A toothache rarely waits for a convenient time, and the fastest relief you can get at home comes from combining two common pain relievers: ibuprofen and acetaminophen taken together. Beyond that, several rinses, topical treatments, and simple positioning tricks can bring the pain down while you wait to see a dentist. Here’s what actually works and how to do each one safely.
Combine Two Pain Relievers for Stronger Relief
Taking ibuprofen and acetaminophen together is more effective for dental pain than either one alone. They work through different pathways: ibuprofen reduces inflammation at the source, while acetaminophen changes how your brain processes pain signals. The American Dental Association’s 2024 acute pain guidelines recommend non-opioid approaches like this combination as a first-line treatment for dental pain.
A combination tablet (125 mg ibuprofen and 250 mg acetaminophen) is available over the counter, dosed at two tablets every eight hours with a maximum of six tablets per day. If you don’t have the combination product, you can take standard doses of each separately. Because they’re processed by different organs, they don’t compete with each other or increase side effects when used at recommended doses. Ibuprofen works best when taken with food to protect your stomach.
Rinse With Warm Salt Water
A saltwater rinse is one of the simplest and safest things you can do immediately. Dissolve one teaspoon of salt in eight ounces of warm water, swish gently around the painful area for 30 seconds, and spit. If the rinse stings, cut the salt to half a teaspoon for the first day or two.
Salt water works through osmosis. It pulls excess fluid out of swollen gum tissue, which reduces pressure and eases pain. The same mechanism draws water out of bacteria, killing many common oral species on contact. You can repeat this rinse several times a day without any real downside, making it a good go-to between doses of pain medication.
Apply Clove Oil to the Tooth
Clove oil contains a compound called eugenol, which makes up 70% to 90% of the oil and acts as a natural anesthetic, anti-inflammatory, and antibacterial agent. It’s one of the few home remedies with a well-understood mechanism: eugenol temporarily numbs nerve endings on contact.
To use it safely, dilute a few drops of clove essential oil into a carrier oil like coconut or olive oil. Dip a cotton ball or swab into the mixture and hold it against the painful tooth for a minute or two. Don’t apply undiluted clove oil directly to your gums or soft tissues. While safe for occasional use, repeated application can irritate or damage the gum tissue, tooth pulp, and the lining of your mouth. Think of it as a short-term bridge to professional care, not a daily treatment.
Try Crushed Garlic With Salt
When garlic is crushed, it releases a compound called allicin that has antibacterial and antimicrobial properties. These can help kill some of the bacteria fueling a toothache and temporarily reduce pain. Crush a clove of garlic with the back of a spoon, mix it with a small pinch of salt, and apply the paste to the affected tooth with a clean finger or cotton swab. The salt adds its own antibacterial effect and helps draw out fluid from inflamed tissue.
The relief is mild compared to pain medication, but garlic can be useful when you’re out of other options or want something to use between doses.
Be Cautious With Hydrogen Peroxide and Numbing Gels
You may have heard of rinsing with hydrogen peroxide or applying a numbing gel containing benzocaine. Both carry risks worth knowing about.
If you use 3% hydrogen peroxide (the standard drugstore concentration), dilute it with equal parts water before swishing. Even diluted, it’s harsh on soft tissue and should only be used short-term. Some dentists advise against using it routinely as a rinse at all, so it’s best reserved for a single use when nothing else is available.
Benzocaine gels like Orajel numb the area on contact, but the FDA has issued a specific warning about a serious side effect called methemoglobinemia, a condition where the blood’s ability to carry oxygen drops dangerously low. This risk is highest in young children. Products containing benzocaine should never be used on children under two years old. For adults, follow the package directions closely and don’t reapply more often than directed.
Why Toothaches Get Worse at Night
If your tooth hurts more when you lie down, it’s not your imagination. When you’re flat, gravity allows more blood to flow into your head and neck, increasing pressure inside inflamed dental tissue. The pulp inside your tooth contains tiny blood vessels that become engorged during inflammation, and the extra blood flow creates a throbbing sensation as pressure builds against pain receptors in the enclosed pulp chamber.
The fix is simple: sleep with your head elevated on an extra pillow or two. When your head is higher than your heart, your cardiovascular system has to work against gravity to push blood upward, naturally reducing pressure in the tissues around the tooth. This won’t cure anything, but it can mean the difference between lying awake in pain and getting some sleep. Taking a dose of ibuprofen about 30 minutes before bed adds another layer of relief, since it directly targets the inflammation driving the pressure buildup.
Signs You Need Emergency Care, Not Home Remedies
Home treatments are meant to buy you time until a dental appointment. Certain symptoms mean the infection has moved beyond the tooth, and waiting becomes dangerous.
- Fever over 100.4°F: This signals the infection has spread into surrounding tissue or your bloodstream.
- Rapid facial swelling: Swelling that affects your ability to open your eye or extends down your neck needs immediate attention.
- Difficulty swallowing or breathing: A dental infection can cause swelling in the throat that compromises your airway. This is always an emergency.
- Severe pain that doesn’t respond to medication: Pain that comes on suddenly and isn’t touched by ibuprofen and acetaminophen together may indicate an abscess under pressure.
Any of these warrant an emergency room visit, not a dental office waiting list. Dental infections that spread can become life-threatening quickly, and the ER can start antibiotics and manage swelling while you arrange follow-up dental care.
