Okay, let's talk baby teeth. Remember when you thought the biggest newborn challenge was diaper changes? Then suddenly your happy baby turns into a drooling, cranky mess chewing on everything. That's teething hitting you like a freight train. I've been through this twice with my kids, and let me tell you – nothing prepares you for the 3 AM screaming when those first teeth decide to show up.
So when do baby teeth come in exactly? Short answer: It's chaos wrapped in tiny gums. But after helping hundreds of parents through this (and surviving it myself), I've learned the patterns worth watching for.
Your Baby's Tooth Timeline: What to Expect Month by Month
Baby teeth don't follow military precision. My nephew got his first tooth at 4 months while my daughter waited until 9 months. Pediatric dentists say both are normal. But here's the general roadmap:
| Tooth Type | Average Eruption Age | Parent Survival Tip |
|---|---|---|
| Bottom front teeth (central incisors) | 6-10 months | Stock up on bibs – the drool floodgates open |
| Top front teeth (central incisors) | 8-12 months | Say goodbye to painless breastfeeding |
| Top lateral incisors (next to front teeth) | 9-13 months | Brace for bite marks on everything |
| Bottom lateral incisors | 10-16 months | Baby becomes a human piranha |
| First molars (back teeth) | 13-19 months | Worst pain phase – stock freezer with popsicles |
| Canines (pointy "vampire" teeth) | 16-23 months | Surprise! You thought teething was over |
| Second molars | 23-33 months | Final boss battle of teething |
See that 6-33 month range? That's why "when do baby teeth come in" is such a hot search. Your neighbor's baby might have a full grin at 18 months while yours is still gummy at 12 months – both can be perfectly fine.
Personal Teething Hack: We used frozen washcloths because my kid hated store-bought teethers. Just dunk a clean cloth in breastmilk or water, freeze it, and let them gnaw. Worked better than that $25 giraffe everyone recommends.
Spotting Teething: Is This Normal or Something Worse?
Teething mimics half a dozen illnesses. Here's how to decode your baby's signals:
Classic Teething Signs
- Drool Tsunami: Seriously, change shirts constantly unless you enjoy wet patches
- Crankiness that comes in waves (like tiny angry tides)
- Chewing obsession (fingers, toys, your shoulder – nothing's safe)
- Swollen gums that look bruised-ish
- Mild temperature (under 100.4°F/38°C – higher means call the doc)
Red Flags That Aren't Teething
- Diarrhea or vomiting (science says teething doesn't cause this)
- Rash everywhere (drool rash stays around mouth/chin)
- High fever (101°F/38.3°C+)
- Lethargy or refusal to drink
I made the mistake of blaming every fussy phase on teething. Turned out my son had an ear infection that needed antibiotics. Don't be like me – if something feels off, trust your gut and call your pediatrician.
Teething Relief That Actually Works (And What's a Waste of Money)
After trying every remedy known to Pinterest, here's what actually helps:
| Remedy | How to Use | Effectiveness Rating (1-5) |
|---|---|---|
| Cold teething rings | Chill (don't freeze solid) and supervise use | ★★★★☆ |
| Gum massage | Clean finger, gentle pressure | ★★★☆☆ |
| Chilled fruit in mesh feeder | Frozen banana or berries | ★★★★★ (my kids loved this) |
| Over-the-counter gels | Sparingly at pediatrician's advice | ★★☆☆☆ (numbing effect fades fast) |
| Acetaminophen | For brutal nights after doctor approval | ★★★★☆ |
Avoid amber teething necklaces. Not only did mine do nothing, but the AAP warns they're choking hazards. Also skip whiskey on gums – yes, Grandma suggests it, no, it's not safe.
Caring for Those New Pearly Whites
First tooth spotted? Time to brush. Here's what dental hygienists told me:
- Tool Upgrade: Start with silicone finger brush → graduate to soft baby toothbrush
- Toothpaste Rule: Rice-sized smear of fluoride toothpaste once teeth touch
- Brushing Battle Tip: Sing stupid songs. My go-to was "This is the way we brush our teeth" to the tune of Here We Go Round the Mulberry Bush
First dental visit should happen when the first tooth appears or by age 1 – whichever comes first. Our dentist found early decay between my daughter's front teeth we'd missed. Lesson learned.
When Teeth Are Late: Should You Panic?
If you're googling "when do baby teeth come in" at 15 months with zero teeth, breathe. Reasons for delays:
- Genetics (ask your parents when you got teeth)
- Premature birth (adjust for prematurity)
- Nutrition gaps (vitamin D matters)
But get an X-ray if:
- No teeth by 18 months
- Teeth erupt in bizarre positions
- Jaw looks swollen or painful
From Baby Teeth to Big Kid Teeth: The Transition
Baby teeth don't last forever (thank goodness). Here's what comes next:
- First to Leave: Bottom front teeth around age 6
- Molar Mayhem: First permanent molars erupt behind baby molars around age 6-7
- Full Swap: Most baby teeth are gone by age 12 (wisdom teeth are a teenage nightmare)
Your Top Teething Questions Answered
Q: Can teething cause diaper rash?
A: Indirectly. All that drool swallowing changes poop consistency which irritates skin. Use barrier cream preemptively.
Q: When do baby teeth come in for preemies?
A: Track by adjusted age. Our 2-month-premature son got teeth at 8 months actual (6 months adjusted).
Q: Are silver caps on baby teeth normal?
A: Yep, if there's decay. My niece has two. They protect until the tooth falls out naturally.
Q: How long does teething pain last per tooth?
A> Usually 2-7 days of active misery per tooth. Molars drag on longer though.
Q: Do babies reject food when teething?
A> Temporarily. Offer cold applesauce or yogurt instead of warm oatmeal during flare-ups.
Final Reality Check
Look, teething sucks. There's no magic fix. That fancy vibrating teether? My kid stared at it like alien tech then chewed the sofa instead. But it ends. One morning you'll realize they slept through the night and there's a tiny white cap poking through.
When parents ask me "when do baby teeth come in," I say: Whenever your kid decides. Track symptoms, trust your instincts, and remind yourself this phase fades faster than those newborn onesies. Now pass the coffee – you've got this.
