Dr. Polo didn’t tell me that I was going to get a shot. I wore these glasses & the chair was laid back, so I just closed my eyes & tried to relax. He had just taken an impression of my bite, so I had no idea what else he was going to do. Cindy the dental assistant used the DentalVibe, which I have never had before. Maybe I’m not like most people, I enjoyed the feeling, like a massage on my gum. Next thing Dr. Polo says just relax & I’ll be back in 4 min. . It was only a couple of minutes later that I knew he gave me an injection. Because my lip was numb. No one likes to go to the dentist, they’re afraid. They don’t want a shot. If their dentist uses Dentalvibe, it will relieve their patients anxiety.
