You left out the easiest and most effective home remedy. With your favorite teeth whitening toothpaste; dip your toothbrush with toothpaste into a box of baking soda then simply brush your teeth.
If you want the benefits of bacteria killing peroxide you can mix some with some mouth wash and water in your Water Pic to flush out junk caught between your teeth and gums but set it on the lowest power setting because it can actually slowly separate your gums from your teeth. A light flush to get some solution in there is all you need. To clean between the teeth with the Water Pic; hold it at a 90 degree angle as you move it across your teeth.
The first time you use a Water Pic, if you haven’t just flossed, might surprise you on the particles of food it flushes out. It sure surprised me anyway.
Just got a Water Pik last week, and am anxious to see if dentist has any feedback at my next checkup in about 6 weeks.
