Unfortunately, Mercury will never go away until you have the Amalgam fillings removed. I had mine out years ago and I'm still dealing with horrible TMJ. Like you, I only have the popping. Mine's on both sides, but primarily on my right. It's so bad at times that I'm worried it's going to lock. I've also been told that candida and heavy metal toxicity (the mercury in this case) will cause this. Good luck.
