The STA System™ with The Wand™ The Wand is a computer-controlled anesthetic wonder! A technology that has been clinically proven to provide a pain-free injection. Now, we can target the precise area for treatment, even a single tooth, with just one shot. That's why it's called STA, or single tooth anesthesia. Best of all, it requires only one to two minutes to become effective, as opposed to administering an anesthetic that numbs your entire lip and takes 8 to 12 minutes. Not only is this a more accurate and safer delivery of anesthesia, but the STA lasts as long as traditional anesthesia. That's what we call a medical advancement!
