Until your child is able to completely spit out all of their toothpaste, fluoridated toothpaste should not be used. For young toddlers, brushing with a toothbrush and water is usually sufficient enough. Non-fluoridated toothpaste can also be used but should always be encouraged to be spit out to help build good habits.

If a child consumes fluoridated toothpaste, dental fluorosis of the adult teeth can occur. Dental fluorosis is when the the enamel does not form properly and appears with bright white and brown pitted stains. Dental enamel affected by dental fluorosis also does not form as strong as it normally would, and is therefore more prone to cavities.
