"I Can't Work Without It": A General Dentist's Take on Buffered Anesthesia

Profound Anesthesia Onset: Dr. Rob DiVito's Take on Onset EZ

Beyond the Guesswork: Success Stories from the Operatory

"I’ve found the EZ Pen to be a total game-changer for elevating the patient experience and eliminating the fear of needles. Since incorporating it three weeks ago, my patients have reported that they no longer feel the stinging "zing" sensation during local anesthesia, allowing for a virtually painless injection. I strongly recommend the EZ Pen to any dental practice looking to alleviate patient anxiety and provide a more comfortable, high-quality clinical experience." -Dr. Derek Song

"We recently got the Onset system and have been using it regularly for our surgeries. The one thing I really like is that it allows me to proceed with our procedures right away. Patients are numb almost immediately after the injections, with very minimal wait time. It has saved me a considerable amount of time, which naturally translates to a more efficient and productive practice." -Dr. Adam Parikh

"I’ve been using Onset for about two weeks now, and it is a total game changer. It numbs instantly and takes the guesswork out of the process. Because you aren’t waiting for anesthesia to kick in, you can see more patients and never feel rushed. It’s one of the few things that truly increases your production." -Dr. Benjamin Hale
