Color indicating chewing gum compositions comprising one or more color compounds are provided. The compositions demonstrate a visual color or shade change from start of chewing to the end of chewing and provide oral health benefits. Methods of producing a color changing chewing gum are also provided.

The present invention relates to a method for a chewing-gum based mitigation of virus-related disease spread and pre-immunity activation based on disruption of syntrophic methanogenic processes in the oral-, shared oronasal and orotracheal microbiome. The invention provides a chewing gum composition comprising a methylotrophic yeast, preferably Komagataella phaffii; a plant lectin, preferably phytohaemagglutinin; and/or iron particles, preferably zero-valent iron particles.

The present invention is directed to a confectionery capable of imparting oral care benefits to an end-user, the confectionery containing: a first sweetener; an optional second sweetener, a flavorant and optionally a functional active ingredient for promoting tooth mineralization, wherein the confectionery is substantially sugar-free. The present invention is also directed to a method of imparting oral care benefits to a consumer involving inserting the above-described confectionery into a consumer's mouth and allowing the confectionery to dissolve in the consumer's mouth over a prolonged period of time.

The present invention relates to a use of 3,6-anhydro-L-galactose for preventing dental caries. More specifically, 3,6-anhydro-L-galactose inhibits the growth of oral microorganisms and exhibits anti-caries activity to inhibit the production of acids caused by the consumption of a carbon source by the oral microorganisms. Thus, 3,6-anhydro-L-galactose can be used in pharmaceuticals, food products, oral hygiene preparations, etc. for preventing, ameliorating or treating oral diseases caused by oral microorganisms, such as dental caries, gingivitis, periodontitis, oral mucosal ulcer, halitosis or xerostomia.
