A couple of things to note: fruit is very acidic, so drinking smoothies out of fruit every day will quite likely erode your tooth enamel.
in a ratio of 1 drop mms to 4 drops citric acid
will also be pretty acidic.
Also, swishing for three minutes is a long time as far as chloring dioxide is concerned - at least two minutes too long - therefore exposing your teeth to acidity unnecessarily.
I would suggest stopping drinking the smoothies and eat the berries instead (more fibre that way) and make sure to eat them at meal times, not in between, when your mouth is better able to neutralise the acid.
Also, if you want to use Miracle-Mineral-Supplement
as a mouthwash, maybe a 1:1, or 1:2 ratio of Miracle-Mineral-Supplement
to citric acid
would be better as it's less acidic. You could test it with PH strips to find the most neutral mixture.
Also, only swish for a minute or less, and don't do it every day. Once or twice a week should be plenty to keep the plaque at bay.
I agree that the MMS radically reduces tartar. I went to the dentist yesterday and she was amazed that there was nothing to clean!
