A toothache that flares up at night can feel significantly worse than it did during the day, and that’s not your imagination. When you lie down, blood flow to your head increases because your head is at the same level as your heart. That extra pressure around your jaw and teeth amplifies pain signals from any area that’s already inflamed or damaged. The good news: several strategies can reduce that pain enough to get you through the night until you can see a dentist.
Why Toothaches Get Worse at Night
During the day, gravity keeps blood flowing downward, away from your head. The moment you lie flat, blood rushes toward your face, mouth, and sinuses. This increased circulation puts pressure on the sensitive tissue inside a painful tooth, intensifying discomfort that may have been manageable just hours earlier.
There’s also a distraction factor. During the day, work, conversation, and activity compete for your brain’s attention. At night, in a quiet room with nothing else to focus on, pain signals become harder to ignore. Cortisol, your body’s natural anti-inflammatory hormone, also dips to its lowest levels in the late evening, which can reduce your built-in pain buffering.
Elevate Your Head While You Sleep
Since lying flat is a major reason the pain spikes, propping yourself up is the simplest first step. Stack an extra pillow or two so your head stays above your heart. This reduces blood pooling around your jaw and can noticeably lower the throbbing sensation. It won’t fix the underlying problem, but it removes the positional trigger that makes nighttime pain worse than daytime pain.
Combine Pain Relievers for Stronger Relief
For dental pain, taking ibuprofen and acetaminophen together is more effective than either one alone. Research on post-surgical dental pain found that combining the two at moderate doses provided relief comparable to taking 400 mg of ibuprofen by itself, and the combination works through two different mechanisms: ibuprofen reduces inflammation at the tooth, while acetaminophen blunts pain signals in the brain.
The maximum effective single doses are 400 mg for ibuprofen and 1,000 mg for acetaminophen. Going higher than those amounts doesn’t add pain relief but does increase the risk of side effects. If you prefer to alternate instead of combining, you can take one, then the other three hours later, so you’re getting a dose of something every few hours through the night. Avoid ibuprofen on an empty stomach, since it can irritate the lining of your digestive tract.
Try a Salt Water Rinse
A warm salt water rinse can reduce bacteria around an infected or inflamed tooth and draw out some of the fluid causing swelling. Mix one teaspoon of salt into eight ounces of warm water. Swish it gently around the painful area for 30 seconds, then spit. You can repeat this several times. If your mouth is very tender, start with half a teaspoon of salt and work up. The warmth itself can be soothing, and the salt creates an environment that’s hostile to bacteria.
Apply Clove Oil to the Tooth
Clove oil contains a compound called eugenol, which makes up 70 to 90 percent of the oil and acts as a natural anesthetic and anti-inflammatory. It temporarily numbs the nerve endings in the affected area. 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 into the mixture and hold it against the painful tooth for a few minutes. Undiluted clove oil can irritate your gums, so don’t skip the dilution step. If you’ve never used clove oil before, do a small patch test on your inner wrist first to check for an allergic reaction.
Use Numbing Gels Carefully
Over-the-counter oral numbing gels containing benzocaine can provide temporary relief when applied directly to the gum around a painful tooth. However, the FDA has issued warnings about benzocaine: it can cause a rare but serious condition called methemoglobinemia, which reduces the blood’s ability to carry oxygen. These products should never be used on children under two years old. For adults and older children, follow the label directions exactly and use the smallest amount needed. Don’t reapply more frequently than the packaging allows.
Avoid Certain Foods Before Bed
What you eat in the evening can make a nighttime toothache worse. Acidic foods like citrus fruits, tomatoes, pickles, and tea erode the protective outer layer of your teeth, exposing the sensitive layer underneath. Very hot, very cold, or sugary foods and drinks can also trigger sharp pain in a tooth that’s already compromised. If you’re dealing with a toothache, stick to lukewarm, neutral foods in the hours before bed. Brush gently afterward, but avoid aggressive brushing near the painful area, which can further irritate exposed tissue.
Check for Teeth Grinding
If your toothache is concentrated in your back teeth or you wake up with jaw soreness, nighttime teeth grinding (bruxism) could be contributing. Grinding puts enormous pressure on your teeth for hours while you sleep, which can crack enamel, inflame nerves, and cause headaches and facial pain. A mouth guard creates a barrier between your upper and lower teeth. Store-bought versions are available at most pharmacies and can offer some immediate protection, though they’re less effective than custom-fitted guards from a dentist. If a store-bought guard doesn’t fit well, it can actually cause additional soreness in your teeth and gums, so pay attention to how it feels.
Cold Compress on the Outside
Wrapping ice or a cold pack in a thin towel and holding it against your cheek for 15 to 20 minutes can numb the area and reduce swelling. Cold constricts blood vessels, which counteracts the increased blood flow that comes with lying down. Take breaks between applications to avoid irritating your skin. This works especially well alongside oral pain relievers, since it targets the inflammation from the outside while medication works from the inside.
Signs You Need Emergency Care
Most toothaches, while miserable, can wait until the next available dental appointment. But certain symptoms signal a spreading infection that needs immediate attention. Go to an emergency room if you experience any of the following alongside your toothache:
- Fever of 100.4°F (38°C) or higher
- Swelling in your face, jaw, neck, or around your eyes
- Difficulty breathing or swallowing
- Severe pain that doesn’t respond to maximum doses of over-the-counter painkillers
- Trouble opening your mouth or handling saliva
These can indicate a dental abscess that’s spreading beyond the tooth. An untreated abscess can become dangerous quickly, particularly if swelling begins to compromise your airway or spread to the floor of your mouth. If a dentist isn’t available, a hospital emergency department can start treatment to control the infection.
