Often you can have an infected root in a tooth and you don't even know.
Maybe a bit of bleeding when you brush your teeth.
That can have an effect on the rest of your body without knowing.
As far as amalgam fillings go...........I started getting skin problems at about the age of 12(early ' 70s). Dry itchy skin. Went to the doctor and got prescribed hydrocortisone, betnovate.......all sorts of other things that never did a lot apart from thinning the skin. Pine tar lotions.....all sorts.
At the same age........through the NHS (England)......we went to the dentist every 3 months for free, got lots of fillings, no needle, just drill and fill. Mainly caused by lots of lollies and lack of proper brushing.
Skin problems got progressively worse.
I've even been referred to the skin specialist at the local hospital in Wellington NZ.......no help whatsoever. He said I've just got sensitive skin and need to "manage it" properly.
My brother is a doctor now (in Hobart, Tas) He told me that in 6 years at med school, they had about 1 day on "skin".
Fast forwards 15 years.(in my early 20s)......I was working with a bloke who commented on my continuous scratching.......he mentioned that he used to have the same problems but it just went away one day.
So what happened for it all to go away?
He said he didn't know but it was about the same time he had all his teeth pulled out.
I didn't think too much of it at the time but about 15 years after that (30 odd years of suffering) I had my amalgam fillings all removed, had some teeth pulled too, one had an unknown deep root infection.
Within 3 months most of my skin problems were gone and within 2 years, they'd ALL gone. I haven't needed any medication since. I used to scratch all the time to the point of bleeding,my back, insides of joints, behind knees, feet............and hard dry skin on my elbows. When you scratch all the time you eventually get an infection so end up on anti biotics. Also have to keep the fingernails cut to minimise damage to yourself.
Prior to having my amalgam fillings removed, I'd been to the doctor and got myself tested for both lead and mercury levels (I use solder every day)...both came back as zero.
Since then I've read that amalgam fillings can be responsible for not just skin problems but other disorders like depression....and others.
Sorry, not related to shingles vaccine but it might help someone else.
