Oils and amalgam fillings

Robert - 02 Jun 2008 13:38 GMT I read of some new technique that some people are using of swishing their teeth with some kind of vegetable oil every day for 15-20 minutes. They say it improves their gums. Sounds harmless enough, even if not effective.
However, some also said that this technique can loosen amalgam fillings because the oil leeches the mercury out.
Is it possible that long-term exposure of teeth to oils can actually loosen silver fillings?!

It sounds nutty to me too. But actually I phrased the question wrong. What I was really asking is are there foods or liquids that are known or suspected to loosen amalgam fillings? Resin fillings? (Not including chewing on hard candy or ice cubes :)

Luckily he did not swallow.
Nevertheless the enamel was chalky and highly friable. We made some custom fluoride trays for him and provided 0.4% SnF gel. The enamel remineralized and to this day there are no sequelae. Eight years and counting.
Yep, have treated the anorexia/bulimia patient. Here's my take...
Clinically, prominent acidic erosion of the lingual surfaces of the anterior region is very common. That finding in conjunction with other recognizable symptoms, may the first clue to the dental practitioner of this disorder.
Occlusal surface acidic erosion is likely to be indicative of longer term sequelae of the pathologic process and palatal cusp erosion since enamel is thicker in the upper molars, may be considered by some as pathognomonic.
In extreme cases mandibular lingual cusp erosion will also be present. Due to *protection* by the tongue during 'purging' the lower molars are somewhat 'preserved' for a longer period of time, but are not immune to acidic damage.
We can help mediate the damage to the teeth, but the underlying factors causing the behavior must be addressed. Treatment of the psychological nature is well beyond the scope of dental practice. However we must at least inform the patient of our clinical findings and the diagnosis that is suggested.
Informing a patient of our findings, and especially in the presence of a family member or caretaker can sometimes be enough to effect seeking treatment for the underlying causes of this disorder.

Rob, Keep in mind that dentists do not have a remote clue about the chemistry of amalgam and mercury, it's like asking a blind man what time it is.. in fact even hot coffee has been shown to greatly elevate Hg release from amalgam for hours, but don't worry about any liquid loosening the Hg. It comes off the filling all by itself, as a vapor! (and then will dissolve in any liquid you swoosh around).

For example, here are a few studies that suggest that amalgam fillings have better longevity than composites. If the mercury dissipated like that wouldn't you expect a higher failure rate?

It's also well known that Amalgam continously emits a vapor of hg-it has a vapor pressure. you might want to check out Boyd Haley's website or the large German study, the tubigen study. In fact their are tons of studies.

Well, let me ask you this. The Sun is basically a nuclear reactor. hydrogen is constantly converted to sunlight. Does that mean that if the Sun does lose hydrogen, in a few years it's lights out? Actually the amount of Hg released from a typical filling, say as a vapor is a fraction of the total hg content of the filling. I think its in the neighborhood of 3-100 ug per day and a typical filling has about a gram of Hg. You can do the math. The reason that fillings can lose half their Hg over many years , is because if you look at microscopic photos of the grains in a filling you will see that the other metallic bonds can retain their structure and strength, even in areas which lose Hg. I.e the Hg level is not critical to maintaining the structural integrity of the filling.
As for whether I would expect a higher failure rate, even the ADA recommends they be replaced every 10 years or so, but I wouldn't expect a filling which has lost 10-50% of it's Hg necessarily to fail. In fact fillings expand, even while they lose Hg! A filling that has lost a lot of Hg might have a greater change of cracking, I suppose, but they are made of metal and metal is pretty strong .

> As for the claims about amalgam fillings I only see unsubstantiated > pronouncements on holistic web sites. That's because you only get your information from the ADA! Go to the FDA, there have been thousands of adverse reactions reports (which they never investigate). In fact they held an FDA hearing two years ago. The expert committe did not concur with ADA claims of safety. A huge study was done in Germany documenting cases of large release of Hg from fillings. Go to Boyd Haleys' website (he is former U of kentucky chemistry head). He's got tons of scientific references. If you think that fillings don't release significant amounts of Hg , id really like to make a substantial wager. Of course the fact that due to filling contruction, galvanic action etc some people might get larger doses is a separate question from what the Hg dose is from an average filling. That is a question of scientific certitude not a "holistic claim". It's about 80% of your average elemental Hg exposure, What effect that would have on an individual is obviously not an easy question to quantify.

Heat will naturally increase release of mercury vapor from amalgams. Of course, the duration of the heat is generally pretty small. I have never seen any detectable increase in oxidation of amalgams in heavy coffee drinkers. I've never seen a study comparing the stability of amalgam in exposure to certain foods. My guess is that the best compounds for sequestering mercury from amalgam would be sulfur-containing foods, such as egg yolks.

Most absorption of mercury from amalgams is almost certainly through the lungs. Most absorption from seafood is through the gut, in the form of methylmercury.

