John U Choi DDS, PhD

Specialized gum care gets precise here. John U Choi DDS, PhD operates a periodontist practice in Fullerton, tucked into the professional suites along Bastanchury Road. The office sits just off the 91 freeway—convenient for anyone navigating the stretch between Anaheim and Brea. Periodontists handle the kind of dental work that goes deeper than cleanings: gum disease treatment, dental implants, bone grafts, and those meticulous procedures that keep your foundation solid. It’s the kind of place you’d seek out after a general dentist refers you for something beyond their scope; no walk-ins for routine checkups here.

Parking in this part of Fullerton is typically plaza-style, shared with other medical offices and a smattering of small businesses. The address—301 W Bastanchury Rd #255—puts it near the kind of strip-mall pragmatism that defines so much of Orange County’s healthcare landscape. Questions about procedures or insurance? The front desk fields calls at (714) 449-8650. For first-time visitors, the map shows the suite tucked into a two-story complex; look for the numbered signs.
