Potential Health Risks related

to Dental Fillings

Dental resin composite that are white or tooth-colored materials have been considered as possible substitutes to mercury-containing silver amalgam filling. Despite the fact that dental resin composites have improved their physico-chemical properties, the concern for its intrinsic toxicity remains high. Some components of restorative composite resins are released in the oral environment initially during polymerization reaction and later due to degradation of the material. In vitro and in vivo studies have clearly identified that these components of restorative composite resins are toxic.

Routes of absorption

The possible routes of systemic intake of chemical substances released from resin based composites can be through (i) oral mucosa directly, (ii) diffusion to pulp via dentinal tubules,[2] (iii) absorption of volatile components in lungs[6,7] and (iv) ingestion of released components in the gastrointestinal tract.[8]

BPA is an endocrine disrupter, which means it mimics or interferes with your body's hormones and "disrupts" your endocrine system. The glands of your endocrine system and the hormones they release influence almost every cell, organ, and function of your body.

It is instrumental in regulating mood, growth and development, tissue function, metabolism, as well as sexual function and reproductive processes. BPA has been linked to a number of health concerns, particularly in pregnant women, fetuses and young children, but also in adults, including:

Serious Health Risks Linked to BPA, Even at Low-Level Exposure

Structural damage to your brain     Changes in gender-specific behavior     Abnormal sexual behavior      Hyperactivity     Increased aggressiveness

​impaired learning        Early puberty        Stimulation of mammary gland development         Disrupted reproductive cyclesOvarian dysfunction 

infertility         Increased fat formation and risk of obesity    Stimulation of prostate cancer cells        Altered immune function             

Increased prostate size and decreased sperm production



Dental amalgam is a liquid mercury and metal alloy mixture used to fill cavities caused by tooth decay.[1] Low-copper amalgam commonly consists of mercury (50%), silver (~22–32%), tin (~14%), copper (~8%) and other trace metals.

Dental amalgams were first documented in a Tang Dynasty medical text written by Su Kung in 659, and appeared in Germany in 1528. In the 1800s, amalgam became the dental restorative material of choice due to its low cost, ease of application, strength, and durability.

However, traditional amalgams contain 50% mercury which is considered to be a Neurotoxin.

Neurotoxins are toxins that are poisonous or destructive to nerve tissue. Neurotoxins are an extensive class of exogenous chemical neurological insults that can adversely affect function in both developing and mature nervous tissue.

Silverfil is the only amalgam alternative that is 100% non-toxic and does not contain any elemental or free mercury.
