toothpaste

That day when I was sitting for my oral health test, one of the questions asked
What are the ingredients of toothpaste?

Oh o.. I didnt know the answers..
After google-ing a while in the net, I found lots of answers...

Fluoride(of course) -- stannous fluoride, later sodium monofluorophosphate, then sodium fluoride.--remineralising activity.
Hydrated silica-abrasive
sodium lauryl sulfate, or ammonium laurly sulphate (surfactant)- aids fluoride activity, help clean the teeth, and provide a foam that helps to carry away debris, lauryl sulfates have significant anti-bacterial properties, and they can penetrate and dissolve plaque.
Sodium bicarbonate--for mouth taste
Sodium carbonate peroxide--whitening
Triclosan--antibacterial
ANd lots more...
