Infant Teeth Growth: Stages, Care, and Tips

A baby’s teeth, also known as primary teeth or milk teeth, begin developing before birth but usually start appearing between 4 to 7 months of age. Proper care from the start ensures healthy infant teeth growth and also helps gums as they grow.

Stages of Infant Teeth Growth

1. In the Womb    

A baby’s teeth begin forming in the second trimester (around 6 weeks of pregnancy).

– By birth, all 20 primary teeth are already present in the gums.

2. Teething Stage (4–12 Months)

– The first tooth typically appears around 6 months, though it can be earlier or later.

– Lower central incisors (bottom front teeth) come first, followed by the upper central incisors.

• Signs of teething include:

– Excessive drooling

– Irritability or fussiness

– Chewing on objects

– Swollen or tender gums

3. Full Set of Baby Teeth (By Age 3)

Most children will have all 20 primary teeth by their third birthday.

– These teeth will later be replaced by permanent teeth, starting around age 6.

How to Care for an Infant’s Teeth

Before Teeth Erupt

– Clean the baby’s gums with a soft, damp cloth after feedings.

After Teeth Appear

– Brush gently with a soft-bristled toothbrush and water twice a day.

– Use a tiny smear of fluoride toothpaste (about the size of a grain of rice) for babies under 3 years.

Preventing Tooth Decay

– Avoid putting the baby to sleep with a bottle of milk or juice (bottle rot can occur).

– Limit sugary foods and drinks.

– Schedule the first dental visit by the baby’s first birthday.

Helping with Teething Discomfort

– Give a clean, chilled teething ring (not frozen).

– Gently rub the baby’s gums with a clean finger.

– Offer cold, soft foods (like yogurt or applesauce) if the baby has started solids.

– Use pain relief options (like baby-safe teething gels or pediatrician-approved medicine) if needed.

Conclusion

Infant teeth growth is a natural process that requires proper care to ensure healthy development. Establishing good oral hygiene early helps prevent cavities and sets the foundation for strong permanent teeth.
