Could a permanent retainer cause perioral dermatitis?

I have developed a weird, ugly dermatitis on my face that fits the perioral profile. The etiology is unknown, but there's a long list of suspects: all manner of personal care products, cosmetics, fluoride, fake cinnamon flavoring, food allergies, chemicals, medications, etc. I've tried many things %26amp; spent a lot of money trying to fix this problem, but it's still there. Now I'm wondering if the retainer I've had for 18 years could have anything to do with it. It's a long time to have a metal/cement thing in one's mouth. I know that the ADA claims fillings are totally stable %26amp; none of the material is absorbed into the body %26amp; all so no doubt that would be the official word about orthodontic appliances, as well. Studies show that fillings can certainly degrade and affect the body, though, so I worry that maybe I should get this thing out of my mouth. It's obviously different than a filling but does anyone know if this permanent orthodonture can be harmful to health?

Could a permanent retainer cause perioral dermatitis?
Not harmful to your health, but that does not mean that it could not cause some annoyances. In rare circumstances it has been documented that a person could be sensitive to many metals. Two metals that I have never heard of causing trouble are titanium, and gold. Both substances could be used to fabricate dental appliances, but gold is far more common.
Reply:sorry i'm not really answering your question, but for the perioral dermatitis you should try metronidazole (a kind of antibiotic, usually 250mg 2xdaily and after several weeks only one). this really gets rid of it and quickly - you will see results within days. the pills aren't great - you must take them for several months and you can't drink any alcohol while taking them but it is really worth it. i was very depressed because of perioral dermatitis but was lucky enough to come across a good dermatologist who recommended this treatment.
