People with crossbite teeth have at least one upper tooth that lies on the inside of the lower teeth. One or more of the upper teeth may be out of position. Other symptoms include an underdeveloped jaw on one side of the face, or scoliosis and headaches.
Sinus pain is another symptom of crossbite teeth. The misaligned bite could restrict drainage in the sinus cavity, leading to chronic inflammation and infection.
The condition could also cause speech impediments, especially if it affects the front teeth and makes it difficult to produce a clear “s” sound.
crossbite is a condition in which the upper teeth do not come down slightly in front of the lower teeth when biting together normally. The term “crossbite” can be used to describe posterior or anterior crossbite, but it is generally used to describe posterior crossbite.
A posterior crossbite can occur on one side (unilateral), both sides (bilateral), or several teeth on either side (segmental). Posterior crossbites can be simple or complex depending on the number of teeth involved. In a unilateral crossbite, only one tooth is inside the dental arch; in a bilateral crossbite, more than one tooth is involved and may involve the entire dental arch.
Crossbite is a malocclusion where the upper teeth are inside the lower teeth, either on one side or both sides of the mouth. The two terms most commonly used to describe this condition are anterior crossbite and posterior crossbite.
Anterior crossbite
This type of crossbite occurs when the upper front teeth are behind the lower front teeth. This can be a single tooth or several teeth. The cause for this type of crossbite is usually due to narrow upper jaw or wide lower jaw. If left untreated, it can lead to gum tissue recession and bone loss in the lower front teeth.
Posterior crossbite
A posterior crossbite occurs when some or all of the upper back teeth bite on the inside surfaces of their opposing lower teeth. Posterior crossbites can happen in one segment or across both sides of the mouth, where all the upper back teeth are too far towards the middle resulting in an overly wide lower jaw. In some cases, it can also be caused by an overly narrow upper jaw.
Malocclusion is a general term that refers to a misalignment of the teeth and jaws. There are three types of malocclusions: skeletal, dental, and functional.
Classification of malocclusion is based on the ABO (American Board of Orthodontics) classification system.
Skeletal malocclusion may be due to one or more of the following problems:
Underdevelopment (hypoplasia) or overgrowth of one or both jaws.
Too short a lower jaw in relation to the upper jaw. This may have genetic causes or arise as a result of premature loss of deciduous teeth, allowing the upper jaw to grow too far forward in relation to the lower jaw.
Too long a lower jaw in relation to the upper jaw. This can be due to genetics or result from retained deciduous teeth in the lower jaw, allowing the lower jaw to grow too far forward in relation to the upper jaw.
A transverse discrepancy, which means that one side of the face is underdeveloped when compared with the other side. This is most often seen on one side of the face as a result of thumb sucking as an infant or mouth breathing during childhood. The tongue normally rests against the palate (roof) of
How Can You Fix a Crossbite?

Misalignment of your teeth, or “malocclusion,” is more common than you may think. Crossbite is a type of malocclusion that occurs when the upper teeth and lower teeth don’t line up properly.
If you have a crossbite and are looking for treatment options, then read on to learn more about the different treatment options available to fix crossbites.*
What causes a crossbite?
The most common cause of a crossbite is an underdeveloped jaw or an overdeveloped jaw. If these conditions aren’t treated during childhood, they can develop into adulthood and cause long-term issues. If a person has a small upper jaw and large lower jaw, it can cause the molars to move out of alignment. This can lead to the upper and lower molars not meeting properly. Other factors that can contribute to misalignment include:
● chewing gum
● tongue thrusting
● thumb sucking
● dental issues such as missing or impacted teeth*
How do you know if you have a crossbite?*
Crossbites are often overlooked because they don’t always cause pain. Some people have mild cases, while others have severe cases.*
Some symptoms of a crossbite include
Orthodontic treatment can be used to correct crossbites. A crossbite is a common dental problem that occurs when the upper jaw and teeth are too narrow or the lower jaw and teeth are too wide. This causes the upper teeth to sit inside of the lower teeth when biting down or closing the mouth.
The most common causes of crossbites include genetics, thumb sucking, tongue thrusting, and pacifier use during the developmental years (under five years old). Rarely, a crossbite can be caused by trauma to the face.
Orthodontic treatment options for correcting a crossbite with braces include using elastics (rubber bands) to expand the upper jaw, widen the palate, and improve breathing function. In severe cases of crossbites in adults, orthognathic surgery may be required to ensure proper alignment.
Crossbite is a dental malocclusion. It’s a condition in which the upper teeth fit inside the lower teeth. When the upper jaw and the lower jaw are misaligned, it causes the crossbite. The crossbite can occur either on one side or both sides of the mouth.
The misalignment of the jaws can be caused by genetics, habits like thumb-sucking, traumatic injury to the mouth, or developmental problems.
Symptoms of crossbite:
If you have crossbite, your symptoms may include:
Difficulty chewing food
Speech impairments
Crowding of teeth
Protruding teeth
Uneven wear on teeth due to incorrect bite
If left untreated, it can cause temporomandibular joint disorder (TMD), gum disease, tooth loss, and bone loss.
The first step is to speak to your dentist to determine the extent of the problem. If your teeth are only mildly crossed, we sometimes do not need to do anything and just monitor the situation very carefully. However, if the crossbite is a serious problem, we may recommend an orthodontic referral.
The orthodontist will most likely recommend braces or clear aligners (Invisalign) to help treat the crossbite. This treatment can take anywhere from 6 months to two years, depending on how bad it is.
