Man, I remember when my niece started teething. My sister called me at midnight completely freaked out because the baby wouldn't stop crying and was chewing on everything. "Is this normal?" she asked. "When do babies even start teething?" That's when I realized how confusing this whole teething timeline can be.
So let's cut through the noise. When does teething start? Most babies get their first tooth between 4 and 7 months old. But here's the thing - that's just an average. Our pediatrician told us about babies who popped teeth at 3 months and others who waited until their first birthday. Nature doesn't follow our calendars.
With my nephew, we were checking his gums daily from month 3 onward. Nothing. Then at 8 months - bam! Two bottom teeth appeared within a week. Kids keep you humble.
The Real Teething Timeline Explained
That burning question - when does teething start - deserves a proper breakdown. Forget vague answers. Here's what actually happens:
| Age Range | Likelihood of First Tooth | Common Teeth | What We Usually See |
|---|---|---|---|
| 0-3 months | Rare (less than 1%) | None typically | Usually just drooling, no actual teeth |
| 4-7 months | Most common timing (about 60-70%) | Bottom front teeth (central incisors) | Classic teething signs appear |
| 8-12 months | Very common (covers most remaining) | Top front teeth, then lateral incisors | Multiple teeth may emerge close together |
| 12+ months | Less common (about 5-10%) | First molars often appear late | Pediatrician check recommended if no teeth |
I've seen moms stress when their 5-month-old has no teeth while their friend's 4-month-old has two. Honestly? Both are normal. Teeth show up when they're good and ready.
Early Teethers vs Late Bloomers
Let's get real about early starters. When teething starts before 4 months, it's unusual but not alarming. Genetics often play a role - ask when you and your partner got teeth. Late teething (after 12 months) happens too. My cousin's kid didn't get teeth until 14 months! Turned out fine, just took longer.
Pediatric tip: If no teeth by 18 months, see your dentist. Could indicate nutritional issues (like low vitamin D) or rare syndromes. But usually? Just a slow starter.
How to Spot Teething Symptoms (And Not Mistake Them for Illness)
Teething signs can be sneaky. Before we knew when teething starts for real, my sister kept blaming every drool spot and fussy night on teeth. Half the time it was just normal baby stuff.
- The classic signs: Excessive drooling (like soaking through shirts), chewing on everything (fingers, toys, your shoulder), swollen gums that look bruised, mild temperature (under 100.4°F/38°C)
- Less obvious hints: Ear pulling (referred pain), facial rash from drool, disrupted sleep patterns, slight appetite changes
- What's NOT teething: High fever (over 101°F/38.3°C), diarrhea, full-body rash. That's likely illness. Don't blame the teeth!
Major red flag: Some parents mistake hand/foot/mouth disease for teething. If they have mouth sores AND a rash on hands/feet? Doctor time.
When does teething discomfort peak? Usually 3-5 days before tooth breaks through gums. My trick? Gently rub a clean finger over gums. If you feel a sharp little ridge under the surface? Tooth's coming.
Stages of Teething Pain and What Actually Helps
Teething isn't constant pain. It comes in waves. Knowing these stages helps you respond:
| Phase | Duration | Pain Level | Best Relief Methods | What Often Fails |
|---|---|---|---|---|
| Early Stage (tooth moving beneath gum) | 1-2 weeks | Mild to moderate | Chewing on chilled (not frozen) teethers, gum massage | Medication (too early), hard toys |
| Breakthrough Stage (tooth cutting through gum) | 3-7 days | Peak discomfort | Cold washcloths, FDA-approved numbing gels, infant pain relievers (if pediatrician approves) | Homeopathic tablets (questionable safety), amber necklaces (choking risk) |
| Post-Eruption (tooth fully emerged) | 2-3 days | Rapidly decreases | Normal chewing, soft foods if gums are tender | Continuing medication unnecessarily |
Cold is magic for sore gums. We used to freeze breastmilk in ice cube trays and wrap cubes in muslin cloth. Baby gnaws, gets relief, and swallows nutritious milk. Win-win.
Teething Remedies That Work (And Some I'd Avoid)
After three nieces/nephews, I've tested everything:
- Winners: Rubber teethers with nubs (chilled), silicone feeder with frozen fruit, clean finger massage, occasional infant acetaminophen (worst nights only)
- Meh: Wooden teethers (too hard), vibration toys (some babies hate the buzz)
- Skip these: Topical benzocaine gels (FDA warns against for infants), alcohol-based remedies, teething necklaces (serious strangulation risk)
One mom in my group swore by rubbing whiskey on gums. Seriously? Just no. Modern solutions exist.
Confession: I wasted $25 on a fancy "natural" teething oil. Smelled nice but did squat. Pediatrician said "cold washcloths work better." She was right.
