Higher testosterone levels are linked with an increased risk of gum problems, says a study published in the June issue of the Journal of Periodontology.
The study used data from a national survey, and included 755 men aged 30 and older.
Men with the highest testosterone levels had about double the risk of gum disease, compared with men who had lower levels. They also tended to have more severe gum disease.
Sex hormones such as testosterone are linked to inflammation, and they also affect bone. A 2009 study did not find that testosterone levels were linked with gum disease in men; however, this study only looked at men aged 65 and older.
