Our dentist has suggested to use this colgate anticavity toothpaste for my son.he has some problem of tooth decaying.i have bought that colgate tooth paste for my kid and started using as per doctors advise. After 2 weeks, we feel that difference which the dentist said.my sons case is almost improved.my son is using this toothpaste twice(in the morning and before bed)when brushing.he also very interested to use this particular toothpaste because of its bubble fruit flavour.this paste gives the enamel ptotection too.it is sufficiently good for children at 6 or above.
