The home remedies that actually ease a toothache are a warm saltwater rinse, a cold compress on the outside of the cheek, and a small amount of diluted clove oil. Those three have a real mechanism behind them. Most of the other remedies circulating online do nothing, and a few of them measurably damage your teeth. Every remedy on this page buys you comfort while you wait, and none of them repairs the decay, crack, or infection producing the pain. Below we grade each popular remedy honestly, name the ones to skip and why, and explain what we recommend instead.
What Can You Put on a Tooth to Make It Stop Hurting?
You can put a cold compress against your cheek and a small amount of diluted clove oil on the tooth itself to make it stop hurting temporarily. Cold is the most reliable of the two, because it reduces swelling and slows the nerve signals coming from the inflamed area. Wrap ice in a cloth and hold it against the outside of your cheek for 15 to 20 minutes at a time, which is the interval Oral-B recommends in content reviewed by Dr. Robert Lee.
Direct application to the tooth is where people go wrong most often. Whatever you place on the tooth has to be safe against soft tissue, since the gum around a sore tooth is usually inflamed and more vulnerable than normal. That rules out most of what sits in a kitchen cabinet.
Rinsing is the gentler starting point, and it is the remedy nearly every dental and health authority names first.
How Does Salt Water Help a Toothache?
Salt water helps a toothache by drawing fluid out of swollen gum tissue and flushing debris and bacteria away from the sore area. Salt water works through osmosis, pulling excess fluid from inflamed tissue and reducing the pressure that makes a tooth throb. It also lifts trapped food particles out of the space between teeth, which is by itself the entire cause of a surprising number of toothaches.
Concentration matters more than people assume. The NHS directs patients to dissolve half a teaspoon of salt in a glass of warm water, rinse, and spit it out without swallowing. Warm, not hot, since heat against an inflamed tooth tends to intensify the ache rather than settle it.
Children should skip this remedy entirely. The NHS advises against saltwater rinses for children because of the risk that they will swallow the solution rather than spit it out.
How Long Does It Take for Salt Water to Work on a Toothache?
Salt water takes a few minutes to work on a toothache, and the relief typically lasts somewhere between 30 minutes and a couple of hours. Rinse for about 30 seconds, spit, and expect the throbbing to ease shortly afterward if trapped debris or gum inflammation was driving it. Repeating the rinse every few hours is reasonable.
The response tells you something useful. Pain that settles noticeably after a rinse usually originates in the gum tissue or from something lodged between teeth. Pain that does not budge at all is coming from deeper inside the tooth, where no rinse reaches, and that distinction is worth reporting when you call for an appointment.
Does Clove Oil Work for a Toothache?
Yes, clove oil works for a toothache on a short-term basis, because it contains eugenol, a compound with genuine mild anesthetic and anti-inflammatory properties. Eugenol numbs the surface it touches, which is why clove has been used for tooth pain for centuries and why eugenol still appears in dental materials today.
Dilution is not optional. Undiluted clove oil irritates gum tissue and the tongue and can cause a chemical burn of its own, so mix a drop or two with a neutral carrier oil, apply it to a cotton ball, and hold it against the sore area briefly. Swallowing clove oil in quantity is harmful, which is another reason to keep the amount small.
Expect minutes of relief rather than hours. Clove oil belongs in the same bracket as a cold compress: it makes waiting bearable and changes nothing underneath. That bracket is where every home remedy lands, which is worth looking at directly.
Do Home Remedies Actually Work for a Toothache?
Some home remedies genuinely work for a toothache, several do nothing measurable, and a few damage your teeth. The dividing line is whether a remedy has a mechanism that survives scrutiny. The table below grades the remedies that circulate most widely, drawing on guidance from Mayo Clinic, the NHS, the U.S. Food and Drug Administration, and published research on dental erosion.
