing, circulation, and digestion, individuals can uncover the path to thriving health and vitality.

Best quotes from ‘Licensed to Thrive’

“Inflammation is the major driver of human disease. It damages your heart, your brain, your kidneys, your gut. Poor-quality sleep, especially sleep apnea, creates a persistent inflammatory state in your body.”

“Cancer, or any illness, is an outcome. Prognosis is poor if your liver gets “direct deposits” from colon cancer. When should you take control of the source? What are the causes? Among the many, there’s no denying that oral contributions are big. For example, this 2012 study2 found cancer death rate goes up 4.8 times with severe sleep apnea and 2 times with moderate sleep apnea.”

“Biomimetic oral appliance therapy may be a useful method of managing severe cases of OSA (obstructive sleep apnea) in adults, and represents an alternative to CPAP and MADs.”

Final takeaway
