Aligners are clear, removable dental devices used to straighten teeth. They are an alternative to traditional metal braces and are designed to gradually shift teeth into the desired position. Made from a flexible plastic material, aligners are custom-fitted to each individual's mouth, making them comfortable and discreet. Patients typically wear each set of aligners for about two weeks before switching to the next set in the series. Regular check-ups with an orthodontist ensure that the treatment is progressing as planned. Aligners are popular among adults and teens who prefer a less noticeable option for achieving a straighter smile.
