State-of-the-Art Technology

Our team utilizes the latest advancements in cosmetic dentistry technology. From digital smile design software to minimally-invasive techniques, we prioritize precision and comfort throughout every procedure. This ensures not only superior aesthetic results but also a pleasant experience for our patients.

Digital X-Rays

Digital X-rays offer crisp, high-resolution images while using a fraction of the radiation of traditional X-rays. Digital X-rays are a more efficient and accurate way to detect dental concerns.

iTero Digital Scanners

The iTero Digital Scanner captures precise 3D impressions of your teeth, completely replacing the need for traditional, messy molds. It enhances the accuracy of treatments like Invisalign® and custom dental restorations.

Intraoral Scanner

We use our intraoral camera to take a detailed look inside your mouth, capturing clear images of your teeth and gums. These images are displayed on a screen during your visit, giving you a firsthand view of any issues we spot.

Intraoral Camera

An intraoral camera lets us take high-resolution, close-up images of your teeth and gums, giving us a clearer, more detailed view than traditional mirrors alone.

Cone Beam Computed Tomography

Cone Beam Computed Tomography (CBCT) creates detailed 3D images of your teeth, jaw, and surrounding structures, giving us a complete view for highly accurate treatment planning. This is valuable for procedures such as dental implants, orthodontics, and complex tooth extractions.

Soft Tissue Laser

A soft tissue laser allows us to perform gum treatments with greater precision, minimal discomfort, and faster healing. This advanced technology reduces bleeding and swelling, making procedures like gum contouring or periodontal therapy more comfortable and efficient for patients.
