Why not use MI Paste/MI Paste PLUS as a dentifrice?
The reason why you wouldn’t want to use it as a dentifrice is because it is “sticky” which gives it the substantivity. Having the milk protein in it, with most toothbrushes, more of it will stick to the bristles of the brush than when you use the tray or finger technique. The patient would be wasting too much product in the bristles of the toothbrush and not on the tooth surfaces. We want the patient to get the most use out of her tube of MI Paste. Also, most people rinse after brushing and again this would defeat the benefit of MI Paste.
