Teething typically begins around 6 months of age, though it can start as early as 3 months or as late as 12 months.
The Timeline of Teething: When Does It Really Start?
Teething is one of the earliest and most noticeable developmental milestones in an infant’s life. Most parents eagerly—or nervously—await the arrival of that first tooth. But exactly when does this process kick off? The general consensus among pediatricians and dental experts is that teething usually begins around six months of age. However, this is just an average; some babies start teething earlier, as soon as three months, while others may not get their first tooth until after their first birthday.
The variability in timing is perfectly normal and influenced by genetics, nutrition, and overall health. For example, if a parent started teething early, chances are their child might follow a similar pattern. Conversely, late bloomers aren’t unusual either. Teething is a gradual process where teeth erupt through the gums one by one, often starting with the lower central incisors.
Stages Leading Up to Teething
Before teeth break through the gum line, babies go through subtle stages that hint at teething’s arrival. Around 3 to 4 months old, you might notice increased drooling or a desire to chew on anything within reach. This happens because the developing teeth put pressure on the gums, causing discomfort that chewing can temporarily relieve.
Babies may also become fussier or have disturbed sleep patterns during this time. These signs aren’t exclusive to teething but often coincide with it. Understanding these early indicators helps caregivers prepare for what’s ahead.
What Happens During Teething?
The teething process involves more than just the tooth popping out. Inside your baby’s gums, teeth are slowly moving upward—a process called eruption. As they push through soft tissue, inflammation and swelling occur around the gums. This leads to common symptoms such as:
- Gum tenderness and redness
- Increased drooling
- Irritability or fussiness
- A tendency to chew on objects
- Mild changes in eating or sleeping patterns
While these symptoms are typical, severe pain or high fever is not usually caused by teething and should be evaluated by a healthcare professional.
Sequence of Tooth Eruption
Teeth don’t erupt randomly; they follow a specific pattern that most babies experience:
- Lower central incisors (bottom front teeth)
- Upper central incisors (top front teeth)
- Upper lateral incisors (beside front teeth)
- Lower lateral incisors
- First molars (back teeth)
- Canines (pointed teeth beside lateral incisors)
- Second molars (furthest back teeth)
This sequence typically spans from about 6 months to 30 months of age, giving babies a full set of 20 primary teeth by toddlerhood.
The Role Genetics Plays in Teething Age
Genetics plays a surprisingly large role in determining when teething begins. Studies show that children often mirror their parents’ teething timeline. If you were an early teether as a baby, your child might be too. Conversely, delayed eruption can also run in families.
Certain ethnic backgrounds can influence timing slightly due to genetic diversity affecting bone development and growth rates. However, these differences tend to be minor compared to individual variation within any group.
Parents shouldn’t worry if their baby’s timeline doesn’t match another child’s exactly—each infant has their own pace.
A Closer Look at Symptoms: What to Expect When Teeth Arrive
Teething symptoms vary widely between babies but tend to cluster around certain common experiences:
Drooling: Excess saliva production starts weeks before the first tooth appears and can cause skin irritation around the mouth.
Irritability: The discomfort from swollen gums makes some babies restless or cranky.
Mild fever: Slight temperature elevation up to 100.4°F (38°C) may occur but anything above should prompt medical advice.
Coughing or gagging: Drool buildup sometimes triggers coughing fits or gag reflexes.
Chewing on objects: Babies instinctively bite down on toys or fingers to soothe sore gums.
While these signs are typical during teething phases, severe symptoms like diarrhea or high fever likely stem from other causes.
Pain Management Strategies for Teething Babies
Parents often seek safe ways to ease their baby’s discomfort during this challenging period. Here are some effective remedies:
- Cold objects: Chilled (not frozen) teething rings or wet washcloths provide soothing relief when chewed on.
- Mild gum massage: Gently rubbing your finger over swollen gums can reduce pain temporarily.
- Pain relievers: Infant acetaminophen or ibuprofen may be recommended by pediatricians for severe fussiness but should be used cautiously.
- Avoid numbing gels: Over-the-counter gels containing benzocaine aren’t advised for infants due to safety concerns.
Always consult your pediatrician before administering medications.
The Complete Baby Teeth Eruption Chart
Below is a detailed chart showing average ages for each primary tooth eruption stage:
Tooth Type | Eruption Age Range (Months) | Description |
---|---|---|
Lower Central Incisors | 6 – 10 | The very first two bottom front teeth; usually appear first. |
Upper Central Incisors | 8 – 12 | The top front middle two teeth; follow shortly after lower incisors. |
Lateral Incisors (Upper & Lower) | 9 – 16 | The teeth adjacent to central incisors; appear soon after front center teeth. |
First Molars (Upper & Lower) | 13 – 19 | Larger back teeth used for grinding food; erupt after incisors. |
