You can relieve a toothache at home with a warm salt water rinse, a cold compress held against your cheek, over-the-counter pain relief taken as directed, gentle flossing to clear any trapped food, and sleeping with your head raised. Those steps control the pain. None of them fixes what is causing it, which is why pain lasting more than one to two days needs a dentist regardless of how well home care is working. Below we cover the order to do things in, why each step works, what to avoid, why pain that stops on its own is a warning rather than a relief, and the point at which waiting stops being safe.
How Do You Fix a Toothache?
You fix a toothache in two parts: home care that controls the pain now, and dental treatment that removes the cause. Both matter, and they are not interchangeable. A salt water rinse and an anti-inflammatory can make a terrible evening tolerable, and neither touches the cavity, crack or infection underneath.
Tooth pain works differently from most pain in the body. The nerve sits inside a sealed chamber of hard enamel and dentin, so when the tissue inside swells, it has nowhere to expand. That trapped pressure is what produces the deep throbbing people describe, and it is also why a toothache rarely eases the way a sore muscle does.
Because the pressure is structural, the pain tends to escalate rather than resolve. CDC figures show nearly 21% of adults aged 20 to 64 have at least one tooth with untreated decay, which is the most common starting point for this kind of pain. Home care buys you time to get an appointment. It is a bridge rather than a destination.
What Should You Do First When a Toothache Starts?
When a toothache starts, rinse with warm salt water, clear any trapped food, apply cold to the outside of your cheek, take over-the-counter pain relief as directed, and keep your head raised. Doing those in order works better than doing them at random, because each step sets up the next.
Run the first hour like this:
Rinse gently with warm salt water to clean the area and calm the surrounding gum tissue.
Floss carefully around the sore tooth to remove any trapped food, which is a surprisingly common cause of sudden pressure pain.
Hold a cold compress or a cloth-wrapped ice pack against the outside of your cheek in intervals of about 15 to 20 minutes.
Take an over-the-counter pain reliever following the directions on the package.
Sit upright or prop your head on extra pillows rather than lying flat.
Eat something soft and lukewarm, chewing on the opposite side.
Call a dental office as soon as one opens, even if the pain has settled by then.
Step two surprises people most often. Food wedged tightly between two teeth presses on the gum and the ligament around the root, and it can produce pain that feels identical to a cavity until the debris comes out. Flossing once, gently, is worth trying before you assume the worst. If you are a patient of ours, Dr. Cho would rather hear from you early in the day than find out on Monday that you spent the weekend in pain.
How Does a Salt Water Rinse Help a Toothache?
A salt water rinse helps a toothache by cleaning debris out of the area, reducing inflammation in the gum tissue, and making the environment less comfortable for bacteria. It is the most useful home step available, and it is useful for reasons that are mechanical rather than magical.
Salt water draws fluid out of swollen tissue by osmosis, which eases the pressure in an inflamed gum. The rinsing action itself flushes food particles and bacteria away from the sore spot. Warm water is specified because it dissolves the salt properly and because it is gentler on an already irritated tooth than cold water would be.
Technique is simple. Dissolve about half a teaspoon of salt in a glass of warm water, swish gently for roughly 30 seconds, then spit it out without swallowing. Repeat as often as it helps. Children should not rinse this way, since the risk of swallowing the solution outweighs the benefit, and an aggressive swish does more harm than a gentle one.
Does a Cold Compress or a Warm Compress Help a Toothache?
A cold compress helps a toothache and a warm compress usually makes it worse. This is the step people most often get backwards, and getting it right changes how the next few hours feel.
Cold narrows the blood vessels in the area, which reduces swelling and slows the throbbing that comes from blood pulsing into inflamed tissue. It also numbs the surface nerves slightly. Hold an ice pack or a cloth-wrapped cold pack against the outside of your cheek over the sore tooth for about 15 to 20 minutes at a time, with breaks in between, and never put ice directly on the skin.
