my son is now 22 months old, kya use toothbrush karna chahiye,aur kis toothpaste se , please suggest me sir

A. Use a small, soft toothbrush designed for your child's age. Use water on the toothbrush until your child is 18 months old, unless a dentist tells you otherwise. From 18 months to 3 years, you can start using a smear-sized amount of low-fluoride toothpaste, unless a dentist recommends otherwise.
