Why Onset Works

After injection, the body must raise the pH of the local anesthetic towards physiologic (~7.4) before the patient can achieve pulpal anesthesia. Standard dental cartridges take time and keep you, your staff and patients waiting while the body works to raise the pH towards physiologic.

Buffering raises the pH of local anesthetic closer to physiological, making your local anesthetic of choice better and more predictable. Onset lets you buffer cartridges of local anesthetic at chair side immediately before delivering the injection, making buffering simple, convenient and predictable.

A more predictable injection

Use Your Own Local Anesthetic

Onset can be used to buffer standard dental cartridges of articaine, lidocaine, mepivacaine, and prilocaine. It only takes seconds to buffer the local anesthetic of your choice with our Onset Mixing Pen!

Use Your Own Syringe

With Onset, there’s no need to change your syringe or learn a new injection protocol. Once buffered with our Onset Mixing Pen, you place the local anesthetic cartridge in your own syringe and give the injection using your own injection technique.
