Baby Teeth Timeline: What to Expect from Teething to Molars

Baby teeth don’t appear overnight—though it can certainly feel that way when your little one suddenly becomes fussy, drooly, and eager to chew on anything within reach. The arrival of those first teeth is a major developmental milestone, and knowing what to expect can make the process much easier for both baby and parent.

In this article, we’ll guide you through the signs of teething, the baby tooth eruption stages, and when to expect molars. You’ll also learn how to use a baby teeth chart to track progress and support your child’s dental health every step of the way.

When Do Babies Start Teething?

Most babies begin teething around 6 months old, although some may start earlier or later. Every baby is different, but common teething symptoms include:

  • Excessive drooling

  • Crankiness or irritability

  • Chewing on hands, toys, or anything nearby

  • Sleep disruptions

Teething can be challenging for some babies, while others may show few signs. A baby teeth chart can help you track the order and timing of each tooth, so you know what’s coming next.

Signs Your Baby Is Teething

Wondering if your baby is teething? Look for these common indicators:

  • Swollen or red gums

  • A strong urge to chew

  • Rubbing their ears

  • Increased fussiness

  • Slightly elevated temperature (not a high fever)

Note: Severe symptoms like high fever or diarrhea are not typical of teething and should be evaluated by a pediatrician.

In What Order Do Baby Teeth Come In?

Teeth usually erupt in a predictable sequence. Here's a general baby teething timeline:

  1. Lower central incisors (bottom front teeth) – around 6–10 months

  2. Upper central incisors – around 8–12 months

  3. Upper and lower lateral incisors – around 9–16 months

  4. First molars – 13–19 months

  5. Canines (cuspids) – 16–23 months

  6. Second molars – 23–33 months

Using a baby teeth eruption chart can help you visualize and track your child’s tooth development.

When Do Baby Molars Come In?

The first molars usually erupt between 12 and 16 months, followed by the second molars between 20 and 30 months. These larger teeth erupt toward the back of the mouth and may cause more discomfort than earlier teeth.

To soothe sore gums, try:

  • Chilled (not frozen) teething rings

  • Cold, damp washcloths

  • Teething-safe toys

  • Dentist-approved teething gels (if needed)

Amber teething necklaces are sometimes used, but their safety is debated—always consult your child’s dentist before using them.

How a Baby Teeth Chart Can Help

A baby teeth chart, also known as a tooth eruption chart, maps out when and where each tooth is expected to appear. This chart can:

  • Help you track tooth development

  • Support timely dental visits

  • Prepare you for the upcoming teething phases

  • Guide early oral care routines

Staying informed can make teething more manageable and ensure your child’s dental health is on the right track.

How Many Baby Teeth Do Kids Get?

By around age 3, most children will have 20 primary teeth:

  • 8 incisors

  • 4 canines

  • 8 molars

These baby teeth—also called milk teeth or deciduous teeth—are essential for chewing, speech development, and holding space for adult teeth.

When Does the First Tooth Appear?

The first tooth usually erupts around 6 months, often one of the lower central incisors. Some babies may get their first tooth as early as 4 months, while others may not until after 12 months.

Once the first tooth appears:

  • Begin brushing with a soft-bristled baby toothbrush

  • Use plain water (no toothpaste unless recommended)

  • Brush twice daily

Early dental care sets the foundation for lifelong oral health.

When Do Babies Get Molars?

To recap molar milestones:

  • First molars: 12–16 months

  • Second molars: 20–30 months

Because molars are larger and emerge farther back in the mouth, they can cause more discomfort. Common signs include chewing, drooling, and restless sleep. Offer safe teething aids and plenty of comfort.

When Do Kids Start Losing Baby Teeth?

Children typically start losing baby teeth around age 6, beginning with the lower central incisors. The process continues gradually, usually finishing by age 12.

This natural shedding of baby teeth makes way for permanent teeth, which are essential for lifelong dental function.

When Do Permanent Teeth Come In?

Permanent teeth begin to appear around age 6:

  • First permanent molars are usually the first to erupt

  • Front baby teeth are replaced by adult teeth next

  • Most children will have 28 permanent teeth by age 12

  • Wisdom teeth (third molars) may come in between ages 17–25

Encouraging strong dental habits early ensures these adult teeth remain healthy into adulthood.

How to Care for Baby Teeth

Good oral hygiene starts with the first tooth. Follow these tips:

  • Brush twice daily with water and a soft brush

  • Schedule the first dental visit by age 1

  • Avoid sugary drinks and prolonged bottle use

  • Never put baby to bed with a bottle

Establishing a routine helps prevent tooth decay and builds healthy habits.

Baby Teeth Timeline Recap

Here’s a quick summary of what to remember about baby teeth:

  • Teething begins around 6 months

  • Lower front teeth are usually the first to erupt

  • Use a baby teeth chart to track tooth development

  • Molars come in later and can cause discomfort
