Cross bite is a condition where more than one tooth is positioned outward or inward in relation to the mouth as compared to the corresponding tooth above or below it. The severity of cross bite can vary from mild to extreme. It is a common condition, which is why you need to know some details about it.
Types of cross bite:
• An anterior cross bite, which is the result of negative over jet or prognathism
• A posterior cross bite, which is the result of a narrow maxillary bone and a narrow upper dental arch.
Causes of cross bite:
• Cross bite is commonly caused by the passing down of family traits
• An unusual eruption of permanent teeth or the late falling out of baby teeth may result in cross bite
• Thumb sucking may also trigger cross bite if the habit is left to continue beyond the normal period. This is because the palate width is constricted and upper jawbone gets deformed
• In some unusual cases, breathing through the mouth can result in a defect in the shape of the maxilla, which in turn may affect teeth arrangement
Indications of cross bite:
• You may experience pain in your jaw or teeth while chewing food
• In severe cases, cross bite may trigger inflammations in your jaw joints, which in turn leads to headaches and swelling
• Untreated cross bite can lead to periodontitis and gingivitis and even loss of tooth
• In rare cases, cross bite may intensify and trigger arthritis of the jaw joints
Cross bite cannot be prevented, but it can be detected at an early stage through periodic dental check-ups. An orthodontist can get teeth straightening done for your teeth so as to correct their misalignment.
• If your problem is breathing through the mouth, then you may need to undergo a tonsillectomy or adenoidectomy before you undergo further treatment for the cross bite
• During the initial stage of the treatment, your upper jaw will be expanded using a maxillary expander
• Your doctor may straighten teeth and treat cross bite with the help of braces
The cross bite can be on one or both sides of the mouth, and if you do not get treatment quickly, then the bone may take upon an abnormal position.
