I have been using colgate total now for over a year and am very satisfied with it. the taste is good and has ingredients which not only prevent tooth decay but also prevents possibly gum disease. but it not should be used by people who stay in areas where the drinking water has more than optimal fluoride levels. also it should not be used by children below the age of six years.
it comes with the backing of colgate name which has proven itself in the field of oral health care over the years.
here I would like to add that other fluoride toothpastes are also good and give the same advantage to the consumer. for example pepsodent also contains fluoride and is good .
