Baby Teeth Order: When a Delay Indicates a Problem  

Baby teeth order or the sequence in which they come in and are lost, varies a lot.  

Tracking each tooth is not necessary, but it is important to be aware of how this part of your child's dental development is progressing and to be alert for signs of potential problems.


The eruption pattern of primary and permanent teeth is  gradual and if your child is seeing a dentist regularly he or she will monitor their progress.

The approximate age each baby tooth should come in and fall out is shown on this chart.


Teething can be a stress filled time for parents.  Reviewing these signs of teething will help you know when a new tooth is on it's way.

Though teeth may take their sweet time, most baby teeth eventually come in and a few years later are lost  making room for the much larger permanent teeth.

The loss of baby teeth  can be  worrisome for parents.  It is  an awkward stage for every child's smile.

Their smile changes from cute little white teeth that are nicely aligned to a mouth full of misaligned partially erupted teeth that will take a few years and possibly a monthly trip to the orthodontist to grow into.  

Hardly anyone looks good with a mixed dentition.  But don't worry, those giant teeth will look great someday.

Ideally, the permanent teeth slowly grow and develop beneath baby teeth causing the roots of baby teeth to slowly resorb and the tooth to become loose.

When baby teeth don't fall out

Permanent teeth sometimes come in before the baby tooth falls out.  It can be a shock to see a permanent tooth growing in behind, above or beside a baby tooth that is overdue to fall out.  

Most of the time these stubborn baby teeth get loose and come out.  But sometimes they need to be removed by the dentist to make room for the new tooth.  

Your dentist can tell from your child's x-rays if the baby tooth has resorbed enough to come out on it's own or if it will need to be removed. 

Missing permanent teeth

Baby teeth that don't get loose and come out when they should can be a sign of a missing adult tooth.  

It is not unusual to be missing a permanent tooth.  The upper lateral incisors and pre molars are the most common adult teeth to be congenitally missing. 

Wisdom teeth are sometimes not present but since they often have to be removed, when they are missing they are hardly ever missed:) 

Though not ideal, missing  permanent teeth  is a common problem that can be successfully treated with the help of your dentist and orthodontist.  A tooth implant is the most likely solution and is much better than other ways of replacing a tooth.  

impacted permanent tooth

A baby tooth that doesn't come out on schedule can also indicate an impacted permanent tooth.   Upper canines are the most common teeth to be impacted.  These teeth stop erupting and need to be orthodontically moved into their functioning position.
