What Our Patients Have Told Us

Dr. Rooz and his staff are knowledgeable and willing to answer all of your questions before, during, and after treatment. Dr. Rooz's expertise with new technologies and treatments, paired with clear explanations of the process, makes the experience more comfortable. I especially appreciate the kindness and patience given when working with patients (I wanted to change my billing option and Elly assisted me right away). Thank you!

Dr. Rooz and his team are the best! After doing traditional braces over 10 years ago and forgetting to wear my retainer I was nervous to do the orthodontist experience again. His office is clean, bright and full of energy!
He walked me through the entire process and answered all of my questions. I extremely appreciate their flexible payment plans and their willingness to go above and beyond for their clients.
Being able to text the office to schedule appointments or ask questions regarding my treatment, makes this process so much easier for me.
If you have ever been interested in clear aligners, schedule an appointment with Dr. Rooz. I’m so happy with my smile and my experience has been amazing!

Alexis N.

My experience was excellent! They corrected my bites and my teeth moved significantly within a year! They are very professional and nice -- they explain every step and set the right expectations with you before you start your treatment so you won't get any surprises. They made me feel like I was family & or a friend, rather than a patient. I began my treatment at their Sammamish location and I am so glad they made the decision to open one in Bellevue. It will be much closer to my location and save a lot of time on commute! I highly recommend them if you are looking for a talented and highly skilled orthodontist with advanced orthodontic techniques! Go and check out them 🙂

New Smile with Clear Aligners

Achieving a new smile through tooth alignment has been revolutionized by the advent of clear aligner technology, such as Invisalign clear aligners, SureSmile aligners, Angel Aligners, Spark, uLab Aligners, ClearCorrect and more.

These systems use a series of custom-made, thermoplastic aligners, crafted using plastic materials like SmartTrack or Quartz. Unlike traditional methods that rely on metal brackets, this clear aligner system is partially invisible with likely better oral health and periodontal care by allowing easier cleaning and maintenance. It is important to mention that clear aligners could be worse than braces if they are not removed regularly and the oral hygiene doesn't maintained well.

The ortho treatment involves receiving a new set of aligners, typically every week, which gently shift teeth into the desired position. The process is mapped out from the start using a digital scanning (iTero or 3shape), illustrating how Invisalign work to correct various dental issues. The Invisalign system and similar options like ClearCorrect provide clear, step-by-step guidance on tooth alignment. Accessibility to cutting edge technology has change aligner treatment.

The total treatment cost varies, with many providers offering a monthly payment plan to help manage healthcare expenses. How it works: patients wear each set of plastic aligners for the recommended period, usually 20 to 22 hours a day, advancing to a new set as their teeth alignment improves, leading to a healthier, more attractive smile typically within 6 to 18 months.

Clear aligners aka Invisalign is a great choice for the right patient of all ages - kids, teens and adults.

Treatments for Sleep Breathing Disorders (including airway obstruction)


Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) is a disorder characterized by repeated episodes of partial or complete obstruction of the upper airway during sleep, leading to breathing pauses. These pauses in breathing, known as apneas, can lead to reduced oxygen levels in the blood and result in brief awakenings throughout the night, although individuals often do not remember these awakenings. The cycle of disrupted breathing and arousal from sleep can occur multiple times an hour and impairs the ability to achieve deep, restorative sleep, causing excessive daytime sleepiness and fatigue.


Symptoms of OSA may include loud snoring, witnessed pauses in breathing during sleep, tossing and turning, waking up with a dry or sore throat, headaches upon waking, and excessive daytime sleepiness.

Orthodontic Treatment for Sleep Apnea

Specific orthodontic treatments can assist in managing obstructive sleep apnea (OSA). Our clinic works in conjunction with various sleep medicine specialists to provide accurate diagnoses of OSA.


Dr. Rooz offers a range of treatment options to aid patients diagnosed with this condition. These treatments include jaw surgery and the use of oral appliances. Additionally, we provide orthodontic care for patients who encounter complications related to their sleep oral appliances.

Orthodontist Treating Airway Disorders

Dental providers and orthodontists with an interest in sleep dental medicine often pursue additional training to provide treatments for sleep-related breathing disorders (SBD).


Dr. Rooz is a dentist qualified by the American Academy of Dental Sleep Medicine (AADSM), which offers scientific evidence-based treatments for sleep breathing disorders.


Our practice collaborates with a multidisciplinary team of physicians and oral surgeons to deliver specialized care for airway issues.

Sleep Breathing Disorders

Sleep breathing disorders are conditions that involve abnormal and difficult respiration during sleep. They encompass a range of issues, including chronic snoring, obstructive sleep apnea, and central sleep apnea, each affecting the quality of sleep and potentially leading to serious health consequences if untreated due to the impact on the body's oxygen and carbon dioxide balance.


Dr. Rooz works with a specialized team to address pediatric sleep apnea treatments. At PORTH, we provide various treatment options for children with sleep breathing disorders.
