Discover the fascinating link between tea drinking and dental health in our latest exploration. Delving into recent research, we unveil how different types of tea, from the robust flavors of black tea to the delicate notes of green tea, play a role in maintaining a healthy set of teeth among the elderly. It turns out, your choice of tea could be doing more than just pleasing your palate; it could be a key player in keeping your smile bright.
In a groundbreaking study analyzing over 6,000 seniors, scientists found a remarkable association between tea consumption and the number of teeth remaining in old age. For men, sipping on green tea regularly was linked to better dental health, while women who preferred black tea showcased a similar benefit. The study highlights not just the type of tea but also the importance of consistent dental hygiene practices, such as daily brushing, in amplifying these positive effects.
This research isn't just about keeping your teeth into your golden years; it's a testament to the broader health implications of our daily habits. By choosing certain teas and maintaining good oral hygiene, we could be taking simple yet effective steps towards longevity and wellness.

Association between tea types and number of teeth: a cross-sectional study of the Chinese Longitudinal Healthy Longevity Survey
Published in BMC Public Health.Zheqi Huang et al.
Abstract
Background: Previous studies have suggested that tea consumption may have a positive impact on oral health. However, the effects of different tea types on oral health remain unclear. Therefore, this study aimed to determine the association between residual teeth and consumption habits of different types of tea (green tea, black tea, oolong tea, and scented tea) in older adults.
Methods: We conducted a secondary analysis using data from the Chinese Longitudinal Healthy Longevity Survey in 2018. In a sample of 6,387 older adults, we performed logistic regression analysis to examine the relationship between persistent tea consumption and oral health according to sex and brushing frequency. The indices for particularly healthy oral health and relative health were set at more than 20 teeth and more than 10 teeth, respectively.
Results: The study included 2,725 males and 3,662 females, both aged 65 and older. Among individuals with more than 20 teeth, drinking green tea significantly improved oral health in men (adjusted odds ratio [ORs]: 1.377; 95% confidence interval [CI]: 1.082-1.752) and drinking black tea significantly improved the oral health of women (ORs: 2.349, 95%CI: 1.028-5.366). In the daily brushing group, green tea had a significant beneficial effect on increasing the number of teeth in men and black tea had a significant beneficial effect in women. Among individuals with more than 10 teeth, drinking green tea significantly improved oral health in men (ORs: 1.539; 95% CI: 1.209-1.959) and drinking green tea and scented tea significantly improved the oral health of women (ORs: 1.447, 95%CI: 1.052-1.991; ORs: 1.948, 95%CI: 1.137-3.340). In the daily brushing group, consumption of green tea and black tea had significant beneficial effects on increasing the number of teeth in men, whereas that of green tea, black tea, and scented tea had significant beneficial effects in women.
Conclusion: Long-term green tea consumption in males and black tea consumption in females were significantly associated with maintaining functional dentition (≥20 teeth). Similarly, long-term green tea consumption in males and green tea and scented tea consumption in females were associated with avoiding severe tooth loss (≥10 teeth). Furthermore, in the daily tooth brushing group, long-term consumption of black tea was associated with avoiding severe tooth loss in both sexes. However, tea consumption alone had no effect on oral health without good brushing habits.
