ADA Statement on Study in JAMA Pediatrics

August 19, 2019

CHICAGO - The American Dental Association (ADA) remains committed to fluoridation of public water supplies as the single most effective public health measure to help prevent tooth decay. This commitment is shared by many national and international organizations, including the World Health Organization, US Public Health Service, the Centers for Disease Control and Prevention, the American Medical Association and the American Academy of Pediatrics. 

Public health policy is based on a collective weight of scientific evidence. The ADA is aware of a new study conducted in Canada in which its authors reviewed maternal exposure to fluoride in pregnancy. We welcome this and further scientific study of the issue to see if the findings can be replicated with methods that demonstrate more conclusive evidence.

Throughout more than 70 years of research and practical experience, the overwhelming weight of credible scientific evidence has consistently indicated that fluoridation of community water supplies is safe. The evidence-based research shows the recommended concentrations of fluoride (0.7 mg/L) used in community water fluoridation is beneficial and safe for the public.

Since the introduction of community water fluoridation in 1945, and the addition of fluoride in toothpaste, tooth decay rates in the U.S. have dropped significantly. Today, even with wide-spread availability of fluoride toothpaste, studies show community water fluoridation continues to be effective in reducing tooth decay by more than 25 percent in children and adults.

The ADA remains focused on how and if emerging evidence might impact public health recommendations and policies. We will continue to evaluate the validity of emerging evidence and research to support the advancement of the health of the public. To learn more about the benefits of fluoride, please visit

Off-Setting Oral Health Disparities Among Low-Income Americans


(BUSINESS WIRE) -- The benefits of good dental care can result in more than just a pretty smile. And as National Children’s Dental Health Month gets underway, healthcare providers are encouraging parents to help their children develop good oral health habits that can lead to a lifetime of overall health and wellness. According to the Centers for Disease Control (CDC), tooth decay, or cavities, is one of the most common chronic childhood conditions in the United States occurring more among children from low-income or minority families. Studies show:

Poor dental care can cause serious health problems beyond the mouth and teeth. AmeriHealth Caritas urges parents and caregivers to help children learn how to take proper care of teeth to support future health.

• Tooth decay is prevalent among 25 percent of children from low-income families – more than double that of children from higher-income families (11 percent).

• African American youths had the most untreated cavities, 17.1 percent compared with Hispanic (13.5 percent) white (11.7 percent), and Asian (10.5 percent) youth.1

The American Dental Association has tracked the historical trend of racial disparity in oral health care -- and its correlation to income levels -- over several decades, finding that as family income levels increase, the prevalence of untreated cavities and tooth decay decreases.2 Socioeconomic factors and a lack of access to healthcare may contribute to poor dental health for children – problems that, if untreated, can continue as children enter adulthood. AmeriHealth Caritas, a national leader in Medicaid managed care, offers dental benefits to help reduce oral health disparities among children and adults in greatest need.

Failure to maintain good dental hygiene for children can lead to a variety of problems in addition to tooth decay, including halitosis (also known as chronic bad breath), gum disease, and even tooth loss. Additionally, tooth decay can adversely impact a child’s ability to eat, speak and learn.

“The earlier you get a child to the dentist, the better. The more proactive you are about a child’s dental care, the more you can know about his or her dental health and the more likely you are to avert problems down the road,” said Lawrence Paul, DDS, vice president of Corporate Dental with AmeriHealth Caritas.

Poor dental care can also cause serious health problems beyond the mouth and teeth. Research shows that neglecting dental hygiene can be linked to diabetes, pancreatic cancer, and heart disease.3 In very rare cases, tooth decay can be deadly, Dr. Paul added, referencing the tragic case of a 12-year-old Maryland boy who died in 2007 due to a severe brain infection caused by dental decay.

"Oral disease can have an impact on physical, psychological, social, and economic health and well-being through pain, diminished function, and reduced quality of life,” Dr. Paul said. “So it’s vitally important that parents and caregivers know how to best care for the dental needs of their children, showing them how to properly brush and floss so they eventually know how to care for their teeth on their own.”

