Wand STA

Single Tooth Anesthesia technology in San Diego – Fremont Dental Arts

What is Single Tooth Anesthesia technology?

The source of discomfort for most injections, isn’t the needle – it’s the flow of anesthetic. The Wand allows for a consistent and optimal flow rate, making the injection process more comfortable.

Key benefits of Single Tooth Anesthesia (STA):


  • Higher Patient Comfort 
  • Reduced Patient Anxiety
  • Faster numbing onset and sensation recovery
  • Great for pediatric patients
  • Precision intraligamentary injections
  • No more blocks necessary – anaesthetise one tooth, without collateral numbness
  • Painfree palatal injections, allowing you to view the smile-line immediately


The STA Single Tooth Anesthesia System® combines patented, state-of-the-art computer-controlled injection technology that achieves more precise injections, improved drug delivery and materially enhanced patient comfort levels. The unit additionally provides a flow of anesthetic directly ahead of the needle creating a “pathway of anesthesia” to further decrease the uncomfortable feeling generally associated with a dental injection.

“The Wand STA system numbs faster and more accurately.”

For a typical procedure, the Wand STA system numbs faster and more accurately. Uncomfortable numbness seems to disappear faster.  A busy professional can now have a cavity filled at 10:00 a.m. and attend a business meeting at noon without the facial numbing that can cause slurred speech and drooling. Limited doses of anesthesia also reduce hepatotoxicity (liver toxicity) which is an added benefit of using the Wand STA.
