Adult & Pediatric Orthodontics provides braces and Invisalign treatment for patients of all ages in Portland and Windham, Maine.

About Adult & Pediatric Orthodontics
Invisalign and clear aligner cases, plus expanders for younger kids, make up much of the work here, with the orthodontist handling even complex surgical cases across two office locations.
The orthodontist is often mentioned for taking on complicated cases, including combining Invisalign with jaw surgery for an underbite, and for remembering patients years after treatment ends. Reviews frequently note straight, well-aligned results, from Invisalign smiles to braces-and-expander outcomes for children. The practice runs two locations, which several families mention as a convenience, and staff are noted for keeping young kids engaged during expander fittings and other procedures that can otherwise cause anxiety.

Doctor Yu is fantastic, and everyone who runs the office is incredibly kind and easy to work with.
I couldn’t be happier with the service we Adult & Pediatric Orthodontics! Everybody was always incredibly friendly and helpful throughout the whole process for my daughters Invisalign. If I had to go through the process all over again, I would definitely choose them and will do so for my kids that need orthodontic work in the future.
This practice is amazing! They made Invisalign 100% affordable. Not to mention, the around the clock care you get. It’s VIP service. I thank Dr. Yu and her entire team, for helping make this experience easy for my daughter, and I.
I LOVE Adult + Pediactric orthodontics!! I came in with teeth that were all over the place (lol) but Dr. Yu is SOOOO smart and she was able to make them straight! The staff is really kind too, they treated me and my family really well. 1000/10 would totally recommend! Also here’s proof of my teeth transformation:
Dr Yu and her entire team are wonderful. They are professional, knowledgable, personal, kind and have a sense of humor. Two of my kids were patients and I was a patient. Highly recommend Dr Yu.
