What Can You Do for Severe Tooth Pain at Home?

Taking ibuprofen and acetaminophen together is the single most effective thing you can do at home for severe tooth pain, outperforming either drug alone and even some prescription combinations. Beyond that core strategy, a handful of topical treatments, cold therapy, and rinses can provide additional short-term relief while you arrange to see a dentist. None of these measures fix the underlying problem, but they can make the hours or days before professional treatment far more bearable.

Why Tooth Pain Can Be So Intense

The inside of a tooth contains a soft tissue called the pulp, which is packed with nerve fibers whose primary job is detecting damage. Unlike nerves in many other body parts, pulp nerves are almost exclusively dedicated to pain signaling rather than touch or temperature in a useful sense. When decay, a crack, or infection reaches the pulp, those fibers fire aggressively, and the resulting pain can radiate across an entire side of your face.

What makes dental pain especially hard to ignore is that the pulp sits inside a rigid shell of hard tooth. When inflammation causes swelling in soft tissue like a sprained ankle, the tissue expands. Inside a tooth, there is nowhere to expand. Pressure builds against the nerve fibers, and the pain intensifies. Inflammatory chemicals like substance P flood the area and keep the pain cycle going even after the original trigger stops.

The Best Over-the-Counter Pain Strategy

If you have both ibuprofen and acetaminophen (sometimes labeled as paracetamol or by brand names like Tylenol and Advil) in your medicine cabinet, you already have the strongest non-prescription pain relief available for a toothache. Multiple randomized trials after wisdom-tooth removal have consistently found that the two drugs taken together provide greater and faster pain relief than either one alone or placebo.¹ The combination also outperformed codeine-containing analgesics in one head-to-head trial, which is striking because codeine formulations are prescription-only in many countries.²

The reason this pairing works so well is that the two drugs reduce pain through different pathways. Ibuprofen is an anti-inflammatory, so it directly tackles the swelling inside or around the tooth. Acetaminophen works more centrally on pain perception in the brain. By hitting pain from two angles, the combination covers more ground than doubling down on either drug alone. A review of several randomized controlled trials confirmed that side effects from the combination were no worse than those of each drug taken individually, so there is no extra safety cost to combining them at standard doses.³

A common approach is to take 400 mg of ibuprofen and 500–1,000 mg of acetaminophen at the same time, repeating every six to eight hours. Do not exceed the daily maximum for either drug (typically 1,200 mg of ibuprofen and 3,000–4,000 mg of acetaminophen for most adults, though lower limits apply if you have liver or kidney issues). If you can only get one of the two, ibuprofen is generally the better single choice for dental pain because it addresses the inflammatory component directly.

Topical Numbing Gels

Over-the-counter benzocaine gels, sold under brand names like Orajel, can take the edge off while you wait for oral painkillers to kick in. In a clinical trial of patients with acute toothaches, benzocaine gel applied directly to the painful area significantly outperformed a placebo gel, with the higher-strength 20 percent formulation working better than 10 percent.⁴ An earlier study found that about 83 percent of patients who received benzocaine experienced pain relief, with an average onset of under four minutes.⁵

The relief from benzocaine is genuinely temporary. It numbs the surface tissue for roughly 15 to 30 minutes, then fades. Think of it as a bridge to get you through until ibuprofen and acetaminophen take effect, not as a standalone solution. Reapply as directed on the packaging, and avoid eating on that side of your mouth right after application since you could bite your cheek or tongue without feeling it.

One important caution: benzocaine products labeled for adults should not be used on children under two years old. The FDA has warned about a rare but serious blood condition called methemoglobinemia linked to benzocaine use in very young children. For older children and adults at standard doses, the risk is extremely low. The clinical trial of benzocaine for toothaches reported zero cases of this condition.⁴

Cold Packs and Their Limits

Holding a cold pack against your cheek on the painful side is one of the oldest pieces of toothache advice, and there is a plausible reason it might help. Cold reduces blood flow and slows nerve conduction, which can blunt pain signals and limit swelling.⁶ A review of home remedies for dental pain classified cryotherapy as one of the interventions with the strongest scientific backing for emergency use.⁷

That said, the evidence is more mixed than you might expect. A randomized trial looking at cold therapy after surgical tooth removal found no significant difference in pain, swelling, or jaw stiffness between the cold therapy side and the control side.⁸ Post-surgical pain is not exactly the same as a raging toothache from an infected nerve, so this trial does not settle the question entirely. Still, it suggests that cold therapy’s benefits for dental pain are modest at best. It may take the edge off, and it certainly will not hurt if you keep sessions short (10 to 15 minutes at a time with a cloth barrier to avoid skin damage), but do not expect it to replace medication.

