What's the whole baby teeth timeline, from first tooth to last one lost?

The whole arc, stage by stage

Baby teeth move through four loose stages rather than one steady drip of new teeth.

• Infancy. A first tooth typically arrives somewhere around six months old, often a bottom front tooth, though a wide range on either side is still ordinary. More on this stretch lives on our babies page.
• Toddler years. The rest of the twenty-tooth set generally fills in over the next couple of years, arriving in waves rather than one at a time, with most children holding a complete set by preschool age. Our toddlers page covers what that stretch looks like day to day.
• Early elementary. Baby teeth begin loosening on their own schedule, commonly starting around age 5 or 6, generally in close to the same order they first arrived.
• Later elementary into the tween years. The final baby teeth finish their exit somewhere around middle school age, while permanent teeth keep arriving behind them for years afterward. Growth and alignment get checked at every routine visit here, which is how this whole handoff gets watched without becoming its own separate errand.

Why no two kids match the chart exactly

These ranges are wide on purpose. One baby might show a tooth as early as the three-month mark, while another baby's first birthday photo still shows a bare, gummy grin, and neither one is anything to worry about. The same spread shows up again later: one child can lose a first tooth a full year ahead of a sibling, and both are perfectly normal.

Genetics plays a real role in both directions. Arriving early as a baby often lines up with losing teeth a bit early as a school age child, and the reverse holds too. Comparing your child against a chart online tends to create more worry than it resolves. Mentioning your child's actual pace at a routine visit gets a far more useful answer than scrolling for one.

When the overall pattern, not one tooth, is worth a call

• One side of the mouth is running noticeably ahead of the other, rather than the usual close-together pattern
• Nothing at all has arrived or budged well outside either range above, on either end of the timeline
• A permanent tooth is visible behind a baby tooth that shows no sign of loosening
• Any tooth changes suddenly, rather than gradually, after a fall or a bump during play

None of these are common, and none of them mean anything is seriously wrong on their own. They are simply worth a call rather than a wait. One number reaches both offices, Monday to Friday, 8 to 5, and a real human answers: (239) 482-2722.

Where to go for the tooth-by-tooth detail

This page is the wide-angle view on purpose. For the fuller order teeth tend to follow on the way in, or the order they tend to follow on the way out, your pediatric dentist can walk through exactly what is typical at your child's next checkup and compare it against what your own child's mouth is actually doing.

Our infant dental care page covers the earliest stretch in more depth, and the glossary defines terms like eruption in plain language if one comes up at a visit. Whatever else comes up along the way is exactly what Quick Answers is here for.
