Laser Cavity Detection

DIAGNOdent laser technology allows us to precisely test your teeth for cavities beneath the protective layer of your enamel. By taking laser readings, we can detect cavities in their smallest phase of development so we can treat you before it becomes a bigger problem. This approach saves you time and money!

Digital Dental X-Rays

Digital x-rays are more accurate, higher resolution, and lower in radiation. They allow us to detect decay early and treat it right away. Lower radiation means higher safety measures for you. Digital dental x-rays are up to 80% lower in radiation than traditional film x-rays.

Digital x-rays also allow us to monitor changes in your health over time and digitally transfer records quickly.
