Aligners (clear aligners) are custom-made, transparent plastic trays that fit over teeth, acting as a discreet, removable alternative to traditional braces to gradually straighten teeth for issues like crowding, gaps, overbites, and underbites, requiring removal for eating and cleaning but offering convenience and improved hygiene. They work by applying gentle, consistent pressure, moving teeth incrementally, with patients typically wearing each aligner for about a week, 20-22 hours a day, to achieve desired results. best aligner treatment in santhosapuram best aligner dentist in madambakkam best aligner treatment in medavakkam best orthodontist in selaiyur best orthodontist in rajakilpakkam
