Using the finite-element method, the stress–strain state of a tooth crown with a caries cavity acted upon by a vertical force is simulated. The tooth crown is modeled by a two-layer cylinder with outer enamel layer and inner dentinal layer. The effect of the location and geometry of the caries cavity and the mechanical properties of the enamel and dentin on the load-bearing capacity of the tooth crown is analyzed. It is shown that an increase in the length and depth of the cavity in the tooth crown leads to an increase in the stress intensity in the crown layers. The stress intensity peaks in the enamel layer near the walls of the caries cavities located near the tooth neck.
