I am looking into getting an oral irrigator as I have read many good things about them being even better than flossing because the water stream can get into places where floss can't and it is gentle on the gums, where floss can be rough sometimes. Anyone have experience with these tools and have a recommendation for a brand. I've looked at Amazon and the price range is huge, so I'd like some opinions if possible to help me decide if I should really spend a whole lot or just get one of the less expensive ones.
