Unique abrasive and / or thickening materials that are in situ generated compositions of precipitated silicas and silica gels are provided. Such compositions exhibit different beneficial characteristics depending on the structure of the composite in situ generated material. With low structured composites (as measured via linseed oil absorption levels from 40 to 100 ml oil absorbed / 100 g composite), simultaneously high pellicle film cleaning properties and moderate dentin abrasion levels are possible in order to accord the user a dentifrice that effectively cleans tooth surfaces without detrimentally abrading such surfaces. Increased amounts of high structure composite materials tend to accord greater viscosity build and thickening benefits together with such desirable abrasion and cleaning properties, albeit to a lesser extent than for the low structure types. Thus, mid-range cleaning materials will exhibit oil absorption levels from an excess of 100 to 150, and high thickening / low abrasion composite exhibit oil absorption properties in excess of 150. Such an in situ, simultaneously produced precipitated silica / silica gel combination provides such unexpectedly effective low abrasion and high cleaning capability and different thickening characteristics as compared to physical mixtures of such components. Encompassed within this invention is a unique method for making such gel / precipitated silica composite materials for such a purpose, as well as the different materials within the structure ranges described above and dentifrices comprising such.

This portable appliance can be used to clean teeth by liquid (water or solution) containing dissolved ozone, which is a potent oxidizer and germ killer. Preferably, its cleaning action is enhanced by pulsations of the liquid stream. The dissolved ozone can reduce or eliminate gingivitis, gum bleeding, bad breath, teeth stains, and harmful oral bacteria. This appliance can also be used for nasal irrigation for sinusitis treatment and for ear irrigation, eye care, and general cleaning. Additionally, since its output pump is independent of the ozone dissolving system, the ozone dissolving system can be configured as an add on device for an oral irrigator such as a Water Pik™ manufactured by WaterPik Technologies, Inc. In this configuration, the ozonated liquid is delivered by either gravity or pumped flow, to the original reservoir connection with the irrigator serving as the delivery portion of this invention.
