According to Dr DiGiulio, a Bend dentist, one of the problems with regular flossing methods is that it can be quite difficult to reach some areas of the mouth. The back teeth in particular are hard to get at, especially if you have large fingers and hands. Remember that teeth have 5 surfaces and the brush can only reach 3. Using a Hydro Floss Oral Irrigator eliminates this type of problem because the long, angled jet tips make it very easy to clean around every single tooth. From her Bend dental office, Dr DiGiulio says that It only takes a few practice runs to get used to handling the jet tips, and after that, giving your mouth a thorough cleaning becomes a breeze. This type of hygiene can also help prevent serious cardiovascular disease in that there s a link between gum disease and heart attack and stroke.
