Most infants cut their first tooth around 6 months, with a normal window from about 4 to 12 months.
That first tooth can feel like it takes forever, then it shows up out of nowhere. One day your infant is all gummy smiles. The next day there’s drool on every bib and a new habit of chewing anything within reach.
If you’re asking when do infants get their teeth?, you’re really asking two things: what’s common, and what’s still normal. You’ll get both here, plus a practical routine for easing sore gums and protecting new teeth once they arrive.
Tooth Eruption Timeline By Month
Teeth don’t pop in on a perfect schedule. Some babies get a first tooth before 4 months. Others don’t show one until after 12 months. A first tooth near 6 months is common, and the first teeth are often the lower front pair.
| Age Range | Teeth Often Erupting | What Parents Commonly See |
|---|---|---|
| 0–3 months | No eruption yet | Hands to mouth, chewing motions, gum ridges you can feel. |
| 4–7 months | Lower central incisors | Drool, red cheeks, gnawing, brief fussiness that comes and goes. |
| 6–10 months | Upper central incisors | Biting during feeds, a sharp edge under a puffy gum line. |
| 9–12 months | Upper and lower lateral incisors | Front teeth fill in beside the first pair; more interest in textures. |
| 12–16 months | First molars | More chewing, sleep bumps, thicker drool during new tooth movement. |
| 16–20 months | Canines | Pointy teeth near the corners; gum tenderness can flare for a few days. |
| 20–30 months | Second molars | Last baby molars arrive; big chewing urge, more hand-in-mouth time. |
| By age 3 years | All 20 baby teeth | A full set is in; brushing habits matter more than tooth timing. |
The month bands above are ranges, not deadlines. A tooth can sit just under the gum for weeks, then break through in a day. You might also see two teeth arrive close together, then a quiet stretch.
When Do Infants Get Their Teeth? What The Range Means
Most infants get their first tooth in the first year, often near 6 months. If your baby is earlier than that, it can still be fine. If your baby is later, it can still be fine too. Tooth timing runs in families, so ask grandparents when their kids started teething. You may get a clue.
If your infant is past 12 months with no teeth, it’s worth bringing up at a well visit. It doesn’t mean there’s a problem, but it’s a clean moment to review growth, feeding, and any medical history that might affect eruption.
What Changes Tooth Timing
Family Pattern
Genes carry a lot of weight here. Some families are “early teeth” families. Others are “late teeth” families. If everyone in your family got teeth late, your baby may follow that pattern.
Teething Signs That Fit The Pattern
Teething can be loud or quiet. Some infants barely react. Others feel it in their whole body and act out of sorts for a few days. The timing can also throw you off. Discomfort can start before the tooth breaks through.
Common Signs
- More drool and a wet rash on the chin or chest
- Chewing, gnawing, or biting harder than usual
- Gums that look swollen or feel firm in one spot
- Short bursts of fussiness, often worse in the evening
- Sleep bumps that improve once the tooth breaks through
Signs That Point Away From Teething
Teething can come with mild irritability, but it shouldn’t explain big symptoms that keep climbing. If your baby has a fever, vomiting, persistent diarrhea, trouble breathing, or a rash spreading fast, treat it as illness, not teeth.
One helpful habit: track the pattern. Teething flare-ups often come in short waves, then ease. Illness tends to keep building until it’s treated or runs its course.
Ways To Soothe Sore Gums
Relief is mostly about pressure and cool touch. Keep it simple, and keep it safe. Anything that goes in the mouth needs to be clean, hard to break, and sized so it can’t slip back into the throat.
Cooling And Pressure Ideas
- Cold washcloth: Wet, wring out, chill, then let your baby chew while you supervise.
- Chilled teething ring: Cool in the fridge, not the freezer, so it stays gentle on gums.
- Finger massage: Use a clean finger to rub the sore spot for 30–60 seconds.
- Firm foods with supervision: A peeled, chilled cucumber spear can work for older babies who handle solids well.
