A temporary dental cement composition temporarily affixes a dental prosthesis or appliance to a tooth or other dental substrate. The dental cement includes a mixture of: (i) an ion leaching agent; (ii) polycarboxylic acid; (iii) sugar; and (iv) water. The sugar is added in a sufficient amount that the ion leaching agent and polycarboxylic acid form a hardenable adhesive having an adhesive matrix which forms a relatively weak, temporary bond, as opposed to a permanent bond. The temporary cement composition is compatible with subsequent deposition of typical bonding materials, such as resin luting agents as well as non-resin permanent cements.

[ What is claimed and desired to be secured by United States Letters Patent is:] [1.]1. A method for forming a temporary dental composition, the method comprising:mixing (i) at least one ion leaching agent;(ii) at least one polycarboxylic acid;(iii) at least one sugar selected from the group consisting of five-carbon sugars, six-carbon sugars, and mixtures and derivatives thereof; and(iv) water to form a temporary dental composition which hardens in a manner such that it can be removed when desired,wherein the at least one sugar is present in an amount greater than 0.5% by weight of the temporary dental composition.
