Colgate is the one of the society choosing without any doubt. All are adicted for this but it have so many disadvantages. They don't actually whiten your teeth. Instead, they contains an abrasive that grinds away starin on the enamel, making your teeth seem brighter. Some newspaper reports this paste cause cancer. We didn't know the truth. If we use colgate for other purpose like cleaning car, tiles, etc it seems clean.
