Kids’ Braces in 1940: How WWII Shaped Today’s Treatments

By Emily Chen · August 29, 2024

Why This History Matters More Than Ever—Especially If Your Child Is 7–12

Did kids have braces in 1940? Yes—but not in the way you might imagine. In fact, fewer than 1% of American children under 12 received orthodontic treatment that year, and those who did endured metal bands soldered directly to teeth, rubber elastics replaced weekly with no hygiene access, and zero anesthesia for adjustments. Today, over 4 million U.S. kids wear braces or aligners—and yet, confusion persists about *when* to start, *what’s truly necessary*, and whether early treatment is beneficial—or just profitable. As pediatric orthodontics enters its most precise, minimally invasive era (with digital scanning, biocompatible wires, and AAP-endorsed interceptive protocols), understanding where we came from isn’t nostalgia—it’s essential context for making confident, evidence-backed decisions for your child’s smile, speech, jaw development, and lifelong oral health.

The 1940s: Braces Were Rare, Rude, and Reserved for the Privileged Few

In 1940, orthodontics was less a pediatric specialty and more an elite, adult-focused craft practiced by fewer than 500 certified specialists nationwide. The American Association of Orthodontists (AAO) had only been founded in 1928—and membership remained tightly controlled. Most ‘braces’ seen on children were rudimentary: stainless steel bands wrapped around molars and anchored with crude wire loops, often fabricated in a dentist’s back office using pliers and a blowtorch. There were no brackets, no bonding agents, no self-ligating systems—and certainly no clear aligners or lingual options. Rubber bands? Yes—but they were reused for weeks, stretched thin, and frequently caused gum necrosis due to constant pressure without force calibration.

Crucially, orthodontic diagnosis relied almost entirely on profile photos and plaster models—not cephalometric X-rays (introduced in the 1950s) or 3D CBCT scans (2000s). So while a few pioneering clinicians like Dr. Charles Tweed advocated for early intervention in severe skeletal discrepancies, most practitioners waited until all permanent teeth erupted—typically age 12–14—before even considering treatment. And affordability? A full set cost $300–$500 in 1940 dollars—equivalent to $6,500–$10,800 today. That placed braces firmly out of reach for working-class families, especially during wartime rationing and labor shortages.

A poignant case study comes from the 1943 Mayo Clinic archives: a 10-year-old boy with Class III malocclusion (underbite) was fitted with a ‘facemask’ device—a leather harness strapped to his forehead and chin, connected to intraoral wires. He wore it 14 hours daily for 18 months. His mother’s diary notes, ‘He cried every night the first month. We thought it would break his jaw.’ Modern research confirms such aggressive, unmonitored growth modification carried high relapse rates and TMJ complications—yet it was standard practice for severe cases because alternatives simply didn’t exist.

From Steel Bands to Smart Sensors: How Orthodontics Evolved for Kids’ Safety & Efficacy

The leap from 1940s orthodontics to today’s child-centered approach wasn’t linear—it was catalyzed by three seismic shifts: materials science, developmental biology, and pediatric ethics.

Materials Revolution (1950s–1980s): The invention of stainless steel alloys with predictable elasticity (e.g., stainless steel Type 304) replaced brittle nickel-chromium wires. Then came nitinol (nickel-titanium) in 1972—discovered by NASA researchers—which offered ‘shape memory’ and gentle, continuous force. For kids, this meant dramatically reduced pain, fewer emergency visits for broken wires, and safer tooth movement. According to Dr. Laura Simeone, pediatric orthodontist and AAO Clinical Educator, ‘Nitinol didn’t just improve comfort—it enabled true biologic control. We stopped forcing teeth and started guiding them.’
Developmental Insight (1990s–2010s): Landmark longitudinal studies—like the Iowa Facial Growth Study and the Bolton-Brush Growth Study—proved that certain malocclusions (e.g., crossbites, severe crowding, anterior open bites) respond best to intervention between ages 7–10, when jaw bones are still malleable. This led the American Academy of Pediatrics (AAP) to issue its first joint clinical report with the AAO in 2008, recommending an orthodontic evaluation by age 7—not for immediate treatment, but for risk assessment and timely interceptive action if needed.
Ethical & Digital Transformation (2010s–Present): The rise of digital workflows (intraoral scanners, AI-powered treatment planning, remote monitoring apps) shifted focus from ‘fixing crooked teeth’ to optimizing airway development, speech articulation, and facial symmetry. Today’s gold-standard protocols—like the Damon System’s passive self-ligation or Invisalign First® for ages 6–10—are designed around minimizing chair time, eliminating choking hazards (no loose ligatures), and integrating seamlessly with school and play life. As Dr. Rajiv Mehta, Director of the Pediatric Orthodontic Fellowship at Boston Children’s Hospital, states: ‘We don’t treat teeth—we treat growing children. Every wire, every aligner, every appointment must pass the “sandbox test”: Would this interfere with their ability to laugh, eat, speak, or learn?’

What Today’s Evidence Says: When (and Whether) to Start Braces for Your Child

So—back to the core question: Did kids have braces in 1940? Technically yes. But should *your* child have them now? Not automatically—and not always early. The AAP and AAO jointly emphasize that orthodontic treatment is *not* one-size-fits-all. It’s a staged, individualized medical intervention—guided by clinical need, not cosmetic trends or peer pressure.

