Summary

This study looks at whether taking a 600 mg dose of gabapentin two hours before wisdom tooth surgery can lower pain and the amount of opioid painkillers needed afterward. About 98 adults will be randomly assigned to receive either gabapentin or a placebo. Researchers will track pain levels and opioid use for up to 72 hours after the procedure.
