Your Smile is Our Top Priority

You may have a lot of orthodontic options in Portland and Windham, but see why it’s obvious your family will be at home with Dr. Yu at Adult & Pediatric Orthodontics.

Expert Training

Dr. Joanna Yu is an orthodontist. Orthodontists are dentists first. Out of 100 dental school graduates, on average, only six go on to become orthodontists.

To practice orthodontics, Dr. Yu spent 11 years in training (four years of college, four years of dental school, and three years of orthodontics residency).

The orthodontic student spends three years learning the skills needed to manage tooth movement and to guide facial development.

You want an expert to give you a new smile—not from aligners you get in the mail.

New Patients

Personal Approach

We recognize that every patient has different needs, and we pride ourselves in providing individual care and personalized treatment plans to every member of your family.

Whether you’re an adult, teen or child, Dr. Yu and our team are committed to helping you achieve the healthy, beautiful smile you deserve!

From the moment you contact our office to your final retainer check appointment, our goal at Adult & Pediatric Orthodontics is your complete satisfaction. Dr. Yu will review your photos and X-rays to find the best way to treat your individual needs.

Then you’ll choose the type of braces you want - traditional metal, clear ceramic, or Invisalign. Our goal at Adult & Pediatric Orthodontics is not just to give you the smile of your dreams.

We want you to leave our office after every appointment knowing that you got the best possible care.

Windham Orthodontics

Comfortable Treatments

Gone are the days of painful headgear, clunky bands on every tooth, and overly tight stainless steel wires. Today's orthodontic treatment is much more comfortable than it used to be. This is because we use the most up-to-date technologies available.

At Adult & Pediatric Orthodontics, we use Damon braces, the very first self-ligating bracket system. Damon braces use lightweight wires and lower friction brackets, resulting in fewer adjustment appointments, less discomfort, and faster treatment.

At Adult & Pediatric Orthodontics, we take pride in making the process of straightening your teeth as comfortable as possible.

Modern Techniques

For more than 15 years, Dr. Yu has been creating smiles in the Portland and Windham communities. Every patient has different needs and Dr. Yu and her staff use the latest technologies and treatments to meet every patient’s unique needs to ensure the best results and beautiful smiles.

Dr. Yu is up-to-date on the latest in orthodontic treatment and braces technology. Adult & Pediatric Orthodontics is your location in Portland and Windham for modern orthodontic treatment.

We offer aesthetic options like Damon braces and Invisalign for faster and more efficient tooth movement and faster treatment times.


Start Your Treatment the Same Day

The orthodontic treatment process involves a series of orthodontic visits.

We value the relationship that we will build with you and your family throughout that process and want you to be confident that you are receiving the best orthodontic care possible.

Once you feel like we've answered all of your questions and concerns, you can start your treatment that same day.

We value your time, and we know you want to make the most of your visit.

Affordable Smiles

We believe that braces shouldn’t break the bank. With our flexible pricing options, we provide personalized payment plans that will work for you and your family’s budget.

After we’ve determined your insurance coverage and filed it for you, we'll sit down and come up with a monthly payment plan that fits your family’s budget. You can also get a discount if you pay in full on the front end.


Convenient Locations

We have two high-tech and cozy offices to serve our community better. Our Portland Office is positioned right in the heart of the city, surrounded by a variety of shopping and dining options.

Our Windham office is conveniently located to fit into your busy schedule. That means great orthodontic care is only a few minutes from your home, work, or school.


We know braces can be a lot of hard work. As a way to show our appreciation for your efforts, we give out Orthopoints at every appointment.

These points can be redeemed at any point during your treatment for gift cards to some of our favorite places like Bull Moose and Olympia Sports.

On-time for your appointment? That's one Orthopoint! Did you visit your dentist in the last six months? That's five Orthopoints!
