Cross Bite

What is a Crossbite?

A cross-bite occurs when some of the upper teeth sit inside the lower teeth when the mouth is closed. This misalignment can affect a single tooth or a group of teeth and can lead to uneven wear, gum disease, or bone loss. Cross-bites can also cause jaw problems and asymmetry.

Treatment options include braces, clear aligners, or palatal expanders, depending on the severity and the age of the patient, aiming to achieve a proper alignment of the upper and lower teeth.

FAQs

How do you fix a crossbite?

A crossbite can be corrected using various orthodontic treatments, such as braces, clear aligners like Invisalign, palatal expanders, and in some severe cases, orthognathic surgery. The treatment depends on the crossbite type and whether it involves teeth, the jaw, or both.

What does it mean to have a crossbite?

Having a crossbite means that when the mouth is closed, some upper teeth sit inside the lower teeth rather than outside, occurring at the front (anterior) or sides (posterior) and can affect a single tooth or multiple teeth.

What happens if a crossbite is left untreated?

If left untreated, a crossbite can lead to uneven wear on teeth, increased risk of tooth decay and gum disease, jaw pain, TMJ disorders, and negatively impact jaw growth in children.

How do you treat a single crossbite?

A single tooth crossbite can often be corrected with braces or Invisalign, moving the tooth into the correct position. Sometimes, a removable appliance or a fixed expander might be used.

Is it worth fixing a crossbite?

Yes, fixing a crossbite improves oral function, prevents dental problems, and enhances aesthetic appearance, helping to avoid jaw pain, TMJ disorders, and uneven wear on teeth.

What is the best age to fix a crossbite?

The best age is during childhood or adolescence when the jaw is still growing, guiding the jaw's growth correctly and often reducing the need for more invasive treatments later. However, adults can still be treated effectively.

Can you fix crossbite as an adult?

Yes, crossbites can be fixed in adults using braces, Invisalign, palatal expanders, or surgery, depending on severity. Treatment may take longer and sometimes requires surgery but can achieve significant improvements.

Does fixing a crossbite change your jaw?

Fixing a crossbite can lead to changes in jaw alignment, especially if treatment includes appliances that modify jaw growth or orthognathic surgery, aiming for a proper bite and balanced facial aesthetics.

Does fixing crossbite change face shape?

Correcting a crossbite can slightly change face shape, particularly if it involves adjusting the jaw's position. Changes are subtle but can lead to a more harmonious facial balance and profile.

How long does it take to treat a crossbite?

Treatment duration varies depending on the method and severity, ranging from several months to a few years. Children and adolescents may see quicker treatment times, while adults might have longer periods.
