Teething does not make babies sleep more; in fact, it often disrupts sleep, leading to more frequent night wakings and shorter naps. While some babies may seem sleepier due to low-grade fever or discomfort, the most common pattern is increased fussiness and less sleep. Understanding the real signs of teething—and how to soothe your baby—can help you avoid unnecessary worry and get everyone the rest they need.
You’re not alone if you’ve ever wondered, do baby sleep more when teething? It’s a question that pops up on every parenting forum and late-night Google search. Maybe your baby has been extra drowsy lately, or perhaps they’re waking up more often. The topic can be confusing because teething affects every child differently.
The short answer might surprise you: most babies sleep less, not more, during teething. But there’s a twist. Some parents report their baby sleeping more, and that can happen for a few reasons. Let’s unpack the real science behind teething and sleep, separate fact from fiction, and give you practical tips to help your baby (and you) get through this phase.
Teething usually starts around 4 to 7 months and continues until age 2 or 3. During this time, you’ll likely notice changes in sleep, appetite, and mood. But before you assume every sleep disruption is due to teeth, let’s look at what the research actually says about the question: do baby sleep more when teething?
Key Takeaways
- Teething rarely increases total sleep time: Most studies show that teething is linked to more nighttime wakings, not longer sleep.
- Common sleep disruptors: Gum pain, drooling, and mild inflammation can make it harder for babies to fall and stay asleep.
- Some babies may appear sleepier: This is usually due to a low-grade fever or overall fussiness that exhausts them, not a direct effect of teething.
- Look for other teething signs: Beyond sleep changes, watch for swollen gums, increased chewing, drooling, and a slight rise in temperature (but not high fever).
- Teething does not cause serious illness: High fever, diarrhea, or significant sleep regression is usually from something else, like an infection.
- Soothing techniques can help: Cold teething rings, gentle gum massage, and pain-relief teethers can ease discomfort and improve sleep quality.
- Stick to a consistent bedtime routine: Predictability helps babies cope with teething pain and reduces sleep disruptions.

What Does Science Say About Teething and Sleep?
Research studies on teething symptoms
A landmark study published in Pediatrics followed a group of infants during their first year and recorded daily symptoms. The researchers found that teething was linked to increased fussiness, drooling, and gum rubbing. However, sleep patterns showed a clear trend: babies woke up more often, not less. The study noted a slight rise in body temperature (less than 101°F) but no significant increase in total sleep duration.
Why some parents swear their baby sleeps more
You might hear a friend say, “My baby slept 14 hours when her first tooth came in!” This does happen, but it’s likely due to a low-grade fever or minor discomfort that makes the baby lethargic. When a baby feels slightly under the weather, they may become sleepier as their body focuses on healing. But this is not the typical response. Do baby sleep more when teething? Usually, no. In fact, studies looking at actigraphy (sleep trackers) show that teething nights have more wake episodes.
The role of inflammation and pain
When a tooth erupts through the gums, it causes local inflammation. This releases chemicals that can make the gums sore and tender. For adults, pain typically disrupts sleep. Babies are no different. The discomfort makes it harder for them to fall asleep and stay asleep. So if your baby is sleeping more, it’s not directly from teething—it may be a coincidence or a sign of something else, like a mild illness.
Common Sleep Changes During Teething (And What They Really Mean)
More night wakings
The most common report is increased waking. Your baby might wake up crying, wanting to nurse or be rocked. This is a classic sign that teething is causing discomfort. The pain often worsens at night because there are fewer distractions. Also, when babies lie down, blood flow to the head increases, which can heighten gum sensitivity.
Shorter naps
During the day, teething babies may take shorter naps. They might fall asleep easily from exhaustion but wake up after 20 minutes because the pain returns. Do baby sleep more when teething during the day? Rarely. Most parents notice fragmented sleep.
Changes in sleep position
Some babies start sleeping with their heads tilted or refuse to lie flat. They seek comfort by pressing their gums against something, like a mattress or your shoulder. This doesn’t necessarily mean they’re sleeping more—just that their sleep positions change due to discomfort.
Fussiness at bedtime
It’s common for teething babies to resist bedtime. They may cry when you put them down or demand extra cuddles. This increased bedtime fussiness is a strong clue that a tooth is coming. Keep your routine calm and offer extra soothing without loading up on unnecessary medicines.
Why Some Babies Seem Sleepier When Teething
Low-grade fever and sleepiness
Teething can raise a baby’s body temperature slightly, but not to the level of a fever (above 100.4°F). A mild elevation can make a baby feel tired and lethargic. If your baby has a temperature below 101°F and is sleeping more, it could be a teething reaction. But if the temperature goes higher, it’s likely a separate illness.
Compensatory sleep after a restless night
Imagine your baby has a tough night with frequent wakings. The next day, they might be extra tired and take longer naps, sleeping more overall. This catch-up sleep can make it appear as if teething increases sleep, but it’s actually the aftermath of a disrupted night. Pay attention to the full 24-hour pattern.
