Dentistry is micro-surgery. Drs. Bengtson and Freese utilize high powered magnification and illumination to help provide incredible accuracy of detail of your dental restorations. You just can’t fulfill that level of care with the naked eye.
Many dentists use air-driven “hand-pieces” (the dental term for “drills”). While acceptable for many procedures, these “whiney sounding” air powered hand pieces all have a degree of non-concentricity; they do not rotate perfectly smoothly.
