Here is another suggestion from the great book „Holistic Dental Care“, but it is not about teeth this time: It is for the whole body. You can use clay like betonite clay to detoxify your body. For a clay bath follow these instructions:
Run a warm-water-bath and add baking soda and clay together with a few drops of lymph-stimulating and immune-enhancing oils like juniper, grapefruit or cypress and enjoy a long and cleansing bath. Betonite clay is perfect for this type of detox and you can also use it for local application in case of an inflamed part of your body (like the gums or pimples on your face). You can always enhance its effect by adding essential oils of your choice.
Be well and see you soon!
