| Character Information
Ludacris is an American rapper.
Ludacris is the main protagonist in Menace Tooth Society, an educational film for kids about dental care. Lisa watched this film when the Simpson family went for a visit to the dentist. The film consists in Ludacris portraying a toothpaste tub named "Luda-Crest" fighting various dental diseases such as tooth decay, gum disease, gingivitis, periodontitis and plaque with the help of a toothbrush and dental floss. The film is accompanied by the rap "Luda-Crest Wisdom".
Apparently, the film was supposed to be aired only one time in Canada, but the Springfield Dentists used the film without Ludacris' permission.
