Dental materials are provided comprising Component i), which is a hydrogen bondable compound that is a polymer having a molecular weight greater than about 10,000, and Component ii), which is a hydrogen bondable bridging compound. One of Components i) and ii) contains 2 or more hydrogen-bond donor sites per compound, and the other of Components i) or ii) contains 2 or more hydrogen-bond acceptor sites per compound, which hydrogen-bond acceptor sites are not capable of also acting as hydrogen-bond donor sites. Components i) and ii) are present in an amount sufficient to exhibit at least 10% higher Relative Viscosity, and optionally at least one of i) or ii) is polymerizable. If the material contains any compounds having only one hydrogen-bond donor site or hydrogen-bond acceptor site per compound, the ratio of hydrogen-bond donor sites on compounds having only one hydrogen-bond donor site to hydrogen-bond donor sites on compounds having 2 or more hydrogen-bond donor sites per compound is less than 0.25, and the ratio of hydrogen-bond acceptor sites on compounds having only one hydrogen-bond acceptor site to hydrogen-bond acceptor sites on compounds having 2 or more hydrogen-bond acceptor sites per compound is less than 0.25.
