    Hi there,
    I have had a Chromium and Cobalt crown (which does not contain mercury) for about two years now, and since just over one year, I have been experiencing weird symptoms such as fatigue and difficulty to concentrate and memorize. The percentage of Chromium in the crown is 24,8 (it doesn't say whether it's mass percentage or atomic percentage). Is that a reasonable amount or is it possible that it is slightly and slowly poisoning me ? My dental surgeon gave me the document that holds all this information and she told me to take it to a specialist if I have any doubts. Does anyone know what I should do ? Have it removed ? How ? I'd be grateful to get help, I'm a bit worried. Thanks in advance.

    I would doubt the crown is at fault. However, your symptoms appear to be something that should concern you, and you should see a doctor about them. You may have a virus illness, or some other condition causing the problem. You cannot diagnose that by questions in a science forum. See a doctor.

    Sure, I'm not trying to get a diagnosis on the forum, I've done loads of tests and nothing has been found so far, and the crown was just a new idea that I came up with.
    Right now I'm studying in France, and the French health authorities are just liars : they claim that mercury, chromium and all of those poisonous metals are safe, cause they can't be bothered to call back all the unsafely treated patients and pay for replacement. Therefore doctors here have no idea what to do with patients like me who come up to them suspecting that their symptoms are caused by something which is officially considered to be harmless.
    So I don't have any experts to advise me, and I'm hoping someone in the know will hit on this discussion.

    It is not possible to say that chromium, mercury etc are safe, since it all depends on the form the metals are in.

    Methyl mercury is horrendously toxic, but the mercury amalgum used in dental fillings is generally very safe. Chromium as the chrome 6 salt is very dangerous. But stabilised chrome should be quite safe. Actually, chromium 3 salts are an essential dietary mineral.

    If the French health authorities say the mix is safe, then they are probably correct.

    I did hear about something of that kind, but they never actually mention which ions are the ones formed in my mouth when the solid chrome is in contact with my saliva. Anyway thanx !
