The first teeth typically emerge between 4 and 7 months of age, marking a key milestone in infant development.
The Timeline of Baby’s First Teeth
The arrival of a baby’s first teeth is an exciting and often eagerly anticipated event for parents. While the timing can vary widely, most infants begin teething around the age of 4 to 7 months. This process is called “eruption,” where teeth break through the gums and become visible.
Typically, the lower central incisors—the two bottom front teeth—are the first to appear. These are followed closely by the upper central incisors, then the lateral incisors on both the top and bottom jaws. By around age three, most children will have a full set of 20 primary teeth, commonly known as baby or deciduous teeth.
It’s important to note that every baby develops at their own pace. Some children might get their first tooth as early as 3 months, while others may not see any until after their first birthday. Neither extreme is usually cause for concern unless accompanied by other developmental delays or health issues.
Factors Influencing When Teeth Appear
Several factors influence when the first teeth come in:
- Genetics: Family history plays a big role. If parents or siblings had early or late teething, chances are similar for the baby.
- Nutrition: Adequate intake of calcium, vitamin D, and phosphorus supports healthy tooth development.
- Prematurity: Premature babies often experience delayed tooth eruption compared to full-term infants.
- Health conditions: Certain medical conditions or syndromes can affect dental development and timing.
Understanding these factors helps parents set realistic expectations and recognize when professional advice might be needed.
Signs That Indicate Teeth Are Coming In
Before those pearly whites break through the gum line, babies often display clear signs that teething is underway. Recognizing these symptoms can help caregivers provide comfort during this sometimes uncomfortable phase.
Common signs include:
- Increased drooling: Teething stimulates saliva production, leading to dribbling that can cause skin irritation around the mouth.
- Irritability and fussiness: The pressure from erupting teeth can cause discomfort or mild pain.
- Chewing on objects: Babies instinctively gnaw on toys, fingers, or other items to relieve gum pressure.
- Slight swelling or redness of gums: The area where a tooth is about to emerge may appear swollen or tender.
- Mild changes in eating or sleeping patterns: Discomfort might make feeding more challenging or disrupt sleep temporarily.
However, it’s important to distinguish normal teething symptoms from signs of illness. High fever, diarrhea, or severe irritability should prompt a visit to a healthcare provider as they’re not typical teething symptoms.
The Myth of High Fever and Teething
A common misconception is that teething causes high fever in babies. While mild temperature elevation (around 99–100°F) can occur due to inflammation in gums, significant fevers (above 101°F) are usually unrelated to teething.
If your baby develops a high fever alongside other symptoms like lethargy or rash during teething age, seek medical evaluation promptly. This ensures infections or other illnesses aren’t overlooked.
The Order and Pattern of Tooth Eruption
Knowing which teeth come in first helps parents track progress and anticipate what’s next in their child’s dental journey. The eruption sequence tends to follow a fairly predictable pattern:
| Teeth Type | Eruption Age Range (Months) | Description |
|---|---|---|
| Lower Central Incisors | 4 – 7 | The very first two bottom front teeth; usually earliest to appear. |
| Upper Central Incisors | 8 – 12 | The two top front teeth follow shortly after lower incisors. |
| Lateral Incisors (Upper & Lower) | 9 – 13 | The small teeth adjacent to central incisors; come next in line. |
| First Molars (Upper & Lower) | 13 – 19 | Larger chewing teeth appearing behind incisors; important for grinding food. |
| Canines (Cuspids) | 16 – 23 | The pointed “fang-like” teeth beside lateral incisors; key for tearing food. |
| Second Molars (Upper & Lower) | 23 – 33 | The last set of baby molars; complete primary dentition by about age three. |
This timeline is an average guide rather than a strict rulebook. Some babies may have slight variations without any issues.
The Role of Primary Teeth in Development
Primary teeth aren’t just placeholders for adult teeth—they’re vital for several reasons:
- Aiding chewing and nutrition: Proper chewing helps digestion and ensures good nutrition during critical growth phases.
