I still remember the morning I noticed a tiny white edge poking through my youngest son’s gum. He’d been drooling rivers for weeks and gnawing on everything in sight, from my fingers to the edge of his high chair to his big brother’s toys. That first little tooth felt like such a milestone.
If you’re in the middle of the teething phase or bracing yourself for it, you probably have a lot of the same questions I did. When does each tooth actually come in? Is my baby’s fussiness really from teething, or is something else going on? And what helps when they’re miserable at 2 a.m.? Having gone through this three times now, I can tell you that a clear baby teething timeline won’t stop the drool, but it does make the whole thing feel a lot less chaotic.
When Does Teething Start?
Most babies get their first tooth somewhere between 4 and 7 months, but there’s a wide range of normal. Some babies start as early as 3 months, while others don’t see their first tooth until well past their first birthday. My daughter got hers pretty early, but my youngest son took his sweet time. Both perfectly healthy, just on their own schedules.
Genetics plays a significant role here. If you or your partner were early or late teethers, your baby may follow the same pattern. Premature babies may also teethe a bit later when calculated by their adjusted age. The American Academy of Pediatrics recommends contacting a pediatric dentist if your baby hasn’t gotten any teeth by 18 months, but before that point, a wide range is completely normal.
Something I didn’t know until my first: teeth actually begin developing before birth. By the time your baby is born, all 20 primary teeth are already sitting beneath those tiny gums, just waiting for their turn.
The Complete Baby Teething Timeline
Every baby is different, so treat the ages below as general ranges rather than exact deadlines. Your child’s teeth may come in a little earlier, a little later, or even in a slightly different order. One pattern that does hold up pretty consistently: teeth tend to appear in pairs (left and right around the same time), and lower teeth usually show up just before the upper ones.
6–10 Months: Bottom Front Teeth (Lower Central Incisors)
The two bottom front teeth are almost always the first to appear. You’ll likely notice your baby becoming extra drooly and wanting to chew on everything a few days before you spot that first white edge breaking through the gum. These tiny teeth are thin and sharp, which will come in handy once your baby starts trying solid foods.
8–12 Months: Top Front Teeth (Upper Central Incisors)
Shortly after the bottom pair, the two upper front teeth make their entrance. This is when you start getting those adorable toothy grins in photos. With my youngest, the top two came in pretty quickly after the bottom pair, and I noticed he seemed more bothered by the upper teeth than the lower ones. His gums looked noticeably more swollen up top.
9–16 Months: Lateral Incisors (The Ones Next to the Front Teeth)
The lateral incisors fill in on either side of the front teeth, usually with the upper ones arriving before the lower pair. By the end of this stage, your baby may have up to eight teeth — a full set of front teeth that makes their smile look suddenly very grown-up.
13–19 Months: First Molars
This is the stage that caught me off guard. The first molars are the big, flat teeth toward the back of the mouth, and they skip right past the canines, leaving a temporary gap. Because molars have a larger surface area pushing through the gum, many parents notice that this stage is more uncomfortable than the front teeth. My youngest is going through this right now, and the disrupted naps are real.
Once these come in, your toddler can handle way more foods at the table. Molars do the real grinding work, so meals get a lot easier from here.
16–23 Months: Canines (The Pointy Ones)
The canines fill in that gap between the front teeth and the molars. These pointed teeth are smaller but can still cause some fussiness as they push through. Once they’re in, your toddler can really tear into food, which is both exciting and a little terrifying if you’ve ever watched a toddler attack a piece of chicken.
23–33 Months: Second Molars
The final set of baby teeth to arrive are the second molars, way at the back of the mouth. These are sometimes called the “two-year molars” because they typically show up around your child’s second birthday, though they can take until almost age 3. Once these are in, your child has a full set of 20 primary teeth — 10 on top and 10 on the bottom.
After the second molars come in, you’ll have a break from teething until around age 6, when those baby teeth start falling out and permanent teeth begin to replace them.
