Provided are methods and compositions relating to a dental composition more specifically to prepare the damaged dentin of the tooth for animals and pets such as canine, feline and members of the taxonomic family Equidae prior to repair. The dental compositions include a bioactive glass and a non-aqueous solvent comprising an alcohol, anti-inflammatory and anti-pain reliever.

Fibers, for example fiberglass fibers, are added to dental stone powders to provide for reinforced dental stones. Dental stones are made by combining dry components, including binder and fiber glass, adding water to the resulting mixture and setting the mixture in a dental mold. The dental stones are reinforced by the fibers, and allow for reduced breaking or chipping during handling.
