A comprehensive and sensuous oral cleaner (10A, 10B, 10C, and 10D) is disclosed to automate and modernize all necessary oral hygiene. The cleaner comprises a power driver (12, 12B, 12C, 12D) that can selectively power-drive a replaceable flosser attachment (13, 14, 15, 17), a replaceable synergistic multi-motion toothbrush attachment (29), and an anti-halitosis attachment (81). The driver also power-drives scent from fragrance sources (68, 24) in the attachments for sensuous ambiance while oral cleaning. The toothbrush attachment is detachably connectable to the power driver for imparting plural motions of a long-bristle toothbrush (77). These actions serve for driving long toothbrush bristles to longitudinally penetrate interdentally for power-brushing interdental contours. In the flosser attachment, a floss span is power-driven in plural motions to efficiently remove plaque as the moving span follows, scrubs, and polishes interdental contours between adjacent teeth. Three embodiments of the flosser attachment use warmed power-driven air to dry the used floss for odor-free storage until replacement of the attachment. Alternatively, two of the flosser attachment embodiments feature an antimicrobial (68) that coats the used floss to inhibit microbial activity. The power-driven anti-halitosis attachment drives a multi-bladed tongue scraper (89, 89B) along with pressurized air to neutralize causal anaerobic tongue bacteria.
