When Do Babies Start Teething? A Parent's Guide

One of the most common questions I hear from new parents is, "When do babies actually start teething?" If you're looking for a simple answer, the teething journey typically begins around 6 months of age.

But here's the thing about babies: they never read the manual. Every little one follows their own unique timeline, so you might spot that first pearly white as early as 3 months or as late as their first birthday. Both ends of that spectrum are completely normal.

The Teething Countdown Begins

Welcome to one of your baby’s first major baby milestones. The arrival of that first tooth is an exciting—and let's be honest, sometimes challenging—rite of passage for both of you. It's helpful to think of it less as a single event and more as a gradual process, a slow build-up where tiny teeth are working their way to the surface over many months.

This whole process doesn't happen overnight. In fact, you'll probably notice the tell-tale signs—like a sudden increase in drool and a new obsession with chewing on everything—weeks or even months before that first tooth actually pokes through the gums. This is your baby’s way of prepping for the main event.

What's a "Normal" Teething Timeline?

While that "average" start time is around the half-year mark, the reality on the ground is far more varied. Teething is one of those developmental steps where the range of what's considered normal is incredibly wide.

Genetics actually play a pretty big role here. If you or your partner were an early or late teether, there’s a good chance your baby will follow a similar pattern.

The first teeth to show up are almost always the bottom two middle teeth (the lower central incisors). After their debut, the top two middle teeth usually follow. Knowing this predictable pattern can help demystify the whole process, giving you a general roadmap for what to expect as more teeth pop up over the next couple of years.

What the Research Shows

Most pediatric experts agree on the 6-month average, but they also stress that the window is wide, stretching from 3 months all the way to 12 months. Studies show that by their first birthday, most babies will have between two and four teeth.

One large research on early life factors in teething really highlighted this variability. It found that while 59.1% of babies had no teeth at 6 months, a surprising 22.7% already had seven or more! It just goes to show how different every child's journey can be. The same study also noted that boys often get their first tooth about a week earlier than girls.

As you navigate this new phase, remember that tracking your baby’s progress is helpful, but comparing them to others isn’t. Each child truly walks their own path.

Key Takeaway: Try not to stress if your baby is an early bird or a late bloomer in the teething game. As long as they're happy and developing well otherwise, their teeth will show up right on their own schedule.

To give you a clearer picture of what to expect, this timeline maps out the average eruption schedule for each set of baby teeth. Think of it as a handy reference to help you anticipate which teeth are coming next and feel a bit more prepared for each new stage.

Baby's First Teeth: An Eruption Timeline

Type of Tooth	Typical Age of Eruption (Top Teeth)	Typical Age of Eruption (Bottom Teeth)
Central Incisors	8-12 months	6-10 months
Lateral Incisors	9-13 months	10-16 months
Canines (Cuspids)	16-22 months	17-23 months
First Molars	13-19 months	14-18 months
Second Molars	25-33 months	23-31 months

Remember, this is just a guide! It's perfectly fine if your baby's teeth come in a slightly different order or on a different timeline. The most important thing is celebrating each new arrival as it happens.

Decoding the Signs of Teething

Has your normally happy-go-lucky baby suddenly transformed into a drooling, irritable, sleep-averse little mystery? Welcome to the great teething detective game. Long before you spot that first pearly white, your baby will start sending out some not-so-subtle clues that something is happening just below their gums. Learning to read these signs is your new superpower—it helps you understand what’s going on and how to make them more comfortable.

The most famous—and messiest—sign is the drool. Seriously, you'll wonder how such a tiny person can produce a Niagara-sized waterfall of saliva, but it’s a classic teething symptom. All that extra moisture can sometimes lead to a mild rash on their chin, cheeks, or neck. Keeping the area as clean and dry as possible will help prevent irritation. For more on this, our guide on baby skin care tips has some gentle solutions to keep that delicate skin happy.

The Most Common Teething Symptoms

Beyond the drool, a whole host of symptoms can point to an incoming tooth. It's rare for a baby to have all of them at once, but you’ll probably recognize a few from this list.

