Invisalign is a system which uses clear plastic aligners to accomplish teeth straightening
, as opposed to using metal braces for the purpose. Many people dislike wearing metal braces because they face teasing from friends, and because they are quite restrictive. Invisalign does not make use of rubber bands or metal wires, and the aligners can be taken out for meals and other occasions. However, they should be left in place for most of the day - even during sleep - so they can accomplish their task in a prompt fashion.
The best thing about Invisalign aligners is that they are virtually invisible to the naked eye, so no one will really notice you're wearing them. If you're conscientious about leaving them in place, they will accomplish whatever teeth straightening is required in half the time that metal braces would. The process works by having you wear several sets of aligners in succession, with each set moving your teeth in the desired direction a little bit at a time. The end result will be that your teeth have achieved their optimal positioning, and you will not have had to undergo all the discomfort which might have attended a similar process using metal braces.