| Remedy | What It Actually Does | Evidence Behind It | Our Verdict |
|---|---|---|---|
| Warm saltwater rinse | Draws fluid from swollen tissue, flushes debris | Recommended by the NHS with a set ratio | Use it, adults only |
| Cold compress on the cheek | Reduces swelling, constricts blood vessels | Standard first-aid guidance across sources | Use it, the most reliable option |
| Diluted clove oil | Eugenol numbs the surface briefly | Eugenol is an established dental material | Use sparingly, always diluted |
| Over-the-counter pain reliever | Reduces the inflammation driving the pain | Backed by the strongest clinical evidence available | Most effective option, follow the label |
| Cooled tea bag | Acts as a mild compress | Effect comes from temperature, not the tea | Harmless, but stains enamel |
| Hydrogen peroxide rinse | Reduces surface bacteria on gum tissue | No effect on bacteria inside a tooth | Limited value, never swallow it |
| Over-the-counter numbing gel | Numbs gum tissue on contact | FDA has flagged a rare blood-disorder risk | Ask a dentist first, never for toddlers |
| Vinegar or apple cider vinegar | Nothing useful for pain | Measured to strip minerals from enamel | Avoid entirely |
| Lemon or lime juice | Nothing useful for pain | Highly acidic, well below enamel’s safe range | Avoid entirely |
| Alcohol held against the tooth | Very brief surface numbing | Irritates inflamed tissue, no deep effect | Avoid, and never give to a child |
| Aspirin placed on the gum | Burns the tissue it touches | Mayo Clinic warns against it explicitly | Never do this |
Everything in the top half of that table shares one limitation: the relief is temporary and superficial. The strongest option listed is the one people often try last. The American Dental Association’s evidence-based guideline, published in the February 2024 Journal of the American Dental Association, identifies non-steroidal anti-inflammatory drugs alone or combined with acetaminophen as first-line therapy for temporarily managing a toothache, based on high to moderate certainty evidence from 82 randomized controlled trials. Follow the directions on the package and ask a pharmacist before combining anything.
The bottom half of the table deserves a closer look, because those remedies appear on plenty of well-meaning websites.
What Home Remedies Should You Avoid for a Toothache?
You should avoid any acidic remedy, any alcohol-based remedy, and anything placed directly against gum tissue that was not designed for it. Tooth enamel begins dissolving below a critical pH of roughly 5.5, and vinegar and citrus juice sit far below that threshold. Research on dietary acids found that vinegar produced a marked erosive effect on enamel, stripping roughly 17% of its calcium and phosphate content.
Erosion of that kind does not grow back. Published prevalence data puts some degree of dental erosion in up to 29% of adults aged 18 to 35, with about 3% showing severe erosion, and applying acid directly to a tooth that already hurts accelerates exactly that process. The irony is sharp: the remedy leaves you with a weaker tooth and the original pain.
Keep these off your list entirely:
- Vinegar or apple cider vinegar held against the tooth on a cotton ball, which strips minerals from enamel
- Lemon or lime slices bitten into near the sore tooth, which delivers concentrated acid to a vulnerable surface
- Whiskey, vodka, or other spirits swished or applied, which irritate inflamed tissue and numb nothing that matters
- Aspirin or any tablet pressed against the gum, which Mayo Clinic warns burns the soft tissue
- Undiluted essential oils of any kind, which cause chemical burns on gum tissue
- Heat applied to the cheek, which increases blood flow and usually worsens throbbing
Numbing gels sit in their own category and need a specific caution. The Food and Drug Administration has linked benzocaine, the active ingredient in most over-the-counter oral numbing products, to methemoglobinemia, a rare condition that reduces the blood’s oxygen-carrying capacity, and advises against using benzocaine products in children younger than two. Mayo Clinic now recommends speaking with a dentist or doctor before using any of them.
With the harmful options set aside, the question most people ask next is what is left to swallow.
What Should You Drink to Stop Tooth Pain?
Cool water is the best thing to drink for tooth pain, and there is no drink that treats the cause. Room-temperature or cool water rinses pigment and sugar away from the sore tooth without triggering the temperature response that sharp cold or heat produces. Nothing you swallow reaches the inside of a tooth, so the goal is simply to avoid making the pain worse.
Several common drinks reliably do make it worse. Very hot coffee and tea provoke inflamed pulp tissue, ice-cold drinks trigger the same nerve response from the other direction, and sugary drinks feed the bacteria driving decay. Citrus juices and sodas carry the same acid problem as the remedies above.
The temperature response itself is diagnostic. Pain that spikes from cold and fades quickly behaves differently from pain that lingers for a minute afterward, and that pattern of tooth sensitivity tells a dentist a good deal about what is happening inside the tooth. No drink resolves any of it, and neither does anything else at home once bacteria get past the enamel.
What Kills Bacteria in a Tooth?
Nothing you can use at home kills bacteria inside a tooth. Rinses, gels, and oils only contact the outer surfaces of the tooth and the surrounding gum, while the bacteria causing a serious toothache live inside the tooth where nothing topical reaches them. This is the single most important limitation of home care, and it is the reason a remedy can feel like it is helping while the problem advances.
Enamel is the barrier that makes this true. Once tooth decay breaks through enamel into the softer dentin and then into the pulp chamber, the bacteria sit behind a wall no mouthwash penetrates. Reaching them requires physically opening the tooth, which is a clinical procedure rather than a home one.
Bacteria below the gum line present a parallel problem, which is why gum treatment exists as its own category of care. Neither situation improves on its own, and one of them escalates faster than most people expect.
What Are Home Remedies for a Tooth Infection?
There are no home remedies for a tooth infection. An infected tooth needs clinical treatment, and home measures only manage the pain while the infection continues spreading. The pulp at the center of a tooth cannot heal itself from an infection the way other tissues in your body can, which means waiting does not lead to recovery.