• Intense Chewing and Gnawing: Suddenly, everything is a chew toy—your fingers, the remote, their own fists. This isn't just random; the pressure they apply by chewing actually helps relieve the counter-pressure they feel from that tooth pushing its way up.
• Swollen and Tender Gums: If you can get a quick peek inside their mouth, you might notice their gums look a little puffy or red right where a tooth is about to pop through. Sometimes, you can even see a tiny white nub just under the surface.
• Irritability and Fussiness: This one’s a classic. That constant, dull ache in their gums can make even the most cheerful baby grumpy. The discomfort isn't always constant; it often comes and goes, leading to those confusing, out-of-nowhere fussy spells.
• Disrupted Sleep: Just when you thought you finally had a sleep routine figured out, teething arrives to shake things up. The discomfort can feel more intense at night when there are fewer distractions, leading to more frequent wake-ups.
• Changes in Eating Habits: You might see a shift here. Some babies may refuse to eat or drink because the sucking motion can increase the pressure on their sore gums. On the other hand, some babies want to nurse or bottle-feed more because they find the act itself soothing.

While teething is something every baby goes through, how they handle it varies wildly. Some babies might just be a little extra fussy for a couple of days and then—poof!—a tooth appears. Research shows this is pretty common; a comprehensive study found that about 70% of parents reported symptoms like dribbling, red gums, and general fussiness.

Debunking Common Teething Myths

Knowing what to look for is only half the battle. It's just as important to know what not to blame on teething. Over the years, several myths have made the rounds that can cause a lot of unnecessary worry or, even worse, lead parents to overlook a real illness. Let's clear the air.

Parenting Pro-Tip: Teething causes discomfort, not illness. Think of it as a persistent, annoying ache. If your baby seems genuinely sick, it's almost always something else.

Myth 1: Teething Causes High Fevers This is the most critical myth to bust. While some pediatricians believe the inflammation from teething can cause a very slight rise in temperature, it does not cause a true fever, which is defined as 100.4°F (38°C) or higher. A real fever is a clear signal that your baby's body is fighting an infection, and it has nothing to do with a tooth coming in.

Myth 2: Teething Causes Diarrhea There's no scientific evidence that links teething directly to diarrhea. A much more likely explanation is that teething babies put everything they can get their hands on into their mouths—including germy fingers and toys. This dramatically increases their exposure to viruses and bacteria that can cause an upset stomach.

Myth 3: Teething Causes Runny Noses and Coughs Just like with fever and diarrhea, these are classic cold or allergy symptoms, not teething signs. It's easy to want to lump everything together, but don't dismiss these as "just a tooth."

If your baby has a high fever, diarrhea, a persistent cough, or seems unusually lethargic or unwell, don't chalk it up to teething. Those symptoms warrant a call to your pediatrician to make sure you’re not missing an underlying illness that needs attention. Knowing the difference empowers you to get your little one the right care, right when they need it.

Your Teething Toolkit: Safe Ways to Soothe Sore Gums

So you've figured it out—teething is the culprit behind your baby's grumpiness. The next step is finding some real relief for those sore little gums. Think of this as building your teething "toolkit," a collection of safe, effective strategies to comfort your baby without introducing any risks.

We’ll start with the simple stuff you can try right at home. These are your first line of defense and often work like a charm.

Gentle, At-Home Remedies

Before you even think about medicine, many parents find that a bit of pressure or a cool sensation is all it takes. These methods are fantastic because they use the body's own responses to cold and pressure to naturally numb the pain and offer immediate comfort.

Here are a few tried-and-true tricks that work wonders:

• A Gentle Gum Massage: Sometimes the simplest things are the most effective. With clean hands, just use one finger to gently but firmly rub your baby's gums. That little bit of counter-pressure can feel incredibly good when a tooth is trying to push its way through.
• Chilled (Not Frozen!) Teethers: A cold teether is a classic for a reason. Stick a solid silicone or rubber teething toy in the refrigerator for a while. The coolness helps bring down the swelling and numbs the sore spots.
• A Cold Washcloth: Don't have a teether on hand? No problem. A clean, damp washcloth, chilled in the fridge, works just as well. Your baby can gnaw on it safely, and the nubby texture of the cloth gives their gums a satisfying massage.
• Firm Edible Teethers: If your little one has started solid foods, offering something firm and cold to gnaw on can be a game-changer. Think of a thick, peeled carrot stick (supervised, of course!) or a teething biscuit designed to dissolve slowly.

