Dentists especially recommend them for braces, implants, and anyone who simply won't use string floss.

For many people, practically yes — the best floss is the one you'll use daily. Some dentists still recommend string for the tightest contacts, but a water flosser used every day beats string floss used twice a month by a wide margin.

Countertop wins on pressure range and reservoir capacity; cordless wins on travel, shower use, and small bathrooms. If it's your primary flossing tool and you have the counter space, go countertop. Frequent travellers should add or substitute a cordless.

Once daily, ideally before brushing at night so fluoride toothpaste reaches freshly cleaned gaps. Use warm water on a comfortable pressure, aim the tip just above the gumline at 90 degrees, and trace along it pausing briefly between each tooth.
