TripleDent Gum is a brand of gum seen in Disney/Pixar's Inside Out, whose jingle is used as a running gag throughout the film. Anger gets annoyed whenever he hears it. During the end credits scenes, Gary's emotions, who all have the form of Anger, attempt to find their "happy place" by watching a happy memory. Unfortunately, that happy memory turns out to be the jingle, which ends up irritating the Emotions even more. The voices in the jingle are sung by Nick Pitera and Andrea Datzman.
Will make you smile
It lasts a while
Will help you, mister
To punch bad breath right in the kisser
TripleDent Gum may be inspired by Trident Gum, which Pixar had produced a commercial for prior to making Toy Story. The commercial bears no resemblance to TripleDent Gum, though.
TripleDent Gum appears in Cars 3 as the sponsor for two of the Piston Cup racers, Terry Kargas and Cam Spinner.
