An oral hygiene system, the system comprising: an oral hygiene device (1, 1002) including a handle and a head; a camera; a display device; one or more processors; and a memory device storing instructions that, when executed by at least one of the one or more processors cause the oral hygiene system to: capture an image of a user using the camera; display, on the display device, the image of the user and a representation of at least a portion of a set of teeth of the user; overlay an indicium (1131, 1132, 1133) on the representation such that the indicium (1131, 1132, 1133) is associated with a first section of the representation; responsive to a determination, via at least one of the one or more processors, that the head of the oral hygiene device (1, 1002) is positioned directly adjacent to a first section of the set of teeth that corresponds to the first section of the representation for at least a predetermined amount of time, causing the indicium (1131, 1132, 1133) to be removed from the display; characterized in that the instructions, when executed by at least one of the one or more processors cause the oral hygiene system to display a selectable item on the display device, the selectable item being positioned at a first location within a coordinate system, the first location within the coordinate system being associated with a location in a volumetric space generally in front of the display device; and responsive to a determination, via the camera, that the head of the oral hygiene device (1, 1002) is positioned within a predetermined distance of the location in the volumetric space associated with the first location in the coordinate system for a predetermined amount of time, receive a selection of the selectable item and a graphic associated with the selectable item being overlaid on the image of the user on the display device in response to receiving selection of the selectable item. an oral hygiene device (1, 1002) including a handle and a head;
