Do not use fluoridated toothpaste until age 3 if its manageable. Earlier than that, clean your child's teeth with water and a soft-bristled toothbrush. After age 3, parents should supervise brushing. Use no more than a pea-sized amount of toothpaste and make sure children do not swallow excess toothpaste.

 This is why the IDA requires a poison warning on every tube of fluoride toothpaste now sold . Risks from ingesting fluoride toothpaste include permanent tooth discoloration (dental fluorosis), stomach ailments, acute toxicity, skin rashes (perioral dermatitis), and impairment in glucose metabolism.