From an infected pulp, bacteria move past the root tip into the surrounding bone and can form an abscess, a pocket of pus that produces swelling, a foul taste, pain on biting, and sometimes fever. An abscess spreading into the tissues of the face or neck stops being a dental problem and becomes a medical emergency.
Clearing an infection means removing its source, usually through root canal therapy or, where a tooth cannot be saved, extraction. Antibiotics alone do not resolve it, and pain at that level is well past what any remedy should be asked to handle.
What Can You Do at Home for Unbearable Tooth Pain?
For unbearable tooth pain, the right thing to do at home is call for an emergency dental appointment rather than search for a stronger remedy. Pain at that intensity almost always means an inflamed or dying pulp or an abscess, and both need treatment to resolve. A cold compress and an over-the-counter pain reliever taken as directed will get you to the appointment, and that is the entire realistic goal.
Go to a hospital emergency department instead if the pain comes with swelling around your eye or neck, or with any difficulty breathing, swallowing, or speaking. The NHS gives that instruction explicitly and advises against driving yourself there.
Severe pain that suddenly vanishes on its own deserves the same urgency as pain that persists, because a nerve that stops signaling has usually died rather than healed.
Can a Home Remedy Kill Tooth Nerve Pain?
No home remedy kills tooth nerve pain at its source. Nerve pain originates in the pulp, the soft tissue at the center of the tooth, inside a rigid chamber that cannot expand when it swells. That trapped pressure produces the deep throbbing people describe, and no rinse, oil, or gel reaches it.
Anti-inflammatory medication is the only home option that touches the mechanism, and it does so indirectly by reducing the swelling that creates the pressure. Relief arrives and then fades in a cycle as each dose wears off, which is precisely the pattern that signals a pulp problem rather than a gum one. Ending it permanently is a different conversation.
What Do Dentists Recommend for a Toothache?
Dentists recommend using home remedies only as a bridge to an appointment, then treating the cause directly. The standard sequence moves from symptom control to diagnosis to definitive treatment, and skipping the middle step is what turns a small problem into a large one. Here is the order we advise.
- Control the symptom safely. Warm saltwater rinse, cold compress on the cheek, and an over-the-counter pain reliever taken according to the label. Nothing acidic, nothing alcoholic, nothing pressed against the gum.
- Note what the pain does. Whether it throbs or stabs, whether it worsens with cold or with biting, whether it wakes you at night, and how long it has lasted. These details narrow the diagnosis considerably.
- Call within 48 hours. The NHS sets two days as the threshold for pain that needs professional attention, and Mayo Clinic gives the same guidance.
- Have the tooth examined and imaged. An exam and an X-ray show what is happening below the surface, which no symptom description can fully reveal.
- Treat the cause. Decay is cleaned out and the tooth sealed with dental fillings, a crack is covered, an infected pulp is removed, or an abscess is drained.
- Protect the result. Follow-up care keeps the repaired tooth stable and catches the next problem earlier.
Fear of that sequence is a real reason people stretch home remedies past the point of usefulness. Patients who delay because of dental anxiety should mention it when booking, since sedation options exist for exactly this situation.
We keep room in the schedule at our Bethesda office for patients in active pain, because a tooth treated this week is almost always a simpler fix than the same tooth treated next month. What a remedy cannot do, no matter how long you persist with it, is reverse the damage already done.
Can a Home Remedy Cure a Cavity?
No, a home remedy cannot cure a cavity. A cavity is a hole in the tooth where acid has dissolved the mineral structure, and no rinse, oil, or supplement rebuilds tooth structure that is already gone. Very early demineralization, before a hole forms, can sometimes remineralize with fluoride and good hygiene, but once the surface breaks the damage is permanent.
Scale explains why this question comes up so often. The Centers for Disease Control and Prevention reports that roughly 91% of adults aged 20 to 64 have had cavities in their permanent teeth, and Mayo Clinic identifies decay as the most common cause of toothache in both children and adults. Nearly everyone encounters this at some point.
Treatment is straightforward when the cavity is caught early. We remove the decayed tissue and restore the tooth with a tooth-colored filling, which typically takes a single visit.
Catching it early is the whole game. Spotting early decay before it reaches the nerve is what keeps a simple restoration from becoming something larger. Not every aching tooth shows its cause so plainly, though.
How Do You Treat a Toothache Under a Crown at Home?
You treat a toothache under a crown at home the same way you treat any toothache, with a saltwater rinse, a cold compress, and an over-the-counter pain reliever, but the underlying cause needs prompt attention. A crown covers the tooth, so pain beneath it usually means decay has started at the margin where the crown meets the natural tooth, the cement seal has failed, or the pulp inside has become inflamed.
