Taking ibuprofen and acetaminophen together is the single most effective thing you can do for a toothache before you can get to a dentist. That combination outperforms many prescription opioid formulations for dental pain, according to systematic reviews of clinical trials. But pain relief is only half the story: a toothache is almost always a symptom of something that will not resolve on its own, and what you do in the hours and days around that pain matters for both your comfort and the outcome of whatever treatment comes next.
Why Ibuprofen Plus Acetaminophen Works Better Than Either Alone
These two drugs attack pain through different pathways. Ibuprofen is an anti-inflammatory that reduces the swelling driving most tooth pain, while acetaminophen works centrally in the brain to dampen pain signaling. Used together, they complement each other without compounding side effects the way adding an opioid would. A systematic review published in the Journal of the American Dental Association found that the ibuprofen-acetaminophen combination may be a more effective analgesic, with fewer adverse effects, than many opioid-containing formulations currently available.1Journal of the American Dental Association. Combining ibuprofen and acetaminophen for acute pain management after third-molar extractions: Translating clinical research to dental practice
For adults, a common approach is 400 to 600 mg of ibuprofen alongside 500 to 1,000 mg of acetaminophen, taken every six to eight hours. You can stagger them so that you take one, then the other three hours later, keeping a steady level of relief. Stay within each drug’s daily maximum (usually printed on the bottle), and avoid this combination if you have kidney disease, liver problems, or stomach ulcers without talking to your doctor first.
Topical Treatments That Offer Fast but Temporary Relief
When you need something to bridge the gap before oral painkillers kick in, or when swallowing a pill is not practical, topical agents applied directly to the sore area can help within minutes.
Benzocaine Gels
Over-the-counter benzocaine gels (sold under brand names like Orajel and Anbesol) numb the tissue around the tooth. In an early controlled trial, about 83% of patients who applied benzocaine to an aching tooth got relief, compared with 16% using a placebo, with the average onset time at roughly four minutes.2Oral Surgery, Oral Medicine, Oral Pathology. Efficacy of using benzocaine for temporary relief of toothache A larger trial comparing concentrations found that 20% benzocaine gel produced faster, more consistent relief than 10%, and both significantly outperformed a vehicle gel with very few side effects.3PubMed Central. An evaluation of 10 percent and 20 percent benzocaine gels in patients with acute toothaches Efficacy, tolerability and compliance with label dose administration directions The numbing is genuinely temporary, usually lasting under an hour, so benzocaine is a stopgap rather than a fix.
One important caution: benzocaine should not be used in children under two years old due to the rare but serious risk of methemoglobinemia, a condition where the blood’s ability to carry oxygen drops. The risk in adults is extremely low, and the larger trial noted zero cases among its several hundred participants, but it is worth knowing about.
Clove Oil and Eugenol
Clove oil has been used for toothaches for centuries, and the active ingredient, eugenol, has genuine analgesic and mild anti-inflammatory properties. Research suggests eugenol interacts with one of the same enzyme targets that ibuprofen does.4Indonesian Journal of Pharmaceutical Science and Technology. Antioxidant Activity of VCO-Clove Topical Oil and Predictive Interaction toward Prostaglandin-endoperoxide Synthase 2 In a clinical study comparing eugenol to a control group, the majority of patients who applied eugenol reported reduced toothache intensity within five minutes, and most experienced pain relief lasting around 72 hours.5Clinical Dentistry (Russia). Extraction and evaluation of eugenol from Syzgium aromaticum as topical anesthetic for toothaches That duration is longer than what you get from benzocaine, which makes clove oil a reasonable option if you are waiting days rather than hours for a dental appointment.
To use it, dab a small amount of clove oil onto a cotton ball and hold it against the sore tooth and surrounding gum. The taste is strong and can irritate soft tissue if overused, so a little goes a long way. Clove oil is widely available at pharmacies and health-food stores.
Simple Home Measures That Actually Help
Beyond pills and gels, a few low-tech approaches can take the edge off while you wait for professional care.
