The game uses the camera of the device it is being played on for an augmented reality system, which is used to play the game. Bacteria appear in the player's mouth and attack Pokémon. By brushing their teeth, the player is able to rescue the Pokémon. At the end, the game allows the player to attempt to catch one of the Pokémon.[2] After catching Pokémon, they can be leveled up.[3] The player may also earn other rewards, such as hats and stickers.[2] The time spent brushing can be set between one and three minutes.[4] Each day, the game can notify users up to three times to remind them to brush their teeth.[5]
The game will sometimes fail to recognize a player's brushing. According to The Pokémon Company, a colorful toothbrush in a bright room usually solves the problem.[6]
