牙齿修复是人们口腔健康需求的重要组成部分，金属类修复材料因其力学性能优异而一度被广泛应用。然而，口腔中的复杂环境为其带来了挑战，不同金属材料之间的电位差及唾液中电解质的存在，可能促使其形成微型原电池，从而引发电化学腐蚀。本文以生动有趣的方式深入探讨口腔内金牙修复体与银汞合金充填体补牙形成原电池的现象，将专业的电化学原理和口腔医学知识巧妙融合于生活场景，详细剖析金属修复体在口腔中发生的电化学反应过程及其机制、探讨其对口腔健康及修复体稳定性的潜在影响，同时介绍了复合树脂等非金属材料在消除电化学反应方面的优势，为口腔医学与电化学的交叉研究提供兼具科学性和趣味性的科普内容，助力读者提升对口腔健康背后化学问题的认知。
