166 - Oral health, best hygiene practices, & relationship between oral health and systemic disease
Summary

In this podcast episode, Peter Etia interviews Pat, a specialist in periodontics and implant dentistry, about the importance of oral health and dentistry. They discuss the anatomy of teeth, including the enamel, dentin, and pulp, and the importance of preserving teeth for their specific functions. The conversation touches on personal experiences with dental care and the importance of regular check-ups. They also discuss the highly innervated pulp and its function in preserving blood flow and connecting with the immune response to fight against infection and inflammation.

The hosts discuss a study they conducted on twins to understand the effects of flossing on the microbiome of the mouth. The study found that sugar is the main cause of dental caries, as bacteria metabolize sugar to produce acids that destroy the enamel. The speaker discusses the importance of oral hygiene and how it has evolved over time. The modern diet, which is high in sugar, has made oral hygiene more important than ever. The speaker is conducting a clinical trial to prove the benefits of an intense oral care program for cancer patients undergoing radiation treatment, as they are at a greater risk of systemic infections due to their weakened immune system and the loss of immune barrier in the mouth.

The context discusses the signs of inflammation and infection in teeth, particularly the sensitivity to hot and cold temperatures. The controversy around root canals is discussed, with some claiming that they are hazardous and can lead to cancer and other diseases. However, there is no evidence to support these claims, and most root canals are done under a microscope today, ensuring that they are well done and have minimal complications. The pseudoscience surrounding root canals is criticized for causing unnecessary fear and anxiety in patients.

The context discusses the relationship between poor oral health and systemic diseases such as cardiovascular disease, diabetes, and Alzheimer's disease. While there is a lot of research showing an association between periodontal disease and these systemic diseases, the only way to establish causality is through clinical trials. The lack of attention given to oral health by doctors is highlighted, particularly in the context of COVID-19, where the virus can be transmitted through saliva.

The speaker discusses various dental hygiene practices and their effectiveness. They recommend using fluoride varnish to prevent decay, especially for those who are highly susceptible. They also emphasize the importance of brushing before bed and flossing regularly, as flossing is more important than brushing for preventing inflammation and systemic health issues. The speaker notes that there is no research to support the use of oil pulling, but tongue scraping with toothpaste can be effective. They recommend using the type of dental floss that is most comfortable for the individual, and using a water pick in addition to brushing, but not as a substitute. Finally, the speaker notes that using toothpicks is not harmful and may even stimulate the gums.

Overall, the conversation emphasizes the importance of maintaining good oral health to preserve overall health. The hosts discuss various aspects of oral hygiene, including the anatomy of teeth, the importance of oral hygiene, and the relationship between poor oral health and systemic diseases. They also discuss various dental hygiene practices and their effectiveness, and recommend using fluoride varnish to prevent decay, brushing before bed, and flossing regularly.
