Infants typically begin to grow teeth between 4 and 7 months of age, with the lower central incisors usually appearing first.
The Timeline of Infant Teething: What to Expect
Teething is a major milestone in an infant’s early development. Most babies start growing their first teeth somewhere between 4 and 7 months, though this can vary widely. The process generally begins with the eruption of the lower central incisors, those two little teeth right in the middle of the bottom gum line. These are followed by upper central incisors, lateral incisors, first molars, canines, and finally second molars.
It’s important to remember that every baby is unique. Some infants may show their first tooth as early as 3 months, while others may not get any until after their first birthday. Both ends of this spectrum can be perfectly normal.
Parents often wonder exactly when do infants grow teeth and what signs to watch for. Teething isn’t just about the appearance of teeth; it’s a process involving gums swelling, discomfort, and sometimes fussiness. This period can last several months as each tooth gradually breaks through the gum surface.
Typical Order of Tooth Eruption
The general sequence in which infants grow their primary (baby) teeth tends to follow a predictable pattern:
- Lower central incisors: Usually the first to appear around 6 months.
- Upper central incisors: Follow shortly after, around 8 months.
- Lateral incisors: Both upper and lower come next, approximately at 9-12 months.
- First molars: Appear around 13-19 months.
- Canines (cuspids): Surface between 16-23 months.
- Second molars: Usually arrive last at about 20-33 months.
This order helps dentists and pediatricians track dental development and spot any delays or abnormalities early on.
Signs and Symptoms Accompanying Infant Teething
When do infants grow teeth? They often give clues before the actual tooth pokes through the gums. Parents might notice increased drooling, chewing on objects or fingers, irritability, swollen or tender gums, and disrupted sleep patterns.
Some babies become fussier or clingier during teething periods due to discomfort. The gums may appear redder or puffier than usual as teeth push upward through the soft tissue.
While mild fever (below 101°F) occasionally occurs during teething phases, high fever or severe symptoms should prompt medical evaluation since they’re unlikely caused by teething alone.
Babies may also refuse food or have a decreased appetite temporarily because chewing hurts sensitive gums. Offering chilled teething rings or gentle gum massages can provide relief.
Common Teething Remedies Parents Use
To ease discomfort during this milestone:
- Teething rings: Chilled (not frozen) rings offer soothing pressure on gums.
- Cold washcloths: Soft cloths cooled in the refrigerator provide gentle relief.
- Mild gum massage: Using clean fingers to rub gums reduces pain.
- Pain relievers: Pediatrician-approved doses of acetaminophen or ibuprofen may be recommended for severe fussiness.
Avoid teething tablets containing potentially harmful substances like benzocaine unless explicitly advised by a healthcare provider.
The Science Behind Tooth Development in Infants
Teeth formation begins long before birth—around six weeks into pregnancy when tooth buds develop beneath the gums. These buds gradually mineralize into enamel and dentin layers that make up a tooth’s structure.
After birth, these buds wait below the gum surface until conditions trigger eruption. The process involves resorption of bone above the developing tooth crown so it can push upward through soft tissues.
Growth factors and genetics heavily influence timing. Some infants inherit genes that speed up eruption; others have slower progression but still develop healthy teeth.
Nutritional status also plays a role. Adequate intake of calcium, phosphorus, vitamin D, and other minerals supports proper enamel formation and eruption timing.
The Complete Baby Teeth Eruption Chart
Tracking when do infants grow teeth gets easier with a clear chart showing average eruption ages for each primary tooth type. Here’s a detailed breakdown:
| Tooth Type | Eruption Age Range (Months) | Description |
|---|---|---|
| Lower Central Incisors | 4 – 7 | The very first baby teeth to appear; bottom front center teeth. |
| Upper Central Incisors | 8 – 12 | The top front center teeth following shortly after lower ones. |
| Lateral Incisors (Upper & Lower) | 9 – 16 | Sides next to central incisors; help with biting food. |
| First Molars (Upper & Lower) | 13 – 19 | Larger back teeth important for chewing solid foods. |
| Canines (Cuspids) | 16 – 23 | The pointed “eye” teeth that aid tearing food. |
| Second Molars (Upper & Lower) | 20 – 33 | The last baby teeth to erupt; crucial for grinding food efficiently. |
This timeline serves as a helpful guide but remember natural variation is wide-ranging among healthy infants.
