Paste comprises at least one radically polymerizable monomer, at least one polymer, which is soluble in at least one radically polymerizable monomer, and at least one filler, which is insoluble or sparingly soluble in at least one radically polymerizable monomer. The filler is a particulate inorganic filler with a Brunauer, Emmett and Teller (BET) surface area of at least 40 m 2>；/g. An independent claim is also included for a kit comprising a paste A and paste B1, where (i) the paste A comprises (a1) at least one radically polymerizable monomer, (a2) at least one polymer, which is soluble in (a1), and (a3) a polymerization initiator, (ii) the paste B1 comprises (b1) at least one radically polymerizable monomer, (b2) at least one polymer, which is soluble in (b1), and (b3) a polymerization accelerator, and (iii) at least one of the pastes A and B1 comprises filler, which is insoluble or sparingly soluble in (b1), as the component (a4) or (b4).