Salt Water Rinses

A warm salt water rinse is cheap, easy, and reasonably effective as a supportive measure. Dissolve about half a teaspoon of table salt in a cup of warm water and swish it gently around the painful area for 30 seconds before spitting it out. Salt water creates an osmotic environment that is hostile to bacteria and can help draw out some fluid from swollen tissue, reducing pressure.

Salt water gargling is one of the traditional remedies that has been used for centuries and does have some empirical support, though the scientific evidence is relatively weak compared to pharmaceutical options.⁷ It is not going to eliminate severe pain on its own, but as an add-on to ibuprofen and acetaminophen, it is a reasonable step, especially if you suspect infection and want to keep the area as clean as possible between brushings.

Clove Oil and Eugenol

Clove oil has been used for toothaches for centuries, and this one is not just folklore. The active compound, eugenol, is actually used in professional dentistry as a component in temporary fillings and sedative dressings. It works by affecting calcium and chloride channels in nerve cells, which blunts pain signaling at the site.⁹

To use it at home, put a drop or two of clove oil on a small cotton ball and hold it against the painful tooth. You will feel a strong, warm, slightly numbing sensation. The taste is intense and not for everyone, but the local analgesic effect is real. You can find clove oil in most pharmacies or health food stores. Avoid flooding the area with large amounts; eugenol can irritate soft tissue at high concentrations, so a little goes a long way.

Clove oil is best thought of as a targeted topical measure for a specific tooth that you can identify as the source of pain. If the pain is diffuse or you are not sure which tooth is the problem, systemic painkillers will serve you better.

Hydrogen Peroxide Rinses

Diluted hydrogen peroxide is sometimes recommended as a mouth rinse for toothache, particularly when infection is suspected. There is reasonable evidence that low-concentration hydrogen peroxide has genuine antibacterial effects in the mouth and can reduce gum inflammation better than a placebo rinse.¹⁰ Most studies use concentrations of about 1.5 percent, which is what you get by mixing common drugstore 3 percent hydrogen peroxide with an equal amount of water.

Safety data is reassuring at these low concentrations. Studies tracking daily use of 3 percent hydrogen peroxide or less for extended periods found only occasional, minor irritation, mostly in people who already had existing mouth sores.¹¹ A separate safety review confirmed that at low concentrations used in self-administered oral health products, hydrogen peroxide does not damage oral hard or soft tissue and carries no significant risk of long-term adverse effects.¹²

Swish the diluted solution around the painful area for about 30 seconds and spit it out. Do not swallow it. Hydrogen peroxide is not a painkiller in itself, so the benefit is primarily about reducing bacterial load and inflammation. If your pain is driven by an abscess or gum infection, this may help limit how bad things get before you can see a dentist.

What Not to Put on a Toothache

Some home remedies are actively harmful. The most common mistake is placing an aspirin tablet directly on the gum next to a painful tooth. This seems logical if you know aspirin is a painkiller, but aspirin needs to be swallowed to work. Held against tissue, it acts as an acid that causes chemical burns. Case reports document epithelial necrosis and erosion of the gum tissue from this practice.¹³ The damage shows up as white, painful, eroded patches on the gum that can take days to heal, leaving you with two problems instead of one.¹⁴ If you want aspirin’s pain-relieving effects, swallow it. Better yet, reach for ibuprofen, which is a more effective anti-inflammatory for dental pain anyway.

Raw garlic is another folk remedy that can cause real injury if overdone. During the pandemic, one case report documented a 72-year-old woman who developed burns on the surface of her tongue from daily raw garlic application. She needed to stop the habit entirely and switch to a soft, non-acidic diet before the tissue healed over the course of two weeks.¹⁵ Garlic contains allicin, which has some antimicrobial properties, but in direct contact with delicate mouth tissue it acts as an irritant. If you want garlic’s potential benefits, cook with it. Do not hold raw cloves against your gums.