Heat does the opposite. It dilates blood vessels and increases blood flow into a space that already has too much pressure in it, which usually sharpens the pain. Heat is useful for sore jaw muscles and for swelling that has already peaked after a procedure, and it is the wrong tool for an inflamed tooth.
What Kills Tooth Nerve Pain?
Anti-inflammatory pain relievers work best for tooth nerve pain, because the pain comes from inflammation and pressure rather than from the surface of the tooth. The 2024 American Dental Association clinical practice guideline on acute dental pain recommends nonsteroidal anti-inflammatory drugs, alone or combined with acetaminophen, as first-line therapy, with opioids reserved for cases where that falls short or cannot be used.
The reasoning matches the biology. Nerve pain in a tooth is driven by inflamed pulp tissue pressing against rigid walls, so a medication that reduces the inflammation addresses the actual mechanism, while a medication that only blunts pain perception leaves the pressure untouched. That is why the strongest option on the shelf is not always the most effective one for this particular job.
Follow the directions on the package and whatever your dentist or physician has told you about your own medical history. The guideline also makes a second point that matters more than the first: medication is explicitly a bridge to definitive dental treatment rather than a substitute for it. Nothing you take at home removes decay, seals a crack, or drains an abscess.
Why Isn't Ibuprofen Helping My Toothache?
Ibuprofen stops helping a toothache when the pressure inside the tooth has built past what an anti-inflammatory can reach, which usually means the pulp is dying or an abscess has formed. This is one of the most useful signals in all of dentistry, and almost nobody is told to watch for it.
Four explanations cover most cases. The inflammation has progressed to irreversible pulpitis, where the tissue inside the tooth is dying and the pressure keeps climbing. An abscess has formed at the root tip, which is a contained infection that no oral medication drains. The dose timing has slipped, and pain that is allowed to peak is far harder to bring back down than pain caught early. Or the source is not the tooth at all, with sinus pressure being the common impostor for upper back teeth.
Treat failure of over-the-counter relief as information rather than as a reason to take more. A toothache that no longer responds to medication that was working yesterday has changed, and it is one of the specific triggers for emergency dental care rather than another night of waiting.
Why Does a Toothache Hurt More at Night?
A toothache hurts more at night because lying down increases blood pressure in your head, which raises the pressure inside the inflamed tooth. The tooth has not changed. Your position has.
Blood flow to the head increases when you are horizontal, and in a tooth with nowhere for swelling to expand, that extra pressure translates directly into throbbing. The effect is immediate enough that many people notice the pain rising within minutes of getting into bed and easing again when they sit up.
Two other factors compound it. Distraction disappears at night, so pain that was background noise during a busy day becomes the only thing in your attention. Many people also take their last dose of pain relief hours before sleeping and then wake as it wears off. Both are fixable with planning rather than with stronger medication.
How Do You Sleep with a Toothache?
You sleep with a toothache by propping your head up on extra pillows, timing your last dose of pain relief close to bedtime, and applying cold before you lie down. Elevation does most of the work, and it costs nothing.
Stack pillows so your head sits clearly above your heart, or sleep in a recliner if that is easier. Keep the sore side facing up rather than pressed into the pillow. Apply a cold compress for a final interval shortly before bed, since reducing swelling before you go horizontal gives you a better starting point.
A few evening habits help as well. Skip alcohol, which dilates blood vessels and can increase throbbing. Avoid hot drinks and very cold ones, both of which provoke an exposed nerve. Rinse with warm salt water before bed to clear anything that would otherwise sit against the tooth for eight hours. None of this is a cure, and together it is often the difference between a rough night and no sleep at all.
Does Clove Oil Work for a Toothache?
Clove oil provides mild temporary numbing for a toothache, because it contains eugenol, a compound with genuine anesthetic and antiseptic properties. Dentistry has used eugenol in temporary filling materials for well over a century, so the folk remedy has a real basis.
Apply it carefully if you use it. Put a small amount on a cotton swab or a cotton ball, dab it onto the sore tooth, and keep it off the surrounding gum and tongue, since undiluted clove oil irritates soft tissue. The effect is modest and short, usually lasting under an hour, and it works best on a tooth with exposed dentin rather than on a deep abscess.
