How to Fix a Gap Between Front Teeth
A gap between the front teeth — known clinically as a diastema — can be caused by several factors, including jaw size, missing teeth, oral habits, or gum disease. The good news is that multiple effective treatment options are available, ranging from orthodontics to cosmetic dental procedures. A licensed dentist can assess your specific situation and recommend the most appropriate solution.
What Causes a Gap Between Front Teeth?
Understanding the root cause of your gap is the first step toward choosing the right treatment. Here are the most common reasons gaps develop between front teeth:
Jaw and Tooth Size Mismatch
When teeth are too small relative to the jawbone, extra space is left between them. This is one of the most common structural causes of front tooth gaps. Conversely, teeth that are too large for the jaw lead to crowding.
Missing or Undersized Teeth
Sometimes certain teeth are congenitally missing or smaller than average. This occurs most often with the upper lateral incisors — the teeth on either side of the two front teeth. When these teeth are absent or undersized, noticeable spaces can develop in the upper arch.
Thumb Sucking and Oral Habits
Prolonged thumb sucking or dummy (pacifier) use in childhood can push the front teeth forward, gradually creating a gap. These habits are best addressed early — ideally during childhood dental visits — to prevent long-term alignment issues.
Tongue Thrust
Most people press their tongue against the roof of the mouth when swallowing. Some individuals develop a pattern called tongue thrust, where the tongue pushes against the front teeth during swallowing instead. Over time, this repeated pressure moves the front teeth forward and creates spaces between them.
Periodontal (Gum) Disease
Advanced gum disease can cause the bone and tissue supporting the teeth to weaken, allowing teeth to shift and gaps to form. If gum disease is the underlying cause, it must be treated before any cosmetic or restorative work is carried out. Learn more about our periodontal care services at Expressions Dental.
Temporary Gaps in Children
Children commonly have temporary spaces between their teeth as baby teeth fall out and permanent teeth emerge. In most cases, these gaps close naturally as the adult teeth settle into their final positions. If you are concerned about your child’s tooth spacing, our team offers dedicated dental care for children in Calgary.
Treatment Options for Gaps Between Front Teeth
The right treatment for a front tooth gap depends on the cause, the size of the gap, and your overall oral health. Here is an overview of the most effective options available at a licensed dental clinic in Calgary NW:
Invisalign or Orthodontic Braces
Orthodontic treatment is one of the most comprehensive ways to close a gap, particularly when multiple teeth need repositioning. Invisalign in Calgary NW uses a series of clear, removable aligners to gradually shift teeth into the correct position — a discreet and comfortable alternative to traditional braces.
Porcelain Veneers
Veneers are thin shells of porcelain bonded to the front surface of the teeth. They are an excellent option for closing small to moderate gaps while also improving the shape, colour, and overall appearance of your smile. Visit our porcelain veneers page to learn more about this popular cosmetic treatment.
Dental Crowns
If the teeth adjacent to the gap are undersized or structurally compromised, dental crowns in Calgary NW can be used to widen and restore them, effectively eliminating the space while strengthening the teeth at the same time.
Dental Bonding (Composite Resin)
Composite bonding involves applying tooth-coloured resin directly to the surface of the teeth to fill in gaps and reshape them. It is a cost-effective and minimally invasive option that can often be completed in a single appointment. Ask your dentist whether composite white fillings and bonding is suitable for your situation.
Dental Implants
If the gap exists because a tooth is missing entirely, a dental implant in Calgary NW is generally the most natural-looking and long-lasting replacement option. An implant replaces both the root and crown of the missing tooth, preserving jawbone density and maintaining the surrounding teeth’s positions.
Dental Bridges and Partial Dentures
For patients who are not candidates for implants, a dental bridge or partial denture can restore the appearance and function of a smile affected by missing teeth.
Periodontal Treatment
When gum disease is the cause of tooth movement and spacing, periodontal treatment must come first. Only once the gums and supporting bone are healthy can cosmetic or restorative work be safely performed.
How Do I Know Which Treatment Is Right for Me?
Every patient’s situation is unique. The most important step is scheduling a consultation with a licensed dentist who can examine your teeth, gums, and bite, and discuss which option aligns best with your goals, timeline, and budget. Factors such as the size of the gap, its cause, your age, and your overall oral health will all influence the recommended approach.
At Expressions Dental in Calgary NW, our licensed dental team takes the time to understand your concerns and explain all available options clearly before any treatment begins. Whether you are looking for a quick cosmetic fix or a more comprehensive restorative solution, we are here to help you achieve a confident, healthy smile.

Frequently Asked Questions
What is the most common cause of a gap between front teeth?
The most common causes include a size mismatch between the teeth and jawbone, missing or undersized lateral incisors, prolonged thumb sucking, and tongue thrust habits. In adults, gum disease can also cause teeth to shift and create new gaps. A licensed dentist can identify the underlying cause during a routine examination.
Can a gap between front teeth close on its own?
In children, gaps between baby teeth or newly erupted permanent teeth often close naturally as the remaining adult teeth come in. However, gaps in adult teeth rarely close without treatment. If you are concerned about a gap that is not closing or is getting wider, it is worth having it assessed by a dentist.
Is Invisalign effective for closing front tooth gaps?
Yes, Invisalign is a highly effective option for closing gaps between front teeth, particularly when the gap is caused by spacing rather than a missing tooth. The clear aligners gradually shift the teeth into the correct position without the appearance of traditional metal braces. Visit our Invisalign Calgary NW page to learn more about this treatment.
How long does it take to fix a gap between front teeth?
Treatment time varies depending on the method chosen and the size of the gap. Dental bonding can be completed in a single appointment, while Invisalign or braces may take several months to over a year. Dental implants typically require a few months from start to finish due to the healing process. Your dentist will give you a realistic timeline during your consultation.
Will fixing a gap between my teeth be covered by dental insurance?
Coverage depends on the cause of the gap and the treatment recommended. Orthodontic treatments like Invisalign may have partial coverage, while purely cosmetic procedures such as veneers are often not covered. Expressions Dental offers direct billing to most major insurance providers and flexible financing options — visit our insurance and financing pages for more details.
Is dental bonding a good option for small front tooth gaps?
Dental bonding using composite resin is an excellent, minimally invasive option for small to moderate gaps. It is one of the most affordable cosmetic treatments, requires little to no enamel removal, and can typically be completed in one visit. However, bonding may not be as durable as veneers or crowns and may require touch-ups over time.
What happens if a front tooth gap is caused by gum disease?
If gum disease is responsible for tooth movement and spacing, it must be treated before any cosmetic or restorative work can be done. Untreated periodontal disease can cause continued bone loss and tooth movement, which would undermine any gap-closing treatment. Expressions Dental offers comprehensive periodontal care to restore gum health before proceeding with smile improvements.
