Somebody in your family WhatsApp group will mention their baby's first tooth at 4 months, and somewhere else another baby is 9 months old with a perfectly empty, gummy smile. Both of those babies are doing exactly fine. Tooth timing has one of the widest 'normal' ranges in early childhood development, and most of the anxiety around it comes from comparison rather than anything actually being wrong.
The Realistic Range
Most babies get their first tooth somewhere between 4 and 7 months. That's the average window - but 'average' hides a lot of genuinely normal variation. Some babies are born with a tooth already through (rare but not a medical concern on its own). Others don't get their first tooth until closer to their first birthday. Family pattern plays a real role here - if a parent teethed late, their baby often does too.
The Usual Order (Not a Rule, Just a Pattern)
|
Typical Age |
Teeth |
Common Name |
|
6-10 months |
Bottom two front teeth |
Lower central incisors |
|
8-12 months |
Top four front teeth |
Upper incisors |
|
9-13 months |
Bottom lateral incisors |
Bottom side teeth |
|
13-19 months |
First molars |
Back chewing teeth |
|
16-22 months |
Canines |
Pointed side teeth |
|
23-33 months |
Second molars |
Final back teeth |
By around age 3, most children have all 20 baby teeth. This order is a general pattern, not a strict rule - plenty of babies get teeth slightly out of this sequence with no issue at all.
Why the Range Is So Wide
Tooth eruption timing is influenced by genetics more than almost anything a parent does. Nutrition and general health play a small role, but a healthy baby teething at 4 months and a healthy baby teething at 11 months are both simply following their own individual timeline - not one doing better than the other.
When Late Teething Is Worth Mentioning
A baby with no teeth by their first birthday is still usually within a normal, if later, range - but it's a reasonable thing to bring up at your paediatric check-up rather than something to research anxiously at home. Your paediatrician can check gum development and rule out the rare underlying causes of significantly delayed teething, which are usually accompanied by other signs, not an isolated late tooth.
What About Teeth That Arrive Very Early?
A tooth appearing before 4 months, or a baby born with one already present (natal teeth), isn't necessarily a concern, but it is worth mentioning to your paediatrician - mainly to check the tooth is stable and not at risk of coming loose, which could be a choking concern.
