A combination of acetaminophen and ibuprofen works just as well as a low dose of opioids in relieving pain in both men and women after wisdom tooth removal, according to a new study in JAMA Network Open. 

The research builds on a previous study of over 1,800 patients, which compared the effectiveness of 400 mg of ibuprofen and 500 mg of acetaminophen to 5 mg of hydrocodone and 300 mg of acetaminophen in the first three days after surgery. That dose of hydrocodone is the equivalent of 5 morphine milligram equivalents (MME).

“We wanted to determine whether the pain medication’s effects were consistent in males and females separately,” lead author Janine Fredericks Younger, DMD, an associate professor at Rutgers School of Dental Medicine, said in a press release.

 “And what we found is that in both subgroups (males and females), the non-opioid was superior for that first day and night, and then no worse than the opioid for the rest of the post-op period.”

Researchers performed a gender-specific analysis because women report higher pain levels after surgery, raising questions about whether pain medications work differently for each sex.

“There’s obviously different biological mechanisms, different hormones involved,” said Cecile Feldman, DMD, Dean of Rutgers School of Dental Medicine and senior author of both studies. “But results confirm that the analgesic effect for both groups is the same.”

Pain levels were low whether patients took acetaminophen-ibuprofen or the hydrocondone-acetaminophen combination. Pain ratings over three days were slightly lower for female patients taking non-opioids than those on the low dose of hydrocodone (2.83 vs 2.98). The same was true for male patients (2.24 vs 2.37).

Patient satisfaction and sleep quality were also slightly better in the non-opioid group, which also experienced less pain interference with daily activities. 

“The results actually came in even stronger than we thought they would,” Feldman said. “We expected to find the non-opioid to be non-inferior, so that at least it was no worse than opioids. We were surprised to see that it was actually superior.”

Wisdom tooth extraction was often the first exposure that a patient had to prescription opioids, although their use after dental procedures has declined in recent years as fears grew about opioid addiction.

Last year the American Dental Association (ADA) released new guidelines recommending that nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen be taken alone or in combination with acetaminophen as first-line treatments for acute dental pain in adults and adolescents aged 12 and older. 

NSAIDs reduce inflammation and pain, while acetaminophen reduces pain and fever. Taking the two together is believed to boost their analgesic effect. 

The ADA says opioids should only be used when NSAIDs and acetaminophen don’t relieve pain enough or when NSAIDs are contradicted due to health issues, such as a patient having cardiovascular problems or a bleeding ulcer.     

The risk of long-term opioid use after a tooth extraction is relatively rare. A large study of over 70,000 teens and young adults who had their wisdom teeth removed found that only 1.3% were  prescribed opioids long-term after their initial prescription by a dentist. 

Wisdom tooth extraction is performed about 3.5 million times a year in the United States, 

“We feel pretty confident in saying that opioids should not be prescribed routinely for dental procedures,” Feldman said. “Our non-opioid combination really should be the analgesic choice.”
