Photothermal Effect and Biomineralization of Black Phosphorus Nanosheet‐Composited Hydrogel Boosts Synergistic Treatment of Dentin Hypersensitivity (Adv. Sci. 9/2025)

Dentin‐Desensitized Hydrogel In article number 2412561, Congxiao Zhang, Jianxun Ding, and colleagues introduce an innovative black phosphorus nanosheet‐composited methacrylate gelatin hydrogel for treating dentin hypersensitivity. This hydrogel harnesses a synergistic photothermal effect and biomineralization to effectively occlude dentinal tubules and alleviate tooth sensitivity, showcasing its potential as a highly effective desensitizing agent.