A warm saltwater rinse is one of the oldest and most reliable home remedies. Dissolving half a teaspoon of salt in a glass of warm water and swishing gently for 30 seconds can reduce bacterial load around an inflamed tooth and soothe irritated gum tissue. A randomized clinical trial found that saltwater rinses had anti-inflammatory properties comparable to chlorhexidine, the antiseptic mouthwash dentists commonly prescribe after surgery.6PubMed. Anti-inflammatory effect of salt water and chlorhexidine 0.12% mouthrinse after periodontal surgery: a randomized prospective clinical study You can repeat this several times a day without risk.
Cold compresses are another standby, though the evidence is mixed. One study on patients after wisdom tooth removal found that continuous cold application to the cheek significantly reduced both pain and swelling compared with a control group.7Chinese Journal of Practical Nursing. The effects of two different cold compress modes on swelling and pain among patients receiving extraction of impacted tooth of mandibular However, another randomized trial found cold therapy had no significant benefit after impacted third-molar surgery.8PubMed. Effectiveness of cold therapy in reducing pain, trismus, and oedema after impacted mandibular third molar surgery: a randomized, self-controlled, observer-blind, split-mouth clinical trial The discrepancy probably comes down to timing and technique: holding a cold pack against the outside of your cheek in 15-to-20-minute intervals during the first several hours is unlikely to hurt and may help, even if it is not a guaranteed fix.
Keeping your head slightly elevated when lying down can also reduce throbbing. Blood pools in the head when you lie flat, which increases pressure on inflamed dental tissue. An extra pillow at night is a simple adjustment that makes a real difference for some people.
What You Should Avoid Doing
Some common instincts make things worse. Placing aspirin directly on the gum next to an aching tooth is a persistent folk remedy that actually causes a chemical burn on the tissue, adding injury to an already painful situation. Very hot or very cold foods can trigger sharp spikes of pain in a tooth with exposed dentin or an inflamed nerve. Alcohol, whether swished in the mouth or consumed to “take the edge off,” can interact badly with ibuprofen and acetaminophen, and does not meaningfully numb dental pain anyway.
Perhaps the most important thing to avoid is assuming that if the pain fades, the problem is gone. Dental infections can go through cycles of intense pain followed by quiet periods when the nerve tissue dies or the pressure temporarily equalizes. The infection is still progressing during those quiet stretches.
When Antibiotics Are and Are Not the Answer
Many people visit an urgent care clinic or call their doctor hoping for antibiotics when a toothache strikes. The evidence is clear that antibiotics alone do not fix toothaches and are not even indicated unless the infection has started to spread. Without signs of spreading infection, antibiotics have not been shown to reduce pain or prevent further dental complications.9PubMed Central. Managing tooth pain in general practice
A systematic review of antibiotic use in dental infections reinforced this point: once drainage is performed or the source of the infection is removed, all tested antibiotics are equally effective, and no antibiotic is as successful as the local intervention (the dental procedure itself). When antibiotics are truly needed, they should be used for the shortest time possible.10PubMed. The Use of Antibiotics in Odontogenic Infections: What Is the Best Choice? A Systematic Review In other words, the drill or the extraction fixes the problem; the antibiotic just controls whatever has spread beyond the tooth. Taking antibiotics when you do not need them contributes to resistance and delays the real treatment.
Signs that an infection may be spreading, and antibiotics may be warranted alongside dental care, include fever, facial swelling that is getting larger rather than stable, difficulty swallowing or opening your mouth, and feeling generally unwell beyond just having a sore tooth.
Red Flags That Require Urgent Medical Attention
Most toothaches, while miserable, are not emergencies in the medical sense. A few situations cross that line. Ludwig’s angina is a severe, rapidly progressing infection of the floor of the mouth that can develop from a dental abscess, causing bilateral swelling under the chin, difficulty swallowing, limited mouth opening, and voice changes.11British Dental Journal. Ludwig’s angina Left untreated, it can compromise the airway. This is a hospital emergency, not a dental-office visit.
