What is a Crossbite? 

In the world of dental health, various issues can arise that demand our attention. Among these concerns, crossbites stand as a common yet often misunderstood problem. If you’ve ever wondered, “What is a crossbite?” you’re not alone. In this comprehensive guide, our Raleigh area dentist aims to demystify this dental condition, shedding light on its definition, causes, and potential consequences.

Understanding Crossbites

A crossbite is a common dental misalignment issue characterized by an improper alignment of the top teeth and lower teeth when the jaw is closed. Unlike a normal bite where the upper teeth slightly overlap the lower teeth, a crossbite results when the upper teeth sit inside or outside the lower teeth when the upper jaw and lower jaw are brought together. This misalignment can affect one or multiple teeth, leading to various types of crossbites.

Anterior Crossbite

An anterior crossbite occurs when the upper front teeth are positioned behind the lower front teeth when the jaws are closed. This can affect one single tooth or more of the upper incisors.

Posterior Crossbite

A posterior crossbite involves the back teeth. In this case, the upper back teeth, or molars, are positioned inside the lower molars when the mouth is closed. Posterior crossbites can affect a single tooth or teeth both sides of the mouth.

Unilateral Crossbite

Unilateral crossbites affect only one side of the mouth. This misalignment can involve one or more teeth on the upper or lower jaw, creating an asymmetrical bite.

Bilateral Crossbite

Bilateral crossbites affect both sides of the mouth and typically involve multiple teeth on both the upper and lower jaws. Upper teeth fit inside the bottom teeth on both sides, making this type of crossbite particularly challenging.

What Causes a Crossbite?

A crossbite is a dental misalignment issue that can develop due to a combination of genetic, environmental, and behavioral factors. Understanding these causes can help individuals and parents take proactive steps to prevent or address crossbites.

Family History

One of the primary risk factors for crossbites is genetics. If parents or close family members have a history of dental misalignments, including crossbites, there is an increased likelihood that their children may inherit similar dental issues. Genetic factors can influence the size and shape of the jaw, as well as the alignment of teeth.

Oral Habits

Prolonged thumb sucking, pacifier use, or the use of other oral habits during childhood can put pressure on the developing teeth and jaw. This constant pressure can disrupt the natural alignment of teeth and contribute to the development of crossbites.

Additionally, habitual tongue thrusting, where the tongue pushes against the front teeth during swallowing or speaking, can also affect the positioning of teeth and jaws over time, leading to crossbites.

Tooth Eruption and Growth

When adult teeth do not erupt in the correct order or at the expected time, it can disrupt the alignment of neighboring teeth. Late-emerging permanent teeth may lead to jaw shifting and crossbite development.

Also, insufficient space in the dental arch can cause teeth to shift and become misaligned, potentially resulting in a crossbite.

Injury or Trauma

Trauma to the face or jaw can alter the natural alignment of teeth and jaws, causing a crossbite. Such injuries can occur from accidents, falls, or sports-related incidents.

Breathing Habits

Chronic mouth breathing instead of nasal breathing can influence the growth and positioning of the upper and lower jaws. Over time, this can contribute to crossbite development.

Early Tooth Extractions

Premature removal of primary (baby) teeth or permanent teeth can affect the alignment of surrounding teeth, potentially leading to crossbites.

Lack of Early Intervention

Failure to address dental misalignments in childhood through orthodontic treatments can allow crossbites to worsen over time.

What Are the Risks if a Crossbite Goes Untreated?

A crossbite, as we’ve discussed, is a dental misalignment that occurs when the upper and lower teeth do not meet correctly when the jaws are closed. While it might seem like a minor concern, leaving a crossbite untreated can lead to various oral health issues and potentially affect your overall well-being.

Dental Problems

One of the most immediate consequences of a crossbite is uneven tooth wear. When upper and lower teeth don’t align properly, certain teeth may experience more pressure during biting and chewing. Over time, this uneven wear can lead to dental erosion, cavities, and a compromised tooth structure.

As enamel wears away due to the misalignment, teeth can become more sensitive to hot and cold temperatures, leading to discomfort. The constant pressure on the gums caused by a crossbite can lead to gum recession, exposing tooth roots and making them susceptible to decay and sensitivity.

Jaw and Facial Pain

Untreated crossbites can contribute to TMJ disorders, causing jaw pain, clicking or popping sounds in the jaw joint, headaches, and facial discomfort. The improper alignment of the teeth in a crossbite can lead to overuse and strain of the jaw muscles, resulting in chronic pain in the face, neck, and shoulders.

Speech and Communication Difficulties

Crossbites can affect the way you pronounce certain sounds and words, leading to speech difficulties and potential self-esteem issues.

Self-Esteem and Psychological Impact

Crossbites can alter the appearance of your smile, which may impact your self-confidence and self-esteem. This psychological aspect is particularly significant, especially for adolescents and adults.

Treatment Options for Crossbites

The choice of treatment depends on the severity of the crossbite, patient age, and individual preferences, but two of the most notable treatment plan options are traditional metal braces treatment or Invasalign clear aligners.

Traditional Braces

Traditional metal braces are a highly effective method for correcting crossbites. They involve attaching brackets to the teeth and connecting them with wires that are periodically adjusted by an orthodontist to move the teeth into their correct positions. This method is particularly useful for severe crossbites and complex cases.

Invisalign

Invisalign is an alternative to traditional braces that uses clear, removable aligners to gradually shift the teeth into proper alignment. It is a popular choice among those seeking a more discreet and convenient option for crossbite correction.

Effectiveness of Invisalign in Correcting Crossbites

Invisalign, the innovative clear aligner system, has revolutionized orthodontic treatment by offering a discreet and convenient alternative to traditional braces. But can Invisalign effectively correct crossbites, a common dental misalignment issue? The answer is a resounding yes. Invisalign has proven to be highly effective in treating various types of crossbites, providing patients with both functional and aesthetic benefits.

Precise Treatment Planning

Invisalign treatment begins with a detailed digital scan or impression of your teeth. This data is used to create a 3D model of your mouth, allowing the orthodontist to plan a precise treatment strategy. Advanced computer algorithms then generate a series of clear aligners that are custom-made to gradually shift your teeth into their correct positions, including correcting crossbites.

Targeted Force Application

Each set of Invisalign aligners is specifically designed to exert controlled pressure on specific teeth to move them into proper alignment. For crossbites, these aligners are strategically engineered to address the misaligned teeth and jaw position.

Comfortable and Discreet

One of the primary advantages of Invisalign is its comfort and discreet appearance. The aligners are made of smooth, BPA-free plastic, making them more comfortable than traditional braces. Moreover, they are virtually invisible, allowing you to undergo treatment without the noticeable appearance of metal wires and brackets.

Improved Oral Hygiene

Invisalign aligners are removable, making it easy to maintain proper oral hygiene. Unlike traditional braces, which can make brushing and flossing challenging, you can simply remove your aligners to clean your teeth thoroughly. This reduces the risk of plaque buildup and tooth decay during treatment.

Reduced Treatment Time

The duration of Invisalign treatment is typically the same as traditional braces for correcting crossbites. In some cases, it may even be faster due to the precision of the aligners and the ability to control tooth movements more accurately.

Predictable Results

Invisalign’s digital treatment planning allows for highly predictable results. Patients can see the virtual outcome of their treatment before it even begins, giving them a clear understanding of the expected results and progress throughout the treatment process.

Comfortable Progression

With Invisalign, you’ll receive a series of aligners to be worn sequentially, each one slightly adjusted to continue the progress of tooth movement. This gradual and comfortable progression helps minimize discomfort typically associated with adjustments in traditional braces.
