Not medical advice: Waterpik should be used before flossing and brushing, as advised by dental care website, DrAnkoHsiao.com.
The Waterpik loosens food and plaque before brushing and should be used on the lower water pressure settings so the gum tissue is not excessively irritated. The use of a Waterpik does not take the place of good toothbrushing.
If you are looking for an effective alternative to manual or string floss, you can floss with water instead of string! See how to floss with a Waterpik Water Flosser here.
Toothbrushing is such an ingrained habit, few people think twice about it. But as with any habit, you can get sloppy, and that can lead to cavities and gum disease. Read WebMD's 10 Toothbrushing Mistakes: How to Brush Teeth the Right Way.