Other warning signs that warrant a trip to the emergency room rather than waiting for a dental appointment include:
- High fever: a temperature above 101°F (38.3°C) alongside dental pain suggests systemic infection
- Spreading swelling: redness and swelling extending toward the eye, down the neck, or across the midline of the face
- Breathing difficulty: any sense that the swelling is affecting your ability to breathe or swallow
- Uncontrolled bleeding: after a dental injury or extraction that will not stop with firm pressure
Professional Treatment Options
The definitive treatment for a toothache depends on its cause, but the two most common paths are root canal therapy and extraction. Both are effective at eliminating pain long-term. A prospective cohort study found that patients who received either treatment reported significant improvement in physical pain at one year compared with baseline, with no major differences in oral health-related quality of life between the two groups.12PubMed Central. A comparison of oral health-related quality of life and satisfaction among patients undergoing root canal treatment or tooth extraction – A prospective controlled cohort study Patients who started root canal treatment also reported significant improvement and generally high satisfaction.13PubMed. Comparing Quality of Life of Patients Undergoing Root Canal Treatment or Tooth Extraction
The choice between saving the tooth and removing it depends on factors like how much healthy tooth structure remains, whether the tooth is restorable with a crown, cost considerations, and the tooth’s location and function. A front tooth or a molar that anchors a bridge is worth more effort to save than a wisdom tooth. Your dentist will weigh these factors and discuss them with you, but the key reassurance is that both routes lead to real, lasting relief.
Managing Pain for Children
Children get toothaches too, and managing their pain requires some different considerations. An evidence-based guideline from the American Dental Association recommends non-opioid medications for acute dental pain in children under 12, specifically ibuprofen or naproxen alone or in combination with acetaminophen.14PubMed Central. Evidence-based clinical practice guideline for the pharmacologic management of acute dental pain in children A systematic review and meta-analysis confirmed that the combination of acetaminophen and ibuprofen appears to be the most effective option for dental pain after extractions in children 12 and younger.15PubMed Central. Analgesics for the management of acute dental pain in the pediatric population: A systematic review and meta-analysis
Weight-based dosing matters much more in children than in adults, so follow the dosing chart on the bottle or your pediatrician’s guidance rather than eyeballing it. Aspirin should never be given to children due to the risk of Reye’s syndrome. And as mentioned, benzocaine gels are not recommended for children under two.
Toothache During Pregnancy
Pregnant women face a frustrating bind: hormonal changes increase the risk of gum inflammation and tooth decay, yet many worry that dental treatment could harm the baby. The reality is that untreated dental infections pose a greater risk to pregnancy than the treatment itself. Endodontic care, including root canals, can be performed during pregnancy when needed to control pain from irreversible pulpitis or active infection. Important considerations include choice of local anesthetic, analgesics that are safe for the pregnancy, appropriate antibiotic selection when infection has spread, and minimizing X-ray exposure, though modern dental X-rays with proper shielding deliver very low radiation doses.
Acetaminophen is generally considered the safest pain reliever during pregnancy. Ibuprofen is typically avoided in the third trimester because of potential effects on fetal circulation. If you are pregnant and dealing with a toothache, do not delay seeking care out of fear that the dentist cannot help you. The second trimester is often considered the ideal time for elective procedures, but emergencies can and should be treated at any stage.
When the Problem Is Not Actually the Tooth
Not every pain that feels like a toothache originates from a tooth. Several conditions mimic dental pain well enough to send people to the dentist for a problem the dentist cannot find. Known examples include jaw muscle pain (myofascial pain), trigeminal neuralgia, post-traumatic nerve pain, neurovascular pain similar to migraines, cardiac pain, and sinus disease.16PubMed. Differential diagnosis of toothache to prevent erroneous and unnecessary dental treatment
Sinus infections deserve special mention because they are extremely common and frequently cause pain in the upper back teeth, right where the roots of those teeth sit close to the floor of the maxillary sinus. If your “toothache” involves multiple upper teeth on the same side, gets worse when you bend forward, and coincides with nasal congestion, you may be dealing with sinusitis rather than a dental problem. A course of decongestants and time may resolve it, though a dentist or doctor can help sort it out.
