The word “core” is often defined as being a central aspect or foundational part of something. Much like healthy teeth, bone, and gums are the core of good oral health, the mission of our practice is to provide you with the foundation to help support healthy oral habits through early detection and preventative measures.
Amid the stigma many still attach to dentistry, our practice emerges as a long-standing dental home characterized by genuine, welcoming dentists and personalized care. And, as a reflection of our name, we aim to provide all patients with Compassionate, Organized, Reliable, and Experienced oral health care.
We welcome you to experience the difference CORE Dental can make!
