Oil pooling is relatively simple. Take a heaping teaspoon of coconut oil and put it in your mouth and swish it around and leave it in there as long as possible. This will pull heavy metals from your mouth. It also effects metal fillings but it will not damage them. It will remove dangerous heavy metals from your mouth. Do not split the solution into the sink because it will harden and clog your drains. This must be spit out in your garbage can to preserve the sink drain integrity.
