Deep overbite

What causes a deep overbite?

A deep overbite usually comes from a mix of jaw (skeletal) and tooth (dental) factors, such as:

• Uneven jaw growth, especially a short lower jaw
• Crowded or misaligned teeth
• Oral habits in early childhood
• Losing back teeth (in adults), which changes how the bite comes together

In children and teens who are still growing, an overbite may get deeper over time without orthodontic treatment.

How do I know if my child has a deep overbite?

You or your child may have a deep overbite if:

• The lower front teeth disappear behind the upper front teeth when biting down
• The lower teeth touch the roof of the mouth
• The lower front teeth look noticeably worn
• The chin looks set back or “tucked in”
• The jaw feels sore or tight, or it pops

Some people also have speech changes or trouble biting into foods like sandwiches or apples.

Why does a deep overbite need treatment?

Without treatment, a deep overbite can lead to:

• Gum damage and injury to the roof of the mouth
• Early wear or chipping of the lower teeth
• Jaw strain, headaches, or TMJ problems
• Bone loss or receding gums over time

Braces and other orthodontic appliances can help correct an overbite. They bring the bite into line, help the teeth work together, and protect the teeth and gums.

How do you fix a deep overbite?

Treatment options may include:

• Braces with rubber bands to realign the bite
• Bite turbos or other appliances that hold the teeth slightly apart while the bite is corrected
• Removing a tooth, in rare and severe cases
• Clear aligners, when they suit the case

For younger children, early orthodontic checkups can help keep a bite problem from becoming as severe and make treatment simpler later.

When should my child see an orthodontist?

If your child’s lower teeth bite into the roof of their mouth, or their upper front teeth seem to hide the bottom row completely, it’s time to schedule an orthodontic consultation.

At Families First, we offer free consultations that include imaging and treatment recommendations from our orthodontic team. You can also read about the different types of braces that can help correct a deep overbite.
