Poor dental health has previously been linked to depression. Now researchers have found that your oral health could also be a risk factor for this mood disorder that causes a persistent feeling of sadness and loss of interest.
Previous studies had examined the idea that poor dental health was caused by depression. However, this study found that people with more dental conditions also had depression that was more severe. Specifically, the data indicated that those people with multiple dental conditions had a significantly higher prevalence of depression than individuals without an oral health condition.
This study adds to theories regarding the effect of oral health and bacteria on mental health. Researchers involved in the study note that if poor oral health is a risk factor for depression, it has implications for both the prevention and management of depression.
The Australian-based researchers found the link while studying the data of more than 10,000 adults and children in the United States.
The study was published in General Hospital Psychiatry.
