Underbites require early treatment

That way, they can be corrected without surgery

Children’s non-surgical underbite

If the lower jaw is slightly more prominent than the upper jaw, and the underbite that people commonly describe starts to appear in your child, early dental treatment is recommended.

If you wait until adulthood, when the skeletal structure has settled, and then try to undergo orthodontic treatment, surgery may become unavoidable.

Because underbites have different causes and types, the treatment method also differs for each case.

If the permanent teeth have not yet erupted, thinking that the underbite will improve naturally as the baby teeth fall out is a mistaken idea.

Permanent teeth grow in where baby teeth fall out, so orthodontic treatment for a children’s non-surgical underbite is definitely necessary.

Dental crossbite

A type of underbite in which the skeletal cause is not strong and it appears only in some teeth, and it can be improved through simple orthodontic treatment

Habitual crossbite

A type of underbite in which a skeletal cause is present and the lower jaw has moved due to bad habits, and it can be improved through orthodontic treatment if the patient is a child

Skeletal crossbite

A type of underbite caused largely by skeletal factors and by imbalance in the growth of the upper and lower jaws, and proper skeletal growth can be guided with an appliance

Dental crossbite

can be corrected with standard orthodontic appliances alone, but habitual crossbite and skeletal crossbite may be treated with an appliance called Frankel.

Frankel blocks the pressure of soft tissues such as the lips and cheeks around the teeth, enabling proper skeletal growth to be guided.

It can be worn from ages 3 to 12, and a treatment plan is established through a growth plate examination.

Why children’s underbite correction is needed

In cases of underbite caused by skeletal factors, even if the patient is a child whose skeleton has not yet finished growing, changing habits, facial massage, or other non-medical methods of improvement are absolutely difficult.

This is not simply a matter of jaw position, but a problem related to the bite, how the teeth fit together, and growth, so it is not something that an ordinary person can resolve on their own.

If the treatment period for this kind of children’s underbite is missed, one may become unable to undergo non-surgical underbite correction after the growth plates close and adulthood begins.

Therefore, if signs of an underbite start to appear, please visit a clinic as soon as possible for diagnosis.

If you visit promptly for a diagnosis and then receive non-surgical underbite correction, it is possible to guide the lower jaw into the proper position, and the before-and-after results for children’s underbite can be favorable.
