"Dentist" is the twenty-first episode of the sixth season of the American animated television series Adventure Time.

The episode debuted on November 28, 2014 and guest stars Lucy Lawless, Collin Dean, and Andy Daly.

In this episode, Finn has a tooth ache, so he visits the dentist, a group of ants led by General Tarsal (voiced by Lucy Lawless), who provide dental care in exchange for a tour of duty.

After one of Finn's teeth starts to ache, he agrees to "go [sic] Dentist", which is later revealed to not be a single doctor of dental surgery, but a colony of ants led by Gen. Tarsal (voiced by Lucy Lawless).

In the resulting melee, Tiffany is apparently killed by the Queen Worm, and Finn shatters all of his teeth, but they are promptly fixed by the ants.

"[9] The episode caused a minor controversy on the Internet due to the naming of Andy Daly's character "Lt. Gamergate".

[11] Co-executive producer Adam Muto later reiterated this claim, noting that the episode was written six months prior to its airing, thus predating the Gamergate controversy.

Carolyn Cox of The Mary Sue later commented on the issue, noting: "Considering how far in advance of their air date Adventure Time episodes are written, it's an indication of both the Internet's weariness with the movement and Gamergaters' disproportionate obsession with the cause that fans immediately assumed the episode was referencing the current climate in gaming culture.
