Various studies though the years have shown that marijuana use could affect hormone levels in varying degrees in both males and females. The most significant of which being that it causes a decrease in male fertility. Studies of smoking marijuana have also demonstrated an increase in lung pathology due to the damaging effects of the cell linings in the large airways.
In terms of how it affects the individual’s mouth we previously knew of marijuana causing a decrease in saliva as well as staining of the teeth a brownish tint. In the January 9th, 2025 issue of the Journal of the American Dental Association, it looked at the results of over 5600 individuals who self-reported that they used marijuana or hashish at least once a month and researched their dental history a little more closely.
It appears that these individuals, whose ages ranged from 18-59 years of age, had a 17% higher rate of untreated tooth decay, 55% higher average of untreated root decay and a 41% higher incidence of tooth loss versus a controlled study group. These numbers suggest that marijuana use may be a significant factor in one’s dental health over time.
Further studies need to be done to determine the frequencies, quantities and forms of cannabis use and their impact on dental pathology but we do know it can affect the dental health of patients in some capacity. Dentists and patients alike should be aware of the possible dental issues of regular marijuana use based on this study.
