### What is a Crossbite? A crossbite is a dental condition where your teeth don't align properly when your mouth is closed. It can affect a single tooth or groups of teeth, such as your front or back teeth. ### Types of Crossbite 1. **Posterior Crossbite**: This occurs when your upper back teeth sit inside your bottom teeth. 2. **Anterior Crossbite**: This happens when one or some of your upper front teeth sit behind your lower front teeth. ### Causes Crossbites can be caused by dental or skeletal problems, or a combination of both. Factors include habits, tooth growth delays, bone structure issues, upper airway problems, or genetics. ### Symptoms The main symptom is teeth that don’t line up properly. This can vary in appearance depending on the severity and location of the affected teeth. ### Health Impacts If left untreated, a crossbite can lead to jaw problems, facial feature changes, and difficulties in cleaning teeth, which may result in cavities and other issues. ### Treatment Options 1. **Palatal Expander**: An appliance that widens your palate and jaw. 2. **Braces**: These move your teeth into the correct position. 3. **Removable Appliances**: Used mainly for younger children. 4. **Clear Aligners**: Removable braces made of clear plastic. ### Additional Treatments - **Fixed Palatal Crib**: Helps stop thumb or finger sucking. - **Myofunctional Therapy**: Teaches proper chewing, swallowing, and breathing techniques. ### Conclusion Early treatment is crucial, especially in childhood, to prevent further complications. Consult your dentist or orthodontist for the best course of action.