When to Consider Medication

While home remedies are fantastic, some teething episodes are just plain rough, especially when those big molars are making their debut. For those tougher days, an over-the-counter pain reliever can be a safe option, but only with your pediatrician’s green light.

Expert Tip: Always, always call your pediatrician before giving your baby any medication. They will give you the exact dose based on your baby’s current age and weight, which is absolutely critical for their safety.

Your doctor will likely recommend either ibuprofen (like Advil or Motrin) or acetaminophen (Tylenol). Ibuprofen is typically okay for babies 6 months and older, while acetaminophen can sometimes be used a bit earlier. Your pediatrician will know which is right for your baby.

Safety First: What to Avoid

Knowing what not to do is just as important as knowing what helps. The internet is full of "remedies" that are not just ineffective but downright dangerous. Your baby's safety comes first, so please steer clear of these.

Here’s a non-negotiable list of things to avoid:

• Amber Teething Necklaces: The American Academy of Pediatrics has issued strong warnings against these. They are a serious strangulation and choking hazard, and there's zero scientific evidence they actually do anything for pain.
• Topical Numbing Gels: Stay away from any teething gels or creams that contain benzocaine or lidocaine. The FDA has warned that benzocaine can cause a rare but life-threatening condition called methemoglobinemia, which cuts down the oxygen in the blood.
• Homeopathic Remedies: Be very wary of homeopathic teething tablets and gels. The FDA has found that many contain inconsistent and sometimes dangerous levels of belladonna (a toxic substance) that can be incredibly harmful to a baby.
• Frozen Teethers: Chilled is good, but frozen is not. A rock-solid frozen teether can be too hard on your baby’s delicate gums and could even cause bruising or freezer burn. The refrigerator is all you need for safe cooling.

By sticking with proven, safe methods and avoiding these risky fads, you can help your little one get through the teething rollercoaster safely and with a lot more comfort.

Mapping Your Baby's Teething Journey

As any seasoned parent will tell you, teething isn’t a one-and-done event. It’s more of a two-year-long series of dental debuts, and understanding the general timeline can make the marathon feel much more manageable.

Think of it like a play in three acts. Act one brings those first tiny, sharp incisors, while the grand finale features the big second molars way in the back. Each stage has its own unique challenges, but knowing what’s coming next can bring a welcome sense of order to an often chaotic time.

The Front Teeth Arrival

The first teeth to show up are almost always the lower central incisors—the two right in the bottom-front. You can usually expect them between 6 and 10 months. Not long after, their partners on top, the upper central incisors, pop through between 8 and 12 months.

This first phase is often more exciting than anything else. Your baby will definitely be drooly and might be a little cranky, but these front teeth are thin. They tend to slice through the gums with less drama than the bigger, bulkier teeth that come later.

Next on the scene are the lateral incisors, which sit right next to the middle ones. The upper laterals typically appear between 9 and 13 months, followed by the lower pair between 10 and 16 months. Just like that, your baby has a charming, eight-toothed grin.

This handy timeline shows you which soothing methods work best at each stage. As you can see, you can start with the simple stuff like gum massage and move on to other remedies as your baby gets older and the discomfort ramps up.

The Molar March and Canine Crunch

Just when you feel like you've got this teething thing figured out, the game changes. The molars and canines are next, and they tend to make a much bigger entrance.

First up are the first molars. These are the wide, flat teeth used for grinding, and their large surface area means they can be particularly uncomfortable coming through. The top pair usually arrives between 13-19 months, with the bottom pair showing up between 14-18 months.

