Topic: Fact of the day: dental amalgam fillings consist of 50% mercury
Anonymous A started this discussion 2 years ago#110,752
While many organisations believe this is safe, this view is not uncontroversial, with critics stating that the health consequences and potential neurotoxic effects of chronic low-level exposures to mercury remain understudied.
Aside from the potential direct health consequences, the World Health Organization estimates that 5% of all waste water mercury contamination is from dental fillings.
Sweden and Norway have now banned their use in dentistry.
It would've been great if I had been informed about this before I got multiple of these fillings. But in this world, you really can't count on anyone to have your interest at heart, especially anyone who's part of a modern day guild.

Listen here you little shit.
Dental amalgam is a mixture of metals, consisting of liquid (elemental) mercury and a powdered alloy composed of silver, tin, and copper. Approximately half (50%) of dental amalgam is elemental mercury by weight. The chemical properties of elemental mercury allow it to react with and bind together the silver/copper/tin alloy particles to form an amalgam.
Dental amalgam is a mixture of 50% elemental mercury with a metallic alloy which mainly contains silver and tin. The liquid mercury is mixed with the alloy powder in a 1 to 1 weight ratio.
Kwik en kwikdampen vormen bronnen van gevaar voor de gezondheid in elke tandartspraktijk. Met een aandeel van 50 procent is kwik het hoofdbestanddeel van tandheelkundig amalgaam.

Resin is made of bisphenol A (aka BPA). Frankly, I'd rather have mercury amalgam than that shit in my mouth any day of the week.
If you told me these facts a few days ago before I found this out, I'd probably think you were joking. Because I had never realised how much a joke modern dentistry is.

> The health effects of BPA have been the subject of prolonged public and scientific debate,[12][13][14] with PubMed listing more than 17,000 scientific papers as of 2023.[73] Concern is mostly related to its estrogen-like activity, although it can interact with other receptor systems as an endocrine-disrupting chemical.[74] These interactions are all very weak, but exposure to BPA is effectively lifelong, leading to concern over possible cumulative effects. Studying this sort of long‑term, low‑dose interaction is difficult, and although there have been numerous studies, there are considerable discrepancies in their conclusions regarding the nature of the effects observed as well as the levels at which they occur.[12] A common criticism is that industry-sponsored trials tend to show BPA as being safer than studies performed by academic or government laboratories,[14][75] although this has also been explained in terms of industry studies being better designed.[13][76]

> BPA has been found to interact with a diverse range of hormone receptors, in both humans and animals.[74] It binds to both of the nuclear estrogen receptors (ERs), ERα and ERβ. BPA can both mimic the action of estrogen and antagonise estrogen, indicating that it is a selective estrogen receptor modulator (SERM) or partial agonist of the ER.
