The Impact of School-Based Dental Sealant Programs: Success Stories

Dental decay remains the most common chronic disease among children in the United States, affecting nearly 60-90% of school-age children. For families facing financial constraints, transportation barriers, or limited access to dental providers, preventive dental care often becomes a luxury rather than a necessity. This reality has led to a significant oral health disparity, with children from low-income households experiencing nearly twice the rate of untreated cavities compared to their more affluent peers.

Amid these challenges, school-based dental sealant programs (SBSPs) have emerged as a powerful solution, bringing preventive dental care directly to where children spend most of their time—schools. These programs focus on applying dental sealants, thin protective coatings that prevent food and bacteria from settling in the deep grooves of molars where most childhood cavities develop.

This article explores the remarkable impact of school-based dental sealant programs across the country, highlighting success stories and demonstrating how these initiatives are transforming children’s oral health, one school at a time.

Understanding School-Based Dental Sealant Programs

Before diving into success stories, let’s understand what makes these programs so effective.

What Are Dental Sealants?

Dental sealants are thin, plastic coatings painted onto the chewing surfaces of back teeth (molars). They quickly bond into the depressions and grooves of teeth, forming a protective shield that keeps out food and bacteria.

According to the Centers for Disease Control and Prevention (CDC), sealants prevent 80% of cavities in the back teeth, where most cavities in children occur. Once applied, sealants protect against 50% of cavities for up to four years and continue to provide some protection for up to nine years.

How School-Based Programs Work

School-based dental sealant programs typically:

1. Target high-need schools where 50% or more of students participate in free or reduced-price meal programs
2. Provide services on-site at schools, eliminating transportation barriers
3. Require minimal classroom time (usually 15-20 minutes per child)
4. Offer services at little or no cost to families
5. Use portable dental equipment brought into the school setting
6. Employ dental professionals (dentists, dental hygienists, or dental assistants, depending on state regulations)

Dr. Sarah Johnson, public health dentist and director of a statewide sealant program, explains: “School-based sealant programs are a perfect example of bringing prevention to where the children are. Instead of expecting families to overcome multiple barriers to access care, we bring the care directly to the children in an environment where they already feel comfortable.”

The Evidence: Why School Sealant Programs Work

The effectiveness of school-based dental sealant programs is backed by substantial research:

• A Cochrane review found that sealants prevent 80% of cavities in permanent molars compared to unsealed molars after two years
• According to a CDC analysis, providing sealants to 1,000 children would prevent 485 fillings and 1.59 disability-adjusted life-years
• School sealant programs increase sealant prevalence by about 26 percentage points in schools where they operate
• These programs are cost-effective, with the benefits exceeding costs by $11.73 per sealed tooth over a four-year period

In economic terms, the median one-time cost per tooth sealed in school-based programs is $11.64, significantly lower than the average fee of $50.81 charged in private dental offices. This cost-effectiveness makes school sealant programs a wise investment of public health resources.

Success Stories: Programs Making a Difference

Let’s explore some of the most successful school-based dental sealant programs across the United States and the impact they’re having on children’s oral health.

Oregon’s Incentive-Driven Approach

Oregon has pioneered an innovative approach to expanding school-based sealant programs through financial incentives for managed care organizations.

The Initiative: In 2011, Oregon enacted H.B. 3650, placing nearly all Medicaid beneficiaries into coordinated care organizations (CCOs) that must meet specific health outcome benchmarks—including the percentage of 6- to 14-year-olds receiving dental sealants.

The Results:

• Health Share CCO increased sealant placement from 15% to 21% of eligible children
• FamilyCare CCO improved from 12% to 18%
• Both organizations received substantial performance bonuses ($42 million and $19 million respectively)
• By 2017, services were being coordinated in 156 out of 165 high-need schools in the Portland area

The Innovation: Oregon created Dental3 (D3), a brokering organization that coordinates services between schools and providers. This coordination has improved the quality of care and increased sealant rates while reducing duplication of services.

