N2 - In order to detect dental diseases, the current numerical study proposes a novel multilayer surface plasmon resonance (SPR) sensor structure. Changes in the refractive index (RI) of the sensing medium (SM) can be detected by the proposed sensor. The proposed sensor has been implemented using copper (Cu), molybdenum ditelluride (MoTe2), and black phosphorus (BP) layers over the SF11 prism. Performance metrics such as sensitivity (S), detection accuracy (DA), figure of merit (FoM), and penetration depth (PD) are measured. Long-range RI of SM (1.33–1.631) yields the sensitivity of 106.4°/RIU with remarkable minimum reflectivity and a 3*BP layer. The maximum sensitivity of 110.27°/RIU is obtained by taking four times the BP layers. We also have an analysis of the cementum, dentin, and enamel layers of human teeth. In terms of sensitivity, DA, FoM, and PD, the suggested sensor shows encouraging results, paving the way for future advancements in plasmonic sensing technology. Moving forward, several key research avenues can be investigated to improve sensor performance and expand its applications.
