Hello, hopefully you have already done something about it and are feeling better. I'm in a very similar situation. I am 26, and I have 9 amalgams, 8 of which are on my upper teeth, and went to a biological dentist. I decided that since my front teeth (no Amalgams there) were fragile, chipped, and going downhill, and with 2 upper root canals already, the best way to go is to get them all pulled and get an upper denture.
My health has suffered in the last few months, with extreme nausea and digestion issues, along with strange almost-numbness in hands and feet, and bizarre pains here and there. Also, brain fog and worsening allergies. All this despite vegetarian, mostly raw diet.
I am convinced that my unhealthy teeth are ruining my health, and so I'm getting rid of all my dead and dying teeth. My dentist said this is important and I feel very strongly that it is. So look at all your options. If your teeth are in bad shape and will be for the forseeable future, take that into consideration.
Good luck and peace~
