Welcome to Otter Orthodontics

Meet Dr. Gemma Hill: Your Orthodontic Partner

Dr. Gemma Hill brings a unique perspective to orthodontic care as Happy Valley's only female orthodontist and practice owner. Her journey to orthodontics began from personal experience, having been bullied for her dental issues as a child. After receiving life-changing orthodontic treatment herself, she was inspired to provide that same confidence-boosting care to others. With extensive education from institutions including the University of Michigan and Loma Linda University, plus specialized training in aligner therapy and orthodontic business management, Dr. Hill combines technical expertise with genuine empathy to help patients achieve their healthiest, most confident smiles.

Comfort, Care, and Thoughtful Touches at Every Visit

We’ve designed our office with your comfort in mind, creating a space that feels welcoming, calming, and family-friendly with thoughtful amenities to make every visit a little more enjoyable.

Freshly Baked Cookies and Refreshments
Our freshly baked cookies are a favorite among patients and families of all ages. We also offer a coffee bar, bottled water, and free Wi-Fi to help you feel right at home during your visit.

The Little Otter Cove
‍Our new "Little Otter Cove" features a lending library, art table, and photo booth to keep little ones engaged and entertained. Soon, we’ll be displaying patient artwork in custom frames as part of our rotating gallery wall.

Specialty Products and Patient Kits
We carry a hand-picked selection of products, including Coco Floss, the Synapse Dental Pain Eraser, and EverSmile Aligner and Retainer Cleaner. We also provide emergency comfort kits for our braces patients — perfect for managing small issues between visits.

Upgraded Technology for Comfort
Our new iTero Lumina scanner features a smaller scan tip and improved imaging for a faster, more comfortable digital scan experience.

Comfort Menu and Sensory Support
For patients who experience anxiety or sensory challenges, we offer a Comfort Menu with a range of supportive options. This includes weighted blankets, noise-canceling headphones, fidget toys, poppers, sunglasses, and a “pause card” so patients can let us know discreetly if they need a short break. We’re also happy to provide treatment in a semi-private bay upon request.

Comprehensive Orthodontic Solutions for All Ages

Otter Orthodontics specializes in creating beautiful, functional smiles for patients of all ages using the latest techniques and technologies. Our services include traditional metal and sleek gold braces, Invisalign clear aligners (including Invisalign First for young children and Invisalign Teen), early interceptive orthodontics, and collaborative surgical orthodontics. We excel at identifying and addressing orthodontic issues early through our Kids Club program, which ensures children receive timely evaluations at age 7. Dr. Hill works closely with oral surgeons when needed for specialized procedures like exposing impacted canines or maxillary skeletal expansion (MSE). Whatever your orthodontic needs, we provide personalized care and multiple treatment options.
