When most people hear the word “orthodontist,” they immediately think of braces, and for good reason. Orthodontists are the specialists who help people achieve straighter teeth, fix bad bites, and improve overall oral health. But if you’ve ever wondered: What do orthodontists do exactly? You’re not alone.
Orthodontics is about much more than just straight smiles. It’s a field that combines science, technology, and healthcare to guide the development of teeth, jaws, and facial structure. Whether you’re considering braces, Invisalign®, or just want to understand the role of an orthodontist better, this guide will walk you through everything you need to know.
What Is an Orthodontist, and What Do They Do?
An orthodontist is a dental specialist who focuses on correcting teeth and jaw irregularities. While all orthodontists are dentists, not all dentists are orthodontists. After dental school, orthodontists complete two to three years of specialized training in tooth movement, bite alignment, and facial growth.
So, what does this mean in practice? Orthodontists diagnose and treat dental issues such as overbites, underbites, crooked teeth, crowding, gaps, and misaligned jaws. Braces, clear aligners like Invisalign®, retainers, and other appliances gradually move your teeth into a healthier, more functional, and better-looking position.
This isn’t just cosmetic. Misaligned teeth can make it difficult to chew, speak clearly, or keep your mouth clean. Left untreated, bite issues can lead to problems like gum disease, tooth decay, and even headaches or jaw pain. That’s why orthodontic care is about more than appearances; it’s about long-term oral health and overall well-being.
How Is an Orthodontist Different from a Dentist?
Dentists and orthodontists care for oral health, but their focus and training differ. A general dentist handles everyday dental needs: cleanings, cavities, fillings, crowns, gum health, and general checkups. They’re the go-to provider for maintaining a healthy mouth.
Orthodontists, on the other hand, are specialists. They don’t fill cavities or treat gum disease; they step in when your teeth or jaws aren’t aligned properly. You might see an orthodontist if:
- You have crowded or crooked teeth
- You’re having trouble with your bite
- You want to explore treatment like braces or Invisalign
- Your child is showing early signs of jaw misalignment
Consider it like this: if dentistry is general healthcare for your mouth, orthodontics is like physical therapy for your smile. It focuses on movement, alignment, and guiding your teeth into their ideal positions for long-term function and aesthetics.
What Treatments Do Orthodontists Offer?
Now that you understand what an orthodontist is and what they do, let’s look at some treatments they provide. The most common are braces, but modern orthodontics offers much more than just metal brackets and wires.
1. Braces (Traditional and Clear)
Braces remain one of the most effective ways to treat misaligned teeth. Orthodontists use them to apply gentle, constant pressure that slowly moves your teeth into place. Today’s options include metal, ceramic, and even clear brackets that blend in with your smile.
2. Invisalign® and Clear Aligners
For teens and adults who prefer a more discreet option, Invisalign and other clear aligners offer a nearly invisible way to straighten teeth. These removable trays are custom-made and replaced every few weeks as your smile improves.
3. Retainers
After braces or aligners, orthodontists use retainers to keep teeth from shifting back into their old positions. Retainers may be fixed or removable; wearing them is essential for long-term success.
4. Space Maintainers and Palatal Expanders
For younger patients, orthodontists may use appliances that guide jaw development or hold space for future permanent teeth. These early interventions can reduce the need for more complex treatment later on.
5. TMJ and Jaw Alignment Treatment
Some orthodontists also help with jaw pain or TMJ (temporomandibular joint) issues caused by misalignment. They can create customized appliances to help relieve pressure and improve jaw function.
At Mellion Orthodontics, we take a personalized approach to treatment, choosing the right method for each patient’s unique smile, age, and lifestyle.
When Should You See an Orthodontist?
You don’t have to wait until something is “wrong” to visit an orthodontist. The American Association of Orthodontists recommends that children have their first check-up by age 7. Early evaluation doesn’t always lead to treatment, but it allows the orthodontist to spot and monitor issues early.
During these visits, orthodontists may also use diagnostic imaging to evaluate teeth and jaw development. If you’re curious about how frequently imaging is recommended, you can read our guide on how often you need dental X-rays to learn more.
That said, orthodontic care isn’t just for kids. Many teens and adults seek treatment to improve their bite or enhance their smile. Thanks to technological advancements, adults can now access discreet, comfortable options like Invisalign and clear ceramic braces.
You should consider seeing an orthodontist if:
- Your teeth are crooked, crowded, or spaced apart
- Your bite feels off (underbite, overbite, or crossbite)
- You have jaw pain or discomfort
- You’re unhappy with your smile’s appearance
- Your child has a thumb-sucking habit or jaw alignment issue
The sooner you address alignment problems, the easier and more effective treatment can be. No matter your age, improving your smile is never too late.
