Does Teething Cause Constipation?

Short version: Teething itself doesn’t directly “cause” constipationbut it can absolutely seem like it does. Teething often shows up right when babies are changing how they eat, drink, and sleep… and all of those things can change how they poop. In other words: teething is usually the coincidence, not the culprit.

Let’s unpack what’s actually happening (and how to help your baby get back to their regularly scheduled diaper programming) without turning your home into a tiny gastrointestinal think tank.

The Poop-Truth: Teething vs. Constipation

Teething is when those first baby teeth start pushing through the gums. Constipation is when poop becomes hard, dry, painful, or difficult to pass. Parents often connect the two because the timing overlaps: many babies start teething around the same months they’re also:

• starting solid foods,
• drinking differently (less milk, more sips of water),
• dealing with disrupted sleep and routines,
• and sometimes fighting off their first daycare germs.

So while teething doesn’t directly slow the bowels like a traffic jam on the digestive highway, the side effects of teething (especially changes in appetite and hydration) can make constipation more likely.

What Teething Normally Looks Like (So You Don’t Blame Every Symptom on Teeth)

Teething gets accused of a lot. Some of it’s fair. Some of it is teething getting framed for crimes it didn’t commit.

Common, normal teething symptoms

• Drooling (so much drooling)
• Chewing on everything, including things you did not know were chewable
• Gum swelling/tenderness
• Irritability or crankiness
• Sleep disruption
• Slightly reduced appetite for a day or two

Symptoms that usually mean “something else is going on”

High fever, vomiting, significant diarrhea, or a baby who seems truly unwell is not “just teething” territory. If your baby is sick, don’t let teething be the convenient excuse that delays care. (Teeth are needy, but they’re not that powerful.)

So Why Is Your Baby Constipated During Teething?

If you’re staring at a diaper that’s been suspiciously poop-free, these are the usual suspects.

1) Eating less = less “material” to move through

Some babies eat less when their gums hurt. Less milk or fewer solids means less volume going in… which can mean fewer bowel movements. That’s not always true constipationbut it can look like it.

2) Drinking less = harder stools

This is one of the biggest indirect links between teething and constipation. If sore gums make your baby less interested in nursing, bottle-feeding, or sipping water (for older babies), stools can get drier and tougher to pass.

Even a mild dip in hydration can make a noticeable difference, especially if your baby already tends to have firm stools.

3) The “starting solids” overlap

Here’s the classic trap: babies often begin teething around the same time many families introduce solid foods. Early solids can be amazingbut they can also be constipating, especially if your baby’s menu is heavy on:

• rice cereal,
• bananas,
• white bread/crackers,
• cheese and other low-fiber foods.

If solids are increasing while milk intake drops a bit, constipation can appear “suddenly,” and teething gets blamed because it’s the loudest thing happening.

4) Routine disruption (sleep changes, travel, daycare)

Teething can mess with sleep, and poor sleep can mess with… everything. Add travel, schedule changes, or starting childcare, and it’s not unusual for a baby’s pooping rhythm to get weird for a while.

5) Illness and mild dehydration

Sometimes babies happen to catch a cold right when teeth are coming in. If appetite drops, fluid intake dips, or they’re breathing through their mouth more, stool can firm up. If your baby also has fever, vomiting, or seems lethargic, think “illness” first, not teething.

Constipation or Just a “Different Poop Week”?

Babies are not robots, and their poop schedules are not subscription services. Some variability is normal. Constipation is more about stool consistency and discomfort than about counting days.

Signs your baby may be constipated

• Hard, dry stools (pellets or firm logs)
• Straining with little output
• Crying or obvious discomfort while pooping
• Blood streaks on stool (often from tiny anal fissures caused by hard stools)
• Decreased appetite or a tight, uncomfortable belly

Important note: Straining alone doesn’t always mean constipation. Some babies grunt and turn red because they’re learning how to coordinate “push” and “relax.” If the stool is soft, it may be more about learning the process than being truly constipated.

How to Help a Constipated Baby (The Safe, Pediatrician-Friendly Edition)

If you suspect constipation during teething, the goal is to gently soften stools and encourage regular movementwithout turning your kitchen into a chemistry lab.

1) Focus on fluids first

If your baby is nursing or bottle-feeding, encourage more frequent feeds. For older babies who are already cleared for water, offer small sips with meals. Hydration is the simplest constipation helper and often the most effective.

2) Adjust solids: add “P” foods and fiber

If your baby is eating solids, many pediatric resources recommend fiber-rich fruits and vegetables. Parents often remember the “P” foods because they tend to help things move:

• Prunes
• Pears
• Peaches
• Plums

Other options that can be helpful: peas, beans (as appropriate for age), apricots, and whole-grain baby cereals (instead of rice cereal if rice seems to bind your baby up).

3) Consider small amounts of fruit juice (with age-appropriate guidance)

Some pediatric guidance supports using a small amount of apple, pear, or prune juice for babies who are old enough, because these can contain sorbitol, which can help soften stool. The key phrase is small amount. Juice isn’t a daily lifestyle choice for babies; it’s more like a short-term guest star when constipation shows up.

If you’re unsure what’s appropriate for your baby’s age and feeding situation, your pediatrician can give specific dosing guidance.

4) Gentle movement and belly comfort

• Bicycle legs: move your baby’s legs as if pedaling
• Tummy massage: gentle circles on the belly
• Warm bath: relaxes muscles and can make pooping easier

These are safe, low-risk options and can be surprisingly effectiveespecially when constipation is mild and related to a temporary change in eating or drinking.

