Earrings for your Teeth

Yesterday during dinner, Anna brought up an interesting question. She was asking if we knew how some people had earrings in their teeth. Ron and I had no idea what she was talking about but then I asked her if she meant fillings. I explained that fillings were what the dentist gave you to "fill in" a cavity. She said this was not what she meant. She wanted to know why some people have earrings in their teeth. I asked her where she had seen this before. She said our next door neighbor Will (who is in 8th grade) had earrings in his teeth. Now I know Will and I KNOW he does not have earrings in or on his teeth so I said once again that they must be fillings. Anna was insistent that they were not. I was starting to get frustrated with her until I realized that Will has braces .....and that was what Anna thought were earrings on your teeth.
