Kansas ranks as the best state for children's oral health in 2026 and New Jersey ranks as the worst, according to a WalletHub analysis reported by Becker's Dental Review in April 2026. The study compared all 50 states and Washington, DC across 10 pediatric oral health metrics, including the share of children with excellent or very good teeth, the share with a recent dental checkup, and dental treatment costs. Where your family lives clearly shapes the odds your child sees a dentist and avoids cavities, but the ranking is a starting point, not a verdict, because habits at home and a steady dental home matter just as much as geography.
What are the key numbers parents should know?
The headline figures come from a personal finance study and two national health sources, and each one below is tied to a named source and year.
- 10 metrics compared across 51 places.

- Kansas first, New Jersey last. Kansas topped the children's oral health list while New Jersey landed at the bottom, and the District of Columbia slid from first place in 2025 to seventh in 2026. (Source: Becker's Dental Review and WalletHub, 2026)
- More than half of young children already have a cavity. More than half of children aged 6 to 8 years have had a cavity in at least one baby tooth, and tooth decay remains the most common chronic disease of childhood in the United States. (Source: Centers for Disease Control and Prevention, 2026)
Which states rank best and worst for children's oral health in 2026?
Kansas, Minnesota, and New Mexico lead the 2026 list, while New Jersey, Utah, and Mississippi sit at the bottom. The table below shows the top 10 and bottom 10 states for children's oral health as reported by Becker's Dental Review, drawn from the WalletHub data.
| Rank | Top 10 states for kids' oral health | Bottom 10 states for kids' oral health |
|---|---|---|
| 1 | Kansas | New Jersey |
| 2 | Minnesota | Utah |
| 3 | New Mexico | Mississippi |
| 4 | Michigan | Oklahoma |
| 5 | Iowa | Florida |
| 6 | Illinois | North Carolina |
| 7 | District of Columbia | Massachusetts |
| 8 | Wisconsin | Idaho |
| 9 | Vermont | Maine |
| 10 | North Dakota | Delaware |
The bottom column is ranked from most concerning, so New Jersey scored worst overall on the pediatric measures. Families in a top state should not assume their own child is covered, and families in a bottom state are far from powerless, as the sections below explain.
What did WalletHub measure to rank children's oral health?
WalletHub built the ranking from 10 pediatric oral health metrics rather than a single number, so the list rewards states that combine healthy children with real access to care. Reported metrics included the share of children aged 1 to 17 with excellent or very good teeth, the share with a recent dental checkup, and the cost of dental treatment, alongside supporting measures such as fluoridated water access, school based dental sealant programs, free or low cost clinics per person, and dentist participation in Medicaid. Because the score blends outcomes with access and cost, a state can slip if care is simply too expensive or too far away, even when its dentists are excellent.
WalletHub cited public data from sources including the U.S. Census Bureau, the Centers for Disease Control and Prevention, the American Dental Association, and the Child and Adolescent Health Measurement Initiative. That mix is why the ranking is more useful to parents than a single satisfaction survey: it reflects both how children's teeth are actually doing and how hard it is for a family to get seen.
Why does a strong overall child health state still rank low for kids' teeth?
Because oral health and general pediatric care do not always move together, a state can excel at one and lag at the other. In a separate WalletHub report on children's health care released in April 2026, Massachusetts ranked as the best state overall for children's health care with a score near 64, while Texas ranked worst with a score near 33. Yet Massachusetts appears in the bottom 10 for children's oral health specifically, a reminder that strong pediatricians and insurance coverage do not automatically translate into strong dental access.
"The quality of children's health care should be one of the most important considerations for parents when deciding where to live," said Chip Lupo, a WalletHub analyst, in the company's 2026 children's health care report.
For parents, the practical lesson is to treat dental care as its own line item. A family relocating for good schools or good hospitals should still check whether local pediatric dentists are accepting new patients and whether their insurance is accepted before assuming the move is a win for their child's smile.
What does this ranking mean for your family, wherever you live?
The ranking should guide action, not anxiety, because the single most protective step is the same in every state: establish a dental home and keep regular visits. The American Academy of Pediatric Dentistry and the American Dental Association recommend a first dental visit by a child's first birthday and checkups roughly every six months after that. A steady relationship with one practice means fluoride varnish, sealants, and early cavity spotting happen on schedule rather than during a painful emergency.
If you live in a top ranked state such as Illinois, the infrastructure is on your side, and finding an in network pediatric practice like Bauer Dentistry and Orthodontics in Wheaton is usually the main task. If you live in a lower ranked state such as Texas, access takes more planning, and locating a dedicated children's office like Hurst Pediatric Dentistry early can prevent long waits later. Either way, the browsing tools on Smile Listing let you compare verified clinics, services, and reviews before you book.
A few steps carry the most weight for parents no matter where a state ranks:
- Book a checkup before the school year, and pair it with your child's back to school routine. Our guide to back to school dental checkups in 2026 explains why this visit matters more this year.
- Confirm your dentist participates in your plan, especially if you rely on Medicaid or CHIP, since coverage and provider participation are shifting in 2026. See our coverage of proposed Medicaid dental cuts for context.
- Ask about fluoride varnish and sealants at each visit, two of the most cost effective ways to prevent decay in children.
- Brush twice a day with a fluoride toothpaste and limit sugary drinks between meals, the daily habits that outrank any state score.
How reliable is a personal finance ranking of children's teeth?
A ranking like this is a useful snapshot, not a diagnosis, and it should be read with its limits in mind. WalletHub is a personal finance company, and its scores compress complex health data into a single order, which can hide wide variation inside a state. A rural county in a top ranked state may have fewer dentists than a well served city in a bottom ranked state. The value of the list is that it flags where access and outcomes tend to be weakest so families and policymakers know where to push, not that it predicts any one child's experience. For the underlying methodology and full state list, parents can review the WalletHub children's health care report directly.
Frequently asked questions
What is the best state for children's oral health in 2026?
Kansas ranked first for children's oral health in the 2026 WalletHub analysis reported by Becker's Dental Review, followed by Minnesota and New Mexico.
What is the worst state for children's oral health in 2026?
New Jersey ranked last, with Utah and Mississippi also near the bottom of the 2026 list of 50 states and Washington, DC.
How does WalletHub decide these rankings?
WalletHub scored states on 10 pediatric oral health metrics, including the share of children with excellent or very good teeth, recent dental checkups, dental treatment costs, fluoridated water access, and dentist participation in Medicaid, using public data from the CDC, the Census Bureau, and the American Dental Association.
My state ranks low. Does that mean my child will have bad teeth?
No. A low state ranking reflects average access and outcomes, not your child's fate. Keeping regular checkups, using fluoride toothpaste, applying sealants, and limiting sugary drinks matter more for any individual child than the state score.
When should my child first see a dentist?
The American Academy of Pediatric Dentistry and the American Dental Association recommend a first dental visit by age one, followed by checkups about every six months.
