Crossbite
The Crossbite is when the upper teeth close inside the lower teeth, which can cause dental wear, asymmetries, and chewing problems.
What is Crossbite?
The Crossbite occurs when the upper teeth close inside the lower ones, which can be unilateral or bilateral. This condition can have genetic, functional, or environmental causes, such as anomalies in the development of the jaws, oral breathing, irregular chewing patterns, or early loss of baby teeth. Habits like thumb sucking or prolonged use of a pacifier are also associated. Early diagnosis is essential to prevent future complications.
Main Causes
The development of Crossbite is generally associated with a combination of factors, among which:
Genetic factors
Abnormalities in the development of the jaws
Breathing oral
Irregular chewing patterns
Prolonged oral habits
Possible Symptoms
The symptoms of crossbite can vary depending on the severity and type. Some of the most common signs include: tooth wear, difficulty in chewing, facial asymmetries, pain or discomfort in the jaw, and temporomandibular joint problems.
To Children
In children and adolescents, the existence of a crossbite can impair the normal development of the facial bones, and it is common in cases of unilateral crossbite to even have facial asymmetry. It can also cause changes in phonation (pronunciation of words), chewing, and even breathing.
In Adults
In addition to the aesthetic impact, which can affect the patient's self-esteem, a crossbite is often associated with TMJ disorders (temporomandibular joint disorders). Among the most common symptoms are head and jaw pain, clicks, limited opening and closing of the mouth, and ringing in the ears. Incorrect contact between the teeth can also lead to dental wear, fractures, and gum recession, increasing the risk of functional and structural problems in the long term.
If symptoms persist, worsen, or if you notice visible changes in your teeth, it is important to have a dental assessment.
When discussing the treatment of a crossbite, the approach varies substantially depending on the stage of life in which the diagnosis is made and the treatment planned.
