There is provided a dental composition for relieving dentin hypersensitivity, which occludes dentinal tubules having an opening on the surface of dentin to relieve dentin hypersensitivity thereby to give an immediate relieving effect and to maintain the relieving effect for a long time. The dental composition for relieving dentin hypersensitivity, which comprises (A) a low molecular weight compound which can produce a precipitate which is hardly soluble in water when it reacts with a calcium compound, or which comprises the above component (A), (B) a calcium compound and/or (C) an aqueous polymer emulsion having a particle size smaller than that of a dentinal tubule and forming an agglomerate or a hardly soluble gel larger than the diameter of a dentinal tubule when it reacts with a calcium compound.

This invention is a solid breath cleansing confection and a method for its manufacture which comprises an ingestibly acceptable alpha-amylase of between 1-8 SKB units of alpha-amylase which is in sufficient amount to degrade starch. The alpha-amylase may be from any source but in the currently preferred embodiment it is a fungal alpha-amylase. The confection may further comprise a solid comestible confectionary base containing flavoring and a sweetener which does not promote tooth decay. The sweeteners may be natural or artificial and in the currently preferred embodiment the sweetener is sorbitol. The confectionary base may be a gum or lozenge base and the flavoring may be natural or artificial flavoring, for example, mint flavoring such as natural or artificial wintergreen or natural or artificial spearmint.
