An apparatus for imparting low amplitude vibrations to at least one tooth in a human head having a cochlea to facilitate hearing via a dental bone conduction pathway includes an extraoral transmitter, a band at least substantially surrounding and adhesively secured to at least one tooth, and a receiver assembly. The transmitter is configured to detect ambient sounds, and to generate and wirelessly transmit audio signals corresponding to the detected ambient sounds. The receiver assembly is removably coupleable to the band and configured to receive the audio signals from the transmitter, and to transduce the audio signals into vibrations that are conducted to the cochlea via the dental bone conduction pathway.
