How To Fix A Crossbite In Adults: A Comprehensive Guide

Having a crossbite as an adult can cause several oral health issues and aesthetic concerns. It occurs when the upper and lower teeth don’t properly align horizontally when you bite down. This misalignment can lead to problems such as difficulty in chewing, tooth wear, gum disease, and even jaw pain. If you have been struggling with a crossbite and want to correct it, this article will guide you through the various treatment options available, from non-invasive methods to surgical interventions.

What Causes Crossbite in Adults?

A crossbite can occur due to a variety of factors, and it can be a result of genetics, oral habits, or trauma. Here are a few common causes:


Some cases of crossbite are hereditary, meaning you may have inherited the misalignment from your parents or other family members.

Abnormal Jaw Growth:

If your jaw didn’t develop properly during childhood, it can lead to a crossbite. This misalignment can occur on either one side (unilateral crossbite) or both sides (bilateral crossbite) of your mouth.

Prolonged Thumb Sucking:

Thumb sucking is a common habit among young children. However, if this behavior persists beyond the ages of seven or eight, it can cause changes in the alignment of teeth, leading to a crossbite.

Untreated Baby Teeth Issues:

If you had dental problems during your childhood, such as premature loss of primary teeth or retained baby teeth, it can affect the alignment of permanent teeth, leading to a crossbite.

Treatment Options for Crossbite in Adults

Treating a crossbite in adults involves a comprehensive approach tailored to the specific needs of each individual. Here are some effective methods to fix a crossbite:

Orthodontic Treatment:

One of the most common approaches to fixing a crossbite in adults is orthodontic treatment. This method involves using braces or clear aligners to gradually shift the misaligned teeth into their proper positions. The duration of treatment may vary depending on the severity of the crossbite.

Palatal Expanders:

If the crossbite is caused by a narrow upper jaw, a palatal expander may be recommended. This device widens the upper arch by applying gentle pressure on the palate, helping to align the upper teeth properly with the lower teeth.

Maxillary Protraction Appliances:

In some cases, a crossbite may be caused by a retruded upper jaw. To correct this, a maxillary protraction appliance is used to stimulate forward growth of the upper jaw, allowing the upper teeth to align properly with the lower teeth.


In severe cases of crossbite, where orthodontic treatment alone is not sufficient, surgical intervention may be necessary. Orthognathic surgery involves repositioning the jaws to achieve proper alignment of the teeth and improve overall facial symmetry.

Choosing the Right Treatment

Consulting with an experienced orthodontist or oral surgeon is crucial in determining the most suitable treatment for your crossbite. They will conduct a thorough evaluation of your oral condition, consider your medical history, and discuss your treatment options in detail. Factors such as age, severity of the crossbite, and your personal preferences will be taken into account during the decision-making process.

It’s important to note that the earlier a crossbite is treated, the better the chances of achieving optimal results. However, thanks to the advancements in orthodontic techniques, correcting a crossbite in adults is still very much possible.

The Benefits of Fixing a Crossbite

Fixing a crossbite in adults goes beyond improving the appearance of your smile. Here are some key benefits:

Better Oral Health:

Proper alignment of teeth reduces the risk of dental problems such as cavities, gum disease, and tooth loss. An aligned bite also promotes healthier jaw joint function, reducing the likelihood of temporomandibular joint disorder (TMJ).

Improved Chewing and Speech:

A crossbite can make it difficult to chew food properly and affect speech clarity. Correcting the crossbite can enhance your ability to eat comfortably and pronounce words accurately.

Enhanced Aesthetics:

Fixing a crossbite can significantly enhance your smile and facial aesthetics, boosting your self-confidence and overall quality of life.

Q: Will fixing a crossbite require surgery?

A: Not all crossbite cases require surgery. Mild to moderate crossbites can often be corrected with orthodontic treatment alone. However, in severe cases, where skeletal discrepancies are present, orthognathic surgery may be necessary to achieve optimal results.

Q: Can a crossbite relapse after treatment?

A: With proper post-treatment care, the chances of a crossbite relapse are minimal. Following the orthodontist’s recommendations, which may include wearing a retainer, will help maintain the corrected bite alignment.

In Conclusion

Fixing a crossbite in adults is essential not only for aesthetic purposes but also for oral health and overall well-being. With the right treatment approach, such as orthodontic methods or, in severe cases, surgery, you can achieve proper bite alignment and enjoy the benefits of a healthy, confident smile. Consult with an experienced orthodontist or oral surgeon to determine the most suitable treatment for your specific crossbite condition.
