Permanent or fixed retainers are composed of a metal wire that is bonded to your teeth. This wire is often smooth and solid. Sometimes it has a braided texture. It is connected to your teeth and fitted to your bite to prevent them from moving or becoming crooked. Fixed Retainers are easier to wear since you don’t have to take them on and off, making it easier to maintain your teeth in place once your braces are removed. They are tough to harm via regular oral use. They are difficult to destroy, lose, or see by others. Patients seldom have trouble speaking since the wires are so tiny. Cons: They aren’t sufficient on their own. Teeth are still moving! Because fixed retainers can only hold a few front teeth, you will almost certainly need to wear detachable retainers over them. Cleaning around a permanent retainer may be time-consuming and challenging. Fixed retainers are prone to tartar and plaque buildup, necessitating regular flossing.
