Study suggests poor oral health could lessen survival from head and neck cancer

An international study has revealed strong associations between oral health and survival among people diagnosed with head and neck cancer. Specifically, better oral health, as evidenced by the number of natural teeth and dental visits prior to the time of diagnosis, was associated with increased survival. Importantly, those who had more frequent dental visits were more likely to have their cancer diagnosed at an earlier, and less deadly, stage of the disease than those who had few or no dental visits.
