Dear Marcus from six months ago: Put down the tactical flashlight. She is not going to let you look in her mouth, and shining a 1000-lumen beam at a five-month-old's face at 2 AM is exactly why your wife is currently threatening to change the WiFi password so you can't access WebMD anymore. You're frantically searching "when do babies get teeth" because your daughter has been drooling like a faulty faucet for three days, but I'm writing from the future to tell you that the first tooth doesn't actually render for another two months.

I know you approach everything like a software deployment, assuming there's a logical sequence of events and a predictable release schedule. You track the exact milliliter output of her bottles and log her sleep in a spreadsheet. But parenthood is an open-source project with terrible documentation, and the dental hardware installation phase is the buggiest part of the entire system. Here's everything I wish I knew before I spent a quarter of my waking life inspecting the inside of a tiny, furious person's mouth.

The timeline is a complete fabrication

If you look up any official developmental charts, they'll tell you that the average baby cuts their first tooth between six and twelve months. As an engineer, I assumed this meant we would see a little white nub exactly on her six-month half-birthday. What the charts don't emphasize enough is the variance, which is absolutely unhinged.

Apparently, it's entirely within normal operational parameters for a baby to get a tooth at three months, or to just remain completely gummy until they're fifteen months old. How are you supposed to plan for a milestone that has a twelve-month delivery window? It's like your contractor telling you the kitchen renovation will be finished sometime between Tuesday and the next presidential election. I was so sleep-deprived one night I was typing "when do babie get teeth" and "why is my babi drooling" into Reddit, hoping some anonymous user could give me a precise date, but it's completely random. My doctor, Dr. Aris, actually chuckled when I brought in my printed Gantt chart of expected tooth eruptions and gently explained that the AAP recommends a dentist visit if there are no teeth by eighteen months, but until then, we just have to wait. Apparently the bottom middle ones usually ship first, but honestly, who even knows anymore.

False positives and system errors

The hardest part of this entire phase isn't the actual tooth breaking through the gums, it's the months of false alarms leading up to it. For about eight weeks, every single time she cried, woke up early, or refused a nap, I confidently declared to my wife that she was teething.

I tracked her temperature religiously. One Tuesday afternoon in November, her temperature hit 100.1°F. I immediately blamed the impending incisors, only for Dr. Aris to explain to me that a true fever—which doctors apparently define as 100.4°F or higher—is not caused by teething. The idea that teething causes high fevers or massive digestive blowouts is just a widespread myth, which meant my daughter actually just had a standard-issue daycare virus from chewing on a communal block. The actual signs of teething are mostly localized to the mouth area: a sudden, dramatic increase in drool that will require you to buy stock in bibs, a mild baseline irritability that makes you question your parenting skills, and swollen red gums.

And speaking of gums, let me warn you about something called an eruption hematoma. It sounds like a sci-fi weapon, but it’s apparently just a bruised, blue-ish bubble that can form over a tooth that’s trying to punch its way out. I saw one, panicked, took seven blurry macro photos with my phone, and uploaded them to the clinic portal, only to be told it's usually harmless and just needs to be monitored by a pediatric dentist.

Hardware solutions for mouth pain

Once the tooth is really imminent, the baby will try to chew on literally everything to create counter-pressure. Your knuckles, your laptop charger, the dog’s tail, the expensive coffee table. You have to redirect them to safe, non-toxic hardware.

We tried a lot of things, and I've very strong opinions about them now. My absolute holy grail is the Avocado Baby Teether. I don't know what kind of acoustic resonance or tactile magic the designers put into the bumpy little "seed" in the middle of this silicone avocado, but it's the only thing that would stop my daughter from screaming during the worst of the upper incisor deployment. It’s 100% food-grade silicone, which satisfies my paranoid need for safety, and the outer rim has a different texture than the middle. I currently have three of these scattered around the house like emergency fire extinguishers.

