Single Tooth Anesthesia (STA)

For the nervous patient, Dr. MacFarlane is pleased to use the STA (Single Tooth Anesthesia) system to more comfortably administer anesthesia.  The STA system is a computer-controlled dental injection system that helps to make your visit more comfortable and your experience at our office more relaxing.

The STA system uses something that looks like a ball point pen. The miniscule needle is located at the end of this pen-like device.  When using the STA system, a computer controls the flow of anesthesia, resulting in reduced human error and more comfort for you.

The STA system has many advantages, including:

• Non-threatening appearance
• Precise anesthesia flow rate
• More effective
• More comfortable for you
