A toothache during pregnancy can make falling asleep feel impossible, but a combination of safe pain relief, simple positioning changes, and home remedies can help you get through the night. The key is managing inflammation and pain with pregnancy-safe options while planning to see a dentist as soon as possible.
Take Acetaminophen Before Bed
Acetaminophen (Tylenol) is the go-to pain reliever during pregnancy. A dose of 325 to 650 mg every four to six hours is considered safe, with a maximum of 3,000 mg per day. Taking a dose about 30 minutes before you plan to lie down gives it time to start working.
Ibuprofen (Advil, Motrin), naproxen (Aleve), and aspirin are not safe for dental pain during pregnancy. These medications can affect fetal development and, later in pregnancy, interfere with labor. Stick with acetaminophen unless your provider has specifically told you otherwise.
Home Remedies That Help at Night
A warm saltwater rinse right before bed can reduce bacteria around the painful tooth and calm inflamed gums. Mix one and a half teaspoons of salt into eight ounces of warm water, swish gently for 30 seconds, and spit. You can do this up to three times a day safely.
Applying a cold compress to the outside of your cheek for 15 to 20 minutes can numb the area and reduce swelling. Wrap ice or a frozen gel pack in a cloth so it doesn’t irritate your skin. Cold works especially well right before bed because it temporarily dulls nerve signals from the tooth.
Clove oil is a traditional toothache remedy that works as a mild topical anesthetic. No formal pregnancy safety studies exist for clove oil, though isolated reports of women using small amounts on a painful tooth during pregnancy have shown no evidence of harm. If you want to try it, dab a tiny amount onto a cotton ball and hold it against the tooth briefly. Benzocaine gels like Orajel have also not been well studied in pregnancy, and the FDA has flagged benzocaine for a rare but serious blood disorder, so clove oil in small amounts is a reasonable alternative.
Sleep Position and Elevation
Lying flat increases blood flow to your head, which raises pressure around an inflamed tooth and intensifies throbbing pain. Propping your head and upper body up with an extra pillow or two keeps blood from pooling in the area and often makes a noticeable difference. If you’re in the second or third trimester, you’re likely already sleeping on your side. Adding elevation to a left-side position gives you the benefits of both reduced tooth pain and better circulation for the baby.
Try to avoid sleeping on the same side as the painful tooth. Pressure from the pillow against your jaw can aggravate the nerve. If the toothache is on your right side, sleeping on your left with your head elevated is the most comfortable combination.
What to Avoid Before Bed
Hot drinks, ice-cold water, and sugary snacks right before sleep can all trigger or worsen tooth pain. If you have a cavity or a cracked tooth, temperature extremes hit exposed nerve endings directly. Brush gently with a soft-bristled toothbrush and lukewarm water, and skip mouthwashes containing alcohol, which can dry out and irritate already sensitive tissue.
Breathing through your mouth while sleeping also exposes a painful tooth to air, which can trigger sharp pain. If congestion is forcing you to mouth-breathe, a saline nasal spray before bed may help you keep your mouth closed through the night.
Getting Dental Care During Pregnancy
These nighttime strategies are meant to bridge the gap until you can see a dentist. The second trimester (weeks 13 through 24) is the safest and most comfortable window for dental procedures. Organogenesis is complete by then, and you’re not yet large enough for lying in a dental chair to be uncomfortable. Routine dental work is also safe in the early third trimester but is typically avoided after about 32 weeks.
If you’re in your first trimester, dentists generally limit treatment to cleanings and emergencies only. But a genuine toothache counts as an emergency in any trimester. Standard dental anesthetics, specifically lidocaine with epinephrine, are safe throughout pregnancy. The American College of Obstetricians and Gynecologists has stated that no currently used dental anesthetics have teratogenic effects at standard doses at any gestational age. Multiple clinical studies confirm that dental treatment during pregnancy does not increase the risk of fetal problems. Don’t delay care out of fear that numbing injections will harm the baby.
Signs That Need Urgent Attention
Most pregnancy toothaches are manageable overnight, but certain symptoms signal a dental infection that can become dangerous. Facial swelling, fever, difficulty opening your mouth, or trouble swallowing all point to a possible abscess that’s spreading. A systematic review of severe dental infections during pregnancy found serious consequences when infections went untreated: fetal death occurred in 13% of cases, fetal distress in nearly 6%, and preterm birth in over 4%. Maternal death occurred in about 6% of the most severe cases reviewed.
These numbers reflect infections that were allowed to progress without treatment, not routine toothaches. The takeaway is straightforward: if your toothache comes with swelling, fever, or any sign of spreading infection, get care that night rather than waiting for a morning appointment. Emergency dental treatment is safe at every stage of pregnancy.