Teething Symptoms: Sorting Fact from Fiction
I really wish someone had laid this out for me when my daughter was a baby, because there’s a lot of bad information floating around. Some of it is just annoying, but some can actually be harmful if it leads you to brush off signs of real illness.
Symptoms That Are Actually Linked to Teething
The American Academy of Pediatrics has reviewed quite a bit of research on this, and the list of real teething symptoms is actually shorter than most people think. Swollen or tender gums around the spot where a tooth is coming in, more drooling than usual (sometimes a lot more), wanting to chew or bite on anything within reach, and some fussiness in the days right before a tooth breaks through. That’s basically it.
The good thing is, all of this is mild and usually only lasts a few days around each tooth.
Symptoms That Are NOT Caused by Teething
Now for the stuff that gets blamed on teething but really shouldn’t be.
Fever. This is the biggest teething myth. According to both the AAP and Cleveland Clinic, teething may cause a very slight increase in body temperature — but not a true fever. A true fever is defined as 100.4°F (38°C) or higher. If your baby’s temperature reaches that level, it is almost certainly caused by an illness or infection, not by a tooth coming in. The timing is confusing because teething begins around 4–7 months, which is exactly when babies start losing their passive immunity from birth and becoming more susceptible to viruses.
Diarrhea. Despite the common belief, teething does not change how your baby’s digestive system works. The AAP says there’s no connection. If your baby has diarrhea lasting more than a day, it’s worth calling your pediatrician.
Severe rashes, ear pulling, or excessive crying. While a bit of redness around the mouth from drool is normal, other rashes, persistent ear tugging, or inconsolable crying are not teething symptoms and should be evaluated by your doctor.
How to Help Your Teething Baby
There are a handful of things that genuinely help, and a few popular products you should skip entirely.
What Works
Cold pressure on the gums. A chilled (not frozen) teething ring made of firm rubber works really well. You can also wet a clean washcloth, chill it in the refrigerator, and let your baby gnaw on it. The cold helps reduce swelling and numbs the gums slightly. Avoid frozen teething rings or objects — they can be too hard and actually hurt your baby’s gums.
Gentle gum massage. Wash your hands, then use a clean finger to gently rub and apply light pressure to your baby’s gums where the tooth is coming in. This simple technique is recommended by the AAP, and in my experience, it’s often the quickest way to calm a fussy teether. My youngest immediately relaxes when I do this before his nap.
Something safe to chew. Babies instinctively want to apply pressure to their gums during teething, so give them something appropriate to chew on. Firm rubber teething toys work great. Make sure whatever you offer is large enough that it can’t be a choking hazard and doesn’t have small parts that could break off.
Frozen fruit in a mesh feeder. If your baby is 6 months or older and has started solids, this one is a game-changer. Put some frozen banana, strawberry, or mango in a mesh feeder and let them gnaw away. They get the cold relief on their gums plus a little snack. My youngest goes quiet for a solid ten minutes with one of these, which in teething-land feels like a miracle.
Stay ahead of the drool rash. All that extra saliva can irritate the skin around your baby’s mouth, chin, and neck folds. Gently pat the area dry throughout the day with a soft cloth (don’t rub, it’ll make things worse), and apply a thin layer of petroleum jelly or Aquaphor as a barrier. A drool bib during the day helps too. This won’t fix the teething, but it’ll save your baby from a painful rash on top of sore gums.
Pain relief when needed. If your baby seems particularly uncomfortable and the above methods aren’t enough, talk to your pediatrician about infant-appropriate pain medication such as acetaminophen. Your doctor can advise on safe dosage for your baby’s age and weight. This can be especially helpful at bedtime when teething discomfort peaks.
What to Avoid
Teething necklaces and bracelets. I know amber teething necklaces are everywhere on Instagram, but both the AAP and the FDA recommend against them. The strangulation and choking risks are real, and there’s no scientific evidence that amber (or silicone, or wood) beads relieve teething pain. I know it’s hard to watch your baby be uncomfortable, but a necklace isn’t the answer.
