Jaw misalignments are commonly inherited conditions, but a few habits can cause or exacerbate them, including thumb-sucking, prolonged bottle feeding, and nail-biting. Tongue thrusting can also push the teeth and jaw out of position by applying consistent pressure behind the top row of teeth. Fortunately, a dentist or orthodontist can resolve most cases of jaw misalignment, and it’s common to treat these conditions during childhood. 

3 Types of Jaw Misalignments

Overbite

Overbites are the most common form of malocclusion or imperfect bite alignment. Most people have around 3 to 5 millimeters (mm) between their top and bottom teeth. If your child has more space between those rows, they could develop symptoms such as difficulty chewing and headaches. Over time, an overbite can also produce extra wear on the temporomandibular joint. 

Underbite

An underbite is the opposite of an overbite; the lower row of teeth protrude beyond the top row. People with an underbite can experience the same symptoms as an overbite with increased severity; they might also experience ear pain, a higher risk of tooth decay, muscle strain, and premature enamel wear. Over time, they’re more likely to develop arthritis and temporomandibular joint syndrome (TMJ). 

Crossbite

A lateral misalignment characterizes a crossbite; one side of the jaw is slightly off-center. Although unhealthy habits can worsen the condition, it’s common for crossbites to be hereditary. If one or several teeth are tilted, which is usually an inherited trait, it can interfere with how the top and bottom teeth naturally fit together. Someone with a crossbite has a greater risk of developing gum disease and pain in their jaw, neck, and shoulders. They might also develop facial features that are slightly asymmetrical. 

How Are Overbites, Underbites, and Crossbites Treated? 

Braces and a jaw retainer can be used to treat most cases of misalignment. The dentist might also recommend a palatal expander to create an even bite surface. In some situations, oral surgery will help streamline the process. 

Encourage good behavior, like proper chewing and drinking from a big kid glass instead of a sippy cup, bottle, or straw. Try to prevent your child from chewing their nails and sucking on their thumb, and teach them how to position their tongue inside their mouth without pushing their teeth forward.
