What is an Open Bite

An open bite, sometimes referred to as an anterior open bite, is a type of malocclusion where the upper and lower teeth don't make contact when the mouth is closed, leaving a visible gap. You might notice it most when biting into food, where the front teeth simply don't meet.
While a mild open bite is often purely cosmetic, a more pronounced open bite can affect your ability to bite and chew properly, impact your speech, and place uneven stress on the back teeth over time.

Types of Open Bite

Anterior Open Bite

The most common type - where the front teeth don't make contact when the mouth is closed, leaving a visible gap between the upper and lower teeth. The back teeth may still meet normally. This is the type most commonly associated with childhood habits like thumb sucking.

Posterior Open Bite

Where the back teeth don't make contact when biting, while the front teeth do meet. This is less common than an anterior open bite and can affect chewing efficiency significantly as the molars are responsible for the majority of bite force.

Aligners are suitable for mild open bites only. Take our quiz to help find out whether you may be suitable for clear aligners.

What Causes an Open Bite?

Genetics

The shape and growth pattern of the jaw is largely inherited. Some people naturally develop a jaw structure where the back teeth meet but the front teeth don't - regardless of any childhood habits.

Childhood Habits

Prolonged thumb sucking, dummy use, or tongue thrusting during childhood are the most common causes of an open bite. These habits place consistent pressure on the front teeth, gradually pushing them apart and preventing them from meeting.

Mouth breathing

Chronic mouth breathing - often linked to allergies, enlarged tonsils, or a deviated septum can affect how the jaw and palate develop in childhood, contributing to an open bite forming over time.

Tongue thrusting

When the tongue habitually pushes forward against the front teeth at rest or when swallowing, it places ongoing pressure that prevents the teeth from closing together properly.

Skeletal growth issues

In some cases, the upper and lower jaws grow at different vertical rates during development, causing the bite to open rather than close properly. This type of open bite is structural rather than dental and can be more complex to treat.

Reasons for open bite treatment

Here's Why You Should Treat an Open Bite

Difficulty biting or chewing

When the front teeth don't meet, everyday tasks like biting into food become difficult or inefficient — placing extra strain on the back teeth to compensate.

Uneven Tooth Wear

The back teeth taking on excessive bite force leads to accelerated and uneven enamel wear, which over time can cause sensitivity, chipping, and structural damage.

Worsens over time

Unlike some dental concerns that remain stable, an open bite can gradually worsen - particularly if the underlying habit like tongue thrusting continues alongside it.

Back tooth strain

When the front teeth can't share the load of biting, the back molars absorb disproportionate force — accelerating wear and increasing the risk of cracking or sensitivity.

Self-confidence

A visible gap between the front teeth when the mouth is closed or at rest is one of the more noticeable bite issues, often affecting how people feel about their smile and appearance.

Speech & function

An open bite is one of the most common bite-related causes of speech difficulties, particularly affecting sounds like "s", "z", and "th" - often causing a lisp.
