For some patients, sensitivity and discomfort follow vital tooth bleaching. Clinical observations, however, suggest these are reversible episodes with no irreversible long-term effects. Using milder peroxide formulations or gels diminishes postoperative discomfort. The author recommends careful treatment when patients have large restorations, cervical erosion or enamel cracks. Fluoride treatment, sealing restorations and premedication may lessen discomfort.
对一些患者来说，活髓牙漂白后会出现敏感和不适。然而，临床观察表明，这些都是可逆性情况，不会产生不可逆的长期影响。使用较温和的过氧化物配方或凝胶可减少术后不适。作者建议，当患者有大面积修复体、颈部侵蚀或牙釉质裂纹时，应谨慎治疗。进行氟化物治疗、封闭修复体和术前用药可能会减轻不适。
