These are ideal for minor corrective procedures such as misaligned or gapped teeth and work just like traditional metal braces but are far less noticeable. A mould is taken and a customised clear, plastic aligner (similar to a retainer) is made to fit over the teeth and push them into the desired position.
A huge advantage Invisalign braces have over traditional wire braces is the fact that they can be removed for cleaning and eating purposes and other benefits include:
Invisalign braces should be worn every day for up to 22 hours which basically means they should only be removed when brushing the teeth or for eating.
The aligners are replaced every two or three weeks as your teeth move into their proper positions -- and it may be necessary to have the progress checked by the dentist every five to six weeks.
For simple dental issues such as gapped, crowded or crooked teeth, Invisalign is one of the best options currently available and more information can be found in the article at https://yourdentalhealthresource.com/five-fast-facts-regarding-invisalign-treatment/.
