Since you have only two amalgams, and you have only had them for around 2 years, there is a good chance that they aren't causing your problems. What if they are though, or if they are contributing to your problems? Perhaps if the amalgams are not removed now, they might cause problems later? Getting them removed will give you peace of mind if nothing else. Make sure that you aren't eating fish high in mercury such as tuna and swordfish.
