Digital X-Rays

Our digital X-rays emit less radiation, take images faster without any need for processing, and allow us to optimize the images so we can provide a more precise diagnosis.

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.