Medication Notes Without Guesswork
If your baby seems truly uncomfortable, ask your pediatric clinician about pain medicine dosing for your child’s age and weight. Skip numbing gels unless your clinician tells you to use a specific product. Many oral gels are not meant for infants, and it’s easy for them to be swallowed.
How To Care For New Teeth From Day One
Baby teeth are small, but they can still get cavities. Start with a simple routine and stick with it. The goal is to wipe away milk and food, then keep sugar from sitting on teeth for hours.
Before Teeth Erupt
Even before you see a tooth, you can wipe gums once a day with a clean, damp cloth. It’s quick. It also helps your baby get used to mouth care, which makes brushing less of a fight later.
Once The First Tooth Shows
Brush twice a day with a soft infant toothbrush. Use a smear of fluoride toothpaste for children under 3, about the size of a grain of rice. This aligns with guidance summarized by the CDC in its toothbrushing recommendations for young children (fluoride toothpaste guidance).
If your baby fights the brush, try this: sit your baby facing away on your lap, tip their head back against your chest, and brush fast. Make it a short routine, then move on with the day.
Night Feeding And Teeth
Milk has natural sugars. If your baby falls asleep after feeding, leftover milk can sit on teeth. You don’t need to panic, but it helps to wipe teeth and gums after the last feed when you can. If your baby wakes often to feed, do your best with the routine you can keep.
First Dental Visit Timing
Many pediatric dental groups recommend a first dental visit by age 1, or within six months of the first tooth. It’s a short visit. You get a quick oral check, brushing coaching, and guidance on thumb sucking, pacifiers, and cavity risk. The American Academy of Pediatric Dentistry explains the rationale in its policy document on the age one dental visit.
Not sure how to find a pediatric dentist? Your pediatric clinic can point you to local options. You can also ask your own dentist if they see infants, since many do.
Situations That Merit A Call
Most teething days are uncomfortable but plain. Still, there are moments when it’s better to check in. You know your baby’s normal. If something feels off, trust that instinct.
Call Soon If You Notice
- No teeth by about 12 months
- A tooth that looks chipped right as it erupts
- White or brown spots on teeth that don’t brush off
- Bleeding gums that don’t calm with gentle brushing
- Ongoing mouth sores or a bad smell that sticks around
If your baby is born with a tooth or a tooth erupts in the first month, it can still be normal, but it’s worth a prompt dental check. Early teeth can be loose and can rub the tongue during feeds.

Quick Reference Checklist For The First Two Years
When the days blur together, a small checklist keeps you steady. This is the same set of steps many clinicians repeat in visits, just written in parent language.
- Track the first tooth month, not the exact day.
- Start brushing twice daily as soon as a tooth shows.
- Use a rice-grain smear of fluoride toothpaste for under-3s.
- Offer cold, safe chewers during sore-gum days.
- Watch for illness signs that don’t match teething patterns.
- Plan a dental visit by age 1 or within six months of first tooth.
- Ask about fluoride exposure if you use well water.
Still asking when do infants get their teeth? First tooth around 6 months is common too. Soothe safely, brush once teeth arrive.
| What You Notice | What It Can Point To | Next Step |
|---|---|---|
| Drool rash on chin or chest | Teething drool irritation | Pat dry, use a thin barrier ointment, change bibs often. |
| Gum bulge with a pale spot | Tooth close to breaking through | Cold washcloth or gentle finger massage. |
| Fussiness in short waves | Tooth movement under the gum | Extra comfort, safe chewing, keep routines steady. |
| Fever or symptoms that keep rising | Illness, not teething | Follow your pediatric clinic’s sick-day guidance. |
| No tooth by about 12 months | Late eruption pattern | Bring it up at the next well visit or dental visit. |
| White lines or spots on teeth | Early enamel change | Book a dental check; review brushing and feeding habits. |
| Tooth looks dark or bruised | Possible trauma or enamel issue | Call a dentist for advice and timing. |
