Doctors take on dental duties to reach low-income and uninsured patients

DENVER — Pediatrician Patricia Braun and her team saw roughly 100 children at a community health clinic on a recent Monday. They gave flu shots and treatments for illnesses like ear infections. But Braun also did something most primary care doctors don't. She peered inside mouths searching for cavities or she brushed fluoride varnish on their teeth.

"We're seeing more oral disease than the general population. There is a bigger need," Braun said of the patients she treats at Bernard F. Gipson Eastside Family Health Center, which is part of Denver Health, the largest safety-net hospital in Colorado, serving low-income, uninsured, and underinsured residents.

Braun is part of a trend across the United States to integrate oral health into medical checkups for children, pregnant women, and others who cannot afford or do not have easy access to dentists. With federal and private funding, these programs have expanded in the past 10 years, but they face socioeconomic barriers, workforce shortages, and the challenge of dealing with the needs of new immigrants.

With a five-year, $6 million federal grant, Braun and her colleagues have helped train 250 primary care providers in oral health in Colorado, Montana, Wyoming, and Arizona. Similar projects are wrapping up in Illinois, Michigan, Virginia, and New York, funded by the federal Health Resources and Services Administration's Maternal and Child Health Bureau. Beyond assessment, education, and preventive care, primary care providers refer patients to on- or off-site dentists, or work with embedded dental hygienists as part of their practice. 

"Federally qualified health centers have a long history of co-locating dental services within their systems," Braun said. "We're taking that next step where care is not just co-located, meaning, say, we're upstairs and dental is downstairs, but we're integrated so that it becomes part of the same visit for the patient."

Having doctors, nurses, and physician assistants who assess oral health, make referrals, and apply fluoride at community health centers is critical for the many children who lack access to dental care, said Tara Callaghan, director of operations for the Montana Primary Care Association, which represents 14 federally qualified health centers and five Urban Indian organizations.

"Providing these services during medical visits increases the frequency of fluoride application," Callaghan said, and "improves parents' knowledge of caring for their child's teeth." But obstacles remain.

Because of Montana's large geographic area and small population, recruiting dental professionals is difficult, Callaghan said. Fifty of the state's 56 counties are designated dental shortage areas and some counties don't have a single dentist who takes Medicaid, she added. Montana ranks near the bottom for residents having access to fluoridated water, which can prevent cavities and strengthen teeth.

Pediatric dental specialists, in particular, are scarce in rural areas, with families sometimes driving hours to neighboring counties for care, she said.

Embedding dental hygienists with medical doctors is one way to reach patients in a single medical visit.

Valerie Cuzella, a registered dental hygienist, works closely with Braun and others at Denver Health, which serves nearly half of the city's children and has embedded hygienists in five of its clinics that see children.

State regulations vary on which services hygienists can provide without supervision from a dentist. In Colorado, Cuzella can, among other things, independently perform X-rays and apply silver diamine fluoride, a tool to harden teeth and slow decay. She does all this in a cozy corner office.

Braun and Cuzella work so closely that they often finish each other's sentences. Throughout the day they text each other, taking advantage of brief lulls when Cuzella can pop into an exam room to check for gum disease or demonstrate good brushing habits. Braun herself takes similar opportunities to assess oral health during her exams, and both focus on educating parents.

Medical and dental care have traditionally been siloed. "Schools are getting better at interprofessional collaboration and education, but by and large we train separately, we practice separately," said Katy Battani, a registered dental hygienist and assistant professor at Georgetown University.

Battani is trying to bridge the divide by helping community health centers in nine states — including California, Texas, and Maryland — integrate dental care into prenatal visits for pregnant women. Pregnancy creates opportunities to improve oral health because some women gain dental coverage with Medicaid and see providers at least once a month, Battani said.

In Denver, housing instability, language barriers, lack of transportation, and the "astronomical cost" of dentistry without insurance make dental care inaccessible for many children, the migrant community, and seniors, said Sung Cho, a dentist who oversees the dental program at STRIDE Community Health Center, serving the Denver metro area.

STRIDE tries to overcome these barriers by offering interpretation services and a sliding pay scale for those without insurance. That includes people like Celinda Ochoa, 35, of Wheat Ridge, who waited at STRIDE Community Health Center while her 15-year-old son, Alexander, had his teeth cleaned. He was flagged for dental care during a past medical checkup and now he and his three siblings regularly see a dentist and hygienist at STRIDE.

One of Ochoa's children has Medicaid dental coverage, but her three others are uninsured, and they couldn't otherwise afford dental care, said Ochoa. STRIDE offers an exam, X-rays, and cleaning for $60 for the uninsured.

In the past year, Cho has seen an influx of migrants and refugees who have never seen a dentist before and need extensive care. Medical exams for refugees at STRIDE increased to 1,700 in 2023 from 1,300 in 2022, said Ryn Moravec, STRIDE's director of development. She estimates the program has seen 800 to 1,000 new immigrants in 2024.

Even with growing needs, Cho said the Medicaid "unwinding" — the process underway to reexamine post-pandemic eligibility for the government program that provides health coverage for people with low incomes and disabilities — has created financial uncertainty. He said he worries about meeting the upfront costs of new staff and of replacing aging dental equipment. 

At STRIDE's Wheat Ridge clinic, two hygienists float between dental and pediatrics as part of the medical-dental integration. Yet Cho said he needs more hygienists at other locations to keep up with demand. The pandemic created bottlenecks of need that are only now being slowly cleared, particularly because few dentists take Medicaid. If they do accept it, they often limit the number of Medicaid patients they'll take, said Moravec. Ideally, STRIDE could hire two hygienists and three dental assistants, Moravec said.

In 2022, Colorado enacted a law to alleviate workforce shortages by allowing dental therapists — midlevel providers who do preventive and restorative care — to practice. But Colorado does not have any schools to train or accredit them. 

Before age 3, children are scheduled to see a pediatrician for 12 well visits, a metric that medical and dental integration capitalizes on, particularly for at-risk children. As part of Braun's program in the Rocky Mountain region, providers have applied more than 17,000 fluoride varnishes and increased the percentage of children 3 and younger who received preventive oral health care to 78% from 33% in its first 2½ years.

Callaghan, at the Montana Primary Care Association, witnesses that on the ground at community health centers in Montana. "It's about leveraging the fact that kids see their medical provider for a well-child visit much more often and before they see their dental provider — if they have one."
