Aligners are removable moulds made of clear plastic. They are used if your condition is mild and you have most of your adult teeth which needs to be moved in place.
A set of two aligners (for upper and lower teeth) needs to be worn for two weeks and than they need to be replaced with a new set. This procedure continues until the treatment is complete and your teeth have moved at the right place.
Advantage of aligners is, they are almost transparent and therefore difficult to notice. At the same time they are easier to clean than braces. Disadvantage of aligners is, they may take longer to improve position of your teeth compared to braces.
