Has anyone had their mercury filling removed?

I’m seeing more and more about how toxic they are and ppl having side effects from them. I have a few health issues that I think relate to my fillings (I have alot of them)

Has anyone gotten them removed

How expensive was it?

Was it worth it?

How did you find a clinic to do it? I’m reading a lot about how you have to find a dentist that specializes in removing them.