Keep its limits in view. Clove oil numbs a surface and does nothing about pressure inside a tooth or an infection at the root. It is a reasonable addition to the other steps and a poor replacement for any of them.
Can You Put Aspirin on a Sore Tooth?
No, you should never place aspirin directly on a sore tooth or the gum beside it, because it causes a chemical burn to the soft tissue. This remedy has been passed down for generations and it is actively harmful.
Aspirin is acidic. Held against the gum, it damages the tissue it touches, producing a white burned patch that is painful in its own right and takes time to heal. The patient then has two problems instead of one, and the original toothache is unchanged, since aspirin works through the bloodstream rather than through contact.
The same caution applies to any pill or powder crushed onto the gum, and to topical numbing gels used far beyond their label directions. Swallow oral medication as directed, and keep anything meant for the mouth surface limited to products designed for it.
What Should You Not Do with a Toothache?
With a toothache, you should not apply heat, place medication on the gum, chew on the sore side, or wait for it to resolve on its own. Avoiding the wrong moves matters nearly as much as making the right ones.
Do not put aspirin or crushed pills on the gum, which burns the tissue without reaching the tooth.
Do not apply heat to your cheek, since it increases blood flow into an area that already has too much pressure.
Do not chew on the painful side, which loads a tooth that may be cracked and drives the crack further.
Do not eat or drink anything very hot, very cold or sugary, all of which provoke an exposed nerve directly.
Do not poke at the tooth with a toothpick, pin or any sharp object, which damages gum tissue and can push debris deeper.
Do not smoke, which reduces blood flow to the healing tissue and worsens most dental problems.
Do not stop brushing, since keeping the area clean helps even when it is tender. Use a soft brush and a light touch.
Do not assume silence means it resolved, which is the one that costs people teeth.
That last point deserves its own section, and it is coming. It is the single most common reason a manageable problem turns into an urgent one.
How Long Should You Have a Toothache before Seeing a Dentist?
You should see a dentist if a toothache lasts more than one to two days, and sooner if it is severe or comes with swelling or fever. Two days is the widely used threshold and it is a ceiling rather than a target.
Several situations shorten that window considerably. Pain that wakes you from sleep, pain that no longer responds to over-the-counter relief, swelling in the face or jaw, fever, a bad taste or discharge, pain when biting down, and a tooth that was recently injured all warrant a call the same day. Waiting through any of those is where small problems become big ones.
The cost of waiting shows up in national numbers. There were more than 2 million dental-related emergency department visits in the United States in 2018, accounting for 1.4% of all ED visits, and 95% of those patients were discharged without definitive treatment because hospitals are not set up to fix teeth. Abscesses and dental caries accounted for nearly 80% of dental-related emergency room visits. Nearly all of that is preventable with an earlier dental appointment. Checking what your dental coverage includes before you need it removes one more reason to delay.
Where you go matters as much as when. If your own dentist cannot see you quickly, knowing the difference between walk-in options is worth sorting out in advance rather than at 9pm with a swollen jaw.
Will a Rotten Tooth Eventually Stop Hurting?
Yes, a rotten tooth will eventually stop hurting, and that is a warning sign rather than a recovery. This is the most important thing in this article and the thing almost nobody is told.
Here is what happens. Decay reaches the pulp, the living tissue inside the tooth containing the nerve and blood supply. The pulp becomes inflamed, which is the severe stage of the toothache. If it is not treated, the pulp dies. A dead nerve cannot send pain signals, so the pain stops, sometimes over a day or two, and the relief feels like the problem resolved itself.
The problem did not resolve. The dead tissue inside the tooth is now a sealed pocket of bacteria with no blood supply and no immune access, and the infection works its way out through the root tip into the surrounding bone. That is how an abscess forms, and the pain that returns weeks or months later is usually far worse than the original toothache, often with facial swelling attached. Patients in Cinnaminson regularly tell us the tooth "stopped bothering them last spring," which is precisely the history that explains the X-ray in front of us. A tooth that hurt and then went quiet is worth an urgent dental visit rather than a wait-and-see.
