Orthodontics has changed a lot in the last few decades. What used to be considered standard care in the 1990s is no longer the way modern orthodontists think about tooth movement, jaw development, or long-term stability. But some of those old ideas have stuck around in the way parents talk about braces, and they still shape decisions today.
At Santucci Orthodontics, we hear the same myths come up almost every week. Some are harmless. Others lead families to delay treatment, push for unnecessary tooth extraction, or dismiss real orthodontic problems as things a child will simply grow out of.
Here are five of the most common orthodontic myths parents still believe, and what’s actually true.
Myth 1: Kids Grow Out of Grinding
Bruxism, or tooth grinding, is often written off as a childhood phase. Parents hear it at night, mention it at the pediatrician’s office, and are frequently told not to worry because their child will outgrow it.
The truth is more complicated. Grinding in children is rarely random. It’s often the body’s response to something else going on, most commonly a bite that isn’t aligned properly or an airway that isn’t functioning the way it should. Kids who grind their teeth at night are frequently kids whose jaws haven’t developed in a way that allows for comfortable rest. The grinding is a symptom, not the problem.
Left unaddressed, grinding can wear down tooth enamel, contribute to jaw pain, and disrupt sleep quality. And while some children do stop grinding as they get older, many carry the pattern into adulthood.
If your child grinds their teeth, it’s worth getting an orthodontic evaluation. In many cases, the underlying cause is treatable, and once it’s addressed, the grinding tends to resolve on its own. Airway function and jaw development are often part of that picture.
Myth 2: Wisdom Teeth Cause Crowding
This is one of the most persistent orthodontic myths, and it’s one that even some dentists still repeat. The story goes like this: after braces, wisdom teeth erupt in the back of the mouth and push everything forward, which is why the front teeth shift out of alignment.
Decades of orthodontic research have shown this isn’t accurate. Wisdom teeth do not exert enough force on the rest of the arch to cause meaningful movement of the front teeth. The lower incisors tend to crowd and shift over time in almost everyone, including people who never had wisdom teeth at all and people who had them removed as teenagers.
The real reason teeth shift after orthodontic treatment is much simpler: teeth are living structures that respond to force and biology throughout life. The forces of the tongue, lips, cheeks, and bite continue to influence tooth position long after braces come off. That’s why lifelong retainer wear is the actual answer to preventing shifting, not wisdom tooth extraction.
Wisdom teeth may still need to be removed for other reasons, like impaction, infection risk, or difficulty cleaning them. But preventing crowding isn’t one of them.
Myth 3: Braces Are Just for Straightening Teeth
Ask most people what braces do, and they’ll say something about straightening crooked teeth. That’s true, but it’s an incomplete picture of what orthodontic treatment actually accomplishes.
Modern orthodontics addresses tooth alignment, bite function, jaw development, facial harmony, and airway health. Straight teeth are one outcome. A properly functioning bite, balanced facial proportions, and a healthy airway are equally important, and in many cases, they matter more for long-term health than pure esthetics.
For example, a child with a narrow palate might have relatively straight front teeth but a bite that’s contributing to poor sleep, mouth breathing, or crowding that will worsen as adult teeth come in. Treating only the visible crookedness without addressing the underlying structure would miss the actual problem.
This is why an orthodontic evaluation looks at far more than whether teeth appear crooked. The approach at Santucci Orthodontics treats crowding and misalignment as signs of something happening in the mouth as a whole, not as isolated problems to fix in isolation.
Myth 4: Adults Are Too Old for Orthodontic Treatment
There’s a common belief that orthodontic treatment is really for children and teens, and that once someone reaches adulthood, the window has closed. Adults who consider braces sometimes hesitate because they think they’ve missed their chance, or that treatment won’t work as well on fully developed teeth and jaws.
None of that is true. Teeth can be moved orthodontically at any age. The biology that allows tooth movement, the periodontal ligament and surrounding bone, continues to function throughout life. Adult orthodontic treatment is more common than ever, and modern options have made it far more discreet and comfortable than the metal braces of decades past.
Clear aligners, ceramic braces, and lingual braces (which attach to the back of the teeth) give adults options that fit into professional and social lives without the visibility of traditional metal braces. Treatment plans for adults are typically designed with the same precision and comfort priorities as treatment for younger patients.
The differences between adult and adolescent orthodontics are mostly about growth. Children and teens are still developing, which means their jaws can be guided during treatment. Adults have completed skeletal growth, so some treatments that rely on jaw expansion require different approaches. But the fundamental ability to align teeth, correct bites, and improve smile esthetics is fully available in adulthood.
Adult orthodontic treatment has become a significant part of what we do, and patients often tell us they wish they had started sooner.
Myth 5: You Only Need to See an Orthodontist Once Your Child Has All Their Permanent Teeth
Many parents assume that orthodontic evaluation should wait until all the baby teeth have fallen out and the permanent teeth are fully in. It sounds logical. Why check for tooth alignment before the teeth that need to align are even in the mouth?
The reason is that orthodontists evaluate more than just the position of teeth. During childhood, the jaws are still developing. Palate width, bite relationships, jaw growth patterns, and the position of erupting teeth can all be assessed early enough to make a real difference. Some orthodontic issues are much easier to address while a child is still growing than after all the permanent teeth are in and growth has slowed.
The American Association of Orthodontists recommends that every child receive an orthodontic evaluation by age seven. For most children, this evaluation is simply reassurance that everything is developing well. For a smaller group, it identifies something that benefits from early attention while the mouth is still highly responsive to guided change.
Waiting until every permanent tooth has erupted often means missing the window when early orthodontic intervention would have been simpler, shorter, and more effective. That doesn’t mean every seven-year-old needs braces. It means that seven is when we can first see clearly what’s developing, and act if action is warranted.
