Welcome to In Line Dentistry

Meet Dr. James Chon, a dentist with heart

Dr. James Chon’s journey to dentistry was sparked by a transformative dental mission trip to Guatemala after college. That life-changing experience inspired him to pursue a path centered around compassion, healing, and care. He completed his undergraduate studies at UCLA and earned his DMD from UNLV in Las Vegas. Dr. Chon is committed to helping patients regain their ability to smile, eat, and live pain-free lives. For him, dentistry is more than fixing teeth: it’s about restoring confidence and connection.

Outside of the practice, Dr. Chon enjoys time with his wife and daughter, bonding over sports, and cooking big meals for friends and family. He brings that same warmth and sense of community into every patient visit.

Compassionate care from a team you can trust

At In Line Dentistry, the team is passionate about providing care that goes beyond the clinical. Office Manager Isabel is exceptional at working with insurance to help patients maximize their benefits, while Assistant Sebastian makes a real difference by explaining each procedure step-by-step, helping ease anxiety and build trust. Together, they work with Dr. Chon to create a space where patients feel heard, cared for, and completely comfortable.

While the office isn’t flashy or boutique, it’s clean, inviting, and equipped with amenities to make your visit smooth and stress-free, such as TVs in every operatory, calming tones, and modern touches.

Focused on cosmetic, implant, and restorative care

In Line Dentistry specializes in cosmetic and implant dentistry, offering services like cosmetic makeovers, veneers, teeth whitening, and full-arch implant restorations. Dr. Chon loves the impact these treatments can have, from restoring function and appearance to boosting self-esteem, with a gentle and thoughtful approach. Patients come in unable to eat or smile confidently, and walk out feeling transformed.

The practice also offers high-quality restorative care including crowns, bridges, fillings, and dentures. Whether you're looking to rebuild your smile or enhance its beauty, In Line Dentistry provides treatment that’s personalized, effective, and centered on your comfort.
