What is a crossbite? Characteristics, causes, and method treatment

Crossbite is a common form of bite deviation, not only affecting the aesthetics of the smile but also reducing the ability to chew. Therefore, early recognition and treatment of crossbite teeth is essential to promptly prevent long-term harm and complications. Let’s learn more about this condition with Elite Dental in the following article!

1. What is a crossbite?

Crossbite is a condition in which the teeth on the jaw are divided into many groups that protrude outward or inward, disrupting the symmetry between the two jaws. In many cases, mild bite misalignment does not appear clearly on the face but still makes the patient’s smile appear unnatural and less bright.

The misaligned bite causes a loss of aesthetics when smiling and has many effects on oral health.

The case of a rather severe crossbite causing facial misalignment was well-overcome thanks to orthodontic techniques, moving the teeth and bite.

2. Characteristics of identifying crossbite

Based on the deviation characteristics, crossbite teeth are divided into 2 main types:

  • Crossbite of front teeth (accounts for 4-5% of the population): When the jaw is closed, one or more upper teeth will appear to grow inward compared to the lower teeth.
  • Posterior crossbite (accounts for 16% of the population): One or a group of upper teeth grow inward, on the side that is deviated from the lower jaw.

With such an unusual growth direction, the teeth are skewed diagonally, causing the upper and lower jaws to not match properly or harmoniously in terms of tooth position and interdental spaces. At the same time, the line between the front teeth of the two jaws is also misaligned and linked, causing a mismatch in the aesthetics of the entire mouth and many dangerous oral diseases such as periodontal disease, joint pain, tooth loss, etc. 

3. What is the reason for crossbite?

There are main causes of crossbite, specifically:

  • Due to genetics: If parents, grandparents, or relatives have crossed teeth, it is likely that their children, grandchildren, and family members will also have the same condition.
  • Due to abnormal growth of permanent teeth, baby teeth do not fall out, causing permanent teeth to grow behind, and in the wrong position.
  • Due to abnormal jaw bone development, such as an underdeveloped upper jaw or overdeveloped lower jaw.
  • Due to bad habits such as biting the upper lip, sucking fingers, pushing the tongue, lazy chewing, and using milk bottles or nipples for long periods of time.

4. Is crossbite dangerous?

Teeth that are crooked diagonally cause a loss of facial harmony and aesthetics, and can especially cause the face to be distorted and the chin to be misaligned. In addition, people with crooked teeth have a reduced ability to chew and bite food, thereby affecting the digestive process and making them susceptible to stomach diseases.

Not only that, cleaning crossbite teeth is also very difficult, increasing the possibility of tooth decay, gingivitis, or periodontal disease. More specifically, we cannot be subjective with severe crossbite complications that pose a potential risk of temporomandibular disorder, causing pain in the head, shoulders, and neck and limiting the function of the jaws.

Misaligned bite increases the risk of oral diseases such as gingivitis, periodontal disease, and tooth decay because cleaning is quite difficult.

Misaligned bite also causes periodontal disease and a high possibility of early tooth loss. Therefore, when braces are applied, the teeth are rearranged into the correct position, which will help repel periodontal disease and improve oral health.

5. When is it most appropriate to correct crossbite?

To prevent the above-mentioned harmful effects, each person should proactively examine and adjust their bite as soon as possible. It is best for children aged 6-12 years old. Because this is the time when children begin to change teeth and the jawbone is in the process of developing, treatment to correct misaligned teeth will be easier and more effective. In addition, when the growing teeth are not yet complete, with the help of appropriate orthodontic appliances at this stage, it is possible to arrange, orient, and create space for the teeth to grow in the correct position, promptly overcoming the problem. permanent teeth grow crookedly, crooked teeth cause a misaligned bite. Therefore, as soon as parents discover that their child has signs of crooked teeth, they should quickly take the child to a reputable dentist for examination. Or it is best when the child is 6-7 years old to visit an orthodontist to examine the condition of teeth and jawbone, abnormalities will be clearly evident.

For adults, crossbites can be completely corrected with appropriate methods and monitoring by an orthodontist with specialized orthodontic knowledge, expertise and experience.

6. How many methods are there to treat crossbites?

Crossbite treatment helps restore chewing function, brings aesthetic effects, and helps maintain good oral health. Currently, there are two commonly used methods of correcting crossbite:

6.1. Braces correct crossbite

Braces are a solution to help you have straight teeth, a standard bite and a radiant smile. Currently, there are 2 methods of braces:

  • Braces: This is a traditional orthodontic method that uses a set of appliances including shaped wires and metal or ceramic brackets to create a force to continuously move teeth to the standard position on the jaw. Although this method has an average cost and good effectiveness, it has poor aesthetics, as well as the potential risk of causing irritation and creating a feeling of entanglement and inconvenience for the patient.

  • Invisalign transparent braces: Superior to the braces method, Invisalign braces use transparent braces made from high-quality materials, individually designed with the ability to hug the teeth. Thanks to that, it not only creates optimal tooth movement efficiency but also has high aesthetics, as well as being easy to remove for cleaning and eating.

6.2. Crossbite orthopedic surgery

If the degree of crossbite misalignment is severe, mainly due to misaligned bones, it needs to be treated with orthopedic surgery to adjust the jaw structure and move it to the correct bite position. This method requires a lot of recovery time and can cause complications (such as heavy bleeding, infection, etc.), more specifically, it is quite expensive and can easily cause fear in the patient.

Usually, braces can correct crossbites well. Therefore, if you have a crossbite defect, consult an orthodontist for a chance to change your smile to a healthy and confident one. Depending on the condition and level of specific crossbite teeth, appropriate correction methods need to be applied. At the same time, to achieve high treatment efficiency and ensure safety, you need to choose a reputable dental clinic with a team of highly qualified and experienced doctors to help come up with a treatment plan.
