Spacing (Gaps Between Teeth)
What Is Dental Spacing?
Have you noticed gaps between your child's teeth?
Maybe there's a space between the front teeth, several gaps throughout the smile, or spaces that seem to be getting larger as your child grows.
Dental spacing simply means there is extra room between the teeth.
While many people think spacing is a problem, that's not always true. In fact, some spacing is completely normal and even beneficial during childhood.
The key is determining whether the spaces are part of normal development or whether they may benefit from orthodontic treatment.
Why Does Spacing Happen?
Spacing occurs when there is more room in the jaws than is needed for the teeth.
Several factors can contribute to spacing, including:
Genetics
Small teeth
Large jaws
Missing teeth
Extra space created during growth
Thumb sucking habits
Tongue posture habits
Gum tissue attachments between the front teeth
Certain developmental conditions
Some children simply inherit smaller teeth or larger jaws. Others develop spaces because permanent teeth are missing or because of differences in how their teeth erupt.
Understanding why the spacing exists is one of the most important parts of treatment planning.
How Does Spacing Change Over Time?
Spacing in Baby Teeth
Many parents are surprised to learn that spacing in baby teeth is usually a good thing.
Baby teeth are much smaller than the permanent teeth that will eventually replace them.
Those spaces help create room for the larger adult teeth and often reduce the likelihood of severe crowding later.
In fact, a child with no spacing between baby teeth is often more likely to develop crowding than a child with spaces.
Spacing During the Transition to Adult Teeth
This is when spacing often changes the most.
As permanent teeth erupt, some spaces naturally close while others remain.
One of the most common examples is a space between the upper front teeth.
Many children develop a gap between their front teeth before their canine teeth erupt. As the canine teeth come in, they often help push the front teeth together and reduce the spacing.
This natural correction is usually modest, but it does occur and is one reason we don't rush every child with a front tooth gap into treatment.
Spacing in Permanent Teeth
Once the permanent teeth have erupted, spacing becomes easier to evaluate.
Some spaces are primarily cosmetic.
Others may affect tooth position, bite relationships, or long-term stability.
Large spaces in the front teeth may allow teeth to tip forward over time, making them more vulnerable to injury.
Spacing in Adults
Adults with spacing often seek treatment because they are unhappy with the appearance of their smile.
In some cases, spacing may also contribute to:
Food trapping
Gum irritation
Bite concerns
Difficulty maintaining certain areas
Fortunately, spacing can often be corrected successfully with orthodontic treatment.
Will My Child Outgrow Spacing?
Sometimes.
Some spaces close naturally as permanent teeth erupt.
This is especially common during the mixed dentition years when the canine teeth are developing and moving into position.
However, significant spacing often remains unless the underlying cause changes.
The most important step is determining whether the spacing is part of normal development or whether treatment may eventually be beneficial.
Does Spacing Need to Be Fixed?
Not always.
Many spaces are completely healthy and require no treatment.
However, there are situations where treatment may be beneficial.
Small Spaces Can Sometimes Cause Problems
Many parents assume large gaps are the biggest concern.
Surprisingly, small spaces can sometimes be more problematic.
Small spaces may trap food between teeth, making them harder to clean and increasing the risk of gum inflammation and periodontal problems over time.
Large Spaces Can Affect Tooth Position
Large spaces, particularly between the upper front teeth, may allow teeth to tip forward.
As teeth become more prominent, they may become more vulnerable to injury during sports, falls, and everyday childhood activities.
The decision to treat depends on the size of the spaces, the patient's age, and the cause of the spacing.
Why Do Orthodontists Recommend Treatment?
Orthodontic treatment is often recommended for one or more of three reasons.
Functional and Oral Health Reasons
Sometimes spacing affects the health and function of the teeth and gums.
Examples include:
Food trapping
Difficulty cleaning between teeth
Gum inflammation
Periodontal concerns
Bite problems
Increased risk of dental trauma from protruding teeth
When these issues are present, treatment may help improve long-term oral health and function.
Social Reasons
Children and teenagers do not experience their smile in a vacuum.
Unfortunately, dental appearance can sometimes influence how children are treated by their peers. Spaces between teeth may become the focus of teasing, unwanted attention, or social discomfort.
While every child is different, these experiences can have a meaningful impact on daily life.
Psychological Reasons
Perhaps most importantly, orthodontic treatment can affect how patients see themselves.
Parents sometimes tell us:
"My child won't smile in pictures."
"They cover their mouth when they laugh."
"They're embarrassed by the gap."
"They're being teased at school."
These concerns are real and deserve to be taken seriously.
At Smile Squad, we believe a healthy smile is about more than teeth. It's also about confidence, self-esteem, and quality of life.
There are times when spacing may not pose a significant health risk, but treatment is still appropriate because the space is having a meaningful impact on a child's confidence or social well-being.
Does Every Gap Between the Front Teeth Need Treatment?
No.
