The most effective option you can buy without a prescription is ibuprofen and acetaminophen taken together. This combination outperforms either drug alone and, according to American Dental Association guidelines, provides better pain relief with fewer side effects than opioids. Below is everything that can help while you wait to get the tooth treated.
Why Anti-Inflammatory Drugs Work Best
Severe tooth pain usually comes from inflammation inside the tooth’s nerve chamber, a condition called pulpitis. When that tissue becomes inflamed or infected, your body floods the area with chemicals like prostaglandins and bradykinin that sensitize nerve endings, lower their firing threshold, and eventually cause them to fire on their own. That’s why the pain can throb without anything touching the tooth.
Because the root cause is inflammation, drugs that block it at the source (like ibuprofen and naproxen) tend to work far better than pure pain-blockers like acetaminophen alone. Acetaminophen still helps through a different pathway, which is why combining the two gives you the strongest relief available over the counter.
The Best OTC Combination and How to Take It
Take 400 mg of ibuprofen alongside 500 mg of acetaminophen. You can repeat this every six to eight hours. This staggered, dual approach attacks pain through two separate mechanisms and is now the first-line recommendation from the ADA for both toothaches and post-extraction pain.
Stay within these daily ceilings to avoid organ damage:
- Acetaminophen: no more than 4,000 mg in 24 hours. If you drink alcohol regularly, the safe limit is lower.
- Ibuprofen: no more than 1,200 mg in 24 hours when self-dosing over the counter.
A combined tablet (250 mg acetaminophen plus 125 mg ibuprofen) is also available. The standard dose is two tablets every eight hours, with a maximum of six tablets per day. Either approach, separate pills or the combination tablet, works. Just don’t double up on acetaminophen by accidentally taking it in multiple products like cold medicines or sleep aids.
If ibuprofen bothers your stomach or you can’t take it, naproxen is another anti-inflammatory option. It lasts longer per dose, so you take it less often, but it serves the same purpose.
Topical Relief With Clove Oil
Clove oil contains eugenol, a compound dentists have used for decades. It temporarily numbs nerve endings and reduces local inflammation. You can use it alongside oral painkillers for an extra layer of relief.
To apply it safely, dilute 3 to 5 drops of clove oil in one teaspoon of a carrier oil like olive or coconut oil. Dip a cotton ball or swab into the mixture and press it gently against the gum around the painful tooth, not directly on the tooth itself. Hold it in place for a few minutes, then remove. You can reapply every two to three hours. For more widespread mouth pain, swish the diluted mixture gently and spit it out.
Undiluted clove oil can irritate or burn soft tissue, so always dilute it first.
Saltwater Rinses
A warm saltwater rinse won’t stop severe pain on its own, but it reduces bacteria and draws fluid out of swollen tissue, which can take the edge off. Dissolve one and a half teaspoons of table salt in eight ounces of warm water. Swish gently for 30 seconds and spit. You can repeat this one to three times a day.
What a Dentist Can Prescribe
If over-the-counter options aren’t enough, a dentist or emergency provider has stronger tools. Ketorolac is a prescription-strength anti-inflammatory with pain relief comparable to morphine in clinical studies, without the addiction risk of opioids. It’s available as a pill, injection, or nasal spray, and a single 30 mg dose has been shown to significantly reduce pain after extractions and during acute flare-ups.
For pain driven by deep infection or inflammation inside the tooth, a short course of a corticosteroid like dexamethasone or prednisolone can provide relief lasting up to 24 hours. These are typically used as a bridge to get you comfortable before a root canal or extraction. Antibiotics may also be necessary if the infection has spread beyond the tooth.
The key point: definitive treatment (a root canal, extraction, or drainage of an abscess) is the only thing that resolves severe tooth pain permanently. Medications buy you time, but the underlying problem needs to be addressed.
What Not to Do
Don’t place aspirin directly on your gum. This is a persistent home remedy that causes chemical burns to soft tissue and doesn’t improve absorption. Don’t apply heat to the outside of your face if you suspect an infection, as warmth can accelerate bacterial spread. Ice packs on the cheek (20 minutes on, 20 minutes off) are a safer choice for temporary relief.
Avoid very hot, very cold, or sugary foods and drinks, all of which can trigger sharper pain in an exposed or inflamed nerve.
Signs That Require Emergency Care
Most toothaches are urgent but not emergencies. A few situations, however, need immediate attention. Facial swelling that spreads toward your eye or down your neck is a sign of a serious infection that can compromise your airway. Difficulty swallowing or breathing, fever combined with swelling, uncontrolled bleeding that makes you feel faint, or a jaw injury from trauma all warrant an emergency room visit rather than waiting for a dental appointment.