None of those is visible to you or fixable at home. The crown itself does not decay, but the natural tooth structure underneath and around its edge does, and bacteria that slip under a loosened margin sit in a space a toothbrush cannot clean.
Pain when biting down often points to a seal problem, while lingering sensitivity to temperature points toward the pulp. A dental crown that has started aching should be examined quickly, since a tooth caught at the margin-decay stage can often be re-restored, while one left to progress may need the pulp treated first. Some aching teeth, meanwhile, turn out not to be the problem at all.
Why Does a Cold Cause Tooth Pain?
A cold causes tooth pain because your upper back teeth sit directly beneath the maxillary sinuses, and sinus swelling presses on the nerves serving those teeth. Sinus pressure produces a dull ache across several upper teeth at once rather than sharp pain in one specific tooth, which is the clearest way to tell the two apart.
Other clues point the same direction. Sinus-related tooth pain often worsens when you bend forward or lie down, it tends to affect both sides, and it arrives alongside congestion or facial pressure. A genuine dental toothache concentrates in one tooth and responds to biting on that tooth specifically.
No dental remedy helps this version, because nothing is wrong with the teeth. The ache resolves as the cold or sinus infection clears. Pain that outlasts the cold, or that narrows down to a single tooth as the congestion fades, has a dental cause after all and should be checked. Either way, there is a point where waiting stops being reasonable.
How Long Can You Rely on a Home Remedy?
You can rely on a home remedy for about two days, and no longer. The NHS advises seeing a dentist for any toothache lasting more than two days, and Mayo Clinic advises calling right away for pain continuing more than a day or two or arriving with fever or signs of infection. Pain that survives that window has a cause that will not resolve on its own.
Certain signs shorten that window to immediately: swelling in the cheek, jaw, or gums, fever alongside the pain, a foul taste or discharge near the tooth, pain when biting down, or pain that no over-the-counter reliever touches.
Prevention is what keeps you out of this loop. Brushing twice daily with fluoride toothpaste, cleaning between teeth every day, and keeping regular cleanings on the calendar stops most toothaches before they start.
Timing decides the cost of everything that slips through. Catching decay while filling the cavity is still a single short visit is the whole advantage, and the economics never change: the same problem costs less at the stage where it does not yet hurt.
Frequently Asked Questions
Does a Tea Bag Help a Toothache?
A tea bag helps a toothache only as a mild compress, and the benefit comes from temperature rather than from the tea. A cooled, damp tea bag held against the area works similarly to a cold compress but less effectively. Tea also stains enamel over time, so a wrapped ice pack is the better choice for the same purpose.
Does Hydrogen Peroxide Help a Toothache?
Hydrogen peroxide helps a toothache only slightly, by reducing bacteria on the gum surface and loosening debris. It does not reach bacteria inside a tooth, so it does nothing for pain coming from decay or an infected pulp. Dilute it heavily if you use it, never swallow it, and do not treat it as a substitute for an appointment.
Is It Safe to Put Alcohol on a Toothache?
No, it is not safe or effective to put alcohol on a toothache. The numbing effect lasts seconds and is entirely superficial, while the alcohol irritates gum tissue that is already inflamed. It should never be given to a child for tooth pain under any circumstances.
What Is the Best Home Remedy for a Toothache?
The best home remedy for a toothache is a cold compress combined with a warm saltwater rinse, used together. Cold reduces swelling from the outside while the rinse clears debris and eases gum inflammation from the inside. Adding an over-the-counter pain reliever taken according to its label gives the most complete temporary relief available at home.
Are Home Remedies Safe for Children?
Some home remedies are not safe for children. Children should not rinse with salt water because of the risk of swallowing it, children under 16 should not be given aspirin, and benzocaine numbing products should not be used in children under two. A cold compress on the outside of the cheek is the safest option, and a child in dental pain should be seen promptly through children’s dentistry care.
Can a Toothache Come Back After a Remedy Stops Working?
Yes, a toothache reliably comes back after a remedy stops working, because the remedy never addressed the cause. Relief that fades and returns in a cycle is the signature pattern of an inflamed pulp. Each cycle typically arrives sooner and lasts longer than the one before, which is a clear signal to stop managing and start treating.
The Takeaway
Three home remedies are worth your time: a warm saltwater rinse made with half a teaspoon of salt, a cold compress on the outside of the cheek for 15 to 20 minutes, and a small amount of diluted clove oil. An over-the-counter pain reliever used according to its label does more than any of them. Vinegar, citrus, alcohol, and aspirin pressed against the gum belong nowhere near a sore tooth, because acid strips minerals from enamel that never grow back.
Every one of those measures buys time and nothing more. Two days is the limit, and swelling, fever, or pain that will not respond means calling sooner. Reach us at (301) 530-2700 and tell us what the pain is doing, and we will find you a time.
