Today, more than 50 studies have been conducted on the Waterpik dental water jet in over 25 independent and university-based research centers.  Research into the physics of the product has shown that pulsation appears key in the dental water jet since that is what helps clear bacteria and debris.  Today's Waterpik dental water jet oral irrigator is based upon the same principle and design as the original model – a powerful miniature pump sends a pulsating jet of water through a plastic syringe-like tip to clean the teeth (sweeping away debris from over, around and between teeth, and under the gumline) and stimulate the gum tissues.

Today's dental water jet is recognized as a product ahead of its time. The dental water jet's unique ability to disrupt bacteria that contributes to gum disease is now recognized by dental professionals; so much so that the Waterpik dental water jet is the dentist's #1 choice. Over the years Water Pik, Inc. has continued to work closely with dental professionals and consumers to develop and introduce products and accessories that help people improve their oral health.

After missing from the NZ market for some years, ToothShop now supplies the official licensed NZ model WaterPik Dental Water Jets with both the countertop and cordless models available as well as replacement tips.
