text: do oral "waterpick" products really work at dental/gum problems, or are they more hype?   they really do work! they stimulate the gum tissue and toughen it against periodontal disease, and they are also excellent for removing food particles. try it- brush your teeth, then use a water pick. you'll see the food it dislodges. one tip- when you first begin, use a very gentle setting, or else you can cause gum injury/bleeding. as your gums strengthen, you can increase the pressure.