Coincidental sleep milestones
Teething often happens at the same time as other developmental leaps. Around 4-6 months, babies go through a major sleep regression. They also start rolling over, teething, and becoming more aware. Sometimes what we blame on teeth is actually a normal sleep progression. So do baby sleep more when teething? It’s often a mix of teething and other growth factors.
How to Tell If Your Baby’s Sleep Change Is Really From Teething
Look for the classic signs
Besides sleep issues, check for these teething symptoms:
- Swollen, red gums – You may see a bump or a whitish spot where the tooth is coming.
- Increased drooling – More than usual, often leading to a rash on the chin or neck.
- Chewing on everything – Fingers, toys, your shoulder—anything to massage the gums.
- Irritability – Especially when you touch their mouth or during meals.
- Mild temperature – Usually below 101°F.
Consider timing and duration
Teething symptoms typically start 3-5 days before a tooth appears and resolve once it breaks through. If sleep issues last longer than a week without a new tooth, another cause is likely. Do baby sleep more when teething for a long period? No, because the acute phase is short. Persistent sleepiness warrants a call to your pediatrician.
Rule out other issues
Separation anxiety, illness, growth spurts, and sleep regressions can all look like teething. If your baby has a runny nose, cough, or diarrhea, it’s probably not just teeth. Teething does not cause high fever, vomiting, or severe diarrhea. Always check with your doctor if you’re worried.
Practical Tips to Help Your Baby Sleep Better During Teething
Soothing techniques for daytime
During the day, offer cold teething rings (chilled, not frozen, to avoid frostbite). You can also massage your baby’s gums with a clean finger or a soft silicone teether. Keeping the gums cool reduces inflammation and can make nighttime easier. Let your baby chew on a wet washcloth that’s been in the fridge.
Bedtime routine adjustments
Stick to a consistent routine—bath, book, lullaby, bed. Add an extra step like a gentle gum massage using a clean finger. A predictable routine signals that it’s time to rest, even if their mouth hurts. Avoid introducing new sleep props during teething; you don’t want to create long-term habits.
Pain relief options
If your baby is very uncomfortable, you can use age-appropriate pain relievers like acetaminophen or ibuprofen (for babies 6 months and older). Always follow dosing instructions. Never use numbing gels containing benzocaine or lidocaine—they can cause serious side effects in infants. Consult your pediatrician before giving any medication.
Overnight strategies
If your baby wakes crying, try comforting them without picking them up right away. Pat their back, sing softly, or offer a pacifier (cooled if you have a teether pacifier). If they need to nurse or have a bottle, keep it quick and calm. Try to avoid feeding to sleep every time, as that can lead to sleep associations. Remember, teething phases pass quickly—usually in a few days.
Conclusion
So, do baby sleep more when teething? The truth is, most babies sleep worse, not better. The discomfort of emerging teeth disrupts their rest, leading to more night wakings, shorter naps, and fussy bedtimes. A small number of babies may sleep more due to mild fever or exhaustion, but this is not the norm.
Understanding what’s really happening helps you respond with patience and effective solutions. Instead of worrying, you can focus on soothing your baby’s gums, maintaining a consistent routine, and watching for other teething signs. And if your baby’s sleep changes are severe or last too long, trust your instincts and talk to your doctor.
Teething is a short season in your baby’s first years. With the right knowledge and a little extra cuddling, you’ll both get through it—and sleep soundly again soon.
Frequently Asked Questions
Can teething cause a baby to sleep for 12 hours straight?
It’s possible but very uncommon. Some babies do sleep longer when they have a low-grade fever from teething, but most will wake up more often. If your baby is sleeping excessively and is hard to wake, contact your pediatrician.
Do babies sleep more with molars or front teeth?
Molars are often more painful because they are larger and have multiple points. This can lead to more sleep disruption, not more sleep. Front teeth usually cause milder symptoms. Every baby reacts differently, but pain typically reduces sleep quality.
How long does teething sleep disruption last?
Most sleep disturbances last 3 to 5 days before a tooth emerges. Some babies may have off-and-on symptoms for a week. If sleep problems persist for more than two weeks, look for other causes like illness or a sleep regression.
Should I wake my teething baby to feed at night?
If your baby is sleeping well despite teething, there’s no need to wake them for feeding unless your pediatrician advises it for weight gain. Teething babies often have reduced appetite during the day, so they might need extra calories at night, but follow your baby’s cues.
Do babies sleep more when teething and have a fever?
Only if the fever is very low (<100.4°F). A higher fever usually means an infection, not teething. Teething does not cause high fevers. If your baby has a fever above 101°F and is sleeping more, consult your doctor immediately.
Is it normal for my baby to sleep 2 hours less during teething?
Yes, a reduction of 1-2 hours of total sleep in a 24-hour period is common during teething. This is due to increased discomfort and night wakings. The sleep usually returns to normal once the tooth breaks through.