- Aiding speech development: Teeth help form sounds correctly as babies start babbling into words.
- Keeps space for permanent teeth: Baby teeth hold space in the jawbone so adult teeth grow in properly aligned later on.
- Affects facial structure: Healthy primary teeth contribute to proper jaw development and facial aesthetics.
Neglecting baby teeth health can lead to cavities and infections that impact overall oral health down the road.
Caring for Baby Teeth From Day One
Oral care starts even before those first pearly whites peek through! Cleaning your baby’s gums regularly with a soft cloth after feeding helps remove bacteria buildup.
Once the first tooth erupts:
- Select an appropriate toothbrush: Use a small-headed toothbrush with soft bristles designed specifically for infants.
- Avoid toothpaste with fluoride until recommended age: For babies under two years old, use only a smear (about grain-sized) amount of fluoride toothpaste if advised by your dentist or pediatrician.
- Create gentle brushing habits: Brush twice daily using gentle circular motions focusing on all surfaces of emerging teeth and gums.
Establishing good oral hygiene routines early sets up lifelong habits that protect against cavities and gum disease.
Troubleshooting Common Teething Challenges
Teething isn’t always smooth sailing—some babies experience more discomfort than others which can be tough on both infant and caregiver alike.
Here are some tips addressing common challenges:
- Drooling rash: Constant wetness may irritate cheeks/chins—apply barrier creams like petroleum jelly regularly after wiping drool away gently with soft cloths.
- Pain relief strategies: Offer chilled (not frozen) teething rings or clean cold washcloths for chewing relief; avoid numbing gels unless prescribed due to safety concerns with overuse.
- Irritability management: Extra cuddling, distraction with toys/books/music can soothe cranky moods linked to gum soreness.
If symptoms worsen significantly—high fever, refusal to eat/drink persistently—consult your pediatrician promptly.
The Big Question: When Do The First Teeth Come In?
The exact moment varies but expect those little chompers anytime between four months up through one year old. Most commonly though, you’ll see those bottom front incisors pop through between four to seven months. Tracking this milestone helps monitor overall growth but don’t panic if your baby’s timeline is slightly offbeat—it’s perfectly normal!
Keeping tabs on eruption patterns along with maintaining good oral care routines ensures your child’s smile starts strong from day one. Remember: healthy baby teeth pave way for healthy permanent ones later on.

Frequently Asked Questions
When do the first teeth come in for most babies?
The first teeth typically come in between 4 and 7 months of age. This milestone marks the eruption of the lower central incisors, which are usually the first to break through the gums. However, timing can vary widely from baby to baby.
When do the first teeth come in for premature babies?
Premature babies often experience delayed tooth eruption compared to full-term infants. While full-term babies usually start teething around 4 to 7 months, premature infants may get their first teeth later due to differences in overall development.
When do the first teeth come in if there is a family history of early teething?
Genetics plays a significant role in when the first teeth come in. If parents or siblings had early teething, it’s likely that a baby may also experience earlier tooth eruption, sometimes as early as 3 months of age.
When do the first teeth come in and what are common signs before they appear?
Before the first teeth come in, babies often show signs like increased drooling, irritability, chewing on objects, and slight gum swelling. These symptoms usually begin shortly before the lower front teeth emerge between 4 and 7 months.
When do the first teeth come in and how many primary teeth does a child have by age three?
The first teeth generally appear between 4 and 7 months. By around age three, most children have a full set of 20 primary or baby teeth. These include incisors, canines, and molars that develop over time following initial eruption.
Conclusion – When Do The First Teeth Come In?
When do the first teeth come in? Usually between four and seven months old—the lower central incisors lead the way followed by upper front ones soon after. This process signals an important developmental phase involving changes not only in appearance but also feeding habits and comfort levels.
Understanding typical timelines alongside signs of teething equips parents with knowledge needed to support their little ones effectively. With proper care—from gentle cleaning routines to nutritional support—babies get off on the right foot toward lifelong oral health.
