More than 50 systemic health conditions — including Alzheimer’s, diabetes, and heart disease — are associated with oral disease. The link between systemic and oral conditions is always microbial, inflammatory, or both. So, how can we look after our gums to improve our health? In today’s episode, Jonathan and Prof. Alp Kantarci pose the question: How does the health of your oral cavity shape your general health? Dr. Alp Kantarci is a professor, scientist, dentist, oral health researcher, periodontist, dental implant surgeon, and senior member of staff at the Forsyth Institute, an independent research institute that focuses on the connections between oral health and overall wellness. Dr. Kantarci is also a faculty member at Harvard University School of Dental Medicine. He has published more than 190 articles in peer-reviewed scientific journals and has presented more than 170 talks and posters at dental and medical congresses.
