Lynn Sayre-Castairs, MD


Over the past 25 years, Lynn Sayre-Castairs, DMD, brings passion and dedication to her practice at Coast Periodontics and Laser Surgery. Dr. Sayre-Castairs provides wonderful, gum disease dental care for people ages 12 and older living in and around San Luis Obispo, California. 

 Education plays a fundamental role in Dr. Sayre-Castairs’ approach to dental care. She began her studies at Wellesley College in Wellesley, Massachusetts, earning her bachelor degree in psychobiology. Following her degree, she enrolled at the University of Southern California for her post-graduate studies in periodontology before completing her Doctor of Dental Medicine at Tufts University School of Dental Medicine in Boston, Massachusetts. 

She is also an active member in the dental community, proudly holding membership in several professional organizations, including the Central Coast Dental Society, California Dental Association, American Dental Association, American Academy of Periodontology, American Academy of Laser Dentistry and International College of Dentists. 

 In 1995, Dr. Sayre-Castairs created Coast Periodontics and Laser Surgery. Since that time, she has treated patients with a variety of gum health conditions. Her experiences with patients have led to a desire to pursue further educational opportunities around the world, seeking and discovering the latest technology for her dental practice.  

Dr. Sayre-Castairs strives to diagnose and treat gum disease early on to reduce the risk of potentially serious issues, including tooth loss and bone decay. She uses advanced diagnostic techniques and treatments, while trying to help her patients preserve their natural teeth as much as possible. 

 At Coast Periodontics and Laser Surgery, she offers a variety of non-surgical and surgical treatments for gum disease to help patients enhance their oral health and achieve their ideal smile. 

When she isn’t participating in continuing education or researching the latest technology to improve oral health, Dr. Sayre-Castairs enjoys spending quality time with her husband, their three sons and grandchildren. 

 As a family-oriented dental practice, Dr. Sayre-Castairs welcomes anyone seeking treatment for gum disease to the Coast Periodontics and Laser Surgery office in San Luis Obispo, California.
