Ketorolac is one of the most effective over-the-counter-strength pain relievers available for tooth pain, and in clinical trials it outperformed ibuprofen for several types of dental pain. It’s a prescription-only anti-inflammatory drug (sold under the brand name Toradol) that works by blocking the enzymes responsible for producing prostaglandins, the chemicals your body releases at sites of inflammation that amplify pain signals. Because dental pain is heavily driven by inflammation, ketorolac hits the problem at its source.
How It Compares to Ibuprofen
In a randomized controlled trial of patients with irreversible pulpitis (the deep, throbbing pain from an inflamed tooth nerve), ketorolac consistently produced lower pain scores than ibuprofen across multiple stages of dental treatment. During initial drilling into the tooth, ketorolac patients reported a median pain score of 2 on a verbal rating scale compared to 3 for ibuprofen and 4 for placebo. During canal cleaning, ketorolac patients scored a median of 1 versus 2 for ibuprofen and 3 for placebo. The differences at the dentin and debridement stages were statistically significant.
For deeper pulp pain, ketorolac and ibuprofen performed about equally, both significantly better than placebo. A separate study comparing an intramuscular injection of ketorolac (50 mg) to a high dose of oral ibuprofen (800 mg) found them equivalent, with both providing effective relief in about 60% of cases. So ketorolac has a measurable edge for certain types of dental pain, though in some scenarios it performs similarly to high-dose ibuprofen.
How Quickly It Works
Oral ketorolac is taken as a tablet every 4 to 6 hours, either on a set schedule or as needed for pain. Most people begin to notice relief within 30 to 60 minutes of taking a dose. Some dentists administer ketorolac as an intramuscular or intravenous injection, which delivers faster relief because it bypasses the digestive system. An injection may be given before a procedure as a preemptive strike against pain or afterward in the office before you’re sent home with oral tablets.
The Five-Day Limit
Ketorolac is strictly a short-term medication. You cannot take it for more than five days total, including any time you received it by injection. This hard limit exists because ketorolac carries a higher risk of serious side effects than most other anti-inflammatory drugs, and those risks climb with extended use.
It’s designed for moderately severe pain, not mild discomfort or chronic conditions. If your tooth pain persists beyond five days, you’ll need a different pain management approach and likely a dental procedure to address the underlying problem.
Risks and Side Effects
Ketorolac’s main risks center on the stomach, kidneys, and bleeding. Among all anti-inflammatory drugs studied, ketorolac had the highest relative risk for peptic ulcers at 11.5 times the baseline risk. It can cause stomach ulcers, intestinal bleeding, or perforations that may occur without warning symptoms. It also carries the highest odds ratio for kidney damage among common anti-inflammatories, with a 2.58 odds ratio for chronic kidney disease even with short-term use of up to 90 days, compared to 1.08 for anti-inflammatories as a class.
Because ketorolac interferes with platelet function (the blood’s clotting mechanism), it can increase bleeding. One large study found patients receiving ketorolac had a 30% higher odds of gastrointestinal bleeding compared to those receiving opioid painkillers. However, a meta-analysis of 27 randomized trials found no significant increase in surgical site bleeding specifically. The bleeding risk is most pronounced in people over 75 and at daily doses exceeding 105 mg, where the odds of both gastrointestinal and surgical bleeding roughly tripled.
Who Should Not Take It
Ketorolac is not an option if you have:
- Active or recent stomach ulcers or GI bleeding, or a history of either
- Kidney disease or impaired kidney function, including dehydration that puts the kidneys at risk
- A bleeding disorder or current use of blood-thinning medications, since ketorolac amplifies bleeding risk
Elderly patients face greater risk across all three categories. If you take blood thinners, corticosteroids, or other anti-inflammatory drugs, combining them with ketorolac significantly raises the chance of dangerous bleeding or kidney problems.
Use in Children
Ketorolac is not approved for general pediatric use. The one exception is short-term postoperative pain, where it has been studied in children as young as 4. It offers an advantage over opioid painkillers in that it doesn’t cause respiratory depression, nausea, constipation, or any risk of dependence. Still, the same concerns about stomach irritation, bleeding, and kidney effects apply, and dosing decisions for children are made on a case-by-case basis by the prescribing provider.
What This Means for Your Toothache
If you’re dealing with severe dental pain and your dentist or doctor prescribes ketorolac, it’s one of the strongest non-opioid options available. It works especially well for the inflammatory component of tooth pain, which is the dominant driver in conditions like pulpitis, abscesses, and post-extraction soreness. For people who can safely take it, ketorolac provides relief that’s equal to or better than high-dose ibuprofen without the sedation, addiction risk, or mental fog that comes with opioid alternatives.
The tradeoff is a tighter safety window. Five days maximum, a longer list of contraindications than ibuprofen, and more serious potential side effects. It’s a powerful tool for bridging the gap between when tooth pain strikes and when definitive dental treatment can fix the underlying cause.
