How to Fix an Overbite | Clear Aligner Treatment Guide

A small overbite might not seem like a big deal at first, but in many cases it can affect more than just the appearance of your smile.

If you’ve found yourself searching “how to fix an overbite”, you’re not alone. Overbites are one of the most common dental alignment issues, and modern orthodontic treatments — including clear aligners — can often correct them effectively.

Let’s break down what an overbite actually is and how it can be treated.

What Is an Overbite?

An overbite occurs when the upper front teeth overlap the lower front teeth more than they should.

In dentistry, this type of misalignment is known as a malocclusion, which simply means the bite does not align properly.

A small amount of overlap is normal, but when the overlap becomes too large it can lead to additional problems such as:

• Jaw discomfort or pain

• Headaches

• Tooth wear or erosion

• Difficulty chewing

• Speech issues

• Increased risk of cavities or gum disease

The severity of an overbite can vary from mild to more complex cases.

Types of Overbites

There are generally two main types of overbites.

Skeletal Overbite

A skeletal overbite is typically caused by the size or position of the jawbones. This type is often influenced by genetics and the way the jaw develops during growth.

Dental Overbite

A dental overbite occurs when the teeth themselves are misaligned, even if the jaw structure is normal.

This type can develop due to childhood habits such as:

• Thumb sucking

• Prolonged pacifier use

• Tongue thrusting

• Bite development issues

How Overbites Are Measured

Dental professionals measure the overlap between the upper and lower front teeth to determine severity.

Typical measurements include:

• Normal Overbite: 1–3 mm

• Deep Bite: 4–8 mm

• Severe Overbite: 9 mm or more

These measurements help determine which treatment approach is most suitable and how long correction may take.

What Causes an Overbite?

Several factors can contribute to developing an overbite.

Genetics

In many cases, jaw size and shape are inherited, which can influence how the teeth align.

Childhood Habits

Habits during early development can affect how the teeth and jaw grow. Examples include thumb sucking or prolonged pacifier use.

Missing or Crowded Teeth

Losing teeth or having crowded teeth can allow surrounding teeth to shift into incorrect positions, affecting overall bite alignment.

Poor Oral Habits

Certain habits may also contribute to bite issues over time, such as:

• Teeth grinding

• Nail biting

• Chewing on pens or hard objects

Can Clear Aligners Fix an Overbite?

In many cases, clear aligners can successfully treat mild to moderate overbites.

Clear aligners work by applying controlled, gradual pressure to guide teeth into better alignment over time.

Each aligner tray is designed to move teeth in small, precise increments, allowing the jaw and surrounding bone to adapt safely as the teeth shift.

This process works through natural bone remodelling:

• Pressure is applied to the tooth

• The periodontal ligament (PDL) compresses

• Bone gradually remodels to support the new tooth position

The Aalto Clear Aligner Approach

Aalto clear aligners are designed using advanced digital treatment planning and high-quality materials.

Our aligners are made from Zendura FLX, a durable and flexible material known for:

• High clarity for a discreet appearance

• Comfortable wear

• Strong elasticity that maintains consistent force

Treatment begins with an in-office assessment at an Aalto partner clinic, where a treating dentist will:

• Assess your bite and alignment

• Take a detailed digital scan of your teeth

• Determine whether aligners are suitable for your case

From there, a custom treatment plan is created to guide your teeth step by step into their ideal position.

Treatment Time and Cost

Clear aligner treatment timelines vary depending on the complexity of the case.

For many patients, treatment may take between 6 and 12 months, although some cases may be shorter or longer.

Clear aligners are also often more affordable than traditional orthodontic options, and many providers offer flexible payment plans to make treatment accessible.

Your exact treatment timeline and cost will be discussed after your initial assessment, once your personalised treatment plan has been created.