Your Baby's Tooth Timeline: What Comes Next
Once you know when teething starts, you'll wonder about the rest. Here's the typical order (though variations are normal):
| Tooth Type | Average Eruption Age | Fun Fact | Special Care Tips |
|---|---|---|---|
| Lower central incisors (bottom front) | 6-10 months | Often erupt in pairs | Easiest to clean with soft cloth |
| Upper central incisors (top front) | 8-12 months | Creatores the classic "two front teeth" look | May cause increased drooling |
| Upper lateral incisors (next to front) | 9-13 months | Often have slight gaps (normal) | Introduce baby toothbrush |
| Lower lateral incisors | 10-16 months | Complete the "front eight" | Watch for lip biting as they adjust |
| First molars (back teeth) | 13-19 months | Largest so far, cause significant discomfort | Chewing pressure helps - offer firm foods |
| Canines (pointy "fangs") | 16-23 months | Often cause gum swelling | Extra cuddles needed - painful eruption |
| Second molars | 23-33 months | Final baby teeth | Establish regular brushing routine |
Notice how the timing overlaps? That's why some kids seem perpetually teething between 6-30 months. Hang in there!
Why Teething Order Matters
Those molars at 13-19 months? Brutal. Bigger surface area means more inflammation. That's when parents often ask "when does teething start being this painful?" Unfortunately, later teeth often hurt more.
Fun fact: The tooth fairy's first visit usually happens around age 6-7 when permanent teeth replace baby teeth. But that's another adventure.
Top Parent Questions About When Teething Starts
Let's tackle those burning questions real parents ask about when teething begins:
Can teething start at 2 months?
Possible but rare. Before 4 months, "teething symptoms" are usually just normal baby development. True tooth eruption under 3 months is unusual - less than 1% of babies.
Why is my 3-month-old drooling but no teeth?
Drool factories kick in around 2-3 months regardless of teeth. Babies don't yet swallow saliva effectively. Unless you feel a tooth ridge under gums, it's likely not teething.
Is late teething a sign of developmental delay?
Usually not. Genetics heavily influence teething timelines. However, if paired with other delays (not sitting by 9 months, no babbling), mention it to your pediatrician.
Do breastfed babies teethe later?
Myth. Multiple studies show no link. My exclusively breastfed nephew got teeth at 5 months while his formula-fed cousin started at 7. Feeding method doesn't dictate when teething starts.
How long does teething pain last per tooth?
Peak discomfort lasts about 3-5 days when tooth breaks through gums. Mild symptoms may linger 1-2 weeks before and after. The whole "teething journey" spans about 2 years!
Can early teething affect breastfeeding?
Possibly. Some babies bite during nursing when teeth emerge. If this happens, break suction gently and say "no bite." Usually temporary. Consult lactation consultant if persistent.
Still worried about when teething starts for your child? Trust me, you'll know when it happens. That distinctive "crunch" when they bite a teether? Unmistakable sound of a new tooth breaking through.
Essential Teething Toolkit Every Parent Should Have
After surviving multiple teething babies, here's what actually deserves space in your diaper bag:
- Must-haves: Multiple silicone teethers (rotate as they get dropped), absorbent bandana bibs (better than regular bibs for drool), teether clips (attach to stroller), infant toothbrush (start early)
- Med cabinet: Infant acetaminophen or ibuprofen (check age limits), saline wipes for drool rash
- DIY solutions: Clean wet washcloths (keep in fridge), frozen banana in mesh feeder, chilled spoon
- Skip: Teething mittens (babies hate them), fancy vibrating toys (most end up forgotten), homeopathic gels (effectiveness unproven)
Pro tip: Rotate teethers. When one hits the floor, swap with a clean one. Keep 2-3 in rotation so you always have a chilled one ready.
When Should You Call the Doctor?
Most teething is DIY care. But call your pediatrician if you see:
- Fever over 101°F (38.3°C) - unlikely caused by teething alone
- Diarrhea lasting more than 2 bowel movements
- Gums with pus or severe swelling
- No teeth by 15 months
- Refusing all liquids for over 8 hours
We once mistook an ear infection for teething. Baby pulled ears and was fussy. Turned out unrelated. Trust your gut - if symptoms seem excessive, get it checked.
Dental Care From Day One (Yes, Even Before Teeth!)
Once you know when teething starts, dental care begins. Many parents wait too long. Our pediatric dentist shared these milestones:
| Age | Dental Care Action | Why It Matters |
|---|---|---|
| Before teeth erupt | Wipe gums with clean damp cloth after feeds | Removes bacteria, acclimates baby to oral care |
| First tooth appears | Start brushing twice daily with rice-grain sized fluoride toothpaste | Prevents "bottle caries" on new teeth |
| By 1st birthday | First dental check-up | Early cavity detection, establishes dental home |
| Multiple teeth present | Introduce flossing where teeth touch | Prevents cavities between teeth |
Start early and make it fun. We used to sing silly toothbrushing songs. Now my nephew actually reminds his mom when it's "tooth time."
Critical mistake: Putting baby to bed with bottle (except water). Milk pooling around new teeth causes rapid decay called "bottle rot."
Final Thoughts: Riding the Teething Rollercoaster
Wondering when teething starts keeps many parents up at night. As a mom who's been through it, my best advice? Don't pre-stress about timelines. Teeth come when they come. Track symptoms, not calendars.
Those tough nights? They pass. My sister still laughs about how she panicked during her firstborn's teething. By her third kid, she'd just hand the baby a chilled carrot and go back to sleep. You'll find your rhythm.
Every child's journey differs. Focus on soothing your baby through discomfort rather than comparing timelines. Before you know it, you'll miss that gummy smile. Now pass the teething rings and coffee - you've got this.
