Actual Patient Testimonials

I had the most pleasant experience when Dr Steven Koos did my implant surgery a couple of days ago. From the start to the end of the procedure I felt very comfortable and relaxed.

Amazing; Dr. Koos is so thorough, kind and skilled. I felt nothing. Afterwards he explained everything to my family and I went home.

Dr. Koos is a great oral surgeon. He is very knowledgeable. I had my wisdom teeth pulled with barely any pain after the procedure.

I recently had my wisdom teeth removed. I had such a wonderful experience.  The staff was outstanding and very friendly.

Wisdom Teeth Removal

No Anxiety. Urgent Care.

Wisdom teeth, also known as third molars, are the last teeth to erupt in your mouth, generally between the ages of 17 and 25. A tooth becomes impacted when there is a lack of space in the dental arch and its growth and eruption are prevented by overlying gum, bone or another tooth.

Dental Implants

Improve Your Smile.

Dental implants are the single most important advancement in dentistry offering a modern day solution for missing teeth. Implant based dental restorations look, feel, and function just like your natural teeth. They can support an active lifestyle and can give you back the quality of life you deserve.

Pleasantly surprised by post-surgery follow up

It was a pleasure to have straight forward information provided and constant follow up after my surgery. I was pleasantly surprised to receive a call from Dr. Steven Koos late at night to make sure I was having a healthy recovery. And the cherry on top of the ice cream was how updated the office was. State of the art equipment that I had no doubt I was in good hands.

Great place and great staff.

Great place and great staff. I was well informed about the entire procedure and the follow up process. I also felt very at ease knowing the doctor called me later in the day and him providing me his number in case anything happens.

Earns my trust for comfort and care

I had two implants, a sinus lift and one other procedure within the last year or so. I can’t speak highly enough of Dr. Koos and his staff. I was well informed about my needs and next steps. And more importantly, all went well with very little discomfort. I’m usually a little skiddish when it comes to dental surgery and any associated pain. ORA Oral Surgery & Implant Studio earns my trust for comfort and care.
