Guest guest Posted June 30, 2005 Report Share Posted June 30, 2005 OK, unable to let go of this one! As usual! First, teeth vary a lot in how hard they are. But the moh listing of teeth is that they have a hardness of 5: http://www.efunda.com/units/hardness/convert_hardness.cfm?cat=Steel & HD=HM The hardness of bentonite is 6-7. So, it would potentially abrade enamel. Which makes sense: silicates are used for polishing. http://ceramic-materials.com/cermat/material/1264.html I came across something interesting though: they HAVE studied tooth remineralization using toothpastes. Saliva (and cheese) can also remineralize, though I guess this toothpaste does it faster! http://www.jclindent.com/Abstracts/Munoz_v1015.html Restorative treatments by the remineralizing and conventional toothpastes significantly increased the hardness of the acid soft drink-weakened enamel by 12.1% and 7.3%, respectively. Both toothpastes were effective in inhibiting damage due to acid soft drink exposure, but the remineralizing toothpaste was more effective in hardening intact and decalcified enamel than the conventional toothpaste (p < 0.05). -- Heidi Jean Quote Link to comment Share on other sites More sharing options...
