Have you ever seen someone with their bottom teeth pushed further out than the top teeth when they bite down? This is called a Class 3 bite or an underbite. This is not just a cosmetic issue, it can impact speech and chewing as well. Some cases are mild and do not require treatment while other cases may require treatment to correct the alignment for proper functioning. Treatment options could involve the use of orthodontics or a surgical approach to fix the bite correction. Thanks to modern dentistry, there are now non-surgical ways of managing a Class 3 bite successfully.
In this blog you will learn more about what a Class 3 bite is, what causes it, how it is diagnosed, what treatment options are available for a Class 3 bite, and why Aligner32 Clear Aligners are a top choice.
Understanding Class 3 Bite: What Causes It?
A Class 3 bite occurs when the lower jaw (mandible) extends forward beyond the upper jaw. Several factors contribute to this misalignment, including genetics, irregular jaw development, and childhood habits. Let’s examine these in more detail.
Genetic Influence
There is usually a strong hereditary influence on underbites. If one of the parents or grandparents has a Class 3 bite, their child has a higher chance of having the same sort of bite. Research has also shown that your ethnicity may play a part too. For example, people of Southeast Asian descent, have more of a prevalence of underbites.
Irregular Jaw Development
In some situations, the lower jaw is bigger than the upper jaw, which is termed an underbite. On the other hand, if the upper jaw does not develop enough, the lower jaw may seem larger. Usually, this discrepancy develops in childhood and will get worse over time.
Early Childhood Habits
Certain behaviors in early childhood can contribute to developing an underbite, such as:
- Extended thumb-sucking
- Prolonged pacifier use past the age of three
- Tongue thrusting (pressing the tongue against the lower teeth)
- Mouth breathing due to nasal congestion or allergies
Diagnosing Class 3 Bite
A dentist or orthodontist can diagnose a Class 3 bite through a combination of clinical evaluation and imaging techniques such as X-rays, 3D scans, and dental impressions. But if you are looking for an online assessment, Aligner32 offers just that. You have to fill in a small survey to get your answers. It will tell you if you are eligible for clear aligners treatment or not. These assessments can also help determine the severity of the bite misalignment and guide the selection of an appropriate treatment plan.

Preventing Class 3 Bite
Parents cannot prevent genetic factors from contributing to a Class 3 bite, but there may be some things a parent may be able to do to minimize the child’s Class 3 bite risk:
- Stop Thumb-Sucking and Pacifier Use: These habits have been shown, particularly in children after 3 years of age, to influence jaw growth.
- Keep Track of Jaw Growth: Regular checks by a dentist can help ensure the jaw is growing properly and if found not to be growing properly, can lead to early and timely intervention.
- Promote Healthy Oral Habits: Teaching children healthy oral habits like keeping their teeth clean and avoiding harmful foods, can facilitate good growth and development of the teeth and jaws.
Non-Surgical Treatment Options
Many individuals seek non-surgical methods to correct their Class 3 bite. The two most common approaches include braces and clear aligners.
Braces: A Traditional Approach
- Metal Braces: Durable and effective, though highly visible.
- Ceramic Braces: Less noticeable due to their tooth-colored material.
- Damon Braces: Self-ligating braces that allow for smoother movement and reduced discomfort.
While braces are effective, they require frequent adjustments and often involve extended treatment durations.
Clear Aligners: A Modern Alternative
Clear aligners, such as Aligner32 Clear Aligners, offer a comfortable and discreet solution for Class 3 bite correction without surgery. These customized trays gradually guide teeth into proper alignment without the use of brackets or wires.
Why Choose Clear Aligners?
- Nearly Invisible: Their transparent design makes them discreet.
- Removable: Unlike braces, they can be taken out for meals and oral hygiene.
- Comfortable: No metal components, reducing irritation.
- Efficient Treatment: Many users notice significant improvements within 4 to 6 months.
When Surgery Becomes Necessary
For severe Class 3 bite cases where non-surgical options are insufficient, surgical intervention may be required. Orthognathic surgery repositions the upper or lower jaw (or both) for better alignment. It is performed under general anesthesia and requires several weeks of recovery. This is typically recommended when:
- The misalignment severely affects speech or eating.
- There is extreme jaw imbalance.
- Other treatments fail to yield satisfactory results.

If you want to remedy a Class 3 bite without postoperative issues, Aligner32 Clear Aligners may be the best option. Here are some excellent reasons why so many people love them:
- Custom Fit Using Impressions: The scans or molds capture the dimensions of your teeth to provide a perfect fit to your bite or situation.

Interesting Facts About Class 3 Bite
- Approximately 5–10% of the population has some form of an underbite.
- The Habsburg jaw, a historical example of an extreme underbite, was prevalent among European royalty due to centuries of inbreeding.
- Early intervention in childhood can significantly reduce the need for corrective surgery later in life.
