Our Patients Are Saying...

The best dentist we have gone to. My husband, children and I had a lot of work done by Dr. Horiyat. He had an operation, I got veneers. Every procedure was administered with excellence.

From the start Aria dental has impressed me with how my health, comfortability and satisfaction in care are their top priority. They are a fully metal free implant center. They helped me when I had a seriously infected tooth go unnoticed by my original Dr. I was feeling pain on and off in that tooth and my original dentist didn't say anything. I wanted a 2nd opinion so went to another dentist covered by my insurance who originally found the infection. That dentist offered me a root canal which used medication and metal. I was looking for a more holistic approach that had minimal side affects. Watch "Root cause" to educate yourself on the harm's of root canals. Aria dental used an advanced type of photo imaging to detect my infected tooth. They extracted my tooth and gave me option of conscious sedation. I HEAVILY reccomend you take the this if needing an extraction. They used PRP on me to speed up my healing time and they offered me ozone to kill infection much better than what's typically used at dental offices. I healed very well although there was some expected pain/swelling for 3 days after. 4 months later I went in for my zirconia implant. They take an imaging photo to insure the bone the place in your jaw is ready. This time it was not as painful but I still opted in for conscious sedation. I was in and out fast and barely any noticeable pain the next day. Between getting the extraction and getting the implant they fitted me with a retainer so that there was no shifting of my teeth. My tooth extracted was in the back so I chose to now have a temp tooth. My 1st retainer broke because I grind and they replaced it with a thicker material free of charge. Dr Mariyam is very knowledgeable about total body wellness and how the teeth are linked to meridians and organs of the body. I have referred a friend here who also had an infected tooth extracted and had a good experience. She had autoimmune problems and thyroid problems that are much better 2 months later. Everyone there is easy to talk to, friendly and wants you to feel comfortable at all times. They offer headphones with peaceful frequency music which is a nice touch. Steve and the front went over payment options with me and always rescheduled me with ease if need me. I am very grateful for the team at Aria dental. .

I would give more than 5 stars if I could. I've had a large amount of dental work throughout my entire life, largely restorations and repairs in recent years. Throughout, I've encountered a number of dental specialists in a variety of locations. Not all bad, but many were less than positive experiences. Then I found Dr Horiyat and Aria Dental while searching online for a holistic and health-promoting dental practice. I've had 3 visits so far (chipping away at an extensive treatment plan), and I could not be happier with my experience. Highly professional, relatable, warm and engaging, and most of all, truly an exceptional level of professionalism. They are awesome at their craft. Thank you Dr Horiyat and all of the Aria team (Hassiba, Steve, Mariyam, Stephanie...I'm talking about YOU).

Today Connie was my dental hygienist. She took her time carefully handling my cleaning, explaining the process. She regularly asked for my feedback and checked on my comfort level. Today as in all previous visits the service and support has been exceptional. Dental surgery has been amazing. It has been quick and painless, followed by no infections and prompt healing. This is the first time in my life (blessed long life), I can leave a procedure and proceed with my day. Previously, I would be uncomfortable and over medicated, the procedure would also require a longer healing process. I feel very confident with the dentists, surgeons and hygienists. Office staff is wonderfully supportive and friendly. This is my lifelong dental office.
I’m not a fan of going to the dentist but then again I’m writing a review for one. Dr. H is amazing to say the least. Her knowledge of dentistry goes far beyond just the teeth. Why else would anyone post YouTube videos regarding all types of health concerns that may be caused by our mouths or what’s inside? I better give props to Connie as well. She barely scared me with those sharp instruments:) Definitely won’t go anywhere else!

Absolutely the very best experience my husband and I have ever had at a dentist. All the staff is top notch professional, efficient, kind, and helpful. If you have been dissatisfied with traditional dental procedures like root canals, extractions, gum disease treatment, etc., please go get another opinion from Dr. Horiyat. She offers cutting edge technology that can solve many dental problems more efficiently, less invasively, and much better than traditional solutions. She's the absolute best!
