Mental Illness Leads To Worse Oral Health
According to a recent meta-analysis in the British Journal of Psychiatry, those who have mental illnesses are 3.4 times more likely to have lost their teeth and 6.2 times more likely to have decayed, filled or missing teeth. The journal doesn’t argue that this is a result of mental illness directly, but indirectly. An interesting article in the University of Queensland News provides a number of possible explanations, from homelessness to paranoia about going to the dentist to lack of funds.

The recommendations of the studies authors, that those who have mental health illnesses get proper checkups for oral health as a part of their care, is a good start. Certainly it would catch some of the worst problems before they get out of hand. However, so long as dental care is treated differently from medical care, this problem will likely be fairly intractable.
