The act of leaving a file in the mouth, also known as dental ligation, is a procedure performed by dentists to correct malocclusions, which are misalignments of the teeth. It is a relatively simple and effective technique that can be used to improve the overall health and appearance of the teeth.
Dental ligation involves placing a small file between two teeth that are out of alignment. The file is then tightened over time, which gradually moves the teeth into their correct positions. This can take several weeks or months, depending on the severity of the malocclusion.
