Tooth Eruption Chart for Kids: When Do Teeth Come In?

Every child grows at their own pace—and that goes for their teeth, too. Some babies cut their first tooth at 4 months; others don't see one until after their first birthday. Both can be completely normal. Understanding the tooth eruption chart for kids helps parents track these milestones, spot potential issues early, and feel confident that development is on the right track.

This guide covers everything parents need to know: when baby teeth appear, when they fall out, and when permanent teeth take their place. You'll also find practical tips for keeping erupting teeth healthy and clear guidance on when it's worth calling your pediatric dentist.

What Is a Tooth Eruption Chart?

A tooth eruption chart is a reference tool that maps out the average ages at which each tooth appears and, for baby teeth, when it's expected to fall out. Pediatric dentists use these charts during routine checkups to assess whether a child's dental development is progressing normally.

For parents, a tooth eruption chart offers several benefits:

• Tracks dental milestones so you know what to expect at each age
• Helps identify delayed eruption that may warrant a professional evaluation
• Monitors tooth loss to ensure the transition to permanent teeth is smooth
• Supports preventive dental care by flagging the right time to start certain treatments

Think of it as a road map—not a strict schedule—for your child's smile.

Tooth Eruption Chart for Kids (Baby Teeth Timeline)

Most children grow 20 baby teeth, also called primary teeth or deciduous teeth. These begin appearing around 6 months of age and continue erupting through the toddler years.

Average Baby Tooth Eruption Schedule

Most children have a full set of 20 baby teeth by age 3. One important thing to keep in mind: the order of eruption typically matters more than the exact timing. If teeth are appearing in a reasonable sequence—even if a few months "late"—there's usually no cause for concern.

When Do Kids Lose Their Baby Teeth?

Baby teeth start loosening and falling out to make room for permanent teeth, typically beginning around age 6. Children often lose their teeth in roughly the same order they came in.

Baby Tooth Loss Chart

A few things worth knowing during this phase. A tooth that's loosening naturally will gradually become wigglier over days or weeks—that's normal. Avoid pulling a loose tooth before it's ready. Forced removal can cause unnecessary pain or infection if the root hasn't fully dissolved. Let the child wiggle it themselves. When it comes out on its own, the root is typically gone and the area heals quickly.

Parents should also expect some overlap: a child may be losing their first baby teeth while newer ones are still falling out elsewhere. This process continues well into the early teen years.

Permanent Tooth Eruption Chart

As baby teeth fall out, 32 permanent teeth gradually take their place. This transition spans from around age 6 all the way through early adulthood.

Adult Teeth Timeline

Wisdom teeth are the final four permanent teeth to arrive—and they don't always show up at all. Not everyone develops wisdom teeth, and when they do, they frequently cause crowding or alignment issues that require removal. Your child's dentist will monitor them as part of routine care.

Signs a Tooth Is About to Erupt

Teething can be uncomfortable for babies and toddlers. Common signs that a tooth is working its way through include:

• Increased drooling
• Swollen or red gum tissue
• Mild fussiness or irritability
• A strong urge to chew on objects
• Slight decrease in appetite
• Mild disruption to sleep

These symptoms are manageable. A clean, chilled teething ring or a gentle gum massage can provide relief.

However, some symptoms are not typical signs of teething and should be evaluated by a doctor:

• High fever (over 101°F)
• Severe diarrhea
• Persistent vomiting
• Any signs of significant illness

Teething does not cause fever. If your child is running a temperature alongside tooth eruption, the two are likely unrelated—and the illness deserves its own attention.

Why Tooth Eruption Timing Can Vary

Seeing another child with a full set of teeth while yours has none yet? Don't panic. Many factors influence when teeth arrive.

Genetics

Family history plays a big role. If you or your partner were early or late teethers, there's a good chance your child will follow a similar pattern.

Nutrition

Adequate calcium, vitamin D, and phosphorus support healthy dental development. Nutritional deficiencies, particularly in early childhood, can sometimes delay eruption.

Premature Birth

Babies born prematurely may reach dental milestones later than peers born at full term. Adjusting for gestational age often puts their development right on track.

Overall Growth and Development

Children who are smaller or develop more slowly overall may also experience later tooth eruption. This is typically not a cause for concern on its own.

Certain Medical Conditions

Some conditions—including hypothyroidism, Down syndrome, and certain genetic disorders—can affect the timing and pattern of tooth eruption. A pediatric dentist can help determine whether further evaluation is needed.

Differences of several months from the average are common and usually within the range of normal. The charts above are guides, not guarantees.

When Should Parents Be Concerned?

While variation is normal, certain situations do warrant a dental checkup. Reach out to a pediatric dentist if you notice:

• No teeth by 18 months of age
• Teeth erupting far outside the expected ranges listed above
• Permanent teeth not appearing after baby teeth have fallen out (allowing more than 6 months)
• Baby teeth that aren't loosening when they should be
• Significant crowding or unusual spacing
• Swelling or persistent pain around an erupting tooth
• Any history of dental trauma that may affect tooth development

Catching these issues early gives your dentist more options—and often simpler solutions.

Caring for Erupting Teeth

Good habits built during these early years pay off for a lifetime. Here's how to protect your child's teeth as they come in:

Brush Twice Daily: Use a soft-bristled toothbrush and age-appropriate fluoride toothpaste—a smear the size of a grain of rice for children under 3, and a pea-sized amount for children 3 and older.

Begin Flossing: Start flossing as soon as two teeth are touching. Food and bacteria can get trapped between teeth long before children can do this independently.

Eat a Tooth-Friendly Diet: Limit sugary drinks, juices, and sticky snacks. These feed the bacteria that cause cavities.

Encourage Water: Water helps rinse away food particles and, when fluoridated, supports stronger enamel.

Avoid Baby Bottle Tooth Decay: Never put a baby to bed with a bottle of milk or juice. Pooling sugary liquid around new teeth overnight is one of the most common causes of early childhood cavities.

Schedule Regular Dental Checkups: The American Academy of Pediatric Dentistry recommends a first dental visit by age 1, then checkups every six months. Early visits help children become comfortable in the dental chair—and give your dentist a chance to catch problems before they grow.

Every Smile Has Its Own Timeline

Understanding the tooth eruption chart for kids takes a lot of the guesswork out of your child's dental development. You'll know roughly when to expect each tooth, what to watch for, and when something is worth a second opinion.

The most important takeaway: most variations in timing are completely normal. What matters most is keeping up with regular dental visits, maintaining good oral hygiene at home, and staying aware of the milestones outlined in this guide.

If something feels off—a tooth that's very late, crowding that seems significant, or a permanent tooth that hasn't arrived—trust your instincts and book an appointment. Early evaluation is always worthwhile.
