World Arthritis day
The burden of arthritis pain is only increasing and according to Lancet, the number of people living with osteoarthritis alone could be around 1 billion by 2050.
Let us talk about an important yet often neglected or underrated aspect of Arthritis.
Arthritis Oral health Axis!
Joint pathology and oral inflammation have a shared molecular biological pathway which has been studied and researched thoroughly.
A pathogen which is predominant in periodontal ( gum issues) diseases has been isolated from the synovial fluid of patients with arthritis. Furthermore, P. gingivalis produces enzymes that alter host proteins, triggering a hyperactive autoantibody response. Through molecular mimicry, this aberrant immune cascade ultimately targets and degrades healthy cartilage and joint structures (Persson, 2012).
Encouragingly, Studies have shown that there is a significant decrease in the level of CRP and circulating anti pathogen antibodies following aggressive periodontal ( gum) therapy.
However the connection is bi-directional!
Oral issues that can be triggered due to arthritis are usually categorised as -
Medication related complications such as dry mouth, oral ulcers,gum diseases or oral thrush.
Jaw pain, clicking or popping noises, limited mouth opening and muscle spasms due to arthritis.
Poor or decreased oral hygiene due to decrease in dexterity.
The studies, the research and experience clearly establishes the importance of interdisciplinary and multidisciplinary approach needed in providing a holistic and long term care to patients. The compelling link between periodontal disease and systemic joint destruction serves as a powerful reminder: we cannot treat the joints while ignoring the mouth.
Healing demands an integrated, multidisciplinary approach that bridges the gap between medicine and dentistry. By recognizing oral health as a vital component of arthritis management, we do not merely alleviate symptoms—we restore dignity, protect systemic well-being, and meaningfully transform our patients' quality of life.
