Teething is a major milestone in your baby’s development.
It marks the arrival of their first set of teeth, which play a key role in chewing, speaking, and guiding future adult teeth.
While every baby is different, most follow a fairly typical teething timeline. Let’s walk through it together 👣
🗓️ Teething Timeline: When Do Baby Teeth Erupt?
🍼 0–3 Months: Pre-Teething Stage
Babies are born with all 20 primary teeth hidden beneath the gums.
You might notice more drooling and oral exploration as saliva production increases.
👶 4–6 Months: First Teeth Appear
The lower central incisors (bottom front teeth) are usually the first to arrive.
You may notice fussiness, gum swelling, or a strong desire to chew.
🧊 Tip: Offer a cold teething toy or washcloth for comfort.
😁 7–12 Months: More Front Teeth
- Upper central incisors (top front) come in around 8–10 months
- Lateral incisors (next to the central ones) follow between 9–12 months
Disrupted sleep and irritability are common during this time.
🍽️ 12–18 Months: First Molars & Canines
- First molars (back teeth) erupt between 12–16 months
- Canines (pointy side teeth) arrive around 16–18 months
These can cause more discomfort due to their size — chilled teethers help!
👧 18–24 Months: Second Molars Erupt
These are the last baby teeth to come in, usually by 24 months.
This stage can be more painful — but it signals the end of the teething journey!
🦷 By Age 3: Full Set of 20 Teeth
Most children will have all 20 baby teeth by age 3. These teeth set the stage for healthy development and proper alignment of permanent teeth.
😣 Common Signs & Symptoms of Teething
Not all babies experience teething the same way.
Here are common symptoms to look out for:
- Excessive drooling
- Irritability or fussiness
- Swollen, tender gums
- Sleep disturbances
- Loss of appetite
- Biting and chewing on objects
- Mild fever (below 100.4°F or 38°C)
❗ Note: High fever or diarrhea is not typical of teething. Always check with a pediatrician if you’re unsure.
🧊 How to Soothe Teething Discomfort
Here are simple ways to help your little one feel better:
- Teething toys – BPA-free and soft toys are great for gnawing
- Cold washcloth – Chilling a damp cloth can soothe swollen gums
- Gum massage – Use a clean finger to apply gentle pressure
- Distraction – Singing, reading, or cuddling can calm their mind
- Pain relief (if needed) – Ask your pediatrician about infant-safe meds
🪥 Caring for Your Baby’s Teeth
Start early! Good oral care begins with the first tooth:
- Clean gums with a soft cloth before teeth come in
- Use a rice-sized amount of fluoride toothpaste when brushing
- Avoid sugary drinks and juice in bottles
- Schedule a first dental visit by age 1
🦷 When to See a Pediatric Dentist
Reach out to a pediatric dentist if:
- No teeth have come in by 12 months
- Baby teeth look discolored or misshapen
- Teething pain seems excessive or unmanageable
- Teeth come in an unusual order or position
❓ Frequently Asked Questions
1. How long does teething last?
Teething usually spans from 4–6 months to about 3 years of age.
2. Does teething cause high fever?
No — a mild fever is okay, but anything over 100.4°F is not typical.
3. Teething or just fussiness?
Look for classic signs like chewing, swollen gums, and extra drool.
4. Why is my baby drooling so much?
It’s completely normal! Use bibs to prevent skin irritation under the chin.
5. My baby won’t eat — is that normal?
Yes. Try cold, soft foods like yogurt or applesauce to ease gum pain.
6. When should I start brushing?
Start brushing as soon as the first tooth erupts with a soft baby toothbrush.
7. Can teething cause diarrhea?
No direct link. Contact your doctor if diarrhea persists.
8. Are teething gels safe?
Avoid benzocaine-based gels. Always check with your pediatrician first.
9. Teeth coming in crooked — should I worry?
Not right away. Baby teeth often straighten as more teeth arrive.
10. When should the first dental visit happen?
By your child’s first birthday — or within 6 months of the first tooth.
