Abstract: An oral hygiene device includes an anti-microbial compound which is applied to tissues in the mouth to freshen breath or otherwise inhibit the growth of bacteria. In one embodiment, the anti-microbial compound is combined with a tongue scraper to remove bacteria and other contaminants from the tongue prior to application of the anti-microbial compound. The anti-microbial compound typically includes a anti-microbial agent and a binding and tactifying agent, and can have flavoring, sweeteners, and abrasives added.

Abstract: Pre-shaped, non-custom dental trays are either preloaded with a dental treatment composition (e.g., in the form of a gel) or filled with a dental treatment composition just prior to placement over a person's teeth. The pre-shaped dental tray is thin and flexible, which allows it to be placed over a person's teeth and then approximately conform to the person's teeth. The pre-shaped, non-custom dental trays can therefore perform similar to a customized tray but without having to go through the more lengthy customization procedure. According to one embodiment, a pre-shaped dental tray can be pre-loaded with a dental treatment composition and stored within a sealed packaging container. Alternatively, it can be sold by itself or in combination with a treatment composition that a user can load into the dental tray. The tray can be manufactured by vacuum forming polymeric sheet material over a template.
