A new study has revealed that regular use of cannabis can lead to extensive tooth loss due to the fact that the habit leaves the person vulnerable to gum disease, which is a leading cause of tooth loss. The research involved over a thousand people who smoked the drug regularly for up to twenty years.
Periodontal disease (gum disease) is a very common condition, but marijuana can exacerbate the condition and lead to tooth loss in the early thirties, or certainly by middle age, with regular use.
The study was carried out by Dr Madeleine Meier, of Arizona State University, and involved 1037 people born in New Zealand between 1972 and 1973 and followed them until they reached 38. Lab tests checked gum health, as well as lung function, systemic inflammation and metabolic health. The results showed that regular use of the drug can cause devastating gum disease at a young age, and it has been suggested that this is because regular users neglect their dental health, not bothering to brush or floss to prevent the disease from developing. Previous research has also supported this theory and it has been found to significantly raise risk of gum disease among the younger generation.
