Does anyone have recently updated information about HMD (2017, 2018)? I just had several Amalgam fillings removed and upset that the dentist didn't use all the SMART protocol procedures such as saliva ejector and nasal mask. Consequently I'm concerned I was breathing in the mercury vapors and possibly swallowing tainted saliva. I'd like to chelate safely. Andy Cutlers, HMD, Quick Silver, etc... difficult to tell which is the best and safest. Thanks in advance for experiences and suggestions.
