Sleeping with a toothache is difficult because lying down increases blood flow to your head, which amplifies the throbbing pressure around an inflamed tooth. The good news: a combination of the right pain relief, simple home remedies, and a few adjustments to how you position yourself can get you through the night. Here’s what actually works.
Take Pain Relief Before You Lie Down
The most effective over-the-counter approach for dental pain is taking ibuprofen and acetaminophen together. This combination outperforms either drug alone because they work through different mechanisms: ibuprofen reduces inflammation at the tooth while acetaminophen blocks pain signals more centrally. A typical regimen is 400 mg of ibuprofen combined with 500 to 1,000 mg of acetaminophen, taken together every six hours. This gives you a solid window of relief that can last most of the night.
Time your dose about 30 minutes before you plan to fall asleep so the medications are fully active when you’re trying to drift off. If you wake up in pain partway through the night, you can take another round as long as six hours have passed. Avoid aspirin if the tooth area is bleeding, since it thins the blood and can make things worse.
Elevate Your Head
Lying flat is one of the main reasons toothaches feel worse at night. When your head is level with your heart, more blood pools in your head and increases pressure on the already-irritated nerve. Prop yourself up with an extra pillow or two so your head stays above your chest. You don’t need to sleep sitting upright, just enough of an incline that you notice the throbbing ease up. A wedge pillow works well if you have one, but stacking regular pillows is fine.
Use a Cold Compress on Your Cheek
A cold compress applied to the outside of your cheek, on the side of the toothache, numbs the area and reduces inflammation. Hold it against your face for 10 to 15 minutes at a time, then remove it for at least the same amount of time before reapplying. Don’t exceed 20 minutes continuously, as that can damage the skin. Wrap the ice pack in a thin cloth rather than pressing it directly against your face.
You can cycle through a few rounds of this while you’re winding down for bed. Some people find it helpful to do one last round right as they’re about to close their eyes, so the numbing effect carries them into sleep.
Try Clove Oil for Targeted Numbing
Clove oil contains a natural compound called eugenol that works as both a pain reliever and a mild anesthetic. It blocks inflammatory signals and activates certain nerve channels that reduce pain perception. In clinical testing, clove oil applied directly to oral tissue provided pain reduction comparable to ice, and the FDA has classified eugenol as generally recognized as safe for human use.
To use it, put a small drop of clove oil on a cotton ball and hold it gently against the sore tooth and surrounding gum for a minute or two. The taste is strong and slightly spicy, but most people tolerate it without any burning or irritation. You can find clove oil at most pharmacies, often in the dental care aisle. Don’t swallow it, and use only a small amount.
Rinse With Warm Salt Water
A saltwater rinse before bed helps clean the area around the painful tooth, drawing out some fluid from inflamed tissue and creating an environment that’s harder for bacteria to thrive in. Mix 1 teaspoon of salt into 8 ounces of warm water until it dissolves, swish it gently around your mouth for up to 30 seconds, and spit it out. If the mixture feels too harsh, cut back to half a teaspoon. This won’t fix the underlying problem, but it can reduce irritation enough to make the pain more manageable as you settle in.
Avoid Foods and Drinks That Make It Worse
What you eat and drink in the hours before bed can either calm or aggravate a toothache. Acidic foods and beverages are the biggest culprits. Citrus fruits, tomatoes, carbonated drinks (even sugar-free ones), sports drinks, and anything sour all increase acid levels in your mouth and can intensify sensitivity and nerve pain. Sticky foods like dried fruits cling to teeth and prolong acid exposure from cavity-causing bacteria.
Very hot or very cold foods can also trigger sharp pain if the nerve is exposed or inflamed. Stick to lukewarm, soft, neutral foods for your evening meal. Avoid eating on the side of the toothache entirely if you can. Skip the bedtime tea with lemon or the late-night orange juice, both of which are more acidic than they seem.
Check Whether You’re Clenching Your Jaw
Many people clench or grind their teeth during sleep without realizing it, a condition called sleep bruxism. This puts significant force on your teeth, the surrounding bone, and the jaw joint, and it can turn a mild toothache into a severe one by morning. Common signs include waking with jaw soreness, a dull headache around the temples, or noticing that your teeth feel tender first thing in the morning.
If you suspect you grind your teeth, try to consciously relax your jaw before falling asleep. Rest your tongue lightly on the roof of your mouth with your teeth slightly apart. Over-the-counter mouthguards exist, but the soft vinyl versions can actually increase muscle activity in some people and make jaw pain worse. A hard acrylic splint fitted by a dentist is more effective for long-term management, though that’s not a tonight solution. For now, focusing on jaw relaxation and sleeping on your back (to avoid pressing one side of your face into the pillow) can help.
What About Numbing Gels?
Over-the-counter benzocaine gels (sold under brand names like Orajel) can temporarily numb the gum tissue around a painful tooth. They work within a minute or two and can provide short-term relief. However, benzocaine carries a serious safety warning from the FDA: it can cause a rare but life-threatening condition called methemoglobinemia, where the blood’s ability to carry oxygen drops significantly. This risk is low in adults using the product as directed, but it’s worth knowing. Never use benzocaine products on children under 2 years old, and follow the label directions carefully. Don’t apply it more frequently than instructed, and don’t use large amounts to try to get stronger relief.
Signs You Need Emergency Care
A toothache that keeps you up one night is usually something you can manage until you get a dental appointment. But certain symptoms mean the problem has escalated beyond home care. Swelling in your face or jaw can signal a dental abscess, an infection that can spread to other parts of your body if left untreated. Bleeding that won’t stop despite pressure, pain that doesn’t respond at all to medication, fever, or difficulty breathing or swallowing are all reasons to go to an emergency room rather than waiting for a regular dental visit.
Even without those red flags, a toothache that persists more than a day or two needs professional attention. The strategies above are designed to get you through the night, not replace treatment. The underlying cause, whether it’s a cavity, a crack, an infection, or gum disease, will keep producing pain until it’s addressed.