5) Suppositories, laxatives, and enemas: don’t freestyle

It’s very tempting to jump to “the strong stuff” when you just want your baby to poop and move on with your life. But suppositories, laxatives, or enemas for infants should only be used under medical guidance. If constipation is persistent, severe, or painful, call your pediatrician for a plan.

Teething Relief That Won’t Accidentally Make Things Worse

If teething is reducing your baby’s appetite or fluid intake, helping with gum pain may indirectly help constipation toobecause a more comfortable baby tends to feed better.

Safer teething comfort ideas

• Chilled (not frozen) teething rings
• A clean, cool, damp washcloth to chew on
• Gentle gum massage with a clean finger
• Age-appropriate pain relievers (only if needed, and used as directed by your pediatrician)

What to avoid

Health authorities have warned against using certain medicated teething gels and numbing agents for infants and young children, particularly products containing benzocaine or lidocaine, because of safety risks. Also use caution with unregulated “homeopathic” teething products. If you’re unsure, ask your pediatrician before using any teething medicine.

When to Call the Pediatrician

Most constipation during teething is mild and temporary. But call your child’s healthcare provider if you notice any of the following:

• Constipation that doesn’t improve with simple diet/fluid changes
• Blood in the stool (more than a tiny streak) or ongoing bleeding
• Vomiting, fever, or signs your baby is ill
• Severe belly swelling or intense pain
• Refusing feeds or fewer wet diapers
• Weight loss, poor growth, or repeated constipation episodes

If your baby is very young (especially under a few months) and constipation appears suddenly or seems severe, it’s always worth a call. Very young infants have different “normal” ranges, and it’s better to get individualized guidance.

FAQ: Teething and Constipation (The Questions Everyone Googles at 2 a.m.)

Can teething cause constipation?

Not directly. But teething can lead to less eating and drinking, and that can contribute to harder stools.

Why does constipation show up right when a tooth is coming in?

Timing. Teething often overlaps with starting solids, routine changes, and minor illnesses. The tooth gets blamed because it’s the obvious milestone happening at the same time.

Can teething cause diarrhea instead?

Some babies have slightly looser stools during teething, possibly from swallowing more saliva. But significant diarrhea should be treated as a possible illness, not “just teething.”

My baby is strainingdoes that mean constipation?

Not always. If stool is soft, straining may be normal coordination learning. If stool is hard and your baby seems in pain, constipation is more likely.

Bottom Line

Teething doesn’t directly cause constipation, but it can set the stage for constipation by disrupting feeding, hydration, and routinesespecially during the same months babies often start solids. If your teething baby is constipated, focus on fluids, fiber-friendly foods, gentle movement, and safe comfort strategies for sore gums. And if anything feels “off,” persistent, or severe, call your pediatricianbecause babies don’t come with user manuals, and you shouldn’t have to guess alone.

Real-World Experiences: Teething + Constipation Stories (About of “Yep, Been There”)

Parents don’t usually remember the exact day their baby learned to roll overbut many can recall, with unsettling clarity, the week a tooth arrived and poop disappeared like it joined a witness protection program. Here are a few common “experience patterns” families describe when teething and constipation happen around the same time.

Experience #1: “The Snack Strike”

A baby who normally feeds like it’s their job suddenly acts offended by the bottle or nursing session. They latch, unlatch, glare, and dramatically chew on their own fist instead. A day later, the diaper output slows down. Not because the baby’s digestion brokebecause the input dropped. Once the gum discomfort settles (or once you find a teething routine that helps), feeding improves and the poop schedule quietly returns, as if nothing happened.

Experience #2: “Hello Solids, Goodbye Regularity”

This one is almost unfair. Your baby is around the age where solids are ramping up. You offer rice cereal because it feels “safe,” bananas because they’re easy, and a few crackers because your baby is chewing everything anyway. At the same time, a tooth starts pushing through, and your baby becomes a tiny, adorable chaos goblin. Thenboomhard stools appear. Parents often report that swapping in more fiber-rich purees (think pears, prunes, peaches) and easing back on binding foods helps within a couple of days.

Experience #3: “The Drool Era”

Some babies turn into professional drool factories during teething. Parents might expect drool to loosen everything up (and sometimes it can), but drool doesn’t always equal hydration. Many parents notice their baby still drinks a little less while teething, especially if gums are sore. The baby looks wet on the outside but can be a bit drier on the insideleading to firmer stools. Offering more frequent feeds and watching wet diapers can help you catch that subtle hydration dip.

Experience #4: “The Overnight Mystery”

Teething can disrupt sleep. When sleep gets messy, days get messy, and routines (including poop routines) get messy too. Parents often describe a cycle: baby sleeps poorly → baby feeds oddly → baby poops oddly. In these cases, the constipation is less about the tooth itself and more about the ripple effects of discomfort. Families who find a consistent soothing routinecool washcloths, chilled teething rings, gum massage, and (when appropriate) pediatrician-approved pain reliefoften report that the whole system calms down, including digestion.

Experience #5: “The One That Needed a Call”

Sometimes constipation during teething isn’t mild. Some parents describe stools so hard the baby cries, or they notice a small streak of blood from straining. Others see belly bloating or ongoing refusal to feed. In these situations, families are usually glad they called the pediatriciannot because something scary was always happening, but because getting an age-appropriate plan (and knowing what not to try) brought relief quickly and safely.

If there’s one universal takeaway from real-life teething-plus-constipation stories, it’s this: teething is often the timing, not the cause. When you support comfort, hydration, and fiber, most babies get back to normaluntil the next tooth decides to audition for the role of “Most Dramatic Milestone.”
