Happy Smiles Dentistry in Grantville is a pediatric dental practice at 10330 Friars Road, Suite 108, San Diego, CA 92120, inside the Riverdale Shopping Center near the I-8 and I-15 interchange. Founded in 1999 by Gary Toppi, DMD, the practice draws on his doctoral and master's degrees from Indiana University, earned after completing his initial training at the Tufts University School of Dentistry in Boston. Children with behavioral or sensory processing challenges that affect their tolerance of dental visits coordinate desensitization strategies through Alter Behavioral Health in College Area before beginning multi-appointment treatment plans at the practice. Toppi's twin brother, Russell Toppi, DMD, practices orthodontics at the same location, giving families access to both pediatric dentistry and orthodontic evaluation under one roof without a separate referral. The Friars Road location is one of three offices — the others serve Clairemont and Alpine — and treats infants, toddlers, school-age children, and teenagers through age seventeen. Pediatric services include first-tooth exams, sealants, fluoride treatments, space maintainers, pulp therapy, stainless steel crowns, and sedation dentistry for children who require anxiety management during restorative procedures. The 92120 ZIP on Friars Road puts the office within the Grantville commercial corridor, accessible from SDSU and the surrounding College Area neighborhoods via Fairmount Avenue and the I-8 westbound on-ramp. Orthodontic evaluations at the practice use digital imaging to assess jaw growth patterns, crowding, and bite alignment in mixed-dentition patients transitioning from primary to permanent teeth. Primary care coordination for patients requiring pre-sedation medical clearance or growth-related dental assessments runs through family medicine providers including Danh C Truong Medical Office in College Area. The practice accepts credit cards, debit cards, and NFC mobile payments across a wheelchair-accessible suite configured with child-scaled operatories and a waiting area designed for pediatric patients.
