American Dental Association answeredYou child should begin using fluoridated toothpaste once old enough to spit out the toothpaste. This is typically around age 2. The fluoride in toothpaste helps prevent tooth decay and has been shown to be safe and effective for both children and adults.
Fluoridated toothpaste does prevent dental caries or cavities. So you should use fluoridated toothpaste for your children. However, small children are more apt to swallow the toothpaste while they're brushing their teeth than older children. So you should start with a toothpaste that does not have fluoride, and when your baby, or your infant, I should say, consistently is able to spit the toothpaste out when you brush their teeth and not swallow it, then you can change over to the fluoridated toothpaste. That's about 2 years old.
