Clear aligners are the most recent form of having straight teeth. They are known as invisible aligners since they are clear and nearly invisible. Aligner trays are custom-made for every patient and are usually made of BPA-free plastic Each tray slowly moves teeth in a steady fashion to achieve the desired position. Aligners are free from wires and brackets.
When you speak of braces, what comes to mind are metal braces which are composed of metal wires and brackets. Today, metal braces are smaller and less visible than previous metal braces This type of braces are the most affordable option.
Ceramic Braces are similar to metal braces with the exception similarly colored like your natural teeth. This type of braces is more expensive than metal braces.
Self-ligating Braces is the latest form of orthodontics. As opposed to conventional braces, self-ligating braces do not use rubbers or elastics to keep wires attached to the brackets. Reduced discomfort, shorter duration of treatment and easier to clean are the advantages of this type. However, they are the most expensive next to clear aligners.
