Phil J. Ra DDS, FAGD, FICOI

Dr. Phil J. Ra was raised in Southern California and currently takes pride in residing and practicing the art and science of dentistry in Upland and the surrounding areas. His childhood goal of becoming a dentist became a reality when he was accepted into the prestigious six-year Accelerated Dental Acceptance Program Tract (ADAPT) at the University of Southern California School of Dentistry right out of high school in 1994. Dr. Ra is proud of this accomplishment, as only a select group of students in the nation are accepted into this academically rigorous and clinically grueling accelerated program.

After becoming one of the youngest doctors to graduate with a Doctor of Dental Surgery degree in the history of USC in 2000, Dr. Ra spent several years (and still spends many hours) attaining up-to-date continuing dental education and training to better serve the Inland Empire for over 15 years. . His unwavering commitment to staying on top of dentistry's latest techniques and research has earned him the highly prestigious Fellowship from the Academy of General Dentistry. This means he has the skills gained from more post-doctorate education in 3 years than the State of California requires dentists to take in 20 years of practice.

In 2007, Dr. Ra received the "Top Dentists in America" award, given annually by the Consumer Research Council to selected dental healthcare professionals. Starting in 2008, Dr. Ra was extremely honored to be voted as one of the "FAVORITE DENTIST OF THE INLAND EMPIRE" by the Inland Empire Magazine for 7 years straight.

Currently, Dr. Phil J. Ra is a member of the ADA, AGD, IAOMT, and the ICOI and has a FELLOWSHIP in the Academy of General Dentistry (AGD) and FELLOWSHIP in the International Congress of Oral Implantology (ICOI) and also an Associate Fellow from the World Clinical Laser Institute (WCLI). Dr. Ra is one of the very select few in the Inland Empire to be certified in the LANAP (Laser Assisted New Attachment Protocol) and was one of the first doctors to be trained in the pinhole gum rejuvenation procedure. He is also actively involved in organized dentistry, previously serving as a board member in the Southern California Academy of General Dentistry. Dr. Ra was a regular contributor to dental health articles for the Inland Empire Family Magazine and is also a manuscript peer-reviewer for the General Dentistry magazine, which is the leading peer reviewed publication for the general dentist. He is also involved in numerous study clubs in order to maintain the latest knowledge in cutting edge dentistry.

Dr. Ra practices Biologic Dentistry and maximizes the power of cavity re-mineralization, alkalization of the mouth, and other homeopathic and minimally invasive techniques to help every patient be as healthy as possible.

In our Upland dental office, patients have the opportunity to complete dental material compatibility testing. This test will inform your dentist of any reactivity within your body to specific dental materials. Dr. Ra only uses the most biocompatible materials.

Our office uses the latest in digital dental radiographs, digital 3D radiographs (CBCT), digital photography, and polarized infrared light (diagnocam technology) to offer the safest and most accurate diagnosis. We also employ CEREC (CAD/CAM Technology) which allows us to perform same day permanent conservative biocompatible restorations. This is convenient for our many patients who travel in from out of the area for treatment.

The 3D (CBCT) is a wonderful technology employed to evaluate root-canalled teeth for cracks and chronic infections that potentially leak pathogenic bacteria into your body. When needed, this technology is used to perform simple guided flap-less implant surgery. This is the least traumatic and least painful implant procedure.

Another great advantage to Dr. Phil Ra's SmileStudio is his "in-house" dental laboratory. When aesthetic services are needed or desired, no work is out-sourced from the office. Our in house lab allows perfect communication of patients' desired outcomes to the ceramist fabricating the crown or veneer. We perform custom smile design, custom shade matching, and in house quality control using the highest quality ceramics in existence. Whether it is one tooth in the front of the mouth or your entire smile, our in-house laboratory ensures your aesthetic desires are met and exceeded.
