Flouride toothpaste one of the most obvious product containing flouride. Then there is mouthwash, antibiotics, tap water, vaccine and much much more. Even food items that we consume contain flouride and some of these are: Spinach, Grape Juice and pickles. Flouride is an element and is good for teeth and in 1940's flouride was added to the water to prevent tooth decay and all the products sold were flouride free but in today's day there are plenty of product sold with flouride which suggests that we may be injesting too much flouride that could turn to be harmful for our bodies.

If your child is at the age (younger than 6) which she will swallow some of the paste, it is best to brush with just water. The optimal level of fluoride is 1.1 parts per million. If your area is higher (many are) in fluoride than 1.1 ppm, and you are cooking with said water, best to go with either just water on the brush, or a non-fluoride paste. Too much fluoride can cause discoloration of permanent teeth developing in the jaws.
Too much of anything can be bad.