Alcohol, whether whiskey swished around the mouth or vodka applied on a cotton ball, is another remedy that persists despite being ineffective. The concentrations in drinking alcohol are too low to meaningfully numb tissue or kill bacteria, and alcohol dries out and irritates the mouth lining. The same goes for undiluted essential oils other than clove. Tea tree oil, peppermint oil, and oregano oil in concentrated form can all burn soft tissue.

Managing Tooth Pain in Children

Children’s tooth pain calls for a slightly different approach. The American Dental Association’s clinical practice guideline for acute dental pain in children recommends non-opioid medications as the first line, specifically ibuprofen or naproxen alone or combined with acetaminophen, similar to the adult strategy.¹⁶ Dose by weight, not by age, using the instructions on the children’s formulation packaging or your pediatrician’s guidance.

The same guideline makes one point especially worth knowing: codeine and tramadol are contraindicated in children for acute pain management, per the FDA.¹⁶ Some children metabolize codeine into morphine far too rapidly, which can cause life-threatening breathing problems. If someone offers you leftover codeine-containing painkillers for a child’s toothache, do not use them.

For topical relief in children, benzocaine gels designed for pediatric use (usually lower concentration and child-safe flavoring) are available for kids over two. Clove oil is generally considered safe in small amounts for older children but should be used sparingly and kept away from young toddlers who might swallow it. Cold packs on the cheek and warm salt water rinses are safe for any age as long as the child is old enough to swish and spit.

When Home Remedies Are Not Enough

Everything described above is a holding action. Severe tooth pain almost always signals a problem that requires professional treatment: a deep cavity, an abscess, a cracked tooth, or advanced gum disease. Home measures buy you time, but they do not address the cause. If your pain responds to ibuprofen and acetaminophen and you can get a dental appointment within a few days, you will likely be fine managing at home in the interim.

Certain signs, however, mean you should seek care urgently, potentially at an emergency room if a dentist is not available. Dental infections can spread beyond the jawbone into the spaces of the neck and face, and in rare cases this leads to airway compromise, blood clots near the brain, or infection spreading into the chest, all of which are life-threatening.¹⁷ Watch for these warning signs:

Facial swelling: Significant swelling of the cheek, jaw, or under the chin, especially if it is getting visibly worse over hours.
Difficulty opening your mouth: If you cannot open your jaw more than a finger’s width, infection may be spreading into the muscles around the jaw.
Fever with dental pain: A temperature above 101°F (38.3°C) alongside a toothache suggests the infection has moved beyond the tooth itself.
Trouble swallowing or breathing: This is the most urgent sign. Swelling in the floor of the mouth or throat can close off your airway. Go to an emergency room immediately.
Pain unresponsive to maximum OTC doses: If full doses of ibuprofen and acetaminophen together make no dent in the pain, the underlying problem is likely beyond what home care can manage.

Putting Together a Home Pain Plan

If you are dealing with severe tooth pain right now and want a practical sequence, here is what the evidence supports. Start by taking 400 mg of ibuprofen and 500 mg of acetaminophen together. While you wait the 20 to 30 minutes for them to kick in, apply a small amount of 20 percent benzocaine gel directly to the sore spot and hold a cold pack wrapped in a cloth against the outside of your cheek. Rinse gently with warm salt water or diluted hydrogen peroxide to clean the area. If you have clove oil, dab a tiny amount on a cotton ball and hold it against the tooth after rinsing.

Repeat the medication every six to eight hours as needed, staying within the daily maximum for both drugs. Between doses, you can reapply benzocaine and clove oil as needed. Keep the area clean with gentle brushing and rinsing. Avoid very hot, very cold, or very sweet foods and drinks that can trigger sharper pain spikes. Sleep with your head slightly elevated on an extra pillow, since lying flat increases blood flow to the head and can intensify throbbing.

And call a dentist. Even if the pain becomes manageable, the underlying cause will not resolve on its own. Tooth infections only worsen with time, and what starts as a treatable cavity can become a root canal or extraction if left long enough. Many dental offices keep emergency slots or can at least phone in a prescription for antibiotics if infection is the likely culprit. The home measures above are genuinely effective at making severe pain livable, but they work best as a bridge to real treatment, not as a long-term plan.