It's [quoted text clipped - 10 lines] > to me is, do we ingest more mercury from the seafood we eat than we do from > the amalgam fillings in our mouths? Notice this study was published by the NIDCR that is staffed by Dentists, who are members of the ADA. These military studies have been discussed on this group before. This particular study does not actually measure the release of Hg from a filling as a function of coffe, nor does it have the statistical power , or attempt to draw epidemologicl conclusions. What it does do is look, far from the source of the Hg release, in the blood stream, to "see" what the Hg levels are. As has been discussed before in this group, apparently with no comprehension by the dentists. you CANNOT determine Hg exposure by measuring the level in the blood. The measurement is useless. Lead yes, Hg no. Since this study did not, actually a) determine how much Hg was absorbed in the nervous system, through autopsy or challenge test, b) measure the hg directly as it came of the filling,but used methods shown by newer studies to be inaccurate its simply garbage.
For instance, those with the most Hg exposure actually have decreased ability to excrete it, so their blood level and urine levels are less. Hg is absorbed directly into the organs and nervous systems, and does not stay long in the blood.
There are many other problems with these types of garbage studies used by the FDA and NIDCR. A really leaky filling will probably release it's Hg in a pulse, then the level will decrease, and if a military veteran was poisoned, he would probably be have been kicked out of the military. Measuring exposure in veterans after years and years, using a test which at best can't even gauge recent exposure reliably, cannot tell you the chronic long term exposure. (Not to mention, suppose those most affected had their amalgams removed , root canals, etc, or they are missing teeth.)
The most accurate studies, many used to be on Boyd Haley's site are fecal tests. Most of the Hg from the filling actually passes through the gastrointestinal tract, not the kidneys or even the bloodstream.
Now, another problem with your analysis is that you are confusing a whole lot of issues. you are saying this study "raises questions about amalgams", but the topic of discussion is increase in Hg release rate due to oils. amalgams , vary wildly in composition, age, galvanic activity and as yes, has been documented in some studies, some amalgams give off hundreds of times more Hg that others. You can't just say, here is a study of 1000 people and THIS is the release rate of Hg from a filling, (even if they didn't use useless blood/urine tests), because that assumes that all fillings give off the same amount of Hg. It is just like me saying, I did a study of airplane safety last year. I studied 300 passengers. The average fatality is .01 people, which is not much, therefore there is no danger of airplanes crashing. You got to look at the exposure in the top 1% using a saliva test , a challenge test, the top .1% with a lot of statistical power (that means 10,000+ people).

Basically stating that while all chemicals introduced into the body have risks (including composites) they can see no special risk to amalgam fillings.
Look at it this way: it is not as if dentists *have* to use amalgams. There are cost effective alternatives. If amalgams were known or suspected to be unsafe, why would they continue to use them? Makes no sense. Who is making money by continuing to use them? The mercury lobby?

The world health organization did a study on amalgam led by expert mats berlin, they concluded the safety margin had been erased, I don't know who this "comission" is couldn't open the document, but certainly "Europe" has not concluded amalgam safe, in fact the opposite.
> Basically stating that while all chemicals introduced into the body have > risks (including composites) they can see no special risk to amalgam > fillings. Risk is a relative term. In this thread you are concerned with whether in oil will increase the risk of amalgam, by Hg. Probably not. But my concern is those with the leakiest amalgam. Assigning a risk to the average person with the average filling is like trying to determine whether cigratte or second hand smoke is dangerous. It's a complex problem

If amalgams were known or suspected to be > unsafe, why would they continue to use them? That is a good question, which I wondered myself. It has to do with the fact that the majority set's the rules, not the smartest or the wisest people. Most people don't understand the science behind amalgam, so there is no political pressure.
you could ask that question of numerous things including, why say cigarettes are safe?, why invade iraq? Why didn't anyone take global warming seriously. What i see in your statements is not a scientific anaylsis or question although you have "cited" references, your argument in the absence of that falls into the bandwagon syndrome, if everyone does that then in must be right. This is precisely WHY most people accept amalgam in the first place, which you have concluded makes the safety "self-evident". Heck, you should be glad that *Most* people by the wrong stocks!
Makes no sense. Who is making
> money by continuing to use them? The mercury lobby? I think you know who, the dental industry, who had no other material for years, and if they admitted the mistake now, would be sued into the next universe. Suppose the ADA declared tommorrow, that billions of mercury implants their dentists had installed, which will be in billions of people for decades are unsafe? Are you that niave?

As you can see even the FDA has conceded that amalgams may be harmful. Archived in the group is a tremendous amount of discussion about studies, both pro and anti-amalgam. I simply don't have time to search the web for studies and unlike many people I do not catalogue them. However I will look for some if I have time. One study, which is relevant to your study, is on the validity of hg blood testing, it is called bimodal distribution of Hg measurements another is the Tubigen study, for it's methodical collection of data. When I have time I will see if I can find the URL. I actually thought the bimodal distribution study was very informative.
You may also be aware that many people, such as Jan frequently post pages of studies on this site, to which dentists reply, they only want to discuss fact's not studies.
Since you seem to have a geniune curiosity about the issue you should also be aware that a filling is a variable reaction product, just like some mixtures of concrete are crap, even if most hold together. What I am talking about in particular, which may only happen to 1 in 1000 is catastrophic corrosion or breakdown of the filling, poorly mixed filling, or extreme immune system breakdown of a filling. That probably isn't relevant to you, your more interested in the statistical average of Hg given off by ALL the fillings ever made, and that is on the order of environmental exposure from other sources, which is significant.

This web page gives the name of the study "urinary hg distribution in micromercurialism". It does an excellent job of describing why blood testing for amalgam Hg is worthless, and presents evidence of measurable micromercurialism from amalgam. It used to be availabe on the web and probably is somewhere, but now they are making you get a subscription.

So tell us, what kind of nuclear reactor is our star ?
How exactly is 'hydrogen' converted to photons ?
What is the best *guesstimate* date of fuel exhaustion for our star ?

Ok, well I tried it. I swished my teeth with olive oil (for about three minutes, not fifteen minutes). I gotta say, made my teeth and gums feel pretty darned good. But I am sure that is simply due to the coating effect, not any "removal of toxins".
