Kids typically have 20 primary teeth, which begin to emerge around six months and are later replaced by 32 permanent teeth.
The Complete Breakdown of Kids’ Teeth
Understanding how many teeth kids have involves knowing about two distinct sets: primary (baby) teeth and permanent (adult) teeth. Kids are born without visible teeth, but beneath the gums, the process of tooth development starts quite early during infancy. The first set of teeth, known as primary or deciduous teeth, usually begins to erupt around six months of age. This set consists of exactly 20 teeth, which serve essential roles in chewing, speaking, and maintaining space for the permanent teeth waiting in the jaw.
These 20 primary teeth include incisors, canines, and molars. They’re smaller and whiter than adult teeth but just as critical for a child’s oral health. The primary teeth typically finish erupting by the age of three. These baby teeth don’t last forever; they start to fall out around age six to make room for permanent adult teeth. In total, adults have 32 permanent teeth, including wisdom teeth that usually appear between ages 17 and 25.
Primary Teeth Types and Their Numbers
The 20 baby teeth are divided into four types based on their function and location in the mouth:
- Incisors (8 total): These are the front cutting teeth—four on top and four on bottom.
- Canines (4 total): Positioned next to incisors; they’re pointed for tearing food.
- Molars (8 total): Located at the back; these flat-topped teeth grind food.
No premolars exist in this first set—they only appear in the permanent dentition.
The Timeline: When Do Kids Get Their Teeth?
The eruption schedule for baby teeth follows a fairly predictable pattern but can vary between children. Most infants get their first tooth around six months, often one of the lower central incisors. From there, new teeth continue emerging roughly every few weeks or months until all 20 appear by age three.
Here’s a general timeline:
- 6-10 months: Lower central incisors erupt.
- 8-12 months: Upper central incisors come in.
- 9-16 months: Lateral incisors (next to centrals) emerge.
- 16-23 months: First molars start to appear.
- 17-23 months: Canines arrive next.
- 23-33 months: Second molars complete the set.
This sequence ensures kids develop a full set of functional baby teeth before transitioning to permanent ones.
The Role of Primary Teeth Beyond Chewing
Primary teeth do much more than just help kids chew food. They act as placeholders for adult teeth, guiding them into proper alignment as they grow. Losing baby teeth prematurely can cause crowding or misalignment issues later on.
Moreover, these early teeth contribute heavily to speech development. Without them, children may struggle with pronouncing certain sounds correctly—a factor often overlooked by parents.
The Transition: Losing Baby Teeth and Gaining Permanent Ones
The journey from baby to adult teeth is gradual but fascinating. Starting around age six or seven, children begin shedding their primary molars and incisors. This process continues until about age twelve or thirteen when most baby teeth have been replaced.
Permanent dentition includes:
- Total Teeth: Usually 32 (including wisdom teeth)
- Types: Incisors, canines, premolars (new addition), molars
Unlike baby teeth, permanent ones have deeper roots and a more complex structure designed for lifelong use.
A Closer Look at Permanent Teeth Types
Permanent sets introduce premolars—teeth that don’t exist in baby sets—to help with chewing tougher foods. Here’s a breakdown:
| Type of Tooth | Number per Set | Main Function |
|---|---|---|
| Incisors | 8 (4 top + 4 bottom) | Cuts food into smaller pieces |
| Canines | 4 (2 top + 2 bottom) | Tears food apart |
| Premolars (Bicuspids) | 8 (4 top + 4 bottom) | Tears and crushes food |
| Molars (Including Wisdom Teeth) | 12 (6 top + 6 bottom) | Grinds food thoroughly for digestion |
Not every child develops wisdom teeth; some never get them or have fewer than four.
Caring for Baby Teeth: Why It Matters So Much
Even though baby teeth eventually fall out, they deserve serious care from day one. Cavities in primary dentition can cause pain and affect eating habits or speech development. More importantly, infections can spread to developing adult tooth buds underneath.
