The warning cautions thats can be read it on toothpaste label:

“WARNING: Keep out of reach of children under 6 years of age. If you accidentally swallow more than used for brushing, seek professional help or contact a poison control center immediately.”

Why the Need for a Warning?

One of the little-known facts about fluoride toothpaste, is that each tube of toothpaste – even those specifically marketed for children – contains enough fluoride to kill a child.

Most “Colgate for Kids” toothpastes – with flavors contain up to 143 milligrams (mg) of fluoride in each tube. This dose of fluoride is more than double the dose (60mg) that could kill the average-weighing 2 year old child. It is also greater than the dose capable of killing all average weighing children under the age of 9.
