Does anyone know of a good holistic dentist in Maryland?

I have mercury fillings, and while I know a lot of people say it’s harmless, I can taste the metal in my mouth. I’ve been able to taste it for a couple of years now, and in the past year I started to develop eczema and it’s been getting worse. I don’t drink, smoke, I exercise, I eat healthy, so I don’t see what else could be causing it.

I have some small cavities and one is starting to make my mouth sore. The dentist is so expensive and I was wondering if there were any natural remedies to help cavities such as vitamins, minerals, herbs, roots, whatever. i just need to make these cavities better without paying thousands of dollars! Help!
