This review looked at different ways to manage tooth sensitivity that occurs after professional bleaching. The researchers looked at several treatments, including common medications like analgesics and anti-inflammatory drugs, as well as specific treatments like potassium nitrate, fluoride, and calcium-based agents. They also looked at a light-based treatment called photobiomodulation therapy (PBMT).
The findings showed that systemic analgesics and anti-inflammatory drugs did not provide a meaningful way to prevent sensitivity. Potassium nitrate-based treatments showed small reductions in how intense the pain felt, though they were not consistent at preventing the sensitivity from starting. Calcium-based agents showed limited and low-certainty benefits. Because fluoride is often mixed with other ingredients, its specific effects were harder to determine.
Photobiomodulation therapy appeared promising for reducing the intensity of pain, but the results were limited by inconsistent study methods. Most treatments studied were better at making the pain less intense rather than preventing it from happening in the first place. Because many of these findings have low certainty or were based on varied study designs, patients should talk to their dentist to find the best treatment for their specific needs.
