Dr. Oscar and Blanca Esparza

Dr. Oscar and Blanca Esparza have been serving the community of Ontario, CA for nearly 20 years. Both Oscar and Bianca graduated from the School of Dentistry of the University of Durango, Mexico in 1984 and shortly after got married and began practicing dentistry in Durango. In 1996, the Esparza’s relocated to Southern California to open their own practice after receiving their California Dental license. They have been practicing dentistry in Ontario ever since. The doctors are blessed with three children, two of which are pursuing dental careers of their own. Dr. Oscar and Blanca are proud to treat and improve the quality of life for patients from all walks of life, and constantly strive to provide patients the best of dental services: ranging from restoring a cracked tooth to delivering dentures, and even performing complete smile makeovers! In 2013, Dr. Blanca was awarded the Woman of the Year award from the National Association of Professional Women.



I recommend Dr. Esparza because he genuinely cares about one's dental health and ensures any dental work that is being performed is done correctly.