A gap between the upper front teeth is one of the most common concerns parents bring to our office.
In many children, this spacing is a normal stage of development.
As the permanent canine teeth erupt, they often help reduce the space naturally.
Because of this, treatment is not always necessary immediately.
At Smile Squad, we evaluate the child's age, stage of development, eruption pattern, and overall bite before recommending treatment.
Sometimes treatment is appropriate.
Sometimes the best recommendation is simply to monitor development and allow nature to do some of the work.
When Is the Best Time to Fix Spacing?
The answer depends on the cause of the spacing.
Some spaces are best monitored while permanent teeth continue erupting.
Others may benefit from treatment once all permanent teeth are present.
At Smile Squad, we focus on understanding why the spacing exists before recommending treatment.
Whether the concern is oral health, appearance, confidence, or a combination of factors, treatment timing should be individualized for each patient.
Our goal is not to close every space as soon as possible. Our goal is to treat the right problem at the right time.
How Is Spacing Fixed?
Treatment depends on the patient's age, the cause of the spacing, and the amount of space present.
Observation
Some spaces close naturally as the permanent teeth erupt.
In these situations, monitoring may be all that is needed.
Braces
Braces are one of the most effective ways to close spaces and improve overall tooth alignment.
Clear Aligners
Many teens and adults can successfully close spaces using clear aligners.
Addressing Missing Teeth
If spacing is caused by missing teeth, treatment may involve orthodontics as well as restorative options such as implants or bridges.
Frenectomy
Some spaces between the upper front teeth are influenced by a thick attachment of gum tissue called the frenum.
In selected cases, a frenectomy may be recommended as part of treatment.
Not every front tooth gap requires a frenectomy, which is why proper diagnosis is important.
Why Is Oral Hygiene Important During Space Closure?
Many parents are surprised to learn that closing spaces changes the shape of the gum tissue between the teeth.
As teeth move together, the gums must adapt to the new tooth positions.
If plaque and inflammation are present, the gum tissue may become enlarged or puffy during treatment.
Excellent brushing, flossing, and regular dental cleanings help the gums heal and adapt properly as spaces close.
In some situations, additional gum contouring procedures may be recommended after orthodontic treatment. Maintaining excellent oral hygiene can often reduce the need for those procedures.
Will the Spaces Reopen After Treatment?
Sometimes.
Unfortunately, some spaces have a higher tendency to reopen than others.
This is especially true for spaces between the upper front teeth.
For this reason, retention is extremely important.
Many patients will wear removable retainers after treatment, while others may benefit from a fixed retainer bonded behind the teeth.
At Smile Squad, we spend just as much time thinking about how to keep spaces closed as we do closing them in the first place.
Signs Parents Should Watch For
You may want to schedule an orthodontic evaluation if you notice:
Large gaps between teeth
A space between the upper front teeth that continues to grow
Food frequently getting trapped between teeth
Teeth beginning to tip forward
Missing permanent teeth
Delayed tooth eruption
Concerns about smile appearance
A child who avoids smiling in photographs
Why Early Diagnosis Matters
Early diagnosis helps us determine whether spacing is a normal part of development or a sign of an underlying concern.
Some spaces will close naturally.
Others may indicate missing teeth, eruption problems, or bite concerns that deserve closer attention.
An early evaluation also gives us an opportunity to discuss concerns that go beyond oral health, including confidence, self-esteem, and social experiences.
The purpose of an orthodontic evaluation is not to close every gap.
The purpose is to understand why the space exists and determine whether treatment is likely to provide a meaningful benefit.
The goal is to provide the right treatment at the right time.

Frequently Asked Questions About Spacing
Are gaps between baby teeth normal?
Yes. In fact, spacing between baby teeth is often beneficial because it creates room for the larger permanent teeth.
Will my child's front tooth gap close on its own?
Sometimes. As the permanent canine teeth erupt, they often help reduce spacing between the front teeth.
Are small spaces worse than large spaces?
Sometimes. Small spaces can trap food and make cleaning more difficult, increasing the risk of gum problems.
Can spacing make teeth stick out?
Yes. Large spaces between the front teeth may allow teeth to tip forward, increasing their prominence and risk of injury.
What is a frenectomy?
A frenectomy is a procedure that removes or reshapes a thick gum tissue attachment that may contribute to spacing between the front teeth.
Can clear aligners close gaps?
Yes. Many spaces can be treated successfully with clear aligners.
Will my spaces come back after treatment?
Some spaces have a tendency to reopen, particularly between the upper front teeth. This is why retainers are so important.
Will I need a permanent retainer?
Some patients benefit from a fixed retainer behind the teeth to help maintain long-term stability after space closure.
My child doesn't smile in pictures because of a gap. Is treatment reasonable?
Absolutely. Orthodontic treatment is not only about oral health. Confidence, self-esteem, and social well-being are also important considerations when deciding whether treatment may be beneficial.
