Types of Open Bite

What is an open bite?

Normally, the top teeth should slightly overlap the bottom teeth. But in an open bite, some of your teeth don’t touch at all, leaving a gap between them. This can happen in the front of your mouth or in the back, and it can make it hard to chew food or even affect how you talk.

Types of open bites

Open bites can be classified into different types based on where the gap occurs and what causes it.

Anterior open bites involve the front teeth not touching, while posterior open bites occur when the back teeth don’t meet.

Some open bites are caused by jawbone issues, known as skeletal open bites, while others are due to misaligned teeth, referred to as dental open bites.

Anterior Open Bite

An anterior open bite happens when your front teeth don’t touch even when your mouth is fully closed. This can make it hard to bite into food or say certain words clearly.

Basic charactistic of this dental issue are your front teeth do not touch and have an opening when the back teeth are closed.

Causes

• Thumb-sucking or prolonged pacifier use.
• Tongue thrusting habits.
• Skeletal abnormalities or genetic factors.

This type of bite issue is most common in children and individuals with persistent oral habits.

Posterior Open Bite

A posterior open bite happens when your back teeth don’t touch when you close your mouth, leaving a gap.

This can make it hard to chew food properly because the back teeth aren’t working together. It can be caused by missing teeth, the way your teeth grew in, or using certain orthodontic devices for too long.

Causes

• Missing molars or dental arch discrepancies.
• Prolonged use of certain orthodontic appliances.

This condition is most common in adults or those with untreated dental conditions.

Skeletal Open Bite

A skeletal open bite happens because of the way your jawbones grow, not just your teeth. It can cause gaps between your upper and lower teeth, even when your mouth is closed.

This type of open bite often runs in families and might need jaw surgery to fix if it’s severe.

Causes

• Improper eruption of teeth.
• Tooth crowding or spacing.

This skeletal problem is most common in children and adults with poor dental development.

Dental Open Bite

A dental open bite happens when some of your permanent teeth don’t line up properly, leaving a gap when you close your mouth.

This can happen if your teeth don’t grow in the right way or if there’s crowding or spacing between them. It’s usually not caused by your jaw but just by the way your teeth are positioned.

Causes

• Improper eruption of teeth.
• Tooth crowding or spacing.

Dental open bite problems are common in children and adults with poor dental development.

Diagnoising an open bite?

Orthodontists like Dr. Dallam use a few steps to figure out if you have an open bite:

Step one: Looking at Your Teeth

• They will check your teeth alignment and bite by asking you to close your mouth.
• They’ll look for gaps where your teeth don’t touch.

Step two: Taking X-rays or Pictures

• They might take special pictures or X-rays of your teeth and jaw.
• These images help them see if the problem is with your teeth or the bones in your jaw.

Step three: Asking About Your Habits

• They’ll ask if you’ve had habits like thumb-sucking, using a pacifier, or pushing your tongue against your teeth.
• This helps them understand what might have caused the open bite.

Step four: Measuring Your Bite

• They may use tools to measure how your teeth fit together and how your jaw moves.
• This helps them decide the best way to fix the problem.

Using all this information, your orthodontist can determine the type of open bite you have and how to treat it.

Treatment of Open Bites

There are several ways to fix an open bite, depending on what caused it.

If habits like thumb-sucking or tongue thrusting are the problem, therapy and behavior modificationcan help stop those habits.

If the lack of contact between your teeth is dental in nature, the most common type of fix is with orthodontic treatment.

Braces or clear aligners can move your teeth into the right position for many cases of open bite. For more serious problems, like those caused by the shape of your jaw, surgery might be needed to correct the issue. The earlier an open bite is treated, the easier it is to fix!
