Invisalign is used to straighten teeth with nearly invisible looking braces. These braces are also removable. They are custom-made set of aligners created for an individual. Aligner trays, as they are called are made of smooth invisible plastic that can be worn over teeth. These braces gradually and gently push the teeth into place. The benefits of invisalign are that they are not like metal brackets that have to be attached and tightened periodically. A new set of aligners is fixed every two weeks until the treatment is complete. An Invisalign treatment orthodontist helps in improving a person's smile by straightening uneven teeth. It treats a variety of teeth disorders like overcrowding, spacing, crossbite, overbite and underbite. It also allows for brushing and flossing normally. With regular braces there are lot of restrictions on the kind of foods that can be eaten, but with invisalign, there are no restrictions on the kinds of food you can take. Also, there is no pain or sores that is associated with metal brackets. With invisalign the risk of tooth deay and gum disease are reduced considerably. Cleaning can be a big challenge when wearing braces. When you begin the treatment, the invisalign dentist will show a digital 3D representation of how your teeth will move during treatment. Invisialign treatment is quite expensive and the duration of the treatment depends on how the teeth align. Doctors may vary when it comes to pricing interaction and treatment. Meet one or more doctors and choose one that fits your needs best.
