The single most effective thing you can do at home for a toothache is take ibuprofen and acetaminophen together, a combination that outperforms either drug on its own for dental pain. Beyond medication, a handful of other strategies, from salt water rinses to cold packs, can bring meaningful relief while you wait to see a dentist. But some widely shared home remedies are useless or actively harmful, and knowing the difference matters when you are in pain at midnight with no dental office open.
Why Ibuprofen and Acetaminophen Together Work Best
If you only do one thing, take both ibuprofen and acetaminophen at the same time. These two drugs attack pain through different pathways, and the combination delivers more relief than doubling down on either one alone. In a randomized trial after oral surgery, patients using both drugs together experienced significantly less pain over 48 hours than patients using the same daily dose of either drug by itself, and the researchers considered the difference clinically meaningful, not just a statistical blip.1British Journal of Anaesthesia. Combined acetaminophen and ibuprofen for pain relief after oral surgery in adults: a randomized controlled trial A second trial confirmed this, finding that a fixed-dose combination provided faster and greater pain relief than comparable doses of either agent alone or placebo across nearly every measure tested.2PubMed. Analgesic Efficacy of an Acetaminophen/Ibuprofen Fixed-dose Combination in Moderate to Severe Postoperative Dental Pain
A standard adult approach is 400 mg of ibuprofen alongside 500–1000 mg of acetaminophen, repeated every six to eight hours as needed. Because the two drugs are processed differently by your body, they do not compete with each other or increase each other’s side effects. Ibuprofen reduces inflammation at the source, while acetaminophen works primarily in the central nervous system to dampen pain signals. Stay within the labeled daily maximums for each drug: typically no more than 1200 mg of ibuprofen and 3000–4000 mg of acetaminophen in 24 hours for most adults, though you should check the packaging for your specific product.
One common mistake is reaching for opioid-containing painkillers left over from a previous prescription. For most dental pain, the ibuprofen-acetaminophen combination actually matches or outperforms many opioid combinations, with far fewer side effects. Save the leftover Vicodin for the recycling bin at your pharmacy, not for self-medicating a toothache.
Numbing Gels and Their Limits
Over-the-counter benzocaine gels, the kind sold as oral pain relievers in most pharmacies, can numb the tissue around a sore tooth and offer temporary relief. You apply a small amount directly to the gum near the painful area, and the numbing effect usually kicks in within a minute or two. Products range from 10% to 20% benzocaine concentrations.
The relief is real but short-lived, typically fading within 20 to 30 minutes. That makes benzocaine gels a useful bridge, something to get you through the worst spikes while waiting for oral pain medication to take effect, rather than a standalone solution.
There is one safety issue worth knowing about. Benzocaine has been linked in rare cases to a condition called methemoglobinemia, where the blood’s ability to carry oxygen drops. Most documented cases have involved spray formulations used during hospital procedures, but cases from over-the-counter gel use have also been reported, particularly involving overdose or use in young children.3PubMed Central. An evaluation of 10 percent and 20 percent benzocaine gels in patients with acute toothaches Pediatric exposures are especially concerning: in one review of children’s cases, measured methemoglobin levels in the most seriously affected patients ranged up to 55%, all requiring emergency treatment with intravenous methylene blue.4PubMed Central. Pediatric Exposures to Topical Benzocaine Preparations Reported to a Statewide Poison Control System For adults following the label directions, the risk is very small. For children under 12, the FDA recommends avoiding benzocaine products entirely for teething or mouth pain. If you use it, apply the smallest amount that does the job and do not reapply more often than the label allows.
Salt Water Rinses
Swishing warm salt water is one of the oldest dental home remedies, and it holds up reasonably well. Dissolve about half a teaspoon of table salt in a cup of warm water, swish for 30 seconds, and spit. The solution draws fluid out of inflamed gum tissue through osmosis, which can reduce swelling and ease discomfort. It also creates a mildly hostile environment for bacteria.
Research on saline rinses suggests they are more effective than they might seem for a kitchen-counter remedy. A scoping review found that simple saline solutions performed comparably to chlorhexidine, a prescription-strength antiseptic mouthwash, for certain oral health outcomes. At higher concentrations, saline’s antibacterial effect lasted several hours.5PubMed Central. From Thermal Springs to Saline Solutions: A Scoping Review of Salt-Based Oral Healthcare Interventions That does not mean a salt water rinse will cure an infection, but it may help keep things cleaner around the painful area while you wait for professional care. You can repeat the rinse several times a day without any real downside.
