When do bottom incisors come in?

For many babies, the lower central incisors are the first teeth to erupt. A common lower incisors teething age is around 6 to 10 months, but healthy timing can vary. Some babies get their first bottom front teeth earlier, while others do not show signs until later. What matters most is the overall pattern of growth, comfort, and whether the gums and tooth movement seem consistent with normal eruption.

What the bottom front teeth eruption order usually looks like

Stage 1: No visible teeth yet

Before the first bottom teeth coming in, you may notice drooling, chewing, or mild gum sensitivity even when no tooth is visible.

Stage 2: One lower front tooth breaks through

It is common for one lower central incisor to appear first. The second bottom front tooth may follow soon after rather than erupting on the exact same day.

Stage 3: Both lower front teeth are in

Once both lower incisors have erupted, babies often move on to the next teeth in the usual sequence, though timing can still differ from child to child.

Bottom incisors teething signs parents often notice

Swollen or irritated gums

The gumline over the lower front teeth may look puffy, red, or tender before the tooth edge appears.

More drooling and chewing

Baby bottom front teeth teething often brings extra mouthing, chewing on fingers, and increased saliva.

Mild fussiness around feeding or sleep

Some babies become temporarily more irritable when lower front teeth erupt, especially during the days right before breakthrough.

What’s normal with lower front teeth eruption timeline

The lower front teeth eruption timeline is not identical for every baby. One tooth may come in before the other, symptoms may come and go, and visible eruption can happen quickly after days of gum swelling. If your baby seems uncomfortable but is otherwise acting well, eating reasonably, and staying hydrated, that often fits a typical teething pattern. If symptoms feel more intense, last longer than expected, or you are unsure whether this is teething at all, personalized guidance can help you decide what to watch next.

When parents often want extra guidance

No signs yet and you’re checking timing

If you’re asking when do lower front teeth erupt in babies, it can help to compare your baby’s age and current gum changes with the usual eruption window.

Only one bottom incisor is showing

Baby lower incisors order can still be normal when one tooth appears first and the second follows later.

Symptoms seem stronger than expected

If fussiness, feeding changes, or gum irritation feel hard to interpret, a focused assessment can help you sort common teething signs from concerns worth discussing further.
