October 18 marks this year's Double Ninth Festival, also known as Chongyang Festival, a traditional Chinese occasion to show respect and care for older people, and a reminder that healthy aging is about more than adding years to life.

A crucial, yet often overlooked, part of healthy aging is oral health. In this episode of Health Talk, Dr. Wang Dongqing, a periodontist at Beijing Stomatological Hospital of Capital Medical University, explains why healthy teeth and gums matter far beyond a confident smile.

Periodontitis can affect chewing, nutrition and quality of life, and its associated inflammation and infection may also be linked to cognitive and cardiovascular health.

From regular dental checkups to proper oral care and healthy lifestyle habits, taking care of our teeth is one simple way to support a healthier, more active later life.
