Toother (2019)

After an avoidable series of root canals, HARRIS, an unemployed 29-year old, vows to his wife, LIZ, that he will begin to take better care of his teeth. But when she leaves him alone for a weekend, he becomes obsessed with a conspiracy theory: the cure for tooth decay exits, and is being withheld from the public by greedy corporations in the oral hygiene industry aka "BIG DENTAL." The more he pieces things together, the more determined he becomes to uncover the truth, if not for the good of the world, at least for his own sanity.
