Did you know that the American Dental Association recommends the use of fluoride containing toothpaste for dental care beginning with the eruption of the first tooth? A child from 6 months to 3 years should use a “smear” or an amount the size of a grain of rice. A child from 3 to 6 years requires a pea sized amount. These amounts are considered safe twice a day even if the child is unable to spit it out.
