An underbite is a type of malocclusion where the lower front teeth are positioned in front of the upper teeth when the mouth is closed. If you have an underbite, you might be wondering if Invisalign can help you fix it. Invisalign is a popular option for people who want to straighten their teeth without metal braces. But can it also correct an underbite?
Invisalign can fix many simple underbite cases where only the teeth are misaligned. However, if your underbite is more severe and involves the jaw bone you may need braces or surgery to correct it. Invisalign may not provide enough force or control to move the jaw bone into the right place.
Can Invisalign Fix Underbite?
Yes, Invisalign can potentially help fix an underbite. It works by gradually shifting your teeth into the correct alignment using a series of custom-made clear aligners. However, the effectiveness may depend on the severity of the underbite.

How Long Does Invisalign Take for Underbite?
The duration of Invisalign treatment for underbite depends on several factors such as:
The Severity of Your Underbite
The more severe your underbite is the longer it will take to correct it with Invisalign. Generally, mild to moderate underbites can be treated with Invisalign in 12 to 18 months while severe underbites may require 24 months or more.

The Complexity of Your Case
The more complex your case is the longer it will take to treat it with Invisalign. For example, if you have other dental issues besides an underbite such as crowding, spacing, or crossbite, you may need additional aligners or attachments to address them.
Your Compliance with The Treatment Plan
The success of your Invisalign treatment depends largely on how well you follow your orthodontist’s instructions. You need to wear your aligners for at least 20 to 22 hours per day and change them every one to two weeks as directed.
What Causes an Underbite?
An underbite can have various causes such as genetics environmental factors or developmental issues.
Some of the common causes are:
Heredity
An underbite can run in families and be inherited from parents or grandparents. If one or both parents have an underbite their children are more likely to have one as well.
Early Loss of Baby Teeth
Losing baby teeth too early can affect the development and alignment of the permanent teeth. The lower teeth may erupt before the upper teeth and prevent them from growing properly.
Prolonged Pacifier Use or Bottle Feeding
Using a pacifier or a bottle for too long can put pressure on the teeth and jaws and cause them to move out of place. The lower jaw may develop faster than the upper jaw and result in an underbite.
Mouth Breathing
Breathing through the mouth instead of the nose can affect the shape and position of the jaws and teeth. The tongue may rest on the lower teeth and push them forward, while the upper jaw may narrow and recede.

Conclusion
In conclusion, Invisalign can fix underbite in many cases but not all. It depends on the severity of the underbite the alignment of the teeth and the jaw and the patient’s compliance with the treatment plan. Invisalign is a convenient and discreet option for correcting mild to moderate underbite but it may not be suitable for severe cases that require surgery or more extensive orthodontic intervention.
