Current statement of the FDA about dental amalgam and implanted metal devices

Current statement of the FDA about dental amalgam and implanted metal devices: „Implanted metal devices, dental amalgam to go under FDA’s microscope.“


Figure 1: U.S. Food & Drug Administration (1)

The U.S. Food and Drug Administration (FDA) wants dental amalgam and implanted metal devices (like titanium implants) to go under FDA’s microscope. On November 13-14 2019, a public meeting of the Immunology Devices Panel of the Medical Devices Advisory Committee will take place, which is expected eagerly (1).

But what is the purpose of the FDA to deal with this issue?

Such a meeting is overdue, hopefully it will provide the necessary steps and bans to protect the population from the health risks associated with the use of metals in the oral cavity. The risks are well-known and scientifically proven:

Dental amalgam

50% of dental amalgam is elemental mercury. Mercury is one of the most toxic, non-radioactive elements on our planet (2,3). According to the European mercury regulation, dental facilities should be equipped with amalgam separators to protect waste water and our environment from further pollution. After being removed, amalgam must be disposed of as highly toxic hazardous waste, which is a financial burden for the dental office. Nevertheless, in Germany the percentage of dental amalgam fillings still is around 30% (4). Each year, approximately 15 tons of mercury are required for dental amalgam fillings (3,5). 

From 1 July 2018, dental amalgam should not be used in the treatment of children under 15 years of age and in pregnant or breastfeeding women (5). In Norway, Sweden, Denmark, Russia and Japan, amalgam is already completely banned for its use. 

In 1992, Dr. Ulrich Volz wrote his doctoral thesis on the risks of amalgam (Title: “Qualitative investigations of amalgam invasion into the dental pulp”). Small amalgam fillings in wisdom teeth were used to investigate the release of amalgam in the tissue. He demonstrated that amalgam was found directly in the pulp and in the cell nuclei of the tissue after just 24 hours (6).

Many studies proved already the negative health effects of mercury. It is associated with neurodegenerative diseases such as Parkinson’s disease and multiple sclerosis (7–9). Autism (especially in children) is related to a high mercury level (10,11). An increasing number of maternal dental amalgam fillings correlates with increased fetal exposure in utero. Human placenta does not represent a real barrier to the transport of mercury (12–14). Due to its neuro- and immunotoxic potential, mercury is considered by the WHO as one of the top ten chemicals of major public health concern (15). The half-life of inorganic mercury in the human brain is estimated to be several years to decades (3). 

The following x-ray of a sheep demonstrates the accumulation of mercury in the entire organism only 24 hours after placing amalgam fillings. The most affected organs are the kidneys, liver and stomach:


Figure 2: How mercury get’s out of amalgam and into your body (16)

Even after 50 years of wearing, mercury vapor can be released from amalgam fillings:

Titanium implants

Besides dental amalgam as an intraoral interference field, implanted metal devices like titanium dental implants may have negative health effects on the entire organism. In September 2019, the traditional dental society “New Group” dedicated an entire congress to ceramic implantology. Prof. Terheyden, president of the German Association of Oral Implantology (DGI) from 2010-2013, stated that titanium is a highly reactive material and emphasized growing evidence for the biocorrosion of this metal. At the ESCI Congress (European Society of Ceramic Implantology) in Zurich this year, the multiple negative effects of titanium implants on the organism were discussed. Due to corrosion of the titanium surface, titanium particles will be released which infiltrate the surrounding tissue. The particles may be associated with the development of periimplantitis and implant loss (18–21). 

The following figure shows the x-ray and the intraoral picture of periimplantitis. Bone loss and exposed implant threads are visible: 


Figure 4: Hessam N, Jorgensen M. Dental Implant Maintenance (22)

Factors that contribute to corrosion are of mechanical, chemical and electrolytic origin (23). Particle release occurs due to mechanical friction during insertion of the implant and/or micromovements of the implant while chewing (19,24). Macrophages react to contact with titanium oxide particles causing an immune response by releasing pro-inflammatory cytokines like tumor necrosis factor-α (TNF-α, an inflammatory messenger) and interleukin-1β (IL-1β); osteoclasts are activated and bone and tissue resorption can occur (25–28):

Figure 5: left: Hallab NJ, Jacobs JJ: Biologic effects of implant debris (28) and right: Olmedo et al: Oral mucosa tissue response to titanium cover screws: lymphocytes associated with a metal particle (arrow) (29)

The released particles are a constant stimulus for the body’s immune system, producing a chronic immunological reaction. Besides local effects, the released pro-inflammatory cytokines have systemic impacts on many tissues such as muscles, endothelium and the nervous system (see figure 6) (25,30). Thus, systemic diseases such as rheumatoid arthritis, multiple sclerosis, tumors, breast carcinomas and cardiovascular diseases can be initiated by titanium implants due to an overexpression of TNF-α (31).


