Every kind of care, one address
General, cosmetic, and implant dentistry, oral surgery, and sedation are all handled in our office, so a Newport Beach patient isn’t sent across the county for a specialist.
An implantologist on site
Dr. Polonus plans, places, and restores dental implants himself — from a single tooth to full-arch all-on-X reconstruction.
