Expander is a orthodontic device used to create more space in the mouth to properly align teeth. This device is commonly used in children and adolescents who may not have enough room in their mouths for all of their permanent teeth to come in properly.

Function of Expander

The expander works by applying gentle pressure to the upper jaw, gradually widening the palate. This allows the upper teeth to fit together properly and can also create more room for crowded teeth to align. Expander is typically used before braces are applied to further straighten teeth.

Types of Expanders

There are two main types of expanders - fixed and removable. Fixed expanders are cemented to the teeth and cannot be removed by the patient. Removable expanders can be taken out for eating and cleaning, making them more convenient for some patients. The type of expander used depends on the specific needs of the individual.

Benefits of Expander

Expander can help prevent the need for teeth extractions by creating more space in the mouth. It can also correct issues with the bite and alignment of the teeth, leading to a more aesthetically pleasing smile. Overall, expander can improve the function and appearance of the teeth and jaws.

Orthodontic treatment with an expander is typically well-tolerated by patients and can lead to long-lasting improvements in oral health. It is important to follow the orthodontist's instructions for wearing and caring for the expander to ensure the best results. Regular dental check-ups are also crucial during treatment to monitor progress and make any necessary adjustments.
