Digital X-Rays
Digital X-rays dentistry in San Francisco, CA, produces detailed images of teeth, bone, and surrounding structures that are not visible during a routine exam. These images appear quickly and enable the dentist to evaluate conditions such as decay, bone loss, or infection. The process uses lower radiation compared with traditional film while improving diagnostic clarity. This enables early detection and guides treatment decisions based on accurate visual information.
iTero Scanners
The itero scanners dentist near you system captures highly detailed 3D images of both teeth and gums without the need for traditional impressions. This technology enables dentists to evaluate alignment, spacing, and bite relationships with clarity. Patients often find the scanning process more comfortable compared with conventional molds. The digital models also simplify reviewing findings and planning treatments such as orthodontics or restorations with greater predictability.
Intraoral Camera
An intraoral camera records clear images inside the mouth using a small handheld device. With intraoral camera dentistry, patients can view real-time images of their oral condition during the exam. This visual approach strengthens communication and helps patients better understand areas that may need attention. It also enables early identification of concerns before they develop into more complex issues.
Intraoral Scanner
An intraoral scanner captures highly accurate digital impressions of your teeth, allowing your dentist to evaluate tooth shape, spacing, bite, and alignment with exceptional precision. Replacing traditional impression materials with intraoral scanners improves treatment planning, enhances communication with dental laboratories and specialists, and most importantly provides a faster and more comfortable experience from start to finish.
In-House 3D CBCT Scan
An in-house 3D CBCT scan delivers a detailed three-dimensional view of teeth, bone, and surrounding structures. This advanced imaging evaluates areas that cannot be fully examined with standard X-rays. These advancements allow for the planning of implants, complex extractions or airway evaluation. The ability to review structures from multiple angles broadens and strengthens informed clinical decisions.
Laser Dentistry
Dental lasers allow your dentist to perform soft tissue recontouring and certain periodontal treatments with exceptional precision. By targeting affected tissue while minimizing disruption to surrounding areas, laser dentistry can enhance treatment accuracy, improve healing, reduce discomfort, and create a more comfortable experience compared with many traditional soft tissue procedures.