How Do You Tell If Tooth Pain Is an Infection?
You can tell tooth pain is an infection when it comes with swelling, fever, a bad taste or discharge, a tooth that feels raised when you bite, or pain that throbs constantly rather than responding to a trigger. Ordinary sensitivity behaves differently from infection, and the distinction is usually clear once you know what to compare.
Sensitivity reacts and then settles. Cold or sweet food triggers a sharp jolt that fades within seconds once the trigger is gone. Infection does not need a trigger. It throbs on its own, often continuously, and frequently worsens at night or when you lie down. A tooth that feels taller than its neighbors when you bite indicates pressure building at the root tip.
Certain signs mean the infection is no longer contained to the tooth, including facial or jaw swelling, fever, swollen glands in the neck, and feeling generally unwell. Swelling near the eye or spreading into the neck, or any difficulty breathing, swallowing or speaking, is a medical emergency rather than a dental appointment. We cover where that line sits in detail in our post on when a toothache becomes a dental emergency.
Can Your Body Fight Off a Tooth Infection by Itself?
No, your body cannot fight off a tooth infection by itself, because the inside of a tooth has no blood supply once the pulp has died. Immune cells travel through blood, and they cannot reach a chamber that no longer has circulation.
This is what makes dental infections different from most infections. A cut on your arm heals because blood carries immune cells and antibiotics straight into the tissue. Inside a dead tooth, bacteria multiply in a space your immune system has no route into, which is why the infection persists indefinitely and why it keeps seeding the bone at the root tip.
Symptoms can come and go, which fuels the confusion. Swelling rises and falls, pain flares and quiets, and each quiet spell feels like the body winning. What is actually happening is that pressure builds until it finds a release, drains partially, and then builds again. The underlying infection is unchanged throughout.
What Actually Clears an Infection in a Tooth?
Dental treatment clears an infection in a tooth, by removing the infected tissue through root canal therapy or by removing the tooth entirely. Antibiotics help control an infection that is spreading, and they do not cure the source.
American Dental Association guidance on dental pain and swelling emphasizes definitive dental treatment over antibiotics for localized infections where treatment is available, precisely because the medication cannot reach the dead space inside the tooth. Antibiotics are added when the infection has moved into the surrounding tissue, signaled by facial swelling, fever or malaise, and they work alongside the procedure rather than instead of it.
Salt water deserves a direct answer here too, since the question comes up constantly. Salt water does not draw an infection out of a tooth. It cleans the surface, soothes irritated gum tissue, and helps with debris, and it has no access to the root. Where the tooth can be kept, root canal treatment has strong long-term results, with research putting tooth survival at 97% after ten years, which is why the conversation about saving a tooth comes before any discussion of removing it.
What Will a Dentist Do for a Toothache?
A dentist will examine the tooth, take an X-ray to find the cause, and treat the specific problem, which usually means a filling, a crown, root canal therapy, a cleaning, or removal. The treatment depends entirely on the diagnosis, and the X-ray usually settles it within minutes.
Likely causeUsual treatmentWhen relief typically arrivesWithout treatmentCavity reaching dentinFillingWithin a day or twoDecay reaches the pulp and pain intensifiesDeep decay reaching the pulpRoot canal therapy, then a crownOften immediately after the appointmentPulp dies, abscess formsCracked toothCrown, or root canal and crownWithin daysCrack spreads below the gumlineAbscess at the rootDrainage plus root canal or extractionUsually within hours of drainageInfection spreads into bone and soft tissueGum infection around the rootDeep cleaning and periodontal therapyOver one to two weeksBone loss and eventual tooth looseningLost filling or crownReplacement restorationSame visitExposed dentin decays quicklyFood impactionCleaning the area, checking the contact pointImmediatelyGum inflammation and localized bone loss
Two things stand out in that table. Relief usually arrives quickly once the cause is addressed, which is the opposite of what most people fear when they delay. And the right-hand column is the real argument, since every row ends somewhere worse than it started. The specific causes behind each row are covered more fully in our post on what causes tooth pain.
