🦴 Large Joint Pain: A Commonly Overlooked Toxic Cause

Pain in the large joints—such as the knees, hips, and elbows—is commonly attributed to conditions like osteoarthritis or autoimmune disease. However, in some individuals, a toxic exposure–related condition known as skeletal fluorosis may be an overlooked contributor.

Skeletal fluorosis results from long-term accumulation of fluoride in bone tissue. Because its symptoms can closely resemble arthritis, lupus, or other inflammatory joint conditions, it is frequently misdiagnosed. This is problematic, as addressing fluoride exposure may significantly improve symptoms, whereas conventional autoimmune diagnoses often focus on symptom management rather than underlying causes.

🦷 Dental Materials as a Source of Fluoride Exposure

Modern white (composite) dental fillings and many dental cements used for crowns contain plastic polymers and fluoride compounds. Over time, small amounts of these substances may leach from dental materials.

Because teeth are highly vascularised, chronic exposure through dental materials may contribute to systemic fluoride absorption in susceptible individuals. In the long term, this fluoride burden can accumulate in bones and joints.

🦵 Why Large Joints Are Often Affected

Skeletal fluorosis tends to affect weight-bearing and large joints, particularly the knees. Progressive stiffness, pain, and reduced mobility may eventually lead patients to undergo joint replacement surgery.

While knee replacement surgery can relieve pain, it involves implanting metal alloys and plastic components. In some individuals, long-term exposure to implanted materials may contribute to additional biological stress, particularly where toxic burden already exists.

⚠️ Heavy Metals, Immune Dysregulation & Chronic Pain

There is increasing scientific interest in the role of heavy metals and environmental toxins in immune dysregulation and chronic inflammatory conditions.

In certain individuals, reducing ongoing toxic exposure and supporting detoxification pathways may lead to meaningful symptom improvement, even where conditions were previously labelled as autoimmune.

🧪 Recommendations

1. Identify Toxic Exposure

Establish which toxins may be present in the body before attempting treatment.

• Hair mineral analysis for heavy metals and fluoride
  (Currently not available in South Africa)

2. Assess Immune Sensitivity

• Based on screening results, consider MELISA testing for immune reactivity to specific metals

3. Reduce Ongoing Exposure

• If fluoride burden is identified, discuss replacement of fluoride-containing dental materials with biocompatible alternatives with a suitably trained dental professional

🔑 Key Takeaway

Not all joint pain is mechanical or autoimmune in origin.
In some cases, it may be toxic, cumulative, and potentially reversible once the underlying exposure is identified and addressed.
