Dentists can prescribe a wide range of pain medications, from over-the-counter anti-inflammatories and acetaminophen to opioids like hydrocodone and oxycodone for severe cases. Current American Dental Association guidelines make the hierarchy clear: non-opioid medications are first-line therapy for acute dental pain, and opioids should only come into play when those options fall short.
NSAIDs and Acetaminophen: The First Choice
For most dental pain, including after extractions and for temporary relief of toothaches, anti-inflammatory drugs like ibuprofen alone or combined with acetaminophen provide superior pain relief with a better safety profile than opioids. This isn’t a second-best option. NSAIDs reduce pain at its source by blocking the inflammatory process that makes your mouth throb after a procedure.
Your dentist will typically recommend a specific dosing schedule based on how much pain they expect. For moderate to severe pain, the ADA’s protocol calls for 400 to 600 mg of ibuprofen plus 500 mg of acetaminophen every six hours for the first 24 hours, then stepping down to 400 mg of ibuprofen plus 500 mg of acetaminophen as needed. In 2020, the FDA approved a fixed-dose combination tablet containing 250 mg of ibuprofen and 500 mg of acetaminophen in a single two-caplet dose, making this easier to manage.
This combination works better than either drug alone because each one blocks pain through a different mechanism. Ibuprofen targets inflammation directly, while acetaminophen works on pain signaling in the brain. Together they cover more ground than a single medication can.
When Opioids Enter the Picture
For severe pain, particularly after surgical procedures like impacted wisdom tooth removal, your dentist may prescribe an opioid alongside the ibuprofen and acetaminophen combination. Hydrocodone and oxycodone are the two most common opioids used in dental care. The ADA’s guideline for severe pain adds 10 mg of hydrocodone to the standard ibuprofen-acetaminophen combination every six hours for the first 24 to 48 hours, then drops the opioid entirely and continues with just the non-opioid pair.
That short timeline is intentional. Dental opioid prescriptions are meant to bridge you through the worst of the pain, not serve as ongoing relief. Most post-procedure dental pain peaks within the first two days and then steadily improves. If your pain isn’t getting better after 48 hours on opioids, that’s a signal something else may be going on, like an infection or dry socket, rather than a reason to refill the prescription.
Corticosteroids for Swelling and Inflammation
After more complex procedures, especially wisdom tooth surgery, your dentist may prescribe a corticosteroid like dexamethasone. This isn’t a painkiller in the traditional sense. It works by suppressing the inflammatory response that causes swelling, jaw stiffness, and the deep ache that follows oral surgery. Patients who take a corticosteroid often need fewer painkillers afterward because there’s simply less inflammation driving the pain.
Dexamethasone is often given before the procedure starts. The logic is straightforward: blocking inflammation before the surgical trauma triggers it is more effective than trying to rein it in afterward. Combining a corticosteroid with NSAIDs has been shown to reduce post-surgical complications without added safety concerns, making it a common approach for extractions that involve cutting into bone or tissue.
Antibiotics for Pain Caused by Infection
If your dental pain stems from an infection, like a tooth abscess, your dentist will likely prescribe an antibiotic alongside pain medication. Antibiotics don’t relieve pain directly, but they address the bacterial infection that’s causing it. Once the infection starts clearing, the pressure and throbbing typically ease significantly.
The most commonly prescribed antibiotic in dentistry is amoxicillin, a type of penicillin. If the infection is stubborn or you’re allergic to penicillin, your dentist has several alternatives:
- Amoxicillin with clavulanate, which adds a compound that helps the antibiotic work against resistant bacteria
- Cephalexin, a related antibiotic that works similarly to penicillin
- Metronidazole, often used for specific types of bacteria common in dental infections
- Azithromycin or erythromycin, broader alternatives for patients with penicillin allergies
- Clindamycin, typically reserved for infections that haven’t responded to other options
Local Anesthetics During Your Visit
The numbing injection you receive before a procedure is itself a prescribed medication. Most dental offices use amide-type local anesthetics, which last considerably longer than older formulations. Lidocaine is the most widely used, providing three to five hours of soft tissue numbness. Articaine is another common choice with a faster onset. For longer procedures or when extended post-operative numbness is helpful, bupivacaine can keep the area numb for four to nine hours.
Your dentist chooses among these based on how long the procedure will take and how much recovery pain they anticipate. A longer-acting anesthetic means you won’t feel anything for several hours after you leave, giving your prescribed pain medications time to kick in before the numbness wears off.
Pain Medication for Children
For children, the same non-opioid-first principle applies, but dosing is based on weight rather than age. Ibuprofen is dosed at 4 to 10 mg per kilogram of body weight every six to eight hours, with a ceiling of 400 mg per single dose. Acetaminophen follows a similar weight-based approach at 10 to 15 mg per kilogram every four to six hours.
The safety stakes are higher with children. When acetaminophen or ibuprofen are given as directed, the risk of harm is low. Opioids are a different story. Children can experience serious adverse effects from opioids, including hospitalization and death, even at doses considered therapeutic. Two specific opioids, codeine and tramadol, are outright contraindicated in children under 12 by the FDA. Topical benzocaine, the numbing gel sometimes used for teething or mouth sores, also carries a serious risk for infants and young children due to a condition called methemoglobinemia, which interferes with how blood carries oxygen.
What Most People Can Expect
For the vast majority of dental procedures, you’ll go home with instructions to take ibuprofen and acetaminophen on a schedule for a day or two, then as needed. This combination handles routine extraction pain, root canal soreness, and general post-procedure discomfort effectively. If your procedure was more involved, you might also get a short course of a corticosteroid or a few days of opioid medication to get through the first 48 hours. And if there’s any sign of infection, an antibiotic will be part of the plan.
The shift away from opioids as a default dental prescription has been significant. Non-opioid options aren’t just safer; they provide equal or better pain relief for most dental situations. If your dentist prescribes only ibuprofen and acetaminophen after a procedure, that’s not them being stingy with pain relief. It’s the current standard of care, backed by strong evidence that this combination outperforms opioids for typical dental pain.