None of these treatments is exotic. Fillings, crowns, cleanings and root canal therapy are routine general dentistry, done under local anesthetic, and most of them finish in a single appointment.
What to Do When a Toothache Becomes Unbearable
When a toothache becomes unbearable, call a dental office immediately rather than waiting for business hours, and go to an emergency room if there is swelling near your eye or neck or any difficulty breathing or swallowing. Pain at that level has passed the point where home care is the right answer.
Most practices keep room for urgent cases and many have an after-hours number on the answering message. While you arrange to be seen, keep up the cold compress, stay upright, take your pain relief on schedule rather than waiting for the peak, and rinse gently with warm salt water. Those steps hold the line without fixing anything, which is exactly what they are for at this stage.
Two situations skip the dental office entirely. Swelling that is spreading toward the eye or down into the neck, and any difficulty breathing, swallowing or speaking, both mean the hospital. Those are uncommon and they are genuine emergencies. Knowing what qualifies as after-hours care versus a hospital trip takes the guesswork out of a decision nobody wants to make at 2am.
Everything short of those two situations belongs in a dental chair rather than a waiting room. We keep time open each day for a same-day appointment precisely because this is the point at which people need one.
Frequently Asked Questions
Can a Toothache Go Away on Its Own?
A toothache can go away on its own, and in most cases the cause does not go away with it. Minor irritation from trapped food or temporary sensitivity after dental work genuinely resolves. Pain from decay or infection stops when the nerve inside the tooth dies, which ends the symptom while leaving an infected tooth behind. Any toothache that lasted more than a day deserves an examination even after the pain stops.
Does a Toothache Always Mean a Cavity?
A toothache does not always mean a cavity. Cracked teeth, lost fillings, gum infection around a root, exposed roots from recession, clenching and grinding, sinus pressure on upper back teeth, and food wedged between two teeth all produce similar pain. An X-ray and an examination distinguish them, which is why self-diagnosis tends to be unreliable even when the pain is clearly real.
Does Salt Draw Out an Infection in a Tooth?
Salt does not draw out an infection in a tooth. A salt water rinse cleans the surface, reduces inflammation in the surrounding gum tissue, and helps flush away debris, all of which is useful. It cannot reach inside the tooth or the bone at the root tip, where the infection actually sits. Rinsing is supportive care alongside treatment rather than a treatment itself.
What Does It Mean If a Dead Tooth Hurts?
A dead tooth that hurts usually means the infection has spread beyond the tooth into the bone and tissue at the root tip, where there are living nerves to feel it. The tooth itself has no sensation left. Pain returning after a period of silence is one of the clearest signs that an abscess has developed, and it warrants prompt evaluation rather than another round of over-the-counter relief.
How Long Will a Tooth Hurt before the Nerve Dies?
A tooth with irreversible inflammation typically hurts for several days to a few weeks before the nerve dies, though the range varies widely with the person and the cause. The pain often intensifies before it stops. Treating the tooth during that window usually means root canal therapy can save it, while waiting until the pain ends often means dealing with an abscess later instead.
The Bottom Line
Fixing a toothache has two halves. At home, rinse with warm salt water, clear trapped food with gentle flossing, hold cold against the outside of your cheek in 15 to 20 minute intervals, take over-the-counter pain relief as directed, and sleep with your head raised. Skip the heat, keep aspirin off your gum, chew on the other side, and keep brushing gently. Those steps control pain well, and they control nothing else.
The other half is timing. See a dentist if pain lasts more than one to two days, and sooner for swelling, fever, pain that wakes you, or pain that stops responding to medication that was working. Above all, do not read silence as recovery. A rotten tooth stops hurting when the nerve dies, and what follows that quiet stretch is usually an abscess that is harder and more involved to treat than the original problem would have been.
