Babies can technically start teething as early as 2–3 months, but most get their first visible tooth between 4 and 7 months, with 6 months being the most common.

Quick Scoop

  • Many babies show early teething signs (drooling, chewing, fussiness) around 2–4 months, even before a tooth appears.
  • The first tooth usually pops through between 4–7 months, often one of the bottom front teeth.
  • Some perfectly healthy babies don’t get a first tooth until 9–12 months or even a bit later.
  • By about age 3, most kids have their full set of baby teeth.

Typical Teething Timeline

  • 2–4 months: Early signs like drooling and chewing on hands or toys may start, even with no tooth showing yet.
  • 4–7 months: Common window for the first tooth to erupt through the gums.
  • Around 6 months: Rough average age when many babies get that first tooth.
  • 8–12+ months: More front teeth and sometimes first molars begin appearing; being “late” here is usually still normal.
  • Up to 24–36 months: Remaining teeth, including molars and canines, come in until the full baby set is present.

Mini Forum-Style Perspective

“My baby started drooling and chewing like crazy at 3 months, but no teeth showed up for weeks. I thought something was wrong, but the pediatrician said it was normal and that teeth can ‘move’ under the gums long before you see them.”

“In some parent forums, people share stories of babies teething much later than average, and doctors often reassure them that late teething can still be totally normal.”

These kinds of stories line up with medical guidance that there’s a wide “normal” range.

When to Call the Doctor

You should get a pediatric checkup if:

  • Your baby seems in a lot of pain, has a high fever, or seems very unwell (these are not typical teething symptoms).
  • There are still no teeth by about 15–18 months and you’re worried; doctors often say timing varies, but can check for underlying issues.

Simple Example

  • Baby A: Starts drooling and chewing at 3 months, first tooth at 7 months → normal.
  • Baby B: Shows almost no signs, then suddenly has a tooth at 5 months → also normal.
  • Baby C: No teeth until 11–12 months, but otherwise growing well → often still considered within the normal range, just “late.”

SEO Bits (for your post)

  • Focus phrase “how soon can a baby start teething”:
    • Earliest common: around 2–3 months for signs, 3–4+ months for possible tooth eruption.
* Most typical: around 6 months.
  • “Latest news / trending topic / forum discussion”:
    • Recent pediatric content still emphasizes the same wide normal range (early signs at 2–4 months, first teeth around 4–7+ months).
* Parent forums continue to discuss confusion over fussiness vs teething vs growth spurts (“leaps”).
