Single Tooth Anesthesia (STA) Wand

Family & cosmetic dentistry in St. Louis, MO

Patient comfort is one of our primary concerns, so we are proud to have integrated the STA system into our practice. CompuDent, which is the brain behind the STA system, is a computerized local anesthesia delivery unit. The STA uses a tiny needle to administers the anesthesia to a single tooth, preventing numbness of the lips, nose, and face.

How it Works

Injections can be irritating for many reasons, but one pain factor is that the anesthesia is concentrated in a small area until it dissipates. Anesthesia administered too fast can also cause pain. Another irritation stems from too much tissue going numb, which can leave a patient drooling after an appointment.

CompuDent manages the flow and volume of anesthesia being delivered, and it also offers more accuracy for the area being numbed. The STA pen-sized wand, through which the regulated anesthesia flows, does not look or feel like a syringe. A drop of topical numbing agent first numbs the injection site, and then the needle creates a comfortable injection pathway.
