What Our Patients Say

From my first time calling in I knew we had made the right choice! Crystal was warm friendly and made us feel at home right away. When we met with Elly for our consult things just got better. She explained our options very thoroughly and answered all our questions. My daughter was excited and a bit nervous but Dr Rooz made her feel comfortable immediately. He was kind and direct about what she would need and she liked him so much she asked when we could come again! We will definitely be recommending him to everyone we know!

Shea M.

This is my second time having braces in my life but first time as an adult and I must say, I am so glad I found Porth! The staff here are so incredibly friendly and the office itself is very clean, modern, and welcoming. Dr. Rooz is very attentive and explains everything in terms that I can fully comprehend. You can tell he genuinely cares about his patients and about teeth. I love the fact that they use 3D scans instead of teeth impressions that always made me uncomfortable. Highly recommend to anyone in the market for an orthodontist!

Juliana M.
I freaking love this place! Dr. Rooz has gone completely out of his way to help me stay on my plan while I’m out of state. The team is super friendly and very accommodating. The customer service is outstanding and in my opinion they are changing the game to ensure all their patients needs are met! There’s no way you can go wrong with this incredible team!

What to Expect at Your Orthodontic Complimentary Consultation

What Do You Learn at Your Complimentary Consultation?

Whether you like to fix your crooked teeth or bad bite, the first stop is a visit to an orthodontic clinic. At PORTH, we start with collecting a scan of your teeth, then a 3D xray of your head. Our state-of-the-art ortho facility is designed to give you an exceptional experience while we build you a beautiful smile.

Orthodontists go to dental school to learn about dentistry to obtain a DDS or DMD. Orthodontics is a specialty branch of dentistry. They specialize in straightening teeth, fixing bites, and improving oral health. This helps prevent tooth decay and gum disease. They also focus on creating a healthy smile.

Treatments for Sleep Breathing Disorders


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.
