What You Need To Know About Crossbite

Children frequently have a crossbite, which does not normally correct itself as they get older. The misalignment might affect either the front teeth, the back teeth, or both. If not treated promptly, the consequences of this malocclusion might be severe. When the upper and lower jaws come together, the way the teeth meet is called occlusion.

What Causes Crossbite?

When the mouth is closed, a crossbite occurs when the upper jaw is excessively thin and sits inside the lower jaw. A crossbite can manifest itself in a variety of ways, all of which can be addressed by an orthodontist. This can make you self-conscious about your smile as well as make eating unpleasant. It can potentially develop into more serious cases like Temporomandibular Joint Disorder (TMD). Jaw pain or discomfort, headaches, earaches, and jaw problems in the muscles that regulate jaw movement can all be caused by TMJ. Taft Hill Orthodontics can assist you in determining the root cause of the problem and preventing TMD as well as other health related repercussions.

Types of Crossbites

There are two types of crossbite in dentistry: anterior and posterior. When the incisors are positioned within the lower jaw, this is known as an anterior crossbite. The back of the jaw is affected by a posterior crossbite. Posterior crossbites are more common, affecting 16 percent of children, compared to 4 to 5 percent of children who have anterior crossbites.

What Issues Do Crossbites Cause?

The common reason why crossbite occurs in children has a relation to genetics. It is an inherited case that the father, mother, or immediate family members may have experienced. Other causes of crossbite include thumb sucking (which is a common childhood habit), prolonged use of pacifier, nail biting, bad chewing habits, or the delayed loss of primary tooth or teeth. Oversized tonsils or adenoids can also contribute to the cause of this condition. Dr. Timothy Hardy can help to identify the cause of your crossbite and advice what can be done about it through taking x-rays during your initial consultation.

You're more prone to experience dental problems, bruxism, health issues, and psychological disorders if your bite is misaligned. Misaligned biting can lead to tooth decay, gum disease, and tension on the jaw muscles, which can lead to chronic jaw disorders, neck, shoulder, and back pain in the long run.

Early diagnosis and correction of these conditions are critical since it allows you to recognize and break the habit, preventing future dental and skeletal problems. Because no treatment can cure this issue, if it is not addressed before it worsens, orthognathic surgery (one of many medical specializations) will need to rectify it.

How To Treat Crossbite Teeth

When the person is a child or in their teens, it is the best time to correct this type of malocclusion since they are still young. Nonetheless, there are still treatments for adults although it takes longer for the restorations to be finished than it does for younger patients. According to the American Dental Association (ADA), the dentist must ensure that there is enough space to shift the teeth in crossbite and that the bite can be opened to make the movement easier. The patient must additionally wear an orthodontic appliance while being treated for the problem.

Maxillary Expander

The orthodontist will place a device on the palate and attach it to the upper teeth. Using a unique key on the device, the maxillary expander gradually extends the upper palate. This device works best in kids whose palates are still developing.

Removable Expander

An adult can utilize expanders to enlarge their upper palate a few changes at a time. Normally, these devices are worn every night until the desired result is attained.

Braces Treatment

Fixing a crossbite with braces is a fixed treatment for all kinds of bite disorders, not just cross bites. Dental braces are used as appliances in this orthodontics process to correct the position of the adult teeth and jaw bone. After braces treatment, a retainer is used to keep the tooth position. You can also use invisalign to treat crossbite. This set of aligners is nearly undetectable, making them an inconspicuous approach to fix your teeth alignment. Clear Braces for a Cross bite are one of the less obvious orthodontic procedures that also provide less visible ways of treating this bite issue.

Surgical Method

After the patient wears a custom-made gadget, the surgeon will purposefully break the jaw bones in various places. Jaw surgery provides for a more extensive expansion than a palate expander can provide. Read about tongue thrust.

Crossbite Vs Underbite

If you close your mouth and your teeth do not line up properly, then you have crossbites. Teeth that are broader and sit on the outside of your bottom teeth form a crossbite.

An underbite is a form of malocclusion in which the lower teeth are spaced apart from the upper teeth. This frequently results in Class 3 malocclusion, which is a jaw misalignment. Read more about overbite.
