Digital X-Rays

Digital X-rays are an essential diagnostic tool. They allow us to carefully examine the health of your teeth and jawbone, diagnose health concerns, and design treatment plans without the need for traditional film X-rays. Compared to film X-rays digital X-rays omit up to 90 percent less radiation.

Intraoral Camera

This innovative handheld camera allows us to examine your mouth in greater detail. We use this diagnostic tool to zoom in closely on specific teeth, providing a high-quality image of your teeth. The images are displayed on a screen for you and our dentist to review, giving you a better understanding of your diagnosis and treatment.

A Dental Cone Beam/Tomography X-Ray Machine

Cone Beam Computed Tomography

Known as CBCT, this advanced imaging technique uses a cone-shaped X-ray beam. The cone beam rotates around your head to create a highly detailed 3D image of your mouth to help us accurately design your treatment plan.
