Can Clear Aligners Fix Overbite/Underbite/Crossbite?

Clear aligners have taken the orthodontic treatment world by storm, presenting a discreet, convenient means to straighten the teeth. Popularly known to correct crooked teeth, more people ask the question: are clear aligners also capable of correcting overbite, underbite, and crossbite? 

If left untreated, these issues not only cause one to chew awkwardly and mispronounce their words but also become serious dental health issues. However, are the aligners effective in these bite corrections? 

Let’s see how they function and if they can solve these bite issues. 

Understanding Different Bite Issues

A well-aligned bite enables the upper and lower teeth to come together in harmony. When alignment goes awry, both functional and cosmetic issues can develop. Here’s a closer examination of three of the most common bite problems:

• Overbite

This is when the front top teeth overlap too much over the bottom teeth. A small overbite is usual, but a large one can cause jaw pain, wear on the enamel, and even gum recession. Overbites are usually due to genetics, habits in childhood such as thumb-sucking, or problems with jaw development.

• Underbite

The reverse of an overbite, an underbite occurs when the lower teeth protrude beyond the upper front teeth. This can cause difficulties in chewing and speaking and can lead to jaw pain. Underbites are often associated with jaw size differences or irregular tooth alignment.

• Crossbite 

A crossbite happens when a few of the upper teeth are positioned inside the lower teeth rather than outside. This alignment may happen with either the front teeth (anterior crossbite) or the back teeth (posterior crossbite). It is usually caused by abnormal jaw growth or the delayed eruption of teeth and may lead to unbalanced wear on teeth as well as gum recession. In such a case, visit an Allen Invisalign dentist.

How Clear Aligners Work?

Clear aligners are individually designed, removable trays that slowly move teeth into more desirable positions. They apply controlled force to move teeth over time, according to a specific digital treatment plan. Patients change to new trays every few weeks, steadily enhancing their alignment. Because they are almost invisible and can be removed for eating and brushing, they provide a more convenient option than conventional braces.

However, can they fix such bite problems as overbite, underbite, and crossbite? The answer is based on the degree of the case.

Can Clear Aligners Fix These Bite Issues?

Overbite Correction

Clear aligners are very effective in correcting mild to moderate overbites. They slowly move the upper and lower teeth to eliminate excessive overlap. In certain instances, other instruments, such as rubber bands or attachments, are employed to improve jaw and tooth movement. Nevertheless, if the overbite is extensive and due to severe jaw malalignment, surgical correction may be required in combination with orthodontic treatment.

Underbite Correction

Mild underbites can often be corrected with clear aligners by shifting the lower teeth back and adjusting the upper teeth forward. However, if a significantly larger lower jaw causes the underbite, aligners alone may not be enough. In such cases, a combination of orthodontic appliances or even jaw surgery may be required to achieve the best results.

Crossbite Correction

Clear aligners can successfully treat some types of crossbites, particularly those affecting only a few teeth. They work by expanding the dental arches and moving misaligned teeth into their correct positions. However, if the crossbite is more complex and involves a narrow upper jaw, additional treatments like palatal expanders may be necessary.

Clear aligners have been successful in correcting a variety of bite issues, including overbite, underbite, and crossbite, with mild and moderate severity. Clear aligners are a pleasant and inconspicuous option to enhance the alignment of your teeth. 

Consult a dental professional to know which course of action will be suitable for you in case you wish to use clear aligners to correct your bites.
