Teething gets blamed for almost everything between four and twelve months — sleep disruptions, fussiness, appetite changes — and sometimes it’s the real cause, and sometimes it’s a convenient explanation for something else entirely. A rough timeline helps sort out which is which.
A general timeline (every baby varies)
- 6–10 months: Bottom and top front teeth (central incisors) typically arrive first.
- 9–13 months: Lateral incisors (next to the front teeth) usually follow.
- 13–19 months: First molars, often the most uncomfortable, tend to arrive after the first birthday for many babies — though some start earlier.
These ranges are wide for a reason — some babies get their first tooth at three months, others closer to twelve, and both are within normal variation.
What’s actually teething
- Increased drooling
- Chewing or gnawing on hands, toys, or anything within reach
- Swollen, tender gums, sometimes with a visible white spot where a tooth is close to breaking through
- Mild, short-term fussiness, especially right before a tooth emerges
High fever, diarrhea, or significant congestion are commonly attributed to teething but aren’t well-supported as actual symptoms of it. If these show up, it’s worth checking with your pediatrician rather than assuming a tooth is the cause.
What actually helps
Safe teething toys (particularly ones that can be chilled), gentle gum massage with a clean finger, and, if needed, appropriate infant pain relief as advised by your pediatrician for particularly rough days. Avoid teething necklaces and numbing gels containing benzocaine, both of which carry safety concerns — check current pediatric guidance before using any teething product.
Why it’s worth tracking
Noting when a tooth actually breaks through (not just when symptoms start) helps you look back and see whether a rough sleep stretch actually lined up with teething, or whether it was something else — useful information for future rough patches too.