Cold Therapy
Applying something cold to the outside of your cheek, near the sore tooth, is another strategy backed by solid evidence. A literature review on cold therapy after intraoral surgery found that it reliably causes blood vessels to constrict, reduces swelling, and lowers pain perception in the treated area.6PubMed. Therapeutic efficacy of cold therapy after intraoral surgical procedures: a literature review While those studies focused on post-surgical pain, the mechanism applies to any situation where inflammation is part of the problem, which covers most toothaches.
Wrap ice or a cold pack in a thin cloth and hold it against the affected cheek for 15 to 20 minutes at a time, then take a break for at least 10 minutes before reapplying. Do not put ice directly against your skin, and avoid keeping it on continuously, as prolonged cold can damage tissue. The effect is temporary, but it stacks well with oral pain medication: take your ibuprofen-acetaminophen combination, then use the cold pack while waiting the 20 to 40 minutes it takes for the pills to kick in.
Clove Oil
Clove oil, or its active compound eugenol, has been used for dental pain for centuries, and dentists themselves still use eugenol-based preparations in clinical settings. The oil works as a mild local anesthetic and has some anti-inflammatory properties. Animal studies have demonstrated that clove extract produces a genuine analgesic effect, and that part of this effect appears to operate through the body’s opioid pain pathways, since blocking those pathways with naloxone reduced the pain relief.7PubMed Central. Analgesic effect of the aqueous and ethanolic extracts of clove
To use it, soak a small cotton ball or cotton swab in clove oil and apply it directly to the painful tooth and surrounding gum. You will feel a warming, numbing sensation almost immediately. Use it sparingly: clove oil is quite strong and can irritate soft tissue if you overdo it. A couple of drops on a cotton ball is enough. The effect is comparable in duration to benzocaine gels, lasting roughly 20 to 30 minutes, and you can reapply as needed. Many people find the taste intense and a bit unpleasant, but if your toothache is bad enough, you will not care.
Brushing and Flossing the Painful Area
It sounds counterintuitive when your mouth is throbbing, but gently cleaning the area around a toothache can actually reduce pain. Sometimes what feels like a deep toothache is partly caused or worsened by food debris packed between teeth or lodged under the gumline, pressing against inflamed tissue. Carefully brushing and flossing the area, even if it is tender, may dislodge that debris and provide immediate partial relief.
A review of home remedies for orofacial pain found that tooth brushing, flossing, and mouth rinsing had extensive and high-level scientific evidence supporting their use as emergency measures, alongside over-the-counter medication and cold therapy.8PubMed Central. Supportive Home Remedies for Orofacial Pain during the Coronavirus Disease 2019 Pandemic: Their Value and Limitations If a piece of trapped food is the main irritant, removing it may resolve the problem entirely. Even if the underlying cause is a cavity or infection, keeping the area clean limits the bacterial load and reduces the chance of the situation worsening before you reach a dentist.
The Hand Ice Massage Trick
This one sounds strange, but it has actual data behind it. Massaging the fleshy web of skin between your thumb and index finger with a piece of ice, on the same side as the toothache, can reduce dental pain intensity by half or more in a majority of people. A study testing this technique on patients with acute dental pain found that ice massage to this area produced reductions in pain comparable to those seen with acupuncture and electrical nerve stimulation. The effect was significantly greater than what could be explained by placebo or the sensation of touch alone.9PubMed Central. Relief of dental pain by ice massage of the hand
The area being stimulated corresponds to a well-known acupressure point. Rub a piece of ice in a circular motion on that spot for five to seven minutes. It is free, risk-free, and worth trying when you are waiting for medication to kick in or do not have painkillers available. The effect fades once you stop, so think of it as another bridge strategy rather than a cure.
What Not to Do
Some popular toothache remedies are not just ineffective; they can cause real harm. Two of the worst offenders deserve specific warnings.
Placing an aspirin tablet directly against the gum near a painful tooth is a folk remedy that persists despite being genuinely dangerous. Aspirin is acidic and, when held against soft tissue, acts as a chemical irritant. It causes protein coagulation in the tissue, leading to epithelial necrosis, erosion, and chemical burns on the gum and inner cheek.10Saudi Endodontic Journal. Chemical burn from direct application of aspirin onto a painful tooth The result is a painful white or raw-looking lesion on top of whatever dental pain you already had. Aspirin works by being absorbed through your stomach and entering your bloodstream. It does not numb tissue on contact. If you want to take aspirin for pain, swallow it.
Applying raw garlic to a toothache is another common suggestion, often framed around garlic’s antibacterial properties. While garlic does contain compounds with antimicrobial activity, placing it directly on your gums or inside your cheek can cause contact dermatitis, blistering, and chemical burns to the mucous membranes.11PubMed Central. Unforeseen sequela of a traditional remedy: A garlic burn case report Case reports describe ulcerative lesions from garlic application that required treatment in their own right. Eating garlic is fine, but do not wedge a raw clove against your gum.
