Implant Toxicity, Both Sides: Breast Implant Illness, Mercury Fillings, Titanium vs. Zirconia, and Metal Hips

Can the materials we put in our bodies make us sick? From breast implant illness to mercury fillings, some concerns started in holistic circles and are now recognized by the FDA. Here's the case for and against, and how to make an informed choice.

A root-cause approach to health asks what the body is exposed to every day, and for many people, that includes materials implanted in the body: breast implants, dental fillings, dental implants, and joint replacements. Some concerns about these materials started in holistic communities and were dismissed for years, and some are now formally recognized by the FDA. Others remain debated.

As with the rest of our controversial therapies series, here's both sides.

Breast Implant Illness (BII)

The concern

Many women with breast implants report a range of symptoms they believe are linked to their implants: fatigue, brain fog, joint and muscle pain, hair loss, rashes, anxiety, and autoimmune-like symptoms. This collection of symptoms is known as breast implant illness. Large online communities formed as women shared their experiences, and many report significant improvement after having their implants removed (explant surgery), often with the surrounding scar capsule.

What's recognized

• The FDA takes the reports seriously. In 2021, the FDA required a boxed warning and a patient decision checklist for breast implants, noting that some patients report systemic symptoms, including those associated with BII.
• A rare cancer is confirmed. Breast implant associated anaplastic large cell lymphoma (BIA-ALCL), a cancer of the immune system, is linked mainly to textured implants. A widely used textured implant was recalled worldwide in 2019. The FDA has also reported cases of other cancers in the scar tissue around implants.
• Implants aren't lifetime devices. Rupture, capsular contracture, and other complications become more likely over time.

The debate

• Research is still catching up. Studies are working to understand why some women develop symptoms, which vary widely from woman to woman. Studies of explant surgery have reported symptom improvement in many patients, but most are small and without comparison groups.
• Some researchers see a real immune reaction to silicone or the implant shell in susceptible people, while others are more cautious.

If you have implants

Know which type and texture you have, keep up with recommended imaging, report new symptoms to your doctor, and if you're considering removal, consult a board-certified plastic surgeon experienced in explant and capsulectomy.

Mercury (Amalgam) Fillings

The concern

"Silver" fillings are about 50 percent mercury, bound with other metals. Holistic and biological dentists, including organizations like the International Academy of Oral Medicine and Toxicology (IAOMT), have long argued that these fillings release small amounts of mercury vapor, especially when chewing, grinding, or drinking hot liquids, and that this adds to the body's toxic load over time.

What's recognized

• The FDA updated its guidance in 2020, recommending that dentists avoid placing new amalgam fillings, when appropriate, in higher-risk people: pregnant and nursing women, women planning pregnancy, children under 6, people with neurological disease or impaired kidney function, and those with a known sensitivity to mercury.
• Amalgam does release small amounts of mercury vapor, especially during placement and removal.

The debate

• Mainstream dental organizations maintain that for most people, the amount of mercury released from intact fillings is below levels shown to cause harm.
• The FDA does not recommend removing intact fillings that are in good condition, since removal itself releases a burst of mercury vapor.

If you're considering removal

Look for a dentist trained in safe removal, such as the IAOMT's SMART protocol, which uses rubber dams, high-volume suction, air filtration, and protective equipment to reduce exposure during removal. Composite (tooth-colored) and ceramic materials are common replacements.

Titanium vs. Zirconia Dental Implants

The concern

Most dental implants are titanium, which has decades of success. Some holistic dentists prefer metal-free zirconia (ceramic) implants, citing concerns about titanium allergy or sensitivity, tiny titanium particles released into surrounding tissue over time, and the principle of avoiding metal in the body.

The evidence

• True titanium allergy appears to be rare, but researchers are studying titanium particles found in tissue around implants and their possible role in inflammation and implant failure (peri-implantitis).
• Zirconia implants are metal-free, look tooth-colored, and tend to attract less plaque, but they have less long-term research than titanium, and some designs can be more prone to fracture.

If you need an implant

Ask about both materials, the dentist's experience with each, and the long-term success data. For some people, particularly those with metal sensitivities, zirconia is a reasonable choice.

Metal-on-Metal Hip Implants

This one isn't controversial, but it's worth knowing. Some hip replacements made with metal-on-metal components (cobalt and chromium rubbing together) were found to release metal ions into the blood. In some patients this caused local tissue damage and, rarely, systemic problems like heart, nerve, or thyroid issues. The FDA issued safety communications, several devices were recalled, and patients with these implants are advised to have regular follow-up, including blood metal levels when recommended. If you have a metal-on-metal hip, ask your orthopedic surgeon about monitoring.

A Root-Cause Takeaway

For anyone working through unexplained, chronic symptoms, it's reasonable to include implanted materials in the conversation with your providers, alongside diet, gut health, infections, stress, and environmental exposures. The goal isn't fear. It's making sure nothing important is overlooked.

Where MK Wellness Fits

We don't evaluate or remove implants. But our Detox & Immune Support guide covers how the body processes toxins and what supports it, and many clients use therapies like infrared sauna and lymphatic therapy as part of their overall wellness routine, including during recovery after surgery, with their surgeon's approval.

MK Wellness services are non-medical and not intended to diagnose, treat, cure, or prevent any condition. This article is general education presenting multiple perspectives, not medical or dental advice. Talk with your physician, surgeon, or dentist about your specific implants, fillings, or symptoms before making any decisions.
