About Our Office

As a periodontist, we can help treat issues that impact the support structures of the teeth and related oral health issues. While oral hygiene at home can help with one's overall oral health, there are a variety of health issues that require periodontal treatment. We also offer laser surgery for certain procedures to enhance the procedure. Our goal is to help treat any issues and help you achieve the ideal smile you desire.

By scheduling a consultation with us, we can develop a customized treatment plan for your needs. With this plan, we can also address any concerns or fears about the procedure. Our priority is your health and wellbeing following the procedure. Thus, we will provide follow-up care when necessary to help ensure everything is running smoothly.

If you are interested or in need of periodontal treatment, call us at 805-952-1147 to schedule an appointment today.

Dr. Sayre-Carstairs

Dr. Sayre-Carstairs joined Coast Periodontics in 1995 and over the last 25 years as the dentist and practice owner, she has transformed the services this periodontal specialty practice offers the residents of the Central Coast. Primarily with the addition of the use of lasers both surgically and non-surgically, the change of the practice name – Coast Periodontics and Laser Surgery – better reflected the services she provides. Dr. Sayre-Carstairs has always been on the cutting edge of options for patients suffering from gum disease and prides herself on always trying to help periodontal patients keep their natural teeth. This desire has led to countless hours of continuing education around the world seeking the latest technologies to improve oral health.

Dr. Sayre-Carstairs is a graduate of Wellesley College in Wellesley, MA. Her BA degree is in psychobiology and her research focused on olfaction. Her DMD degree is from Tufts University School of Dental Medicine. Upon graduation, Dr. Sayre-Carstairs moved to Los Angeles to begin the periodontal program at the University of Southern California. She graduated in 1988.

Dr. Sayre-Carstairs and her husband Greg, a life-long Central Coast resident, enjoyed raising their 3 sons and now enjoy watching their growing number of grandchildren explore the world.