We also have the Cow Silicone Teether. It’s fine. It works. The silicone is safe and easy to wash, but the ring is a little bit thick, and when she was on the younger side of the teething timeline, she had trouble manipulating it into the exact back corner of her mouth where she wanted it. She still uses it, but the avocado reigns supreme.

My wife's favorite is the Handmade Wood & Silicone Teether Ring. From a purely functional standpoint, I honestly appreciate this one because pure silicone teethers have a nasty habit of becoming lint rollers if they fall on our rug. The untreated beechwood ring gives her a much harder surface to gnaw on when the soft silicone isn't cutting it, and it feels a bit more sustainable than buying mounds of plastic junk.

If your house is currently turning into a puddle of drool, you can look through the rest of Kianao's organic baby toys, but definitely get at least one silicone option and one wood option to see which texture your tiny dictator prefers.

My wife's strict rules on freezing

Before having a baby, my mental model for teething relief was just "give them frozen stuff." This is apparently terrible advice that I learned the hard way. Freezing a teething ring or a wet washcloth turns it into a rock-hard weapon that can really bruise their already swollen, agonizing gums.

Instead of building an arsenal of frozen plastic shrapnel in your icebox, you just put the silicone teethers or a damp, clean washcloth in the refrigerator for about twenty minutes so they get cool, but remain flexible. The cold helps numb the soreness, and you can massage their gums with your freshly washed finger while aggressively hoping they don't clamp down.

Maintenance protocols for tiny chiclets

The most unfair part of babies getting teeth is that the moment the tiny, razor-sharp sliver of white enamel breaks through the gums, you suddenly have to become a dental hygienist.

Dr. Aris informed us that dental care seriously starts before the tooth arrives. We were supposed to be wiping her gums with a damp cloth every night to remove bacteria, which I entirely failed to do for the first four months. Once the tooth is physically present in the mouth, you've to brush it twice a day with a soft infant toothbrush and a smear of fluoride toothpaste exactly the size of a grain of rice. Do you know how hard it's to measure toothpaste to the volume of a single grain of rice while a baby thrashes like a salmon? It requires immense focus. Also, never put them to bed with a bottle of milk, because the pooling sugars will cause something terrifyingly called "bottle rot," which sounds like a pirate disease but is genuinely just severe early tooth decay.

Before you dive into the frantic 3 AM google searches I've pre-answered below, just remember: grab that avocado teether, put it in the fridge, and accept that this particular biological firmware update takes as long as it takes.

Frequently Asked Questions I Googled at 4 AM

Do amber teething necklaces really do anything?

No, and my doctor practically jumped across the room to warn me about them. There's zero scientific evidence that the succinic acid in amber absorbs into the skin to relieve pain. More importantly, the AAP strongly warns against them because wrapping a string of tiny, breakable beads around a sleeping baby's neck is a massive strangulation and choking hazard. Stick to things they can safely hold in their hands.

Should I use those numbing teething gels from the pharmacy?

Absolutely not. The FDA has issued heavy warnings against over-the-counter teething gels containing benzocaine, and homeopathic tablets containing belladonna. Apparently, these can cause serious, life-threatening oxygen level issues in infants. When the pain is really bad, our doctor gave us the green light for a weight-appropriate dose of infant acetaminophen, but always ask your own doctor first instead of trusting a web search.

How do I clean wooden and silicone teethers without ruining them?

Silicone is amazing because you can just throw it in the top rack of the dishwasher or boil it for a few minutes to nuke the bacteria. Wood is trickier. If you soak wood in water or boil it, it'll swell, crack, and become a splinter hazard. I just wipe our wooden rings down with a damp, soapy cloth and let them air dry completely.

When are we supposed to really take the baby to a dentist?

The current guidance from both the AAP and the ADA is to book their first pediatric dental visit within six months of the first tooth popping through, or by their first birthday—whichever happens first. We went right around eleven months. It was mostly just the dentist looking quickly in her mouth, painting on a fluoride varnish, and assuring us we weren't ruining her life.