An early start to good dental hygiene can help develop lifelong habits that contribute to healthier and happier outcomes. Some simple advice to preventing dental problems includes:

Go For Two – Children should brush their teeth twice a day for two minutes. Most municipalities have fluorinated water, but it’s also worthwhile to brush using toothpaste with fluoride, a natural mineral that strengthens tooth enamel and prevents cavities. For young children, parents and caregivers should monitor their children to ensure they are properly brushing all of their teeth and that they avoid swallowing toothpaste, which can upset the stomach and cause gastrointestinal problems.

Get Flossy With It – Even brushing twice a day won’t get rid of all the food and plaque that can become stuck in between teeth. Children should floss once a day to ensure that their teeth are completely clean.

An Apple a Day Keeps Tooth Decay at Bay – Children that have diets low in sugar are less likely to develop cavities or other problems with their teeth. Dr. Paul says children (and adults!) should eat foods that have cleansing effects, such as fruits and vegetables, especially apples. The American Dental Association adds that children should drink plenty of water and eat a variety of foods in addition to fruits and vegetable, including whole grains, lean sources of protein and low-fat dairy foods.

First Things First – Children should see a dentist soon after their first tooth appears or by their first birthday – whichever happens first. The best way to stay on top of dental health is for children to be seen by their dentist twice a year.

Alliance for a Cavity-Free Future Grants to Improve Oral Health of Young Children

Toronto, (Jan. 15, 2019)

(PRNewswire) -- The Canada-United States Chapter of the Alliance for a Cavity-Free Future (ACFF) has awarded four interprofessional grants totaling over $50,000.00 (USD) to fund projects that will have a positive impact on reducing the instance of dental caries, which is reversible, for children aged 0-6. These projects will be carried out in 2019.

The grant program aims to bring together groups outside of dentistry, such as pediatrics and primary care, to help underserved communities. Made possible through funding from Colgate-Palmolive, the grants focus on populations with high caries needs and disadvantaged communities such as those with low incomes and or limited access to care.

Worldwide, 60–90% of school children and nearly 100% of adults have tooth decay.i In fact, dental caries (which includes all stages of tooth decay) is the most common, yet preventable, chronic disease on the planet. The impact of this disease has a profound impact on children in North America. In Canada, an estimated 2.26 million school days are missed each year due to dental related illness.ii In the United States, a child is five times more likely to seek emergency room treatment for dental problems than for asthma, often because they can't see a dentist, are uninsured or can't afford routine dental care.iii

"This grant funds projects that exemplify recognition of the need for interprofessional collaboration to address oral health needs," said Robert Schroth, Associate Professor in the Department of Preventive Dental Science (Dr. Gerald Niznick College of Dentistry) and the Department of Pediatrics & Child Health (Max Rady College of Medicine), University of Manitoba, and Co-Chair, Canada-U.S. Chapter of the Alliance for a Cavity-Free Future. "It is through working together that we can find the best solutions and provide the most thoughtful approaches to prevent dental caries."

Since the first of these grants were awarded in 2016, the program has been able to fund four recipients this year, with programs that will aim to improve the oral health of children in various localities.

"We are very excited to have the opportunity to fund so many much-needed projects this year," said Margherita Fontana, DDS, PhD, Professor, University of Michigan School of Dentistry, and Co-Chair, Canada-U.S. Chapter of the Alliance for a Cavity-Free Future. "We believe these programs will have a significant impact on our ability to understand how interprofessional efforts can help address dental caries disparities."

ADHA Supports Upcoming Update to Surgeon General’s Report on Oral Health

Chicago, IL (August 1, 2018)

The American Dental Hygienists’ Association (ADHA) applauds the federal agencies that will be involved in updating the Surgeon General’s Report on oral health. This update will document progress in oral health over the last 20 years and create a vision for the future.

The U.S. Department of Health and Human Services announced the update on July 27 and is working alongside several federal agencies to commission this Surgeon General’s Report.

The original Surgeon General’s Report on oral health was first released in 2000 and evaluated the link between oral health and overall well-being. The updated report will further assess how poor oral health affects physical and economic well-being, how oral health care is often treated as a supplemental benefit and more.

ADHA commends these efforts to update the nation on key issues in oral health and will continue to support the updated report as it is developed.
