Happened to me nearly 40 years ago on my baby teeth. My mother finally had enough and took me for a second opinion and the next dentist found no problems. It’s given me 40 years of dental anxiety so bad that I have to go to a specialist that deals with it. The only time I had to have work done there, they drugged me to the gills.
A few years back, I handed out candy for friends while they took their kids around the neighborhood, and a group of kids jokingly asked for potatoes. I obliged and grabbed them each a potato from the pantry.
When my friends came back, the potato house was apparently the talk of the kids in the neighborhood.