Cardiac pain referring to the lower jaw is rarer but more serious. It tends to come on with exertion, may involve the left side, and often accompanies chest pressure or shortness of breath. Anyone with jaw pain plus these accompanying symptoms should seek emergency medical care immediately rather than assuming it is dental.
Dental Trauma and Knocked-Out Teeth
A toothache caused by a blow to the face or a fall is a different situation from one caused by decay. Traumatic dental injuries, including fractures and displacement of teeth, are common and require prompt assessment.17PubMed. Emergency assessment and treatment planning for traumatic dental injuries If a permanent tooth gets completely knocked out, the single most important thing you can do is keep it moist. Pick it up by the crown (the white part, not the root), gently rinse off any visible dirt without scrubbing, and either place it back in the socket if you can or store it in milk or saliva. Time is critical: reimplantation within 30 minutes gives the best chance of saving the tooth. Get to a dentist or emergency room as quickly as possible.
For a cracked or broken tooth that has not been knocked out, rinsing with warm water and applying a cold compress to the outside of the cheek can manage things while you arrange an emergency dental visit. Over-the-counter pain relievers (the ibuprofen-acetaminophen approach) are appropriate here too. Avoid chewing on the affected side.
Dental Anxiety and Pain Perception
A significant number of people delay treatment for toothaches because they fear the dentist more than they fear the pain. This is not a character flaw; dental anxiety is well-studied and has real physiological effects, including heightened pain perception that makes procedures genuinely feel worse for anxious patients. A systematic review found that both psychological approaches like cognitive behavioral therapy and pharmacological options like nitrous oxide or mild sedatives significantly reduce anxiety and pain, and combining the two yields the best results.18PubMed Central. Anxiety and Pain Management in Dental Patients: A Systematic Review of Pharmacological and Non-Pharmacological Approaches
A randomized trial comparing two forms of therapy found that both produced lasting improvements in pain coping and reduced pain perception intensity in patients with dental anxiety, with the effects holding at follow-up.19Dental Research Journal. Comparison of the effect of acceptance and commitment therapy and cognitive behavioral therapy on pain tolerance and intensity perception in patients with dental anxiety: A randomized trial If fear is what stands between you and treatment, mention it to the dental office when you call. Many practices now offer sedation dentistry or have protocols specifically for anxious patients, ranging from simple distraction techniques to conscious sedation with medication.20PubMed Central.

Getting Care When Access Is Limited
Knowing the right treatment does not help much if you cannot get to a dentist. Dental pain is one of the most common reasons people show up at hospital emergency departments, where physicians can prescribe pain medication but generally cannot perform root canals or extractions. Teledentistry has emerged as a middle ground. During the COVID-19 pandemic, a teledentistry service in Qatar found that about 70% of dental calls could be managed remotely with advice and prescriptions, while roughly 30% needed in-person referral. Orofacial dental pain was the most common reason people called, accounting for about 42% of contacts.21PubMed Central. Role of Newly Introduced Teledentistry Service in the Management of Dental Emergencies During COVID-19 Pandemic in Qatar: A Cross-Sectional Analysis Higher pain scores were associated with a greater likelihood of needing a face-to-face visit, with each one-point increase in self-reported pain raising the odds of referral by about 40%.22PubMed Central. Patient-reported orofacial-dental pain severity and tele-triage decisions during COVID-19 pandemic: Does the severity of pain drive tele-triage decisions?
If you cannot see a dentist right away, a virtual or phone consultation can help you figure out whether your situation is manageable at home for a few days or needs urgent attention. Many dental offices and some telemedicine platforms now offer same-day or next-day virtual triage. In the meantime, the combination of ibuprofen, acetaminophen, saltwater rinses, and topical relief can keep you functional while you arrange definitive care. The one thing you should not do is simply ride it out indefinitely. A toothache that goes away on its own almost never means the underlying problem resolved; it usually means the nerve died, and the infection is quietly expanding.