Figure 6: Dr. Elisabeth Jakobi-Gresser: Pathogenesis of periimplantitis (32) 

Furthermore, titanium oxide nanoparticles have cytotoxic and genotoxic potential and cause oxidative stress (33). Studies have been published that associate neoplasms such as osteosarcoma, plasmocytoma or breast metastasis  with titanium dental implants (34–36). Metals such as titanium can cause hypersensitivity and allergic reactions (37–39). Harloff et al. found traceable amounts of palladium, nickel and chromium in implant material samples. These elements also can be associated with allergic reactions. Nickel, which is one of the main allergens and causes sensitization in about 12% of the population is present in all titanium dental implants. Due to its low content, manufacturers do not have to label it, but even these small amounts may be sufficient to trigger allergic reactions (40):


Figure 7: Harloff et al.: Titanium allergy or not? “Impurity“ of titanium implant materials (40)

In summary, amalgam and other metals such as titanium should not be incorporated into the human body. A safe protocol to remove them is necessary. In particular dental amalgam fillings should be removed under high protection measures to avoid further exposure to mercury vapors. The biocompatible zirconium dioxide (used in the Swiss Biohealth Clinic) instead of titanium for dental implants offers a biological, non-reactive alternative and protects patients’ health. Another important aspect is to avoid food or cosmetics which contain metals such as titanium dioxide or heavy metals (see titanium dioxide particles in our food at 

The meeting of the FDA’ s Committee on 13-14 November 2019 will hopefully consider these serious problems and risks and draw the necessary conclusions. Under following link, it will be possible to attend the meeting live and online:

Deep Sleep = Anti Aging?

My personal and professional involvement in biological medicine and dentistry for over 30 years has shown me that there are a few key factors that have an oversized effect on our health and performance according to the Pareto principle (80/20 principle). Biological dentistry shows an outstanding special position here, as the dead teeth and toxic materials in the oral cavity are responsible for about 60 to 80% of all chronic diseases according to estimates of opinion leaders and our own observations.

Mobile communication and healing of implants

Mobile radio reduces the healing of dental implants by disturbing the bone metabolism and increasing the tendency for inflammation. After Brussels, Geneva now also rejects the introduction of 5G technology.

cell phone radiation

This exciting study was found by Max Riemann, an SDS user and member of our SWISS BIOHEALTH EDUCATION training center and communication platform. The Pubmed study shows that titanium implants exposed to mobile phones in the healing phase are less healthy, have less bone contact and are more susceptible to inflammation:  Read More Mobile communication and healing of implants

In this blog post I will report on the further regeneration after my own operation, which I have continued in the completely radio-free nature of Brazil. This shows how important it is – especially after surgery – to avoid EMF as much as possible. You can also achieve this at home, and I will give you all the information about it! In addition, I will show the central importance of the movement in nature and explain the benefit especially for chronically ill people. If you have not read the first part, feel free to do so here.

Root Cause – the root of all evil?

The film “Root Cause” reports on the dangers of root-treated teeth and ischemic osteonecrosis during a ten-year personal search for the cause of the chronic fatigue, the filmmaker and producer and actor Ben Purser suffers from. Rarely before has this topic generated so much audience attention as through this movie and let the waves blow up that much on both sides, the supporters of the theory as well as the opponents.
You can currently find the movie on Amazon Prime, iTunes and Vimeo.

Basically, we think it’s good that the topic Root Cause, which affects hundreds of millions of people around the world (in the US alone, around 25 million new root-canal treatments are being treated each year) is becoming a public focus and hopefully will lead to Dentists, immunologists, oncologists, cardiologists, orthopedists and internists coming together and dealing more intensively with this issue in the interest of the health of patients or humanity according to the official rules of medicine and science!

Biological Dentistry 2.0 – my own experiences

Biological Dentistry 2.0 – Protocol about my own experiences regarding my ALLINONE-Operation and my My BIOHEALTH Week
by Dr. Karl Ulrich Volz

The moment I had waited for, for many years, maybe even decades:
On the 14th and 15th of February, I spent a total of 19 hours on the treatment chair in my SWISS BIOHEALTH CLINIC. It was the first time that my extremely competent team, built up over many years,

  1. a) had my 100% confidence
  2. b) the products, which I needed myself, were developed and
  3. c) I knew that I would not suffer in spite of the major surgery considering the My BIOHEALTH Week!

Not only that this experience of BIOLOGICAL DENTISTRY 2.0 was a magnificent experience and I feel even better since then – I have gained many valuable insights for my patients (“you do not learn how to swim in a bathtub …!”) and therefore, in the future, will be able to feel more compassion and empathy as a doctor for my patients!
