18 months is safe, according to Colgate-Palmolive (PNG).
Colgate has a program called 'Mum You First' that educates mothers and caregivers of 18-month-old babies in medical health centres on how to introduce good oral health practices to their children early.
Most 18 month old babies can be involved because it is their last immunisation and is also safe to introduce supervised teeth brushing at this age.
