"Dentist" debuted on November 28, 2014 on
Cartoon Network. The episode was seen by 1.398 million viewers, and received a 0.3 rating in the 18–49 demographic. This means it was seen by 0.3 percent of all 18- to 49-year-olds watching television at the time of the episode's airing. The episode first saw physical release as part of the 2016 compilation
DVD Card Wars. Oliver Sava of
The A.V. Club awarded the episode a "B−", calling it "disappointing" and "disjointed". The episode caused a minor controversy on the
Internet due to the naming of Andy Daly's character "Lt. Gamergate". Some fans interpreted this name to be a reference to the 2014
Gamergate controversy. 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." ==Explanatory notes==
