Today I went to the dentist for a broken filling & a lot of pain. I haven’t gone to the dentist in about 2 years & was not looking forward to the work to be done. When it came time to be numb, I was shown something new & told the vibrations would help with the numbing. Once it was done I was asked if I felt the shot & I can honestly say I had no idea I even got a shot! I never felt it, just felt & heard the vibrations. That numbing shot is usually the worst part but not this time. I’m glad to use this anytime I need dental work!