The Impact of Early vs Late Teething on Infant Health
Early teething—say before four months—is generally harmless but sometimes causes concern among parents who worry about abnormal development. In most cases, early eruption doesn’t signal underlying problems but may require extra attention for choking hazards since babies might mouth everything more aggressively.
Late teething—beyond one year without any erupted primary teeth—is less common but usually not alarming either if growth otherwise appears normal. Pediatric dentists recommend evaluation if no primary teeth appear by age one since it could indicate conditions like:
- Agenesis (missing tooth buds)
- Nutritional deficiencies affecting mineralization
- Certain genetic syndromes impacting dental development
Early intervention ensures proper oral health care planning including guidance on oral hygiene once teeth emerge.
Caring for Baby Teeth Once They Appear
Once those tiny pearly whites break through gums, establishing good dental habits is key:
- Bristle toothbrushes: Use soft infant toothbrushes with water only initially to clean newly erupted teeth gently twice daily.
- Avoid sugar exposure: Limit sugary drinks and prolonged bottle feeding especially at bedtime to prevent early decay known as “baby bottle tooth decay.”
- Pediatric dental visits: Schedule first dentist appointment by age one or within six months after first tooth erupts for professional guidance and monitoring.
Healthy baby teeth set foundation for proper chewing development, speech skills, and eventual adult dentition alignment.
Tackling Common Misconceptions About When Do Infants Grow Teeth?
Several myths surround infant teething timing that confuse caregivers:
- “All babies start teething at six months”: This isn’t true; some start earlier or later without issue.
- “Teething causes high fever”:
- “Babies must be fed solids once they start teething”:
Separating fact from fiction helps parents respond appropriately during this sometimes stressful phase without unnecessary worry.
The Role of Pediatricians and Dentists in Monitoring Tooth Growth
Healthcare providers play critical roles ensuring infant oral health milestones are met timely:
- Pediatricians routinely check mouth development during well-baby visits noting signs of emerging teeth or delays.
- Pediatric dentists specialize in early childhood oral care offering advice on hygiene techniques tailored for infants plus preventive strategies against cavities starting from tooth eruption onward.
Open communication between parents and professionals about any concerns related to when do infants grow teeth fosters better outcomes through prompt support or treatment if needed.

Frequently Asked Questions
When Do Infants Grow Teeth for the First Time?
Infants typically begin to grow teeth between 4 and 7 months of age. The first teeth to appear are usually the lower central incisors, those two little teeth in the middle of the bottom gum line.
When Do Infants Grow Teeth Beyond the First Set?
After the initial lower central incisors, infants grow upper central incisors around 8 months, followed by lateral incisors between 9 and 12 months. First molars usually arrive between 13 and 19 months, continuing the teething process.
When Do Infants Grow Teeth if They Appear Early or Late?
While most infants start teething between 4 and 7 months, some may show their first tooth as early as 3 months or as late as after their first birthday. Both early and late teething can be perfectly normal.
When Do Infants Grow Teeth and What Signs Indicate It?
Before teeth appear, infants often show signs like increased drooling, chewing on objects, irritability, and swollen gums. These symptoms usually begin shortly before teeth start breaking through the gums.
When Do Infants Grow Teeth in the Typical Order of Eruption?
The typical order starts with lower central incisors around 6 months, then upper central incisors at about 8 months. This is followed by lateral incisors, first molars, canines, and second molars over the next two years.
Conclusion – When Do Infants Grow Teeth?
Infant tooth growth typically begins around four to seven months with wide normal variation influenced by genetics and nutrition.