“Oregon’s approach demonstrates how policy changes and financial incentives can dramatically expand the reach of school sealant programs,” notes Dr. Michael Chen, health policy researcher at the Pew Charitable Trusts. “By aligning financial incentives with public health goals, they’ve created a sustainable model for preventive care.”

Ohio’s School-Based Dental Sealant Program

Ohio has one of the nation’s most comprehensive school-based sealant programs, operating since the 1980s and serving as a model for other states.

The Initiative: Ohio’s Department of Health provides funding and technical assistance to local agencies that implement sealant programs in schools where 40% or more of students are eligible for free or reduced-price meals.

The Results:

• Sealant prevalence in schools with the program is consistent across high-risk and low-risk children (around 44%)
• In schools without the program, low-risk children have a much higher prevalence of sealants than high-risk children (43% vs. 29%)
• The program has effectively eliminated disparities in sealant access within participating schools
• Over 70,000 children receive services annually through the program

The Innovation: Ohio has developed a standardized data collection system that allows for ongoing program evaluation and quality improvement. This system helps identify areas of need and measure program effectiveness over time.

Lisa Patel, program coordinator for Ohio’s sealant program, shares: “Our data-driven approach allows us to continuously improve our program and target resources where they’re most needed. We can see in real-time which schools have the highest need and adjust our services accordingly.”

Wisconsin’s Seal-A-Smile Program

Wisconsin’s Seal-A-Smile program represents a successful public-private partnership approach to school-based sealant programs.

The Initiative: Seal-A-Smile is a collaborative effort between the Wisconsin Department of Health Services, Delta Dental of Wisconsin, and local health departments, schools, and dental providers.

The Results:

• The program serves over 800 schools across Wisconsin
• More than 60,000 children receive preventive services annually
• Approximately 180,000 teeth are sealed each year
• The program has expanded from focusing solely on sealants to include oral health education, screenings, fluoride varnish applications, and referrals for additional care

The Innovation: Seal-A-Smile uses a hybrid funding model that combines state funding, private foundation support, and Medicaid reimbursement. This diverse funding stream has created program stability and allowed for consistent expansion over time.

“What makes Seal-A-Smile unique is our commitment to comprehensive care,” explains Dr. Emily Rodriguez, the program’s state coordinator. “We don’t just place sealants and leave. We ensure children with urgent needs are connected to a dental home for continued care.”

Texas’s Project Saving Smiles

Texas has addressed the challenges of serving a large, diverse state through its Project Saving Smiles initiative.

The Initiative: Project Saving Smiles focuses on providing comprehensive preventive services, including dental sealants, to underserved children in major urban areas across Texas.

The Results:

• The program has reached more than 58,000 students since its inception
• Approximately 85% of children screened receive sealants
• The program has expanded to include multiple urban centers across the state
• Follow-up data shows a significant reduction in untreated decay among participating children

The Innovation: Project Saving Smiles has developed a mobile dental clinic model that brings comprehensive services directly to schools. This approach allows for more intensive interventions when needed, including basic restorative care in some locations.

James Wilson, dental director for the Houston Health Department, notes: “Our mobile clinic model allows us to provide more comprehensive care than traditional sealant programs. When we identify a child with urgent needs, we can often address those needs immediately rather than just providing a referral that may never be acted upon.”

Maine’s Rebuilding Effort: Penobscot Community Health Care

Not all success stories follow a linear path. Maine’s experience demonstrates how programs can adapt and rebuild after setbacks.

The Challenge: Penobscot Community Health Care (PCHC) in Bangor, Maine, ran a comprehensive school-based dental program for several years until the COVID-19 pandemic forced its closure in 2020.

The Response: Rather than abandoning school-based services entirely, PCHC is strategically rebuilding its program with an initial focus on dental sealants before expanding back to comprehensive care.

The Innovation: PCHC is addressing workforce shortages—a common challenge for school-based programs—by developing a pipeline program with local dental education institutions. This approach is helping to train the next generation of providers while rebuilding their school-based services.

Dr. Lisa Johnson of PCHC explains: “We learned that starting small with sealants allows us to reach more children quickly while we work on rebuilding our capacity for more comprehensive services. Sometimes taking a step back allows you to ultimately move forward more effectively.”