Parents should start cleaning their infant’s gums early with a soft cloth even before any tooth erupts. Once those pearly whites show up, brushing twice daily with a small amount of fluoride toothpaste is essential.
Regular dental check-ups should begin no later than the child’s first birthday or within six months after the first tooth appears. Early visits help spot problems early and instill good oral hygiene habits.
The Impact of Diet on Kids’ Dental Health
Sugary snacks and drinks are notorious culprits behind cavities in kids’ mouths. Frequent exposure fuels bacteria that produce acids eroding enamel—the protective outer layer of both baby and adult teeth.
Limiting sugary treats while encouraging water consumption helps maintain strong enamel. Crunchy fruits and vegetables also aid saliva production—a natural defense against decay-causing bacteria.
The Variability: When Does Tooth Eruption Differ?
While there’s a standard timeline for tooth eruption, some kids experience variations that are perfectly normal. Some may get their first tooth as early as three months; others might wait until after their first birthday.
Similarly, losing baby teeth earlier or later than peers doesn’t always signal trouble unless accompanied by pain or other symptoms like swelling or fever.
Genetics play a big role here—parents who had late eruptions often see similar patterns in their children.
The Signs That Warrant Professional Attention
Certain signs mean it’s time to see a pediatric dentist sooner rather than later:
- No tooth eruption by age one without obvious reasons.
- Persistent pain or discomfort during teething beyond typical irritability.
- Lopsided eruption pattern where many upper or lower front teeth fail to appear on schedule.
- Evident decay spots or white patches on visible baby teeth indicating early cavities.
Professional exams ensure any issues get addressed promptly before worsening.
The Final Count: How Many Teeth Do Kids Have?
To wrap it up neatly: kids generally have 20 primary (baby) teeth that erupt between about six months and three years old. These serve vital functions until they’re replaced between ages six and twelve by 32 permanent adult teeth—including incisors, canines, premolars, molars, and sometimes wisdom teeth later on.
This natural progression supports healthy chewing habits, clear speech development, facial structure growth, and proper alignment for lifelong oral health.
Parents who understand this dental timeline can better support their children through each stage with appropriate care routines and timely dental visits—setting them up for smiles that last a lifetime!

Frequently Asked Questions
How Many Teeth Do Kids Have When They Are Babies?
Kids typically have 20 primary teeth, also called baby teeth, which begin to emerge around six months of age. These teeth usually finish erupting by the time a child is about three years old.
How Many Teeth Do Kids Have Before Losing Their Baby Teeth?
Before losing their baby teeth, kids have a full set of 20 primary teeth. These include incisors, canines, and molars that help with chewing and speaking until permanent teeth start to come in around age six.
How Many Teeth Do Kids Eventually Get as Adults?
While kids start with 20 baby teeth, they eventually develop 32 permanent adult teeth. This includes wisdom teeth, which usually appear between the ages of 17 and 25, replacing the primary set over time.
How Many Types of Teeth Do Kids Have in Their Primary Set?
The 20 baby teeth kids have are divided into three types: 8 incisors for cutting, 4 canines for tearing food, and 8 molars for grinding. Premolars do not appear until the permanent teeth come in later.
How Many Teeth Do Kids Have When They First Start Teething?
Kids are born without visible teeth but begin teething around six months old. The first teeth to appear are usually the lower central incisors, starting the process that will lead to a full set of 20 primary teeth.
Conclusion – How Many Teeth Do Kids Have?
Knowing how many teeth do kids have reveals much more than just numbers—it opens a window into crucial developmental milestones packed with growth challenges and triumphs. Twenty tiny but mighty primary pearly whites pave the way for an eventual full set of thirty-two durable adult chompers designed to last decades when cared for properly.
From infancy through adolescence, monitoring this transition helps catch potential problems early while fostering habits that preserve dental health well beyond childhood years. So next time you wonder about your little one’s smile count—remember those precious twenty hold incredible importance far beyond just chewing!