Numbing gels containing benzocaine. The FDA has issued a clear warning that over-the-counter oral products containing benzocaine (sold under brands like Orajel, Anbesol, and others) should not be used on children under 2 years old. These products can cause a rare but life-threatening condition called methemoglobinemia, which severely reduces the amount of oxygen in the blood. Beyond the safety risk, these gels wash out of the baby’s mouth within minutes and provide very little actual relief.
Homeopathic teething tablets. The FDA has also warned against certain homeopathic teething tablets that were found to contain inconsistent amounts of belladonna, a toxic substance. Stick with the simple stuff: cold washcloths, rubber teething rings, and a clean finger on the gums.
Teething and Sleep: Surviving the Rough Nights
I won’t sugarcoat it: teething can disrupt sleep, and the molar stages tend to be the worst. When my youngest started cutting his first molars, we had about a week of more frequent wake-ups and shorter naps. That said, some pediatricians will tell you that teething discomfort is actually too mild to wake a baby, and that what you’re seeing might be a developmental leap or a mild virus happening at the same time. Honestly? It can be hard to tell. Either way, the disruption is temporary. Each tooth typically causes a few rough days, and then things settle.
Whatever your sleep approach is, try to keep it consistent during teething. If something was working before the tooth started coming in, stick with it. It’s tempting to throw in a new strategy when everyone’s exhausted at 3 a.m., but those “just for tonight” changes have a way of becoming the new normal long after the tooth is through. (If you’re looking for more on this, I put together a whole list of baby sleep essentials that helped us.)
What helped us: a gum massage right before laying my son down, and on the toughest nights, a dose of pediatrician-approved pain relief about 30 minutes before bedtime. On the worst nights, I just kept reminding myself this would pass in days, not weeks. It always did.
When to Call the Doctor
Most of the time, teething is just something you ride out. But there are a few situations where it’s worth picking up the phone:
If your baby has a fever of 100.4°F (38°C) or higher. As we covered above, this is not a teething symptom — it indicates illness or infection that needs evaluation.
If no teeth have appeared by 18 months. The AAP recommends seeing a pediatric dentist at this point. While late teething is often just a variation of normal, your dentist can check that everything is developing properly beneath the gums.
If your baby refuses to eat or drink for an extended period. Mild fussiness around meals is normal during teething, but complete refusal of food and especially fluids warrants a call to the doctor.
If symptoms seem too severe. Teething causes mild discomfort — not extreme pain. If your baby is inconsolable, seems very unwell, or has symptoms like persistent diarrhea, high fever, or a rash, something else is going on and needs medical attention.
One more thing: the AAP recommends scheduling your baby’s first dental visit by their first birthday, or within six months of their first tooth, whichever comes first. It’s more of a check-in than anything stressful. And once that first tooth is in, it’s time to start brushing — a soft baby toothbrush with a tiny smear of fluoride toothpaste (about the size of a grain of rice) twice a day. I know it feels silly brushing one tooth, but it sets the habit early and protects against cavities from the start.
The Big Picture
So here’s teething in a nutshell: bottom front teeth show up first around 6 months, the rest fill in gradually over the next two years, and by age 3 your child will have all 20 baby teeth. Real symptoms are limited to sore gums, drool, and some fussiness. Fever, diarrhea, and rashes are not teething. A chilled teething ring, a clean finger on the gums, and frozen fruit in a mesh feeder will get you through most of it.
Right now, my youngest is working on his molars. His cheeks are rosy, there’s a permanent damp spot on his shirt collar, and he’s developed a thing for chewing the corners of his board books. It’s messy, it’s drooly, and it won’t last forever. A year from now I’ll probably miss this stage. (Or at least, I’ll tell myself I do.)
You’ve got this, mama.
