Osteoporosis may significantly increase the risk of severe gum disease, highlighting the need for coordinated medical and dental care and screening. This review was recently published in the Journal of Periodontal Research.
Furthermore, this association may be due to a loss of estrogen, which can negatively impact bone metabolism, particularly in postmenopausal women, the authors wrote.
“Osteoporosis and periodontitis are linked by bidirectional relationships through shared inflammatory and bone-resorptive pathways,” wrote the study’s lead author, Dr. Jia Chang, PhD, of the University of California, Los Angeles School of Dentistry (J Periodontal Res, May 18, 2026).
The goal of the review was to evaluate epidemiological evidence connecting osteoporosis and periodontitis and investigate the clinical and biological mechanisms linking the two conditions. Researchers searched electronic databases through January 2026, focusing on epidemiological studies, systematic reviews, meta-analyses, clinical trials, and basic science research, the research team wrote.
Only peer-reviewed studies reporting original findings or summarized evidence on epidemiological associations, biological pathways, diagnostic links, or treatment implications were included. The review analyzed seven potential connections between osteoporosis and periodontitis, including microbial translocation, systemic inflammation, immune cell activity, masticatory dysfunction and diet interactions, shared risk factors, and changes in the oral microbiome.
Osteoporosis may worsen the progression of periodontitis by accelerating alveolar bone loss triggered by bacterial plaque. This effect is especially significant in postmenopausal women, as reduced estrogen levels increase inflammatory cytokines, which also contribute to periodontal tissue destruction. As a result, postmenopausal women with osteoporosis may be more likely to experience severe periodontal symptoms, including deeper periodontal pockets, greater gingival recession, and increased clinical attachment loss, they wrote.
Additionally, in a large cross-sectional study, periodontitis was linked to a 1.29-fold higher risk of osteoporosis among individuals with good oral hygiene, while poor oral hygiene increased the risk to 6.02-fold. These findings highlight the association between periodontitis and osteoporosis and suggest that maintaining good oral hygiene may reduce osteoporosis progression, while unexpected periodontal deterioration could serve as an early warning sign of osteoporosis.
However, further research may be needed to better understand the complex relationship between periodontitis and osteoporosis and to address existing gaps in underexplored areas, the authors added.
“This bidirectional relationship underscores the importance of integrated medical and dental screening and management strategies to improve patient outcomes for both conditions,” Chang and colleagues concluded.
