Overjet: What It Is and Why Your Smile Might Need Attention
Have you ever noticed someone whose upper front teeth seem to stick out a bit too far? Or maybe you’ve caught yourself in the mirror and wondered, “Is this normal?” That forward slant of the upper front teeth is what dentists call an overjet. It’s more common than you think - and while it might seem like a small thing, it can have a big impact on your smile, bite, and even confidence.
In this blog, let’s break down everything you need to know about an overjet in the simplest way possible- what it is, why it happens, whether it needs treatment, and how you can fix it if you want to.
What Is an Overjet?
In simple words, overjet is when your top front teeth are pushed ahead of your lower front teeth in a horizontal direction. You may have also heard the term “buck teeth”, which is the informal name for a noticeable overjet.
Now, don’t confuse overjet with overbite. While both involve your upper teeth overlapping your lower ones, the difference lies in the direction:
Overbite = Vertical overlap (up and down)
Overjet = Horizontal gap (front to back)
A slight overjet of 2-3 mm is considered normal. But when teeth protrude more than the normal range, it can start causing problems. With the way you eat, speak, and smile.
How to know if one has an Overjet?
Here are some signs to notice an overjet:
When your mouth is closed, your upper front teeth are visibly ahead of your lower front teeth
There’s a noticeable gap between the upper and lower teeth when biting
You sometimes bite into your lips or cheeks while eating
You find it difficult to close your lips naturally without pressure
All of this makes you feel self-conscious while smiling or speaking in social situations. If you’re unsure, your dentist or orthodontist can confirm the diagnosis with a smile examination.
What Causes an Overjet?
Overjet doesn’t happen overnight. There are many reasons which lead up to overjet:
1. Thumb Sucking or long-term pacifier use:
If a child sucks their thumb or uses pacifier for too long. It can put pressure on upper teeth and push them ahead. This leads to overjet.
2. Hereditary
Sometimes, it is in your genetics. If your parents had prominent front teeth or a smaller lower jaw. There is a chance you will end up having it too.
3. Tongue thrusting habit
This means that when the tongue pushes against the front teeth while swallowing. Over time, it can shift the teeth ahead of normal alignment.
4. Jaw size Mismatch
If your upper jaw is larger or your lower jaw is small. This may cause your upper teeth to stick out.
5. Missing teeth
Missing, crooked or misaligned teeth can affect how your bite comes along.
Is an Overjet a cosmetic problem?
No, treating overjet is not just a cosmetic fix. While many people undergo orthodontic treatment for appearance reasons. It can also lead to functional problems. This includes:
Difficulty biting or chewing food properly
Speech issues
Increased risk of trauma. As the front teeth stick out, they are more prone to injury
Jaw pain or discomfort
Tooth wear
In some cases, self-esteem issues, especially in children and teens
So, it’s totally okay to want a straighter smile for just cosmetic reasons. Fixing an overjet can also improve your oral health.
