Fluoride Action Network

Toothpaste and Toothbrushing: a new report by the CDC.

Fluoride Action Network | February 4, 2019

The report was released on February 1, 2019: Use of Toothpaste and Toothbrushing Patterns Among Children and Adolescents — United States, 2013–2016Morbidity and Mortality Weekly Report, by Thornton-Evans G1, Junger ML1, Lin M1, Wei L2, Espinoza L1, Beltran-Aguilar E2.

It’s called a “CDC report” because four1 of the authors are with the Division of Oral Health at the Center for Disease Control and Prevention (two2 work for DB Consulting Group, Inc., Atlanta, GA).

There were 1,686 children in the age group 3-6 years, for which 38% used more than the recommended amount of toothpaste “exceeding current recommendation for no more than a pea-sized amount (0.25 g) and potentially exceeding recommended daily fluoride ingestion (1,6).”

The CDC noted that “ingestion of too much fluoride while teeth are developing can result in visibly detectable changes in enamel structure such as discoloration and pitting (dental fluorosis) (1). Therefore, CDC recommends that children begin using fluoride toothpaste at age 2 years. Children aged <3 years should use a smear the size of a rice grain, and children aged >3 years should use no more than a pea-sized amount (0.25 g) until age 6 years, by which time the swallowing reflex has developed sufficiently to prevent inadvertent ingestion.”

The CDC recommended “that all persons drink optimally fluoridated water (0.7 mg/L)” without any warning for pregnant women, formula-fed infants, people with kidney disease, or those with allegies to fluoride.

The CDC noted these limitations to the report:

  • “First, the measures used are based on parents’ self-report, so reporting bias is possible.
  • “Second, the question about the amount of toothpaste used focuses on the amount currently used and therefore might overestimate the amount that was used at younger ages.
  • “Finally, the type of toothpaste (fluoride versus nonfluoride) was not specified.”

The CDC used 5 references for dental fluorosis dated 1988, 1992, 1994, 2014, and 2015. Surprisingly none included direct references to NHANES (National Health and Nutrition Examination Surveys) data on dental fluorosis which has documented significant increases in dental fluorosis in U.S. children between 1986 to 2012. For example:

Neurath et al. (2019, in press) reported NHANES data on dental fluorosis for 12-15 year olds: 22% (1986-1987), 41% (1999-2004) and 65% (2011-2012). Wiener et al. (2018) looked at the NHANES data for a different age group, and reported: “There was a difference of 31.6% in dental fluorosis prevalence between 2012-2011 when compared to data from 2002-2001 in adolescents aged 16 and 17 years.”
