Short Guide to Water Flossers

Oral hygiene is something no one should neglect as it can not only lead to dental problems, but it can also have a negative impact on your overall health. The good news is you can take better care of your teeth yourself with the various products out there. If you want to reduce plaque, gingivitis and gum disease then water flossers are pretty much the standard items on the market these days.

If you have braces or implants, and crowns, bridges, and veneers, then again there is no going wrong with a decent water flosser. Water flossers use a pulsating jet of water that pressure sprays between your teeth and below the gum line to remove plaque and food debris.

So no more taking out the floss and doing the tedious job. It is very quick and easy to use and dislodges anything stuck between your teeth in the blink of an eye.

A Quick Review for the Waterpik Aquarius

One of the most advanced water flossers out there, the Waterpik Aquarius Water Flosser WP-660 – comes with a water control function on the handle and it is as easy as sliding it on and off. It also has a covered reservoir with a capacity of 90 (in seconds) while there is also a covered tip storage in the unit.

One of its cool key features is the new pulse-modulation technology. You get maximum plaque removal with the floss mode and enhanced gum stimulation and improved circulation with the hydro-pulse massage mode by using the one-minute timer with a 30-second pacer. It also has a pretty easy to understand LED information panel, seven water flosser tipswhile the number of pressure settings goes up to 10.

The Waterpik Aquarius has two types of heads – a normal one and a compact one. On the technical side, the cord is 53 inches and the voltage is compatible with 120VAC/60Hz (North America) outlets. It comes standard with a three-year warranty, while white is your only option for a color.
