Is not using fluoride toothpaste bad for a 8 years old boy?

If he likes having cavities in his teeth this is one way to assure they have a chance to develop. Privative man didn't have toothpaste much less the fluoride that helps make teeth decay resistant. Of course their teeth often fell out or were decayed beyond repair by their adult years. A simple answer is yes it is bad to avoid the best dental products available.

When I was a kid we didn't have fluoridated products available, and we all had mouths full of cavities that required "drill and fill." Fluoride works audits safe in the proper dose. For example your child should be using a pea-sized portion of toothpaste. Talk to his Dentist about t'pastes, varnishes, mouthwashes, etc, that your son can use.
