New research unveils a surprising connection between oral health and fibromyalgia symptoms in women, offering hope for better pain management through improved dental care.
At a Glance
- Women with poor oral health are 60% more likely to experience moderate to severe body pain and 49% more likely to suffer from migraines
- Fibromyalgia affects women three times more often than men and is frequently associated with oral health issues including dry mouth and temporomandibular joint disorders
- Specific oral bacteria from the Dialister, Fusobacterium, Parvimonas, and Solobacterium genera have been linked to pain conditions
- Maintaining good oral hygiene may help reduce fibromyalgia symptoms and improve overall quality of life
The Fibromyalgia-Oral Health Connection
Fibromyalgia, a chronic condition characterized by widespread pain, fatigue, and sleep disturbances, affects approximately 4% of the global population with a female-to-male ratio of about 3:1. Recent groundbreaking research from the University of Sydney has established a clear link between poor oral health and increased pain symptoms in women, particularly those with fibromyalgia. The study, published in Frontiers in Pain Research, is the first to identify specific oral microbes correlated with certain pain conditions, potentially offering new avenues for treatment and symptom management.
Associate Professor Joanna Harnett, lead researcher on the study, states: "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." The findings revealed that women with poor oral health were 60% more likely to experience moderate to severe body pain and almost 50% more likely to suffer from migraines compared to those with good oral health.

Common Oral Health Issues in Fibromyalgia Patients
Fibromyalgia patients frequently experience a range of oral health complications that can exacerbate their overall symptoms. Xerostomia, or dry mouth, is particularly common and can lead to serious dental problems. When saliva production decreases, patients may develop burning mouth syndrome, difficulty in chewing and swallowing, increased dental cavities, gum infections, and even tooth loss. These conditions not only cause additional pain but can also impact nutritional intake and overall quality of life.
Temporomandibular joint disorders (TMD) represent another significant oral health issue for fibromyalgia patients. TMD can cause teeth grinding (bruxism), jaw pain, and chronic headaches, creating a vicious cycle of increased pain sensitivity. Research has consistently shown a correlation between fibromyalgia, depression, and TMJ disorders, with some studies suggesting that central nervous system alterations seen in fibromyalgia patients may contribute to TMD development and persistence.
The Migraine Connection
The relationship between fibromyalgia, oral health, and migraines represents a complex but increasingly understood phenomenon. A 2019 study found that migraine episodes are twice as likely in people with fibromyalgia, and approximately 30% of people with migraine symptoms also have fibromyalgia. Both conditions involve atypical levels of neurotransmitters like serotonin and norepinephrine, and they frequently co-occur with other conditions such as depression and anxiety.
The University of Sydney research specifically identified oral bacteria that may play a role in this relationship. Bacteria from the Dialister, Fusobacterium, Parvimonas, and Solobacterium genera were linked to increased pain sensitivity and migraine frequency. This discovery suggests that oral infections and inflammation may trigger or worsen both fibromyalgia symptoms and migraine attacks, particularly in women who are disproportionately affected by these conditions.
Practical Recommendations for Better Management
For women living with fibromyalgia, maintaining good oral health may be a crucial yet often overlooked aspect of symptom management. The Australian Dental Association recommends regular oral hygiene appointments, dental health checks, and twice-daily teeth brushing and flossing. These simple practices could potentially reduce pain severity and frequency of migraine attacks. For dry mouth, treatment options include saliva substitutes, specialized dry mouth products, and dental products containing fluoride or calcium to prevent tooth decay.
Healthcare providers should consider adopting a multidisciplinary approach to fibromyalgia treatment that includes dental professionals. Patients may benefit from modified dental treatment protocols that account for their increased pain sensitivity. Short, morning appointments with breaks, mild sedation options, and careful pain management during procedures can make dental visits more comfortable for fibromyalgia patients. By addressing oral health as part of a comprehensive treatment plan, healthcare providers may help improve both symptom management and quality of life for women living with this challenging condition.
