I absolutely hate flossing and never do it. I bought one of those dental pressure washer things to compensate, and I love it. It blasts piles of food gunk out from between your teeth, way better than flossing will ever hope to accomplish, as well as flushes under the gumline. Plus, it takes less time than flossing. The dental workers have commented that I floss very well, joke's on them. ;-)

Electric toothbrushes are also great for keeping your teeth very clean, and can penetrate between your teeth depending on the design.
