15% of Americans fear going to the dentist, and 40% do not go at all.
A trip to the dentist can be especially painful for patients who have had the roof of their mouth numbed.
The traditional way to curb pain is to apply static pressure with a mirror handle.
The pressure acts like a closed gate, blocking the initial prick of the needle, but it is not foolproof.
Doctor Joseph Kravitz DDS says half of his patients still feel excruciating pain.
After searching for a better method, he found rolling the mirror handle just 2-to-4 millimeters increases pressure and blocks pain.
Dr. Kravitz also said, "The gate switches to directly where the needle gets inserted and you can not feel the pain. Every single time and that is revolutionary."
Doctor Kravitz's groundbreaking theory works 99% of the time.
If you would like to talk to your dentist about the procedure, it is called the "palatal press and roll anesthesia technique."
