Just imagine someone saying, ‘Hey, your teeth are crooked and it looks like you need to do something about it.’ The line between being mean and helpful is way too fine, so it’s better to say nothing. 

We’ve covered the topic of signs you need braces but let’s break down the types of malocclusions that Zenyum can help fix.

What is Malocclusion?

Having crooked teeth or a misaligned bite can also be a malocclusion. It basically means that your teeth and jaw do not naturally align which potentially affects the movement of your mouth. Let’s get into the three main types of malocclusion classes and what type of teeth misalignment is under them.

Class I Malocclusion

Class one is the most common malocclusion. The teeth alignment is typically good but there is a slight abnormality to the shape of the arch where the upper teeth overlap the lower teeth. 

Crowding and rotation

The two most basic misalignments is the problem of not having enough room in the jawbone to accommodate all teeth. This causes them to twist, turn and overlap when it begins growing. 


This teeth condition is basically when there are spaces in between the teeth. There are several reasons spaces can occur and can cause food to be trapped in between – even with the tiniest gaps.

Class II Malocclusion

The second malocclusion class is characterised by the upper jaw and teeth overlapping the lower jaw and teeth in protruding teeth (otherwise known as buck teeth).

Protruding teeth also known as buck teeth is when the upper front teeth overlap the bottom front teeth too much when your mouth is closed. This commonly occurs when you have a small lower jaw, or the lower jaw is shorter than the upper jaw.

Class III Malocclusion

This is the most severe malocclusion and it is characterised by the lower jaw teeth overlapping the upper jaw and teeth in an underbite.


An underbite is when your lower jaw rests in front of the upper jaw when your mouth is closed. However, correcting an underbite cannot totally be fixed with braces due to underlying bone development.


You could call this a mixture of both types of bite. It refers to when one or more of the lower teeth fit outside of the upper teeth. This may cause the jaw to grow lopsided and in turn, wear down teeth if left untreated.

How can you fix your misalignment?

If you didn’t know by now, Zenyum can help you correct your misalignment with our Invisible Braces. 

We have two types of treatments for different case complexity. Mild to moderate cases which usually only require movement of the first 8 teeth can be fixed with our ZenyumClear™ treatment. While our ZenyumClear™ Plus is for customers who have more complex teeth problems that require movement of all teeth.

It may be hard to tell whether correcting your bite should be a priority or if you even have a misalignment. This is why we offer a free smile assessment from the comfort of your own home.
