Information you can trust for a smile you’ll love.

It’s no secret that clear aligners are rising in popularity as an alternative to metal braces. And for good reason -- clear aligner treatment presents a number of undeniable benefits that patients love.

But the truth is, the goal of all those sponsored ads you’ve been seeing as you scroll down your feeds (the ones for aligners delivered straight to your doorstep, without ever having to visit an orthodontist’s office) is to market a product. 

But we’re doing things differently at 425 Clear Aligners. After years of talking with patients and providing clear aligner treatment, Dr. Rooz has learned that people are eager to find gimmick-free resources that provide straightforward, trustworthy, and accessible information. 

We’re here to educate, to inform, and to ensure that your decision about orthodontic treatment is based on scientific, evidence-based information -- not marketing tactics. 

Meanwhile, Dr. Rooz is providing convenient and comfortable orthodontic care at his Sammamish clinic, Porth. If you are ready to come in for a consultation, or have any questions, please visit Porth’s website to get started.