I would recommend making an appointment with your dentist so that they can evaluate the situation and decide on a treatment plan for you.
I hope this helps!
The most common method for correcting crossbite is the use of braces. Braces exert light pressure on the teeth, gradually and gently guiding them into their proper position.
The exact way in which your crossbite will be straightened will depend on your particular orthodontic needs. Some methods of correction include:
A palate expander, which is a device that is attached to your upper teeth and works by slowly increasing the width of the upper jaw; this allows the teeth to shift into their correct position.
Braces, which are fixed to the teeth and help move them into the correct alignment.
When you first visit an orthodontist for a consultation, he or she will examine your mouth and take bite impressions in order to determine how severe your crossbite is and what type of treatment would be best for you.
Your age may also determine what type of treatment you receive. Many times children have a growth period in which their jaws can be guided with a palate expander, but once they reach adulthood, their bones are solidified and orthodontic appliances may not work as effectively.
Crossbites are more common in children than in adults, and because the jaw/teeth are more malleable as a child, it’s much easier to correct.
The treatment for a crossbite is different based on the age of the patient. For an adult patient, this will often mean wearing an appliance (retainer) that applies pressure to push one or more teeth into position. For children, it can often be treated by expansion of the upper jaw (orthodontics).
Malocclusion is a condition in which the teeth are improperly aligned when the mouth is closed. There are many types of malocclusion, with crossbite being one of them. It can be a challenging condition to correct because it affects both the upper and lower jaws.
A crossbite is typically caused by an upper jaw that’s too narrow for the lower jaw. This causes one or more of the upper teeth to sit inside the lower teeth when the mouth is closed. The problem can also result from a lower jaw that’s too wide for the upper jaw.
In some cases, there may be a need for orthodontic treatment to correct crossbite. In other cases, surgery may be necessary if braces alone won’t fix the problem. At your initial consultation, your orthodontist will examine your teeth and take X-rays to determine what kind of treatment you need.
Is Crossbite Serious?

Crossbite is a serious condition where the upper teeth do not come down in front of the lower teeth when biting together normally.
When to see a dentist
Crossbite can cause tooth decay and gum disease. Crossbite can also make it difficult to speak or chew. If you have crossbite, your dentist will recommend treatment to help prevent problems with your bite.
Treatment for crossbite
Treatment options include braces or a mouth guard that moves the jaw into its proper position. In some cases, surgery may be needed to correct the problem.
How long does it take to treat crossbite?
The length of treatment depends on how severe your crossbite is and what type of treatment you get. Braces may take as little as 6 months, or as long as 2 years.
Crossbite is a serious dental condition which leads to improper bite alignment, crooked teeth and jaw problems.
Left untreated, crossbite can quickly lead to an array of oral health issues such as tooth decay, gum disease and even tooth loss. In addition, a poor bite alignment may lead to chronic headaches, facial pain and sleep disorders.
Fortunately, crossbite can be easily treated by a licensed orthodontist at any age. The sooner you seek treatment, the faster you receive the benefits associated with a proper bite alignment.
Crossbite is not a serious problem, if it is identified and treated early. If treatment is delayed, then the condition can become more serious. When teeth are misaligned, they may not function properly. The teeth may come together with an improper bite, which causes increased wear and tear to the tooth enamel.
If a person has crossbite for a long time, it can affect the development of their teeth, jaws and facial structure.
Crossbite can prevent teeth from meeting properly when the mouth closes. It can cause the tongue to rub on the roof of the mouth, or push against the cheeks or gums. This can lead to:
tooth pain
speech problems
difficulty chewing food
increased risk of gum disease and tooth decay
Crossbite is a serious problem that can lead to tooth loss, gum disease and jaw problems. Even if you don’t notice any pain or discomfort, you should seek treatment.
The sooner the problem is treated, the less likely it is to cause serious damage. In some cases, orthodontic treatment may be enough to correct crossbite; in more severe cases, surgery may be necessary.
Treatment will depend on how bad the crossbite is and how old you are when it’s diagnosed. Your dentist will be able to tell you what options are available to you and whether they’ll be effective.
Crossbite is a form of malocclusion, which means “bad bite.” It occurs when the upper teeth don’t close properly in front of the lower teeth. In other words, there is a gap between your upper and lower front teeth when you bite down. This can affect just one tooth or many teeth.
Crossbite can be caused by several factors, including a problem with the jawbone, missing or extra teeth, and thumb sucking.
Crossbite should be treated early to prevent further complications to the mouth and teeth. Early crossbite treatment can also shorten the length of treatment time.
If your upper or lower teeth do not come together correctly when you bite, then you have a malocclusion. A crossbite is a type of malocclusion that occurs when the lower jaw bites towards the inside of the upper jaw.
Malocclusions are very common, and most are either genetic or caused by thumb sucking. They do not get better over time, and often lead to more severe dental issues down the road. This is particularly true for crossbites, which can cause jaw pain, tooth decay, and gum disease if left untreated.
Your dentist will likely recommend an orthodontic treatment to correct your bite. However, depending on the severity of your crossbite, they may suggest other treatment options first.
A crossbite is when one or more of the upper teeth bite inside of the lower teeth. This can happen in the front and/or sides of the mouth and can result in a variety of issues.
If left untreated, a crossbite can lead to gum disease and bone loss, which can lead to tooth loss.
The most common solution to a crossbite is braces. In addition to fixing your bite, braces correct crooked or crowded teeth. Braces are worn for at least six months, with adjustments made by your orthodontist every 4-6 weeks.
