Iam using colgate from past 6 months.before using colgate I face many problems in my mouth like yellow teeth, bad smell , decaying teeth and dental caries.but I overcome all these problems by using colgate.Colgate flavour is too good we can enjoy its flavour while brushing teeth.my yellow teeth became white with in a 1 month.After brushing the teeth I observe mouth fressness stands long upto 12 hours .so I used to brush 2 times a day.Colgate has many beneficial effects like prevention of bad smell , turning yellow teeth into white , freshness of mouth for long time etc.So friends if you want porper oral hygiene use colgate like me.
