An improved oral-hygiene apparatus, for example a toothbrush, includes a handle configured to resist rolling and angled to maintain the head off a surface when idle. In addition, the apparatus includes recessed tongue-cleaner on the head, opposite the bristles. The tongue-cleaner features a rounded tongue-curette scrape edge and smooth curette base. This design allows omni-directional travel and effectively scrapes and cleans the tongue and inner cheek. The present invention is economical to produce and does not increase the overall thickness of the instrument head.
