Most children lose their final baby tooth around age 12. In many cases, when a baby tooth falls out, the permanent tooth follows shortly after. However, if a baby tooth is lost and no adult tooth erupts within a reasonable time, there may be an underlying issue.
The permanent tooth could be impacted, blocked by crowding, or congenitally missing. The only way to know for sure is through a comprehensive dental exam and diagnostic X-rays.
Early evaluation helps prevent long-term bite and alignment concerns.
What Happens If a Permanent Tooth Never Develops?
When a child is missing a permanent tooth, there are generally three possible treatment paths:
- Preserve the baby tooth for as long as possible
- Replace the missing tooth with a bridge or dental implant
- Close the space orthodontically
Not every child is a candidate for all three options. Bite alignment, crowding, and overall dental development all influence the best course of action.
In some cases, keeping the baby tooth is ideal—especially if it is healthy and stable. Many baby teeth can remain functional for years. However, if the tooth lacks proper root support or develops decay, replacement may eventually be necessary.
When Is Orthodontic Space Closure the Right Choice?
If crowding or bite issues already exist, closing the space orthodontically may be the most effective solution.
For example:
- In cases of underbite or lower crowding, removing certain lower teeth may improve alignment.
- If a bicuspid is missing, sometimes only one additional permanent tooth needs removal to balance the bite.
- When upper teeth protrude or crowd, upper bicuspids may be considered for removal.
- Patients missing upper lateral incisors or bicuspids may sometimes close the space without needing implants.
However, when bite and crowding are not present, closing spaces can sometimes create unnecessary complications. Lengthy treatment may affect bone, gum health, or arch symmetry.
Each case must be carefully evaluated.
How Do We Determine the Best Treatment Plan?
There is no one-size-fits-all solution. A comprehensive orthodontic evaluation assesses:
- Bite alignment
- Degree of crowding
- Jaw development
- Overall dental health
If orthodontic closure is possible and beneficial, it will be recommended. If replacement is the better option, planning will begin at the appropriate time.

Frequently Asked Questions
Learning that your child may have a missing permanent tooth or an extra tooth can raise a lot of questions. You might be wondering what it means long-term, whether it affects their smile, or if treatment is urgent. Below are answers to common questions parents frequently search when navigating this situation.
Is it common for children to be born without permanent teeth?
Yes, it’s more common than many parents realize. Some children are congenitally missing one or more permanent teeth, especially upper lateral incisors or bicuspids. This condition can run in families. Early dental X-rays help identify missing teeth before they become a bigger concern.
At what age can you tell if a permanent tooth is missing?
In many cases, missing permanent teeth can be identified between ages 6 and 9 using routine dental X-rays. Early detection allows your dentist or orthodontist to plan ahead and guide proper tooth development.
Will my child need braces if they are missing a tooth?
Not always—but orthodontic treatment is often part of the overall plan. Braces may help close gaps, create space for a future implant, or improve bite alignment. Each case is unique and depends on crowding, jaw growth, and overall dental development.
Is treatment urgent if my child is missing a permanent tooth?
In most cases, it is not an emergency—but early evaluation is important. Timely planning allows for more conservative, effective solutions and prevents unnecessary complications later.
What problems can extra teeth cause?
Extra teeth (supernumerary teeth) can block normal eruption, create crowding, or shift neighboring teeth out of position. In some cases, they may not cause symptoms at all—but monitoring is important to prevent future alignment issues.
