The most effective over-the-counter option for tooth pain is ibuprofen and acetaminophen taken together. Research from Case Western Reserve University found that 400 milligrams of ibuprofen combined with 1,000 milligrams of acetaminophen was superior to any opioid-containing medication studied for dental pain relief. The American Dental Association’s 2024 clinical practice guidelines confirm this combination as the first-line treatment for moderate to severe dental pain.
Why This Combination Works Better Than Either Drug Alone
Ibuprofen and acetaminophen relieve pain through different pathways, which is why taking them together outperforms either one on its own. Ibuprofen is an anti-inflammatory that blocks the production of chemicals your body releases at the site of inflammation. Since most tooth pain is driven by inflammation inside or around the tooth, ibuprofen targets the actual source of the problem. Acetaminophen works primarily in the brain to dampen pain signals. Together, they attack tooth pain from two directions at once.
This pairing also has a more favorable safety profile than opioids, which is why the ADA guidelines now explicitly state that opioids should not be the first choice for dental pain. Opioids don’t address the inflammation causing the pain, and they carry well-known risks of dependence.
Dosing by Pain Level
For mild tooth pain, either ibuprofen (200 to 400 mg every six hours) or acetaminophen (500 to 650 mg every six hours) alone is typically enough. For moderate to severe pain, take both: 400 mg of ibuprofen plus 500 to 650 mg of acetaminophen every six hours.
You can take both at the same time or stagger them every three hours so pain relief overlaps, though both approaches are safe. The key limits to stay within: no more than 1,200 mg of ibuprofen and 4,000 mg of acetaminophen in a 24-hour period when using over-the-counter doses. Exceeding the acetaminophen limit risks liver damage, especially with prolonged use. Ibuprofen taken on an empty stomach can irritate the stomach lining, so take it with food or a glass of milk when possible.
Topical Numbing Gels
Over-the-counter gels and liquids containing benzocaine can temporarily numb the area around a painful tooth. You apply a small amount directly to the gum tissue near the source of pain. Relief is fast but short-lived, usually lasting 15 to 30 minutes.
The FDA has issued safety warnings about benzocaine products. In rare cases, benzocaine can cause a condition called methemoglobinemia, where the blood’s ability to carry oxygen drops dangerously low. This risk is highest in young children, and benzocaine oral products should never be used on children under two. For adults, these products are generally safe for occasional, short-term use when label directions are followed. Don’t apply more than directed, and don’t use them as a long-term substitute for dental treatment.
Home Remedies Worth Trying
A warm saltwater rinse is the simplest home remedy that actually has a biological basis. Mix one teaspoon of salt into eight ounces of warm water and swish it gently around the painful area for 30 seconds. The salt draws fluid out of swollen gum tissue through osmosis and kills some bacteria by dehydrating them. This won’t fix the underlying problem, but it can reduce swelling and provide modest relief, especially if the pain involves infected or irritated gums. You can repeat the rinse several times a day.
Applying a cold pack to your cheek (20 minutes on, 20 minutes off) helps with pain that involves swelling. Cold constricts blood vessels and slows the inflammatory response. Avoid placing ice directly on the skin or on the tooth itself.
Signs Your Pain Needs More Than Painkillers
Over-the-counter pain relief is a bridge to dental treatment, not a replacement for it. Certain signs suggest the problem has progressed beyond what painkillers can manage. Fever, a general feeling of being unwell, swollen lymph nodes under your jaw, or visible swelling in your face or gums all point toward a possible dental abscess with systemic infection. The American Dental Association notes that when a dental condition progresses to systemic involvement with fever or malaise, antibiotics become necessary. These require a prescription and a dental or medical visit.
Other red flags include pain that wakes you from sleep, pain that doesn’t respond at all to the ibuprofen-acetaminophen combination, a foul taste in your mouth (which can indicate a draining abscess), or difficulty swallowing or opening your mouth. Dental infections can spread to surrounding tissue quickly, so these symptoms warrant same-day or next-day care rather than a wait-and-see approach.
Pain Relief During Pregnancy
If you’re pregnant, the decision about which painkiller to use is less straightforward. The FDA has stated that published research on pain relievers during pregnancy is “too limited to make any recommendations.” The ADA advises that pain relief decisions during pregnancy should be made in consultation with your obstetrician, who can weigh the specific risks and benefits for your trimester and medical history. Don’t assume that any over-the-counter painkiller is automatically safe during pregnancy, and don’t avoid treating significant dental pain either, since untreated infection carries its own risks.
What to Avoid
Placing aspirin directly on your gum tissue is a persistent folk remedy that actually burns the soft tissue and can cause a chemical ulcer. Swallow aspirin normally if you’re going to take it, though ibuprofen is generally more effective for dental pain.
Alcohol, whether swished in the mouth or consumed as a drink, doesn’t meaningfully reduce tooth pain and can irritate exposed tissue. Extremely hot or cold foods and drinks will often intensify the pain if the tooth’s nerve is exposed or inflamed. Stick to lukewarm foods and chew on the opposite side until you can get to a dentist.
