You can begin using fluoride toothpaste after the eruption of their first tooth! Using a rice-sized amount (under the age of 3 years) or pea-sized amount (3-6 years) appropriate to the child’s age, will aid in the prevention of early childhood cavities. We recommend parents supervise and place fluoridated toothpaste on their child’s toothbrush to ensure the proper amount is applied. This small amount is enough to be safe and effective in the prevention of cavities. Parents should encourage their children to spit out any excess toothpaste.
