Dental Care for the Whole FamilyPicture of a family with healthy teeth

Achieving life-long oral health starts at an early age and requires constant care that adapts to changes in the smile. At Ontario River Arch Dental, we provide comprehensive treatment plans that cater to patients’ ages, needs, and personal aesthetic goals. From sealants for children to zirconia crowns for adults, our priority is helping you achieve optimal oral health while preserving your dental aesthetic.

Our Ontario family dentist offers a number of cosmetic, preventive, and restorative treatments, including:

Providing the right care for every smile begins with understanding each person’s unique oral healthcare needs. Dr. Dinh uses imaging tools such as intraoral cameras and digital X-rays in order to take a closer look at your smile. We encourage our patients to ask any questions they may during care, and work with them to develop treatment plans that make them comfortable and confident in the care they receive.

Accessible, Affordable Dental Care

While the primary focus of our Ontario dental practice is the preservation of proper dental health, we work to ensure that restorative and cosmetic treatments are affordable and accessible. We accept a number of HMO and PPO dental insurances and offer financing through CareCredit to make receiving care as stress-free as possible.

In order to sustain our patients’ dental health, Ontario River Arch Dental offers 24-hour emergency dental care. Emergencies and tooth pain are not only uncomfortable in the short term but can have a lasting negative impact on oral well-being. If you are experiencing a true emergency call (909) 923-2273 today to alleviate your pain and restore your health.
