This exerts an appropriate amount of force on the teeth in correct directions, moving the teeth in the process to realign them.

Orthodontic brackets are usually placed on the front surface of teeth. There are times when the brackets are placed on the inside surfaces of teeth, commonly referred to as lingual braces. Although this hides the orthodontic braces from view, it is an extremely uncomfortable option as the tongue is extremely sensitive and is in constant contact with the brackets and wire, making it prone to trauma.

Conventional metal braces consist of metal brackets and wires that are mainly made from stainless steel, with some containing nickel titanium. Metal braces is the least aesthetic of all, but is gentle on our teeth as it does not tend to grind away edges of tooth upon contact.

Clear braces on the other hand has brackets which are made from ceramic or other plastic tooth coloured material, allowing them to be less visible to others. Metal wire are generally used though white wires and orthodontic rubber bands can be used to provide further cosmetic masking. Ceramic brackets although very aesthetically pleasing, are quite abrasive in nature, which can be a concern if the edges of teeth are in contact with the brackets.
