What are Crossbites in Dentistry? Understanding This Common Dental Condition
A crossbite is a type of dental misalignment that occurs when upper teeth fit inside the lower teeth when biting down. As a common orthodontic issue affecting approximately 56% of the global population, crossbites can impact both children and adults. At Blue Ocean Dentistry in Glendora, Dr. Fred Wong helps patients understand and address this condition to maintain optimal oral health.
Unlike a normal bite where upper teeth slightly overlap the lower teeth, a crossbite creates an improper relationship between the dental arches. This misalignment can affect a single tooth or multiple teeth and may lead to various complications if left untreated. Regular dental check-ups with your Glendora dentist can help identify crossbite issues early, allowing for more effective treatment.
Common Types of Crossbites and Their Characteristics
Dentists classify different types of crossbite based on which teeth are affected and the direction of misalignment. Understanding these variations helps determine the most appropriate treatment approach:
Anterior Crossbite: This occurs when the upper front teeth sit behind the lower front teeth when biting down. It’s sometimes mistaken for an underbite, but an anterior crossbite may affect just one or a few teeth rather than the entire front section.
Posterior Crossbite: Affecting the back teeth, a posterior crossbite happens when upper molars or premolars fit inside the lower ones. Research shows this type affects approximately 5-8% of children aged 3-12 years.
Unilateral Crossbite: This affects only one side of the mouth and is more common than bilateral crossbite.
Bilateral Crossbite: This less common type affects both sides of the mouth and often requires more comprehensive treatment.
Knowing the different types of crossbite helps your dentist develop a targeted treatment plan for your specific condition.
What Causes Crossbites? Understanding the Root Factors
Understanding what causes a crossbite can help parents take preventive measures for their children. Several factors may contribute to the development of this dental condition:
- Genetic Factors: Family history plays a significant role in dental development. If parents have had crossbite issues, children may be more likely to develop them as well.
- Delayed Loss of Primary Teeth: When baby teeth remain in place too long, permanent teeth may emerge in improper positions.
- Abnormal Tooth Eruption Patterns: Sometimes permanent teeth simply come in at unusual angles or positions.
- Oral Habits: Prolonged thumb-sucking, pacifier use, or abnormal swallowing patterns can influence jaw development.
- Respiratory Issues: Chronic mouth breathing due to allergies or enlarged tonsils may affect jaw growth.
- Jaw Size Discrepancies: Sometimes the upper and lower jaws develop at different rates or to different sizes.
Genetics is one of the primary factors in what causes a crossbite to develop, but environmental factors also play an important role. Early dental intervention can often address these issues before they become more serious.
How Crossbites Teeth Affect Your Oral Health
Crossbites can cause uneven wear on your tooth enamel over time. This irregular wear pattern may lead to several oral health complications that extend beyond mere cosmetic concerns:
- Uneven Tooth Wear: When teeth don’t align properly, certain teeth bear more pressure than others, leading to premature wear and potential damage.
- Gum Recession: Misaligned teeth can put excessive pressure on the gums, causing them to recede and potentially exposing sensitive tooth roots.
- Difficulty Maintaining Oral Hygiene: Cross bite teeth often create tight spaces or overlaps that make proper brushing and flossing challenging, increasing the risk of tooth decay and gum disease.
- Chewing Difficulties: A crossbite can make it uncomfortable to chew certain foods, potentially affecting nutrition and enjoyment of meals.
- Speech Issues: Some patients with crossbites may develop speech impediments or difficulties pronouncing certain sounds.
Many patients don’t realize they have cross bite teeth until a dentist identifies the condition during a routine examination. This highlights the importance of regular dental check-ups for maintaining optimal oral health.
Complications of Severe Crossbites When Left Untreated
Left untreated, severe crossbite can lead to significant jaw pain and TMJ disorders. The long-term consequences may include:
- Temporomandibular Joint (TMJ) Disorders: The jaw joints may become strained from compensating for misaligned teeth, leading to pain, clicking, or limited jaw movement.
- Facial Asymmetry: Over time, the jaw may grow unevenly to accommodate the crossbite, resulting in visible facial asymmetry.
- Chronic Headaches: The strain from improper bite alignment can cause recurring headaches and neck pain.
- Accelerated Tooth Damage: Severe crossbite cases often result in more rapid tooth wear, fractures, or chips.
- Psychological Impact: A crossbite smile can affect not only your appearance but also your confidence in social situations, potentially leading to self-esteem issues.
- Severe crossbite cases often require more comprehensive treatment approaches, but the good news is that modern dentistry offers effective solutions for patients of all ages.
How to Fix Crossbites: Treatment Options Explained
Learning how to fix a crossbite starts with a comprehensive dental evaluation. When considering how to fix a crossbite, your dentist will assess the severity and type of misalignment. Treatment options vary based on age, severity, and the specific type of crossbite:
Braces for Crossbites: Traditional Treatment Approach
Traditional braces for crossbite remain one of the most effective treatment options. These appliances work by applying consistent pressure to gradually move teeth into proper alignment. The length of time you’ll need to wear braces for crossbite correction depends on the severity of your condition, typically ranging from 18 to 36 months.
Modern braces are more comfortable and less noticeable than older versions, with options including tooth-colored ceramic brackets that blend with your natural teeth.
Does Invisalign Fix Crossbites? Exploring Clear Aligner Options
Many patients ask: does Invisalign fix crossbite as effectively as traditional braces? While does Invisalign fix crossbite is a common question, the answer depends on the severity and type of your crossbite.
For mild to moderate cases, particularly anterior crossbites, Invisalign can be highly effective. Clinical studies have shown significant improvements in:
- Labial movement of maxillary incisors
- Arch perimeter
- Intermolar width
However, more complex or severe crossbites might still require traditional orthodontic approaches. Your Glendora dentist can evaluate your specific case to determine if clear aligners are appropriate for your needs.

Modern cross bite treatment options are more comfortable and effective than ever before. At Blue Ocean Dentistry, Dr. Wong provides personalized care for patients with crossbite issues:
- Initial Consultation: A thorough examination including digital imaging to assess the exact nature of your crossbite.

- Retention Phase: After active treatment, retainers help maintain your new smile.
- The ideal cross bite treatment plan will be customized to your specific needs and lifestyle. For children, early intervention often yields the best results, while adults may require more comprehensive approaches.
Prevention and Early Detection
While some crossbite issues are genetic and cannot be prevented, early detection can make treatment simpler and more effective. Parents should:
- Schedule a child’s first dental visit by age one
- Have regular dental check-ups every six months
- Address prolonged thumb-sucking or pacifier use
- Consult with a dentist if baby teeth are lost prematurely or retained too long
Many parents wonder: can crossbite fix itself as a child grows? Unfortunately, this rarely happens without intervention. Professional dental crossbite treatment is typically necessary to correct the misalignment.
Maintaining Oral Health During Crossbite Treatment
Proper oral hygiene is especially important during crossbite treatment. Whether you’re using braces, aligners, or other appliances, maintaining good dental habits helps ensure the best possible outcome:
- Brush thoroughly at least twice daily with fluoride toothpaste
- Floss daily, using special tools if necessary for braces
- Use antimicrobial mouth rinses if recommended by your dentist
- Attend all scheduled adjustment appointments
- Follow your dentist’s specific care instructions
These practices help prevent tooth decay and gum disease during treatment, ensuring your smile is both straight and healthy when treatment concludes.
