There are many aggravating factors for a migraine, ranging from dehydration and exhaustion to hormonal changes and stress. But new research has found another connection: poor oral health.
A year-long study, conducted in New Zealand by the University of Sydney, found that poor oral health correlates with higher reported migraines among women. The proposed explanation is that pathogenic bacteria in the oral cavity spreads around the body and increases the risk of migraines, as well as abdominal pain and fibromyalgia.
The prevalence of migraines is 5-25% in women; in men it is 2-10%. Due to this high prevalence, the more we know and understand about what can cause migraines and other pain conditions, the better. The findings of the study have helped – it investigated the oral microbiota in the participants and found four pathogenic species that were associated with bodily pain. These are:
It has long been known that oral pathogens are implicated in the aetiology of chronic conditions because of the gastrointestinal tract, but, until now, the role they play in pain and sensitisation disorders has not been fully explored. The results of the study have therefore laid a sturdy framework for future research.
As the lead investigator of the project, Joanna Harnett identifies the trailblazing nature of the research:
“This is the first study to investigate oral health, oral microbiota and pain commonly experienced in women with fibromyalgia, with our study showing a clear and significant association between poor oral health and pain.”
These thoughts were also echoed by Sharon Erdich, PhD candidate in the Faculty of Medicine and Health:
“Our findings are important to fibromyalgia which, despite being a common rheumatological condition, is often underrecognised.”
As the frequency and severity of migraines are greater among women with poor oral health, this emphasises how the mouth is often at the centre of a holistic approach to health. By taking care of the teeth, we can help take care of the body.
Since you’re here, why not read about how the bacteria in your mouth is associated with mental health?
