Sonitus Medica of San Mateo, California has received FDA clearance for SoundBite, a dental hearing aid for people with deafness in one ear. The system works much like a cochlear implant, except for the implantation. A behind the ear device wirelessly transmits audio from the affected ear to a little receiver attached to a tooth that resonates the teeth, that in turn stimulate both cochlea. The removable In-The-Mouth (ITM) device showed no long-term effects on dental or periodontal soft or hard tissues and was determined to be safe for long-term dental wear. The device was worn on patients` natural teeth, as well as on those with fillings, restorations, crowns, root canals, and dental implants.
