We see a series of different adults, all with cosmetic dental problems with their front two teeth (missing, damaged, broken, cracked, etc.), singing the following lyrics from the song: "All I Want for Christmas Is My Two Front Teeth":
All I want for Christmas is my two front teeth,
My two front teeth,
My two front teeth,
All I want for Christmas is my two front teeth,
My two front teeth,
My two front teeth,
All I want for Christmas is my two front teeth,
My two front teeth,
See my two front teeth,
Gee, if I could only have my two front teeth,
Then I could wish you: "Merry Christmas!"
(Normally this is a cute song meant to be sung by little children who are missing their two front teeth because their baby teeth have fallen out and their adult teeth have not grown in yet. But to have a series of adults singing the song would show how much more of a problem it is for adults to need two front teeth. And then the announcer would explain how and where to get dental implants.)
