Waterless toothbrush doesn't make a splash

KPK Products

The bresh brush, for water-free brushing.

Do you find yourself stuck in places where you're about to have an all-important-meeting, need to brush the ivories but there isn't any water? You can brush-on-the-run and save H2O with waterless toothbrushes — as strange as they might sound.

Technology meets clean teeth in these creations. Among them, the "bresh" from KPK Products, which is dubbed as "100 percent biodegradable and recyclable."

"Simply push on the flexible cap, and toothpaste flows into the bristles. The cap contains a non-fluoride toothpaste with all natural Xylitol," KPK says.

UTRM

The Freedom Brush, uses cartridges called liquid dentrifices, for brushing on the go, sans water.

Xylitol is "widely used as a sugar substitute and in 'sugar-free' chewing gums, mints, and other candies," says WebMD on its site. "Xylitol tastes sweet but, unlike sugar, it is not converted in the mouth to acids that cause tooth decay. It reduces levels of decay-causing bacteria in saliva and also acts against some bacteria that cause ear infections."

The bresh toothbrushes, which come individually wrapped, are $2.95 for a pack of 5, $5.49 for a pack of 10, and $10.99 for a pack of 20.

Another, the $12.99 Freedom Toothbrush, is from UTRM, a dental health and green technology company. UTRM's toothbrush is for ongoing use, not meant to be disposable like the bresh.

UTRM's toothbrush uses "liquid dentifrice in replaceable cartridges incorporated in the handle with a pump mechanism, so toothpaste is no longer required to brush, allowing the user to brush virtually anywhere at any time with no water required."

A replacement liquid dentrice costs $2.49; you can replace the brush's head, when needed, at a cost of $4.99.

The company says its goal is to help "avoid depleting our world's precious water supply," and boasts that "by eliminating the need for water, our dental products save millions of gallons of water annually, and present a safe guarantee to dental hygiene in unsanitary conditions."

There's no rinsing needed with these brushes: you just use them and go on about your business.

For some of us, who schlep too many things in our purses or briefcases already, a waterless toothbrush might be one more item that gets lost in our mix of cell phones, iPods, keys, and other miscellaneous mishegas we carry with us. But for those who want that quick brush on the go, this kind of product could be a helpmate you may never want to be without.
