When teething strikes, many parents assume babies sleep more—but the truth is usually the opposite. Most babies actually sleep less due to gum discomfort, restlessness, and disrupted routines. However, a small number of babies might appear sleepier if they’re fighting an infection or experiencing low-grade fever. Keep reading to get the full picture and practical tips for handling teething nights.
Picture this: Your usually lively 7-month-old starts drooling like a faucet, chewing on everything in sight, and waking up every hour at night. You run a quick online search and land on the question everyone asks — do babies sleep more when teething? It’s a natural thought, because many of us feel like sleeping more when we’re in pain. But babies? They have their own way of handling things.
If you’re a tired parent desperately hoping for a magical “yes,” I’m sorry to burst your bubble. Most babies actually sleep less during teething. The sore gums, the pressure of a tooth pushing through, and the general discomfort make it harder for them to settle and stay asleep. However, a few babies might surprise you by sleeping more. Let’s dive into what’s really going on and how you can survive this phase.
Key Takeaways
- Most babies sleep less during teething: Gum inflammation and pain usually lead to more frequent night wakings, shorter naps, and overall less sleep.
- A small percentage of babies may sleep more: If your baby is fighting an illness alongside teething, extra sleep can be a sign their body is conserving energy.
- Teething alone rarely causes fever above 100.4°F (38°C): High temperature often points to an infection, not just a new tooth.
- Disrupted sleep due to teething usually lasts only a few days: Once the tooth breaks through, sleep patterns typically return to normal.
- Comfort measures can help: Cold teething rings, gentle gum massage, and a consistent bedtime routine may reduce nighttime discomfort.
- Consult your pediatrician if sleep changes persist or are accompanied by high fever, diarrhea, or extreme fussiness: These could be signs of an illness unrelated to teething.

The Teething-Sleep Connection: What Science Says
Many parents swear their baby sleeps more when teething, but research tells a different story. In a 2016 study published in Pediatrics, researchers tracked 125 babies from their first tooth eruption through the following weeks. They found that teething was linked to more nighttime awakenings, not more sleep. The symptoms—irritability, gum rubbing, drooling—peaked a few days before a tooth popped through and usually subsided quickly afterward.
So why the myth that babies sleep more? One possible reason: parents remember the exhaustion differently. After a week of broken sleep, a single good nap can feel like a “growth spurt” or “teething sleep marathon.” But on average, teething disrupts sleep rather than enhancing it.
Another factor: some babies develop a low-grade fever (under 100.4°F) when teething. Fever can make a baby drowsy, but it’s not the same as restful sleep. They may appear to sleep more because they’re lethargic from fighting inflammation, but the quality of sleep is often poor.
Why Pain Usually Means Less Sleep
Imagine trying to fall asleep with a throbbing headache or a sore muscle. That’s what a teething baby feels—constant pressure and sharp pangs as a tooth breaks through the gums. For babies, sleep is already a skill they’re learning. Adding physical pain makes self-soothing nearly impossible. They need more help from you to get comfortable, which leads to more wakings and shorter sleep cycles.
The Exception: When a Baby Might Sleep More
There is a small group of babies who do seem to sleep more during teething. Why? Often because they’re not just teething—they’re also fighting a mild illness. Teething lowers the immune system slightly, making babies more vulnerable to viruses. If your baby has a cold, an ear infection, or even a stomach bug alongside teething, their body might crave extra rest to recover. In that case, the extra sleep comes from the illness, not the tooth.
Real Reasons Your Baby’s Sleep Changes During Teething
Instead of asking “do babies sleep more when teething,” a better question is “how does teething change sleep?” Here are the most common shifts parents report:

- More frequent night wakings: Your baby may wake every 45–90 minutes crying or fussing. The discomfort peaks during lighter sleep stages, causing them to rouse.
- Shorter naps: Daytime sleep might shrink from 1.5 hours to 30 minutes because they can’t stay relaxed.
- Difficulty falling asleep at bedtime: The agitation from sore gums makes drowsiness hard to achieve.
- Increased night nursing or bottle feeds: Sucking can soothe gum pain, so your baby may want to nurse more often during the night—which further disrupts sleep for both of you.
- Restless sleep: You might notice more tossing, turning, and whimpering compared to normal.
When to Suspect Illness Instead of Teething
Many parents blame every sleep disruption on teething, but sometimes it’s something else. Signs that your baby’s sleep changes are due to an infection rather than teething include: fever above 100.4°F, diarrhea, vomiting, runny nose with colored mucus, or ear pulling that doesn’t coincide with drooling. If you see these symptoms, consult your pediatrician.
How to Survive (and Maybe Improve) Teething Sleep
Knowing that your baby will probably sleep less during teething doesn’t help your own sleep deficit. But a few strategies can reduce the suffering for everyone.
