It is a speciality branch of dentistry. Orthodontics not only corrects the position of your teeth if they are crooked or have gaps between them but can also improve your face profile by correcting disproportionate jaw relation ships or modifying and controlling facial growth. Orthodontics can be done for purely aesthetic reasons also as people are becoming more conscious and are looking for a perfect smile.For comprehensive orthodontic treatment, most commonly, metal wires are inserted into orthodontic brackets which can be made from stainless steel or a more aesthetic ceramic material. The wires interact with the brackets to move teeth into the desired positions.Tooth colored ceramic brackets have become very popular as they blend in with the tooth surface. Other methods may include invisalign. Invisalign consists of clear plastic aligners that allow your teeth to realign without others seeing how your teeth are moving especially for those who are conscious of the metal wires being visible in the mouth when the conventional technique is used.
