Solved my gum line issue in two days
I brush and floss religiously.  I was recently left with swollen gums in one area after a poorly executed dental procedure.  I ordered this Waterpik in hopes of solving the problem without a return to the dentist for what I thought would be gum surgery. After two days of using the Waterpik the swelling is down.  I can only assume food had gotten stuck under my gums in that area.  This Waterpik came with a brush/pik combination and a gum pik plus a couple more.  I just tried the general Waterpik and I'm loving it.  So easy I do a quick pass every time I brush my teeth.
