An oral insert, comprising:

• a base that includes a plurality of manifold holes arranged in a circle;
• a plurality of bristles located on an upper portion and a lower portion of a tray surface of the oral insert;
• a plurality of fluid nozzles located at an inner portion and an outer portion of the tray surface;
• and
• a plurality of manifolds, wherein each of the plurality of manifolds is associated with a corresponding manifold hole of the plurality of manifold holes, wherein each manifold of the plurality of manifolds is associated with a corresponding subset of the plurality of fluid nozzles, wherein the oral insert is configured to be connected to a handle, wherein fluid is provided from the handle to the oral insert via the plurality of manifold holes, wherein the handle includes a manifold disc and a manifold disc selector, wherein the manifold disc selector includes an opening and a cut-out that is opposite the opening, wherein the cut-out extends only partially through the manifold disc selector, wherein the fluid is selectively provided to the plurality of manifolds via the plurality of manifold holes as the manifold disc selector rotates.
