At least once a day. To give your teeth a good flossing, spend at least two or three minutes. You may prefer a prethreaded flosser or floss holder, which often looks like a little hacksaw. Flossers are handy for people with limited dexterity, for those who are just beginning to floss, or for caretakers who are flossing someone else's teeth. In a pinch, toothpicks are effective at removing food between teeth, but for daily cleaning of plaque between teeth, floss is recommended.
Toothpicks come round and flat, narrow and thick.
When you use a toothpick, don't press too hard as you can break off the end and lodge it in your gums. Don't use waterpicks as a substitute for toothbrushing and flossing. But they are effective around orthodontic braces that retain food in areas a toothbrush cannot reach. However, they do not remove plaque. Waterpicks are frequently recommended for persons with gum disease when recommended by your dentist.
