Use age appropriate toothbrush and toothpaste to brush your baby's teeth. Please use just a smear of toothpaste for children under 3 years and pea sized amount for children 3 - 6 years.

No, you can't use Glycerine please

If baby teeth aren't brushed properly, bacteria (plaque) might form on the teeth — which can lead to tooth discolouration. Some Infant medications containing iron, such as supplemental vitamins, blood tonic might cause stains on baby teeth. For toothpaste, I will recommend . " milk teeth toothpaste". You can find them in the supermarket or order online
