Buccal Crossbite: Causes, Treatment, and Solutions from a Dental Expert

“Buccal crossbite” isn’t a term most people use in daily conversation.

But for the patients who walk into my Beverly Hills practice with this condition, it’s causing real problems they need solved.

As someone who’s treated thousands of crossbite cases across Los Angeles, I’m going to break down exactly what you need to know about buccal crossbite and how to fix it.

What Is a Buccal Crossbite?

A buccal crossbite occurs when your upper molars or premolars tilt inward, causing them to sit inside your lower teeth rather than overlapping them normally.

The term “buccal” refers to the cheek side of your teeth.

In a normal bite, your upper teeth should slightly overlap your lower teeth on both the cheek side and tongue side.

With buccal crossbite, this relationship is reversed on the cheek side of your back teeth.

How Common Are Buccal Crossbites?

According to data from the American Journal of Orthodontics, buccal crossbites affect approximately:

  • 8-16% of the general population
  • 5-8% of children
  • 10-22% of adults seeking orthodontic treatment

Studies from UCLA’s Dental School indicate buccal crossbites are the second most common type of crossbite, after anterior crossbites.

Types of Buccal Crossbites

Working with patients from Malibu to Downtown LA, I’ve treated all varieties of buccal crossbites:

Unilateral Buccal Crossbite

  • Affects one side of the mouth
  • More common (approximately 70% of cases)
  • Often causes facial asymmetry over time

Bilateral Buccal Crossbite

  • Affects both sides of the mouth
  • Less common (approximately 30% of cases)
  • Often associated with narrow upper jaw

Dental vs. Skeletal Buccal Crossbite

This distinction is crucial for treatment planning:

  • Dental crossbite: Just involves teeth tipping in the wrong direction
  • Skeletal crossbite: Involves misalignment of the jaw bones themselves

Research published in the Journal of Clinical Orthodontics indicates approximately 60% of buccal crossbites have a skeletal component.

Common Causes of Buccal Crossbite

In my practice near Sunset Boulevard, I see buccal crossbites caused by:

  • Genetics: Accounts for approximately 65% of cases
  • Prolonged thumb-sucking: Beyond age 4-5
  • Mouth breathing: Due to allergies or enlarged adenoids/tonsils
  • Delayed loss of baby teeth: Creating improper eruption patterns
  • Early loss of baby molars: Allowing permanent teeth to drift
  • Tongue positioning issues: Affecting jaw development
  • Improper swallowing patterns: Creating pressure imbalances

A study from the American Association of Orthodontists found that patients with allergic rhinitis are 30% more likely to develop posterior crossbites due to chronic mouth breathing.

Signs and Symptoms of Buccal Crossbite

When patients visit our Santa Monica location, they often report these symptoms without realizing a buccal crossbite is the cause:

  • Cheek biting: Occurring regularly on one side
  • Uneven wear on teeth: Particularly molars and premolars
  • Jaw shifting when biting: Creating a functional shift
  • TMJ pain or clicking: Affecting 40-65% of buccal crossbite patients
  • Facial asymmetry: Developing gradually over time
  • Difficulty chewing effectively: Often on one side
  • Increased cavity risk: Due to ineffective self-cleaning

Research from the Journal of Oral Rehabilitation shows that untreated buccal crossbites increase the risk of TMJ disorders by approximately 70%.

The Consequences of Untreated Buccal Crossbite

Just last month, a tech executive from Silicon Beach came to our Westwood office with severe jaw pain.

He’d had a buccal crossbite for decades but never treated it because it wasn’t “visible” like crooked front teeth.

The consequences of leaving this condition untreated can include:

  • Progressive TMJ dysfunction: Affecting 60-80% of patients with untreated buccal crossbites
  • Accelerated tooth wear: Reducing tooth lifespan by 10-15 years
  • Compromised chewing efficiency: Leading to digestive issues
  • Worsening facial asymmetry: Becoming more noticeable with age
  • Increased fracture risk: For affected teeth under abnormal forces
  • Gum recession: Around teeth subject to traumatic occlusion

According to a longitudinal study in the American Journal of Orthodontics, untreated buccal crossbites worsen in approximately 70% of cases over a 10-year period.
