Tooth Paste - Do we Neet It? Is Water Enough?

Yes, ofcourse we need it I think water is not enough just use to brush your teeth twice a day

I remember about 15 Years ago doing an experiment in school. We took two eggs covered one in toothpaste and left one plain. We then put both eggs in Coca Cola. The egg covered in the toothpaste remained pretty much whole, the other one was starting to crumble - this was always enough reason for me to brush my teeth!!