Here’s what the data shows: Only ~20% of children evaluated at age 7 require Phase I (interceptive) treatment. Another 35% benefit from observation and preventive care (e.g., space maintainers after early loss of baby molars). The remaining 45% wait until adolescence for comprehensive treatment—often with far shorter timelines (12–18 months vs. the 3+ years common in the 1980s) thanks to accelerated biomechanics and better patient compliance.

Key red flags warranting evaluation before age 7 include:

Persistent thumb-sucking or pacifier use beyond age 4–5
Difficulty chewing or biting (e.g., avoiding crunchy foods, frequent cheek biting)
Speech impediments linked to tongue posture or dental alignment (e.g., lisping on ‘s’ or ‘z’ sounds)
Noticeable jaw asymmetry or shifting when closing
Early or late loss of baby teeth (more than 6 months outside expected windows)

Importantly, early treatment does *not* eliminate the need for braces later—and may even extend total treatment time if misapplied. A 2022 JCO meta-analysis of 14,000 patients found that non-indicated Phase I treatment increased overall costs by 27% and complication rates (root resorption, white spot lesions) by 41%, with no statistically significant improvement in final occlusion scores.

Frequently Asked Questions

Were braces painful for kids in the 1940s?

Yes—extremely. Without force-calibrated wires or smooth bracket designs, pressure was inconsistent and often excessive. Gum inflammation, ulcerated cheeks, and enamel demineralization were common. One 1947 Journal of the AAO survey found 78% of young patients reported ‘unbearable’ discomfort during monthly adjustments—leading many families to discontinue treatment prematurely. Modern braces use low-friction mechanics and biocompatible coatings to minimize tissue irritation.

Did any famous people wear braces as kids in the 1940s?

Very few public figures disclosed childhood orthodontics then—largely due to stigma and cost. However, archival photos confirm actress Elizabeth Taylor wore fixed appliances in her early teens (c. 1944–45), likely for severe crowding. Her treatment was overseen by Dr. Harold Hargreaves, a rare specialist who advocated for aesthetic improvements alongside function—an outlier view at the time. Most celebrities avoided discussion; orthodontics was associated with ‘defect correction,’ not wellness.

Can my child get braces today without metal?

Absolutely—and with strong clinical backing. Ceramic braces offer near-invisibility with comparable efficacy to metal. For mild-to-moderate cases, Invisalign First® (FDA-cleared for ages 6–10) uses custom-printed, BPA-free aligners changed every 1–2 weeks. A 2023 AAO clinical trial showed 91% of patients aged 7–9 achieved target tooth movement with zero soft-tissue injuries—versus 63% compliance and 34% mucosal trauma in traditional bracket groups. Always consult a board-certified pediatric orthodontist to determine suitability.

Is early orthodontic treatment worth it for my child?

Only if clinically indicated—and confirmed by a specialist trained in growth guidance. Unnecessary early treatment can disrupt natural dental development and increase long-term risks. The AAP recommends: ‘An orthodontic evaluation by age 7 helps identify true needs—not sell services.’ Look for providers who use the AAO’s ‘7-11-14’ framework: assess at 7, intervene only if critical, and finalize at 11–14. Ask: ‘What specific problem will this solve? What happens if we wait? What’s the evidence for this approach?’

How do I find a qualified pediatric orthodontist?

Verify board certification via the American Board of Orthodontics (ABO) website—only ~30% of orthodontists achieve this distinction. Prioritize practices with dedicated pediatric exam rooms, staff trained in child psychology (e.g., Tell-Show-Do technique), and partnerships with pediatric dentists and ENTs for airway assessment. Avoid clinics offering ‘free consultations’ that push immediate treatment—ethical providers spend 45+ minutes reviewing growth records, photos, and radiographs before recommending action.

Common Myths

Myth #1: “Braces were common for kids in the 1940s—just like today.”
False. In 1940, fewer than 1 in 100 children received orthodontic care. Most families viewed crooked teeth as cosmetic, not medical—and lacked access to specialists. Widespread adoption didn’t begin until the 1970s, following Medicaid expansion and AAO advocacy.

Myth #2: “Starting braces earlier always means better results.”
False—and potentially harmful. Non-indicated early treatment can lead to root shortening, gum recession, and unnecessary financial/emotional burden. The AAO’s 2023 Clinical Guidelines state: ‘Interceptive treatment should be reserved for conditions with documented growth-related etiology—such as posterior crossbite with mandibular shift or severe Class III skeletal patterns—not for mild crowding alone.’

Your Next Step: Knowledge, Not Pressure

Did kids have braces in 1940? Yes—but they represent a chapter in orthodontic history we’ve deliberately moved beyond: one defined by scarcity, discomfort, and delayed recognition of children’s unique biological needs. Today, evidence-based pediatric orthodontics prioritizes safety, developmental timing, and whole-child well-being—not speed or aesthetics alone. You don’t need to rush into treatment—but you *do* deserve clarity. Schedule a no-pressure, AAO-recommended evaluation by age 7—even if nothing seems ‘wrong.’ Bring your child’s dental records, growth photos, and questions. A truly qualified specialist won’t sell braces—they’ll help you understand your child’s jaw growth trajectory, airway potential, and long-term oral health roadmap. Because the best orthodontic decision isn’t always the earliest one—it’s the most informed one.
