We were using Colgate tooth paste from many years but now it’s become too harsh to use for us.first my mother in law affected by it.she get cut whenever use twice a day.then my husband and other member also faced same kind issue .Colgate has big number of harsh chemical now I think they make it more concentrated now.because we are having oral soreness and some related issues.moreover Colgate is quite costly then other tooth paste.it means give money to waste first money and then health and keep going to dentist also
