Kids develop two sets of molars: primary (baby) molars and permanent molars, each playing a vital role in chewing and dental health.
The Role of Molars in Children’s Oral Development
Molars are the large, flat teeth located at the back of the mouth. They’re essential for grinding and chewing food effectively. Kids don’t just get one set of molars; they actually develop two distinct sets over time. The first set is called primary or baby molars, which help little ones chew their food properly while their jaws grow. Later on, these baby molars make way for permanent molars, which serve as the adult chewing powerhouse.
Understanding exactly what molars kids get and when they appear helps parents keep track of their child’s dental development. It also aids in recognizing any potential issues early on. These teeth aren’t just placeholders—they guide the alignment of other permanent teeth and maintain the structure of the jaw.
Primary Molars: The First Chewing Champions
Primary molars are part of a child’s first set of teeth, commonly known as baby teeth. These molars usually erupt between ages 12 to 28 months, following the emergence of front teeth like incisors and canines. They’re smaller than permanent molars but have broad surfaces perfect for grinding soft foods.
There are typically eight primary molars in total—four on the top jaw and four on the bottom. These teeth play a crucial role in speech development, proper chewing, and maintaining space for permanent teeth underneath.
Primary molars eventually loosen and fall out as children grow, making room for permanent premolars (which replace baby molars) and permanent molars that erupt behind them.
Timeline for Primary Molar Eruption
The eruption schedule for primary molars can vary slightly but generally follows this pattern:
- First Primary Molars: Appear around 12-16 months.
- Second Primary Molars: Come in around 20-28 months.
These milestones are important markers in your child’s oral health journey. Delays or early eruption might warrant a checkup with a pediatric dentist to ensure everything is progressing normally.
Permanent Molars: The Adult Chewers Arrive
Once kids reach about six years old, their permanent molars start to emerge. These are different from baby molars because they don’t replace any existing teeth—they come in behind them. The first permanent molar is often called the “six-year molar” since it usually erupts around that age.
Permanent molars are larger, stronger, and have more pronounced cusps to handle tougher foods as children grow into adults. Their roots are longer and more complex too, anchoring them firmly into the jawbone.
There are three sets of permanent molars that develop over time:
- First Molars: Around age 6.
- Second Molars: Around age 12.
- Third Molars (Wisdom Teeth): Late teens to early twenties (sometimes absent).
These permanent molars play a critical role in maintaining proper bite alignment and overall oral function throughout life.
The Importance of First Permanent Molars
The first permanent molar is sometimes overlooked because it doesn’t replace any baby tooth—it erupts behind them. However, this tooth is crucial because it helps establish the bite pattern and holds space for other adult teeth to come in properly.
If these first permanent molars suffer decay or damage early on, it can lead to bite problems or crowding later. That’s why dentists emphasize protecting these teeth with sealants or fluoride treatments once they erupt.
The Difference Between Baby Molars and Permanent Molars
It’s easy to confuse baby molars with their adult counterparts since both occupy similar positions in the mouth at different times. Here’s how they differ:
| Feature | Primary (Baby) Molars | Permanent Molars |
|---|---|---|
| Number per quadrant | 2 (first & second) | 3 (first, second & third/wisdom) |
| Eruption Age | 12-28 months | 6 years to early twenties |
| Size & Shape | Smaller & less complex cusps | Larger with more pronounced cusps & roots |
| Lifespan | Shed around ages 10-12 | Permanently retained if healthy |
| Purpose | Aid chewing; hold space for adult teeth | Main chewing function; support facial structure |
This table highlights why both types matter but serve distinct roles during different stages of childhood development.

Frequently Asked Questions
What molars do kids get first?
Kids first get primary molars, also known as baby molars. These typically erupt between 12 to 28 months of age and help children chew soft foods while their jaws grow. Primary molars play an important role in speech development and maintaining space for permanent teeth.
When do permanent molars appear in kids?
Permanent molars usually begin to emerge around age six. Unlike baby molars, these adult molars do not replace any existing teeth but come in behind them to provide stronger chewing power for older children.
How many molars do kids get in total?
Children develop two sets of molars: eight primary molars (four on the top and four on the bottom) and up to twelve permanent molars, including first, second, and sometimes third molars that appear later in childhood or adolescence.
What is the role of molars kids get in dental health?
The molars kids get are essential for grinding food properly and supporting jaw development. Primary molars maintain space for permanent teeth, while permanent molars provide long-lasting chewing strength and help guide the alignment of other teeth.
Why do kids lose the primary molars they get?
Kids lose their primary molars because these baby teeth make room for permanent premolars and permanent molars. The shedding of primary molars allows the adult teeth to emerge properly and maintain healthy dental structure as the child grows.
Caring for Your Child’s Molars: Tips & Tricks
Molars have grooves and pits that trap food easily—making them prone to cavities if not cleaned properly. Since these back teeth play such an essential role in chewing and alignment, keeping them healthy is paramount.
