About this trial

Nonsteroidal anti-inflammatory drugs (NSAIDs), like ibuprofen, are recommended as first-line treatment for post-surgical dental pain. However, there is variability in analgesic response, and some patients require supplemental opioids for adequate pain relief. The goal of this study is to identify the factors that contribute to the need for opioid after third molar extraction to help limit unnecessary opioid prescriptions in patients who will have good pain relief with ibuprofen alone.
