Have you ever spotted a gap in someone's teeth and found it to be cute? Or maybe you've seen one in your own smile and wondered whether it was harmless, or if you should do something about it. That little gap, by the way, has a name: diastema teeth. It sounds scary, but it just means a gap between two teeth.
Some people actually wear their gap teeth diastema as a badge of honour! But for other people, they feel self-conscious and sometimes uncomfortable. So let's break down everything you need to know: What causes a diastema, when it is a problem, and how to fix gaps between teeth if you want to do something about it.
What Is a Diastema in Teeth?
Put simply, a diastema refers to a gap between teeth that is visible. The most familiar spot for a diastema is between the upper front teeth, which is often called a diastema in front tooth.
Some individuals have a small gap, which may not be noticeable and may not affect a person's appearance. Other individuals may have a more significant gap that affects the total symmetry of the smile. It can vary a lot and mostly depends on the cause, which is usually out of your control. It’s common in kids, teens, and adults, and doesn’t mean there’s a disease or anything wrong.
Knowing the area of concern, or cause, helps a practitioner determine whether it should be treated or left alone.
Why Do Diastema Teeth Happen?
Let’s face it, teeth don’t just decide to drift apart for fun. There’s usually a reason behind those gaps. Here are some of the most common culprits behind teeth diastema:
Genetics
Yep, sometimes it runs in the family. If your parents or siblings have gap teeth, there’s a good chance you inherited similar jaw or tooth proportions. Usually, this happens when your jaw is slightly too large for the size of your teeth, leaving extra space between them.
Missing or Undersized Teeth
When one tooth is missing or smaller than normal, it creates an imbalance. The neighboring teeth might shift into the open space, creating visible gaps.
Oversized Labial Frenum
This is a lesser-known but surprisingly common cause. The labial frenum is the little piece of tissue that connects your upper lip to your gums, right above your front teeth. When this tissue is too thick or extends too far down, it can push your front teeth apart, forming that trademark front gap.
Gum Disease
Now, here’s the not-so-cute side of it. Gum disease weakens the bone that supports your teeth. When that happens, teeth can start shifting slightly, and voila, you’ve got a gap where there wasn’t one before. This type of diastema is more common in adults than kids and needs attention fast because it’s usually a sign of underlying gum health issues.
Bad Oral Habits
Certain habits can physically push your teeth out of alignment. Things like thumb-sucking, tongue thrusting (pressing your tongue against the front teeth when swallowing), or even lip biting can gradually create a gap.
Normal Development in Kids
If your child has gap teeth (diastema), don’t panic. It’s quite normal during the “mixed dentition” stage, when baby teeth fall out and adult teeth start coming in. Most of those gaps close naturally once the permanent teeth settle in place.
Breaking It Down
| Cause | Why It Happens |
| Genetics | Inherited jaw-tooth size ratio |
| Missing or undersized teeth | Neighbouring teeth drift into space |
| Thick labial frenum | Pushes front teeth apart |
| Gum disease | Bone loss causes shifting |
| Habits (thumb-sucking, etc.) | Constant pressure moves teeth |
| Normal growth in kids | Temporary spacing before adult teeth come in |
Are Diastema Teeth Dangerous?
Gaps between teeth can occur for various reasons, and their significance can vary from person to person. While many may have a gap that is primarily cosmetic and doesn't imply any underlying dental issue, there are specific situations where attention might be warranted.
Aesthetic Concerns
For many individuals, the primary consideration is the visual aspect of having a gap. An obvious gap, especially in the front teeth, can lead to self-consciousness, impacting a person’s confidence and willingness to smile openly. Those who feel conscious about their appearance may seek solutions to close the gap or enhance their smile.
Speech Problems
In some cases, larger gaps can influence how a person articulates certain sounds. The airflow through the mouth can be altered, leading to challenges in pronouncing consonants like "s" or "th." This can be particularly frustrating for children who are still developing their speech skills, which may impact their communication abilities.
Food Traps and Oral Hygiene Issues
Gaps between teeth can create spaces that trap food particles more easily, particularly around the molars. If not properly managed, these spaces can lead to increased plaque build-up, which elevates the risk for cavities and gum disease. Effective dental hygiene becomes even more critical, requiring diligence in brushing and flossing to prevent oral health issues.
Sign of Gum Disease
If a gap appears suddenly during adulthood, it may be a sign of gum disease or other underlying dental issues, such as weakened or receding gums. This situation suggests that it's time to consult with a dentist, as early intervention can lead to better outcomes and preserve oral health.
Progressive Widening
Diastema can sometimes be indicative of bone loss or certain habits, such as thumb sucking or tongue thrusting. If these issues are not addressed, the gap may continue to widen over time, leading to more significant dental concerns.
While a diastema is not always indicative of a serious problem, understanding the reasons behind it can help you make informed decisions about whether to seek treatment or embrace your unique smile. Whether it’s for aesthetic reasons, health concerns, or a combination of both, consulting with a dental professional can provide clarity and options tailored to your individual needs.