Over-the-Counter Mouth Guards
If your toothache is worse in the morning or after periods of stress, clenching or grinding your teeth at night may be contributing. You might be tempted to pick up a cheap boil-and-bite mouth guard from a drugstore or order one online. These products do exist and are heavily marketed, but they come with caveats that matter.
A study examining over-the-counter bruxism splints available on the internet found that none of the designs provided full coverage of the biting surfaces, and a search of adverse event databases turned up potentially serious problems including choking hazards, tissue damage, and unwanted changes to how the teeth fit together. Because these are partial-coverage appliances, wearing them for extended periods may actually cause teeth to shift.12British Dental Journal. Over-the-counter (OTC) bruxism splints available on the Internet A professionally fitted night guard from a dentist is a different story, but grabbing a generic one from a pharmacy shelf to deal with a toothache is a gamble that can create new problems.
Hydrogen Peroxide Rinses
You may see recommendations for rinsing with diluted hydrogen peroxide as a toothache remedy. The idea is that hydrogen peroxide kills bacteria and reduces inflammation, and there is some truth to this. A clinical trial on a mouthwash containing hydrogen peroxide and hyaluronic acid found that it reduced inflammatory markers in saliva and decreased gum bleeding, performing comparably to chlorhexidine on several measures.13Dentistry 3000. A Randomized Clinical Trial on the Clinical and Immunological Efficacy of a Mouth Rinse Containing Hydrogen Peroxide and Hyaluronic Acid in Patients with Gingivitis
If you want to try it, use a 1% to 3% hydrogen peroxide solution (the standard brown bottle from the pharmacy is 3%), diluted with an equal part of water. Swish for 30 seconds and spit. Do not swallow it. Hydrogen peroxide rinses are not a substitute for salt water rinses or medication; think of them as an additional option if you happen to have a bottle under the sink. Undiluted or overly concentrated peroxide can irritate your gums, so more is not better here.
Timing and Stacking Strategies
When you are dealing with a bad toothache at home, the order in which you do things matters. Here is a practical sequence that makes the most of the strategies above:
- First: Take ibuprofen and acetaminophen together. These take 20 to 40 minutes to reach full effect.
- While waiting: Gently brush and floss the area to remove any trapped debris. Follow with a warm salt water rinse.
- For immediate relief: Apply a cold pack to the outside of your cheek, or try the hand ice massage technique, or dab clove oil or benzocaine gel on the gum near the tooth.
- Ongoing: Repeat the salt water rinse every few hours. Take your next dose of pain medication on schedule rather than waiting for the pain to return.
Staying ahead of the pain is easier than chasing it. If you wait until the pain is at its worst before taking more medication, you will spend an uncomfortable gap waiting for the next dose to work. Set a timer for your next dose and take it before the current one fully wears off.
When Home Remedies Are Not Enough
Everything described here is a holding action, not a treatment for whatever is actually wrong with the tooth. Certain signs mean you should seek care urgently rather than managing things at home for another day or two:
- Fever: A toothache accompanied by fever suggests the infection may be spreading beyond the tooth.
- Swelling in your face or neck: Visible swelling, especially if it is warm to the touch or growing, can indicate an abscess that needs drainage.
- Difficulty breathing or swallowing: Severe swelling from a dental infection can compromise your airway. This is a medical emergency.
- Pain that does not respond to medication: If a full dose of ibuprofen and acetaminophen together barely takes the edge off, the underlying problem likely needs professional intervention.
- Broken or knocked-out tooth: Structural damage to a tooth will not improve on its own and may worsen without timely treatment.
Dental infections can become dangerous. An untreated abscess can spread to the jaw, neck, or even the brain. The home strategies in this article can buy you time and comfort, but they cannot replace a dentist identifying the cause and fixing it. If your area has an emergency dental clinic or a hospital emergency department with oral surgery coverage, those are your options when the pain is severe and your regular dentist is unavailable.
Why the Pain Sometimes Goes Away on Its Own
Occasionally a toothache that had you doubled over will seem to vanish after a day or two, and it is tempting to cancel that dental appointment. This is rarely a good sign. When a tooth with an infected or dying nerve suddenly stops hurting, it often means the nerve has finished dying and is no longer sending pain signals. The infection is still there, quietly progressing. It may form an abscess at the root tip, damage the surrounding bone, or flare back up weeks later with even more intensity. A toothache that disappears without treatment deserves the same dental visit as one that persists. The absence of pain is not the same thing as the absence of a problem.
