Hi guys ancients indians are using neem stick, salt, charcoal etc to clean their teeths after some day they introduced to tooth pastes, its really good thing and everyone accepted that thing.old peoples in village still use things, they still have strong teeths.i m not saying that using paste is a bad, but concepts introduced by this tooth paste companies are bit misguiding the peoples.few months back colgate comes in new pack with salt added and they started adds with neem. again they come up charcoal we really started remembering old days. few days after these people starts selling tooth paste with chat masala and vodka flavour.really bad thing we all know charcoal is good for teeths then why flouride is added to paste.
