<p>A dental brush assembly includes an elongate handle having first and second coupling ends sized and shaped to couple with at least a first detachable dental brush. The first coupling end is at a first angle relative to a handle longitudinal axis and the second coupling end is at a second different angle relative to the handle longitudinal axis. The first coupling end includes first and second brush facing surfaces. The second coupling end includes third and fourth brush facing surfaces. The first detachable dental brush includes a directional brush surface and a brush end complementary to the first, second, third and fourth brush facing surfaces. The directional brush surface is directed in first, second, third or fourth non-identical orientations relative to the handle longitudinal axis depending on which brush facing surface the first detachable dental brush is oriented with.</p> |
