Orthodontic Treatments and Services Made for You
We offer a full range of effective treatments to help patients of all ages achieve confident, healthy smiles. Our Wilmington team delivers expert guidance and personalized care at every step of your orthodontic journey.

Invisalign in Wilmington
Invisalign is a discreet method for straightening teeth using a series of clear aligners. The subtle nature of Invisalign benefits patients of all ages! As one of the top providers of Invisalign in the Mid-Atlantic area, we’re ready to help transform your smile with this revolutionary technology.

Braces in Wilmington
Braces are a tried-and-true method to get a straighter, healthier smile. Traditional braces are popular among our patients because they’re effective for kids, teens, and adults alike. We even offer 24k gold braces for those who want to add some flair to their treatment!

Early Treatment
Starting your child’s orthodontic care around age seven can lay the foundation for a lifetime of confident smiles! Our team offers expert evaluations to catch and correct issues before they become bigger problems. We can monitor your child’s smile if treatment isn’t needed yet, or we can provide tailored treatment to guide their growing smile.

Retainers
You deserve a smile that lasts a lifetime, and that’s where retainers come in! Once you finish braces or Invisalign treatment, you’ll wear a retainer to keep your smile in place. We even offer an exclusive Lifetime Retainer Program to help you maintain your stunning results.

Emergency Care
Orthodontic emergencies are rare, but issues like poking wires, loose brackets, or lost appliances can disrupt your treatment. To keep your progress on track, we’ll provide you with at-home solutions to these problems or schedule the earliest available appointment for you to be seen. Don’t hesitate to call us if you have a concern.
At Greeley & Nista Orthodontics, we understand that investing in the look and health of your smile is a lifetime commitment. Our Guarantee My Smile program ensures you can keep the smile you want at an affordable price, even if your teeth shift out of alignment long after you’ve finished orthodontic treatment.