1. Provide Safe Chewing Options
Before bedtime, offer a cold (not frozen) teething ring or a chilled washcloth to gnaw on. The cold numbs the gums and provides counter-pressure. Do this 15–20 minutes before you start your bedtime routine to ease the initial discomfort.
2. Gentle Gum Massage
With a clean finger or a silicone fingertip brush, gently rub your baby’s gums. This can relieve pressure and help them relax. Be gentle—your baby’s gums are sensitive.
3. Consider Pain Relief if Needed
For severe discomfort, your pediatrician may recommend a weight-appropriate dose of acetaminophen (Tylenol) or ibuprofen (Motrin). Use these only when your baby is clearly in pain and having trouble settling. Never exceed the recommended dosage. Ibuprofen can be especially helpful because it reduces inflammation, which is the root of the pain.
4. Stick to Your Routine (But Stay Flexible)
Consistent bedtime routines are powerful anchors for babies. Keep bath, book, and lullaby even if your baby is fussy. The familiarity can be calming. However, if your baby is too agitated to lie down, don’t force it. Hold them, rock them, or give an extra feeding. A few days of variation won’t ruin sleep habits forever.
5. Offer Extra Cuddles, Not Sleep Props
It’s tempting to bring your baby into your bed or use a swing for overnight sleeping when teething hits. But try to avoid starting new sleep props that you’ll have to break later. Instead, respond promptly to cries, offer comfort in the crib, and return to the same soothing methods you use normally.
Should You Wake a Teething Baby to Feed?
This is a common question from parents of very young teething babies (4–6 months). If your baby is sleeping longer than usual during a teething episode, should you wake them to nurse? In most cases, no. If your baby is sleeping, they likely need that rest. But if they are under 4 months old and have lost weight or are not feeding well during the day, check with your pediatrician. Otherwise, let sleeping babies lie—even teething ones.
When to Call the Doctor
Most teething-related sleep disruptions last only 2–4 days per tooth. But if you notice any of the following, it’s time to call your pediatrician:
- High fever (over 100.4°F) that lasts more than 24 hours
- Your baby refuses to feed for more than 6–8 hours
- Diarrhea or vomiting persists
- Your baby seems unusually lethargic or difficult to wake
- Sleep changes continue for more than a week without a tooth appearing
These symptoms could indicate an infection, ear infection, or other illness that needs medical attention.
The Bottom Line: Do Babies Sleep More When Teething?
No, the vast majority of babies sleep less during teething. The pain, inflammation, and restlessness disrupt their sleep patterns. A few babies may appear to sleep more if they have a mild fever or are fighting an infection, but that extra sleep is usually not restorative. Understanding this can help you manage your expectations and respond to your baby’s needs without guilt. Teething is tough, but it’s temporary. Before you know it, your baby will have a mouthful of teeth—and you’ll both sleep well again.
Frequently Asked Questions
Can teething cause a baby to sleep more than usual?
It’s unusual, but yes, some babies do sleep more when teething. This often happens if they are also fighting a mild illness that makes them drowsy, or if inflammation induces a low-grade fever that causes lethargy. However, the sleep is typically not high quality, and your baby may still be restless.
How long does teething sleep disruption last?
Most babies experience disrupted sleep for about 2–4 days per tooth, starting a few days before the tooth cuts through the gum. Once the tooth emerges, the pain subsides, and sleep usually returns to normal quickly. If sleep problems persist longer, consider other causes such as illness or a sleep regression.
Is it normal for a teething baby to wake up screaming every hour?
Yes, unfortunately that is a common teething symptom. The pressure of a tooth pushing through can cause sharp pains that wake babies during light sleep. Frequent wakings with crying are typical, though very distressing for parents. Comfort measures and pain relief can help reduce the frequency.
Should I give my teething baby pain medicine before bed?
You can give acetaminophen or ibuprofen if your baby is clearly in pain and cannot settle. Ibuprofen is often preferred because it reduces inflammation. Always follow weight-based dosing and check with your pediatrician first, especially for babies under 6 months. Avoid using medicine for more than 2–3 days without consulting a doctor.
Does teething cause fever that makes babies sleepy?
Teething can cause a mild temperature rise (typically under 100.4°F) due to localized inflammation. This low-grade fever can make a baby appear drowsy or sleepy. However, if the fever is higher or accompanied by other symptoms, it may be an infection, not just teething. Always monitor your baby’s behavior and consult a doctor if you’re unsure.
How can I tell the difference between teething sleep changes and a sleep regression?
Teething sleep changes usually come with visible signs like swollen gums, excessive drooling, and chewing on fists or objects. The disruption typically lasts only a few days and coincides with a new tooth. Sleep regressions are age-related (e.g., 4-month, 8-month regression) and may last 2–6 weeks without physical teething symptoms. If you see red, puffy gums and a tooth bud, it’s likely teething.