How to Treat Diastema Teeth
Alright, here’s the part everyone’s curious about: how to fix a diastema in teeth. There’s no one-size-fits-all solution. It depends on the cause, the size of the gap, and what kind of results you’re after.
Here are the most common treatment options (with their pros and cons):
Orthodontic Treatment (Braces or Clear Aligners)
This is the go-to solution for most cases of diastema in front teeth. Orthodontic treatments like braces or clear aligners gradually move the teeth closer together until the gap disappears.
- Braces: Metal or ceramic brackets with wires that guide teeth into place.
- Clear Aligners: Transparent, removable trays that do the same job discreetly.
Pros:
- Long-term fix that addresses root causes.
- Aligns all your teeth, not just the gap.
Cons:
- Requires time and patience (usually several months).
- Needs commitment to aftercare (wearing retainers).
If you’re not a fan of the “brace-face” look, that’s where ALIGNERCO comes in, especially for Canadians looking for a more budget-friendly, convenient way to fix teeth diastema.
Dental Bonding
Bonding is a quick cosmetic fix. A tooth-colored resin is applied and shaped to close the space between your teeth. It’s painless, non-invasive, and often done in a single visit.
Pros:
- Fast and affordable.
- Looks natural.
Cons:
- Can chip or stain over time.
- Doesn’t solve the underlying cause.
Veneers
Veneers are thin porcelain shells placed over the front surface of teeth. They can make gaps vanish instantly and give your smile a uniform, flawless look.
Pros:
- Long-lasting and resistant to stains.
- Great for cosmetic transformation.
Cons:
- Requires enamel removal.
- More expensive than bonding.
Frenectomy (Tissue Surgery)
If your diastema front teeth are caused by an oversized labial frenum, no amount of aligners or braces will fully close the gap unless that tissue is reduced. A frenectomy is a minor surgical procedure where the excess tissue is trimmed. It’s quick and usually painless under local anesthesia.
Dental Implants or Bridges
If your gap exists because of a missing tooth, then orthodontics alone won’t help. In that case, your dentist might suggest an implant or bridge to restore the missing space and balance the smile.
Treating Gum Disease First
If the gap results from gum problems, no cosmetic treatment should come before restoring gum health. Scaling, deep cleaning, and proper maintenance are crucial to prevent further tooth movement.
How to Prevent Diastema Teeth
You can’t exactly bargain with genetics, but you can take charge of your habits and oral care. Most cases of diastema teeth, caused by lifestyle or gum issues, can actually be prevented with a little extra attention. Here’s how to stay one step ahead:
Maintain Good Oral Hygiene
Healthy gums are the backbone of a strong smile. Brush twice daily with a soft-bristled brush and don’t skip flossing, it’s the only way to clean those tight spaces plaque loves. Flossing keeps bacteria in check and helps prevent gum disease, one of the sneaky causes behind shifting teeth and gaps. And if you want extra freshness? Add an antimicrobial mouthwash to keep your gums protected and your breath minty clean.
Avoid Harmful Habits
Sometimes, it’s not your genes, it’s your habits. Thumb-sucking, tongue thrusting can slowly push them apart. If your child shows early signs of gap teeth or diastema, talk to a pediatric dentist. Gentle habit-correcting exercises can make a big difference before alignment issues set in.
Keep up with Regular Dental Visits
Let’s face it, skipping a dental check-up is easy, until it’s not. Visiting your dentist twice a year helps spot gum recession or tiny shifts before they turn into visible gaps. For kids, these visits are crucial since their teeth and jaws are still developing.
Use Retainers after Orthodontic Treatment
Once your diastema in front teeth is fixed, retainers are your best friend. They hold your teeth in place while everything settles. Missing even a few nights can undo months of progress, so wear them consistently and replace them if they loosen up.
Keep an Eye on Your Gums
Your gums say more than you think. Swelling, tenderness, or slight movement in your teeth are red flags. If a new space appears, see your dentist early; treating gum issues quickly can stop further shifting.

FAQs
1. What causes gaps between teeth (diastema)?
Diastema can occur due to natural spacing in the jaw, missing teeth, habits like thumb-sucking, tongue thrusting, or when the piece of tissue between the gums and front teeth (the frenum) is too large.
2. Are diastema teeth genetic or caused by habits?
Both. Genetics can determine jaw size and tooth spacing, while habits like thumb-sucking or tongue pushing can widen gaps over time.
3. Is having a gap between teeth normal?
Yes. Many people have small gaps, especially between the front teeth. It’s common and not always a medical concern unless it affects the bite or causes self-confidence issues.
4. What are the risks of leaving a diastema untreated?
Sometimes none, but gaps can lead to food trapping, gum irritation, shifting of surrounding teeth, and bite misalignment if they widen over time.
5. How can diastema be prevented in children?
Encouraging good oral habits (no thumb-sucking or lip-biting), treating early gum issues, and regular dental check-ups can help. A dentist can guide early treatment if gaps start to widen.
6. Can braces or aligners fix a diastema?
Yes. Braces and clear aligners can close gaps by gently moving teeth into proper alignment. Treatment time varies based on the size of the gap and overall dental structure.
