Understanding the Eruption of Primary Teeth
At Sky Pediatric Dentistry, we know that your child’s dental journey begins long before their first tooth appears. In fact, primary teeth (also known as baby or deciduous teeth) start forming beneath the gums as early as the fourth month of pregnancy. That’s why a healthy prenatal diet is essential—not only for your baby’s overall development but also for strong teeth, gums, and bones.
When Do Baby Teeth Come in?
Most babies begin teething between six months and one year of age, with the lower front teeth (central incisors) usually appearing first. By the age of three, most children will have a complete set of 20 primary teeth.
The American Dental Association (ADA) recommends scheduling your child’s first visit to a pediatric dentist about six months after their first tooth erupts. At Sky Pediatric Dentistry, we make this “well-baby” visit a comfortable and educational experience, offering tips to create a tear-free, effective home care routine.
Why Are Baby Teeth Important?
Although baby teeth are temporary, they play a vital role in your child’s health and development. They help with:
- Clear speech development
- Proper chewing and nutrition
- Healthy jaw growth
- Holding space for adult (permanent) teeth
Caring for baby teeth helps prevent cavities, early tooth loss, gum disease, and even potential nutritional problems caused by pain or infection.
In What Order Do Baby Teeth Appear?
Here's a general guide to the eruption timeline for primary teeth:
- Central Incisors (Front Teeth): Lower and upper jaws, 6–12 months. These are typically the first to emerge—and the first to fall out around age 6–7.
- Lateral Incisors: Just beside the central incisors, 9–16 months. These usually fall out between 7–8 years of age.
- First Molars: Toward the back of the mouth, 13–19 months. These can cause teething discomfort. Try cool gauze, clean fingers, or teething rings for relief. They’re lost around 9–11 years old.
- Canines (Cuspids): Next to the lateral incisors, 16–23 months. These typically fall out between 10–12 years of age.
- Second Molars: At the very back of the mouth, 23–33 months. These are the last baby teeth to arrive and are generally lost around 10–12 years old.
Fun Facts About Baby Teeth
- Lower teeth often emerge before their upper counterparts.
- Teeth tend to erupt in pairs—so don’t be surprised if two come in at once.
- Baby teeth are smaller and whiter than permanent teeth.
- It’s normal for school-aged children to have a mix of baby and adult teeth.
