A new numbing chemical, similar to lidocaine, called Exparel, slowly releases a pain blocking chemical for up to 96 hours. The chemical is encased in fat-like suspension or lipid, which then gets injected into the surgical area. This pain-blocker then slowly releases medication, right at the site of pain.
Researchers first developed Exparel for other types of surgery. After testing with oral surgery, researchers discovered Exparel in most cases completely eliminated the need for patients to take prescriptions opioid pain medications. So for those needing your wisdom teeth out, or anticipating gum surgery, this new pain treatment protocol might be a great option.
