Discover Your Outstanding Dentist in Irvine


SCOTT M. WATANABE“I am blessed and privileged to help others as a dentist. I have grown up with this dental practice. As a child, I ran the halls and helped file patient charts. I feel honored to be able to practice with my mentor and father, Dr. Ronald T. Watanabe, who started this practice in 1980. I work with a wonderful, caring and experienced staff, which includes my mother, Joan.
“My practice is here to educate and help our patients with improving their oral health. I am passionate about creating a beautiful smile, and I believe it takes careful planning and consideration. I treat patients of all ages. I value getting to know my patients and believe it is rewarding to see how dentistry can bring positive change. Welcome to my practice! I’m excited to share our passion for dentistry with you.
“I regularly attend advanced continuing education because I think it is valuable to employ state-of-the-art technologies and up-to-date materials to provide the latest in clinical advancements.
“In all areas of dental health, Arbor Dental Group is focused on providing you an outstanding experience. We strive to deliver to you dentistry and service that will consistently exceed your expectations. Our staff is dedicated to hearing your concerns, understanding your specific needs and building a lasting relationship with you.
“I met my wife after graduating from dental school. We were married in 2009 at Mariners Church in Irvine, where you can find us on weekends. Our lives are filled each day with family. We have two sons, Matthew and Weston, and we welcomed baby #3 on July 5 2016, our beautiful daughter, Kate. We have a rescued dog, Joey. My family and I reside in Irvine, where I grew up. I enjoy running, hiking and following sports, like my college team, CAL. Go Bears!”

RONALD T. WATANABE“Welcome to Arbor Dental Group! I am proud to be a founding member of Arbor Dental Group, which was started in 1980. Our group philosophy provides patients a wide range of providers and services to give open options for appointment times and treatment consultations. Our core philosophy is to offer excellence in family dental care in a friendly, warm environment.
“My interest in dentistry began at a very early age. A dentist spoke to our fourth-grade class about oral hygiene and proper nutrition. This inspired me to write an article about proper oral healthcare and nutrition, which was published in the school newsletter. I was also inspired, as a teenager, by my next-door neighbor who was our family dentist. He was kind enough to talk to me about a career in dentistry and gave me advice regarding the educational path to take to become a dentist. I focused on the goal of being a part of the dental profession throughout college and was excited when it became a reality. The profession has proved to be everything I had hoped.
“I love having a close one-on-one working relationship with people. I enjoy improving their general health, self-image, appearance and confidence. The dental profession, as other medical fields, is constantly evolving. Paper records and charts, chemically developed radiographs and impression materials have evolved into a new technology of computer data, digital radiographs and digital CAD/CAM imaging. Dental materials have been developed that provide improved esthetics and durability. Technology has provided innovative ways of tooth replacement. It has been exciting to see the constant evolution and innovations of the profession. What has not changed, though, is my goal to give an interactive, patient-centric dental experience. Treatment plans are customized and carefully planned to keep in mind the individual needs and desires of each patient. I, as well as the other members of Arbor Dental Group, am dedicated to providing precise care of the highest quality possible with a calm, gentle, comfortable experience using the most current, contemporary technology available.”

Kelly IMG“My mother is a dentist and my mentor. I love working with healthcare, art and people. Dentistry is a great combination of those things. I am a teacher at heart. I focus on prevention and treat conservatively. Education and a healthy mouth are the most important things I can give to my patients.”
