When Gluma is applied in vivo, two reactions occur: first, GA reacts with part of the serum albumin in dentinal fluid, which induces a precipitation of serum albumin; and, second, the reaction of GA with serum albumin forms dihydropyridinium, whose disproportionation gives rise to free radicals, and the free radicals induce the polymerization of HEMA.

首次提出Gluma的脱敏机理为：当Gluma涂在过敏的牙本质上时，首先戊二醛交联牙本质液中的血清蛋白并产生沉淀；同时戊二醛与血清蛋白的反应产生二氢吡啶盐，它发生歧化反应，歧化过程中会有自由基产生，从而引发HEMA 聚合，生成另外一部分沉淀，这两部分沉淀共同堵住牙本质小管，起到了脱敏作用。
