A fiber-reinforced composite (FRC) dentin anchor is disclosed comprising a coronal portion, to which a tooth restorative material may be secured, and a dentinal portion, adapted to be received in a pre-drilled hole in tooth dentin. The dentinal portion may be adapted to chemically bond to the tooth without the use of threads and the coronal portion may be adapted to chemically bond to a tooth restoration without the use of additional adhesives. The dental anchor may includes an intermediate portion having a shape and size that is different from the shape and size of the dentinal portion and the coronal portions and be adapted to be received entirely or partially within the pre-drilled hole in the tooth dentin. The modulus of elasticity of the dentin anchor may approximate the modulus of elasticity of tooth dentin.
