Numb in seconds.
Not minutes.
The Onset EZ™ Pen buffers individual cartridges of local anesthetic to a neutral pH — eliminating the sting, the wait, and the guesswork.
Anesthesia, the way it was meant to work.
Standard local anesthetic is acidic — that's why it stings and why onset takes so long. Buffering raises the pH to physiologic levels right before injection.
Fast & Easy
Buffer a cartridge in under 3 seconds. No training. No assembly. Just press and go.
Painless Onset
Patients report no stinging 'zing' — a virtually painless injection that calms needle anxiety.
