Various embodiments for cleaning carious regions of a tooth are disclosed herein. For example, a dental apparatus can include a fluid platform having a chamber sized and shaped to retain fluid. The chamber can be configured to be coupled to the tooth over the carious region. A pressure wave generator having a distal end may be configured to be positioned in the chamber. The pressure wave generator may be configured to generate pressure waves in the retained fluid sufficient to clean the carious region.

An improved ultrasound apparatus and methods of use are provided, the apparatus comprising at least one ultrasound transducer electrically connected to another electrical component by a flexible electrical connection. In some embodiments, the other electrical component is a printed circuit board. In some embodiments, the flexible electrical connection may allow vertical, horizontal and/or tilting displacement of the ultrasound transducer with respect to the flexible circuit board while maintaining electrical connectivity. In some embodiments, the flexible electrical connection is capable of temporarily disconnecting when an excessive deformation force is applied and self-reconnecting after the excessive deformation force is removed.

An orthodontic remodeling device, wherein the bite plate is modified to have textured teeth and gum facing surfaces so as to provide cleaning, massaging or acupressure effect when in use.
