Orthodontic Services for Every Stage of Life
Braces: Classic and Comfortable for Every Smile
When you choose customizable metal braces, you’re choosing proven results combined with modern comfort and style. Patients of all ages love choosing the color of their braces at each appointment! We even offer gold braces for that extra shine.
No matter your age or orthodontic needs, we personalize every treatment to help kids, teens, and adults achieve confident, healthy smiles.
Invisalign: The Virtually Invisible Treatment Option
Invisalign offers a discreet way to straighten teeth without the look or feel of traditional braces, making them ideal for kids, teens, and adults alike.
These clear aligners are custom-made for comfort, flexibility, and real results, fitting your lifestyle as easily as they fit your smile.
Early Treatment: Give Your Child’s Smile a Head Start
Early orthodontic evaluations help us identify and address potential concerns before they become bigger issues. By beginning treatment at the right time (around age 7), we can guide jaw development, improve bite alignment, and create space for incoming teeth—setting your child up for a healthier smile.
Retainers: Keep Your Smile for Life
We offer high-quality retainers, including in-house retainers, to help protect your results for years to come. Retainers are crucial to maintaining your spectacular smile long after your braces or Invisalign treatment has been completed.
Plus, with our Lifetime Retainer Program, you can assure that your smile stays straight—for life.
Emergency Treatment: Here When You Need Us
Sometimes, the unexpected happens during orthodontic treatment. While many problems can be resolved at home with simple solutions, you may not be able to fix the issue by yourself. If that happens, contact us as soon as possible so we can help resolve your problem.
100% Smile Satisfaction Guarantee
At Greeley & Nista, we stand behind your smile for life. Our exclusive Guarantee My Smile program offers ongoing peace of mind by providing support and solutions if your teeth shift after treatment. Offering care that extends well beyond your final appointment is just one more way we go above and beyond at every step.