- Create a Brushing Routine: Help your child brush twice daily focusing on all tooth surfaces including those hard-to-reach back molars.
- Use Fluoride Toothpaste: Fluoride strengthens enamel and helps prevent decay especially on vulnerable surfaces like those on molar teeth.
- Dentist Visits Matter: Regular checkups allow dentists to monitor eruption patterns, apply sealants on new permanent molars, and catch cavities early.
- Avoid Sugary Snacks: Frequent sugar intake increases cavity risk particularly on sticky surfaces found on molar grooves.
- Crowns & Sealants: For kids prone to cavities or deep fissures on their molar surfaces, dental professionals recommend protective coatings known as sealants or crowns.
- Mouthguards During Sports: Protect those strong but vulnerable back teeth during active play by using custom-fitted mouthguards.
- Around 12-16 Months: First primary (baby) molar erupts.
- Around 20-28 Months: Second primary (baby) molar comes through completing baby set.
- Around Age 6: First permanent (adult) molar erupts behind baby teeth without replacing any tooth.
- Around Age 10-12: Primary (baby) second molar sheds making way for premolars.
- Around Age 11-13: Second permanent (adult) molar erupts behind first adult ones.
- Around Late Teens-Early Twenties: Third permanent molares (wisdom teeth) may appear or remain absent depending on genetics.
- Painful abscesses requiring root canals or extractions;
- Crowding caused by premature tooth loss;
- Bite misalignments impacting speech and eating;
- Difficulties with jaw growth due to missing support from key back teeth;
- Poor oral hygiene habits carrying into adulthood affecting overall health;
These steps make a huge difference in preserving your kid’s smile now—and down the road.

This timeline shows how dynamic children’s mouths truly are during growth years—and why regular dental visits matter so much during this period.
The Wisdom Teeth Factor: Optional Players?
Not every child develops wisdom teeth—the third set of permanent molars that typically show up between ages 17-25. Some people never get them at all due to evolutionary changes reducing jaw size over generations.
When wisdom teeth do erupt, they often cause crowding or impaction issues requiring removal by oral surgeons. For kids who don’t get wisdom teeth at all, it simply means fewer back teeth but no loss in chewing efficiency if other adult molars are healthy.
The Connection Between Baby Molars and Permanent Teeth Alignment
Baby molars aren’t just temporary placeholders; they act like guides for incoming adult teeth. Losing baby molars prematurely due to decay or trauma can cause neighboring teeth to shift into empty spaces—leading to crowding or misalignment later when adult premolars try to emerge.
Orthodontists often stress preserving baby molar health until natural shedding occurs because these little giants help maintain proper spacing within developing jaws. In cases where baby molar loss happens too soon, space maintainers might be used—a small dental appliance that holds open room until adult teeth arrive.
This connection underlines why knowing what molars do kids get—and caring for each stage—is crucial beyond just simple chewing function.
The Impact of Early Dental Problems on Molar Development
Unchecked cavities or infections affecting either primary or permanent molar development can lead to long-term complications like:
Thankfully modern dentistry offers many solutions such as fluoride treatments, sealants, fillings designed specifically for children’s smaller tooth anatomy, plus education aimed at preventing decay before it starts.
Parents should keep an eye out for signs like sensitivity around back teeth during meals or visible discoloration—promptly consulting dentists ensures timely intervention before problems snowball out of control.
Crowding And Orthodontics: How Molars Influence Smiles Later On
Permanent first and second molar positions heavily influence how other adult teeth arrange themselves within the mouth. If these foundational back teeth erupt improperly angled or decayed too early causing loss—orthodontic issues become more likely down the road.
Braces often rely on stable anchoring points provided by healthy first permanent molar roots during treatment phases designed to straighten front incisors or correct bite irregularities. Missing or damaged adult molar roots complicate orthodontic plans significantly.
That said, early monitoring by dentists combined with good home care can minimize risks related to improper eruption sequences or premature tooth loss—helping kids grow up with strong foundations supporting confident smiles later on.
Conclusion – What Molars Do Kids Get?
Kids go through two main phases when it comes to their back chewing champions: first getting primary (baby) molars between one and two years old followed by multiple sets of larger permanent ones starting around age six through early adulthood. Each type plays an irreplaceable role—from helping toddlers chew soft foods safely while preserving space for future adult premolars—to establishing lifelong bite patterns through strong permanent first and second adult molar emergence.
Paying close attention to what molars do kids get means understanding timing differences between baby versus adult sets plus knowing how vital proper care is at every stage—from brushing routines targeting tricky grooves all the way up to professional sealants safeguarding newly erupted six-year-old permanents.
Healthy development of these powerful grinding tools supports not only effective eating but also jaw growth stability plus orthodontic success later down the line—making every parent appreciate just how important these often overlooked back teeth really are!
