When Do Babies Start Teething?
Most babies start teething around 6 months, though some begin as early as 3 months or as late as 12 months. You’ll notice increased drooling, irritability, and a desire to chew on objects when teeth are emerging. The first teeth to appear are typically the lower central incisors, followed by the upper central incisors. If your baby has a fever above 38°C or excessive crying, consult your pediatrician. The complete teething journey continues through age 3.
Key Takeaways
- Most babies begin teething around 6 months of age when their first tooth typically emerges.
- Some babies may start showing teething signs as early as 3 months of age.
- Lower central incisors (bottom front teeth) are usually the first to appear between 6-10 months.
- Upper central incisors (top front teeth) typically emerge between 8-12 months.
- Early teething signs include increased drooling, swollen gums, chewing on objects, fussiness, and sleep disturbances.
The First Signs Your Baby Is Teething
You may be interested
When your baby begins teething, you’ll likely notice several distinctive changes in their behavior and physical appearance. The most common teething symptoms include increased drooling (often causing facial rashes), swollen or tender gums where teeth are emerging, and a strong desire to chew on hard objects.
You may observe your baby:
- Becoming fussier than usual
- Rubbing their cheeks or ears
- Experiencing mild sleep disturbances
- Having changes in eating patterns
I’ve found that many babies also develop a slight temperature increase (below 38°C/100.4°F). Remember that high fevers, diarrhea, and severe symptoms aren’t typical teething symptoms and warrant medical attention.
For immediate relief, try these soothing techniques:
- Chilled (not frozen) teething toys
- Gentle gum massage
- Cold compresses

Common Age Ranges for Tooth Eruption
The typical baby develops their first tooth around 6 months of age, though I’ve seen considerable variation in this timeline among infants. Some babies may start teething as early as 3 months, while others might not show signs until their first birthday.
The eruption sequence generally follows this pattern:
- Lower central incisors (6-10 months)
- Upper central incisors (8-12 months)
- Upper/lower first molars (13-19 months)
- Canines (17-23 months)
Despite popular teething myths suggesting fever or diarrhea are normal symptoms, these actually warrant medical attention. For safe teething remedies, I recommend:
- Cold (not frozen) teething rings
- Gentle gum massage with clean fingers
- Soft, refrigerated washcloths
The Complete Baby Teeth Timeline
Although many parents expect teething to begin around 6 months, your baby’s dental journey actually starts long before their first tooth emerges. Those tiny teeth begin forming in the womb, with a full set of 20 primary teeth already developed in the jawbone at birth.
Key teething milestones typically follow this pattern:
- 6-10 months: Lower and upper central incisors appear
- 10-16 months: Lateral incisors emerge
- 13-19 months: First molars erupt
- 16-23 months: Canines break through
- 23-33 months: Second molars complete the set
Tooth eruption timing varies greatly between children. While some babies show signs of teething as early as 3 months, others may not get their first tooth until after 12 months. Most children have all 20 primary teeth by age 3.

Normal vs. Concerning Teething Symptoms
While you’re managing your baby’s teething discomfort, it’s important to recognize which symptoms are normal parts of the process and which might signal something else entirely.
Many teething myths persist about what’s normal during this developmental stage. Let’s clarify with a symptom comparison:
Normal teething signs:
- Increased drooling and facial rash
- Chewing on objects
- Sore, tender gums
- Mild irritability
- Slight temperature increase (not a true fever)
Concerning symptoms requiring medical attention:
- Fever above 38°C
- Diarrhea
- Persistent diaper rash
- Runny nose
- Excessive crying that can’t be soothed
If your baby experiences any concerning symptoms, don’t automatically attribute them to teething. Contact your healthcare provider to rule out other potential causes.

The Science Behind Tooth Development
Before your baby’s first tooth even breaks through the gums, an incredible developmental process has been underway for months. This journey begins around 6-8 weeks into pregnancy when soft tissues start forming, followed by hard tissue development after 3-4 months.
Tooth development follows a predictable pattern:
- Enamel forms during fetal development
- Dentin develops beneath the enamel
- Roots continue developing as teeth erupt
Both genetic factors and nutritional influence play significant roles in this process. Your baby’s tooth development timeline is largely predetermined by genetics, while adequate nutrition during pregnancy supports proper formation. Environmental elements like fluoride exposure can affect tooth hardening.
Understanding this developmental process helps explain why teeth emerge in a specific sequence—typically starting with lower central incisors around 6 months of age.
Caring for Your Baby’s New Teeth
Now that your baby’s first teeth are beginning to emerge, proper care becomes a central focus for maintaining their oral health. Even these tiny new teeth require regular attention for proper teething hygiene.
Start by:
- Gently wiping teeth with a clean, damp washcloth once daily
- Using a soft infant toothbrush when multiple teeth appear
- Avoiding toothpaste until your pediatrician recommends it
For tooth care during teething discomfort:
- Massage gums with a clean finger for about two minutes
- Offer chilled (not frozen) teething rings filled with distilled water
- Consider soft mesh feeders with chilled fruit for older babies
Remember that oral care habits established now create a foundation for lifelong dental health. Monitor new teeth regularly and schedule your baby’s first dental visit by their first birthday.

Frequently Asked Questions
Can Teething Cause Diaper Rash or Diarrhea?
I’ve seen many parents confused about this! Teething itself doesn’t directly cause diaper rash, but excess drooling (a common teething symptom) can lead to looser stools. Proper diaper care becomes extra important during this challenging phase.
Is Early or Late Teething Linked to Developmental Issues?
I’ve seen no significant evidence linking early or late teething to developmental delays. Teething milestones vary widely among babies, and research shows no direct correlation between tooth eruption timing and other developmental issues.
Can Thumb-Sucking Affect Teething or Tooth Alignment?
Yes, I’m concerned about thumb sucking effects on your child’s teeth. While occasional sucking is harmless, persistent habits beyond age 4 can cause alignment concerns including open bites and protruding front teeth.
Do Pacifiers Help or Hinder the Teething Process?
My niece found relief with silicone pacifiers during teething. I’ve seen that pacifiers can help as a soothing technique when babies are uncomfortable, but they shouldn’t be used long-term to avoid dental alignment issues.
Are There Genetic Factors That Influence When Teething Begins?
Yes, teething genetics definitely play a role in when your baby’s first teeth appear. I’ve seen research showing family history is a strong predictor of whether your little one will be an early or late teether.
