No link between dental health and high blood pressure: study

US researchers assessed periodontal disease, tooth loss and blood pressure among 30,000 male health professionals aged 45–75 years who were tracked over 20 years.

There were 10,800 incident cases of hypertension over the period.

While recent scientific evidence suggested a possible connection between periodontal disease and systemic inflammation, no such link was found in this study.

Even men with severe periodontal bone loss showed no significant increase in risk for hypertension, they found.

Several longitudinal studies have demonstrated a relationship between circulating levels of inflammatory markers such as C-reactive protein and incidence of hypertension.
