The invention provides polymerizable dental, compounds, compositions, including the compounds and products for mixing the compositions and methods of using the compositions. Aryl acid compounds are provided in accordance with the invention. The compositions include at least one polymerizable aryl acid compound, an effective amount of a polymerization initiator, and at least 10 percent by weight of ceramic, metal and/or metal oxide filler particles having a particle size less than 500 microns. The dental products of the invention include a polymerizable composition in an enclosure having at least two chambers separated by a wall adapted to be ruptured prior to or during mixing of the composition. Compositions of the invention are preferred for use in these enclosures. Core build up material including a polymerizable acid containing compound is used to support dental crowns and adhere them to teeth in accordance with the invention.
