Every child develops at their own pace, but when it comes to baby teeth, many New Zealand parents worry if their little one seems to be teething later than expected. On average, the first baby tooth appears between 6–10 months—but for premature or low-birth-weight babies, this timeline can be noticeably different.
At Howick Dental Surgery, we often reassure parents from across East Auckland that delayed tooth eruption can be perfectly normal for babies who arrived early. Still, it helps to understand why this happens and when to seek dental advice.
Why Premature Babies Often Get Their Teeth Later
Research from paediatric and dental health organisations shows a clear pattern:
Premature birth can shift the teething timeline by weeks or even months.
This is because a baby’s tooth development begins in the womb. When the baby is born early:
- Tooth formation may be less advanced at birth
- Mineralisation (the hardening of tooth structures) may be delayed
- Growth rate is often slower in the first months
- Overall physical development—including oral tissues—takes longer to catch up
Most commonly, children born before 37 weeks show:
- Later eruption of the first tooth
- More spacing between teeth
- Slight enamel differences
- Delayed emergence of molars
This delay is usually harmless and balances out with time.
The Role of Low Birth Weight
Babies under 2.5 kg at birth often experience similar delays, even if they were not significantly premature. Low birth weight can be linked to:
- Slower jaw development
- Reduced mineral content in developing teeth
- Nutritional challenges in early infancy
Because tooth germs (early tooth structures) need consistent nutrients to develop, babies who start life small sometimes need a little extra time for their teeth to break through the gums.
What This Means for Your Baby’s Oral Health
Delayed baby teeth do not usually mean delayed adult teeth or long-term dental problems. However, some premature or low-weight babies may be more prone to:
- Enamel defects (weaker or chalky enamel)
- Spotting or grooves on baby teeth
- Higher risk of early decay
- Delayed jaw development
This is why early dental monitoring is helpful, even before the first tooth appears.
When Should Parents Be Concerned?
See a paediatric dentist or book a visit with Howick Dental Surgery if:
- No teeth have erupted by 18 months
- Teeth appear but look unusually soft or discoloured
- Your baby has difficulty chewing once solids are introduced
- You notice signs of discomfort not typical of normal teething
There is a history of extreme prematurity (under 32 weeks)
Early assessment helps ensure that any enamel or developmental concerns are managed sooner rather than later.
How Parents Can Support Healthy Tooth Development
Simple habits can make a big difference—especially for babies who were premature or low-weight:
- Clean gums daily with a soft cloth
- Begin brushing as soon as the first tooth appears
- Introduce mineral-rich foods as recommended by your GP
- Avoid putting babies to sleep with milk bottles
- Ensure good vitamin D intake (sunlight or supplements if advised)
- Book their first dental visit by age one
These steps help protect the enamel and encourage a strong start to oral health.
