A smile transformation by Dr. DiVanna, currently in progress and already looking incredible! ✨

This case combined aesthetic crown lengthening on tooth #7 to create harmonious gingival heights, along with a carefully planned combination of crowns and veneers from #7–11 to achieve a natural, balanced result while preserving as much healthy tooth structure as possible.

By blending restorative and periodontal treatment, we were able to improve symmetry, close black triangles, and create a seamless smile with consistent shape, color, and contour.

This patient is currently in the middle of treatment with additional restorations planned, but even this phase created a dramatic change.

Call our office to learn how we can help you feel more confident in your smile! 😁

No more messy molds! Say hello to our intraoral scanner, a handheld device that uses a series of 2D photos to build a 3D image of your mouth. This technology helps us ensure a perfect fit for crowns and bridges. Files are sent to the lab instantly, resulting in a much shorter turnaround time for patients.

By investing in advanced tools like this one, we are able to create a more comfortable, efficient experience from start to finish. When dentistry evolves, your care should too.