A Little Advice From Experience: The "Molar March," as I like to call it, is often the toughest part of teething. The tricks that worked for the tiny incisors might not cut it anymore. This is a great time to double down on gum massage and talk to your pediatrician about pain relief if your little one is really struggling.

After the first molars, the pointy canines make their appearance (some parents affectionately call them "fang teeth"). Their sharp shape can make for another tricky eruption. Look for the upper canines between 16-22 months and the lower ones between 17-23 months.

As these new teeth pop up, it’s a perfect time to start thinking about long-term dental health. Finding a good family practice early on helps build a positive foundation for the journey with your family dentist from toddlerhood to adulthood.

The Grand Finale: Second Molars

The final act in this dental drama is the arrival of the second molars. These are the largest of all the baby teeth, located at the very back of your child's mouth. Because they're so big, their arrival can feel like a repeat of the first molar experience.

Expect the lower second molars to come in between 23-31 months, while the upper pair finally completes the set between 25-33 months. By the time your child is around 2.5 to 3 years old, they’ll likely have their full set of 20 primary teeth. Hooray!

The whole process is surprisingly predictable. It starts at the front and moves toward the back: incisors, first molars, canines, and then second molars. Knowing this general order helps you anticipate the fussier periods and feel a little more in control. Once that final molar is in place, you can officially hang up your teething toolkit. You've made it.

Caring For Those New Pearly Whites

That first little tooth peeking through the gums isn't just a milestone for the baby book—it's the official starting line for a lifetime of dental health. Taking care of these new pearly whites is simpler than you might think, and building good habits now paves the way for a healthy smile for years to come.

You can actually start even before any teeth show up. Gently wiping your baby's gums with a clean, damp washcloth or a soft gauze square after they eat helps clear away lingering bacteria. Plus, it gets them comfortable with you cleaning their mouth—a big win for later!

Starting the Brushing Routine

The second you spot that first tooth, it’s time to bring in a toothbrush. Don't wait for a full row to appear; that single little tooth needs attention right away.

Your toolkit is simple. You’ll need an infant-sized toothbrush with the softest bristles you can find. These are made specifically for tender baby gums and tiny teeth. Some parents prefer the little silicone finger brushes, which can feel less intrusive and give you more control in a very small mouth.

And what about toothpaste? The American Academy of Pediatrics (AAP) recommends using a fluoride toothpaste from the very beginning, but the amount is key.

For children under 3 years old, all you need is a tiny smear of toothpaste about the size of a grain of rice. This minuscule amount provides crucial fluoride protection and is perfectly safe if (and when) they swallow it.

Aim to brush twice a day—a quick brush after their first feeding of the day and another right before they go down for the night. Keep it light and fun! Sing a song, make silly faces, or let them hold a brush (while you do the real work) to make it a positive, normal part of their day.

Scheduling That First Dental Visit

This one catches a lot of parents by surprise, but the rule of thumb is to book your baby's first dental visit right after their first tooth appears, and no later than their first birthday. Think of it as preventative care, not just a reaction to a problem.

This early "well-baby check for the mouth" is incredibly valuable for a few reasons:

• It establishes a "dental home." Your child starts to build a positive, non-scary relationship with the dentist's office right from the start.
• The dentist can spot issues early. They’ll check for proper development and any early warning signs of tooth decay.
• You get expert, personalized advice. This is your chance to ask a pro all your questions about brushing, diet, pacifier use, and more.

Starting a relationship with a dentist early on is a huge step. Taking the time for finding a trusted children's dentist now sets the stage for their future oral health. This first visit is usually very low-key—your baby will likely just sit on your lap for a quick peek—but it lays a foundation for a lifetime of healthy teeth.

Wrapping Up: You've Got This!

Navigating the teething phase can feel like a rollercoaster of drool, fussiness, and sleepless nights. But remember, this is a normal—and temporary—part of your baby's development. Every new tooth is a tiny victory, bringing your little one one step closer to a full, healthy smile. Trust your instincts, lean on your toolkit of safe remedies, and don't hesitate to call your pediatrician when you're unsure. You're doing a fantastic job, and you'll both get through this one pearly white at a time.
