I wear invisalign now and I like them alright. There some good things about them, but there's a few things that I dont like about them too. I like that i can take them out anytime I want to, I like that I you cant really see them, also like the fact that my teeth can be cleaned without going around metal. I think they are kind of cool, you get two little red and blue boxes, you wear the red for three weeks and then switch to blue for three weeks. It takes about 6-8 weeks after your first dental appt for the company to make them all. They hurt alittle bit and are uncomfortable like metal braces Im sure, but their moving your teeth so that can be expected. The only thing that bad that I can say about them is that you have to keep them clean all the time. You have to take them out to eat and drink any kind of beverage but water, and if you do not take them out, they can cause staining and discoloration. They should be cleaned out every morning after you wake up, everytime you brush and anytime you have eat or drink something and you cant clean your teeth before you put them back on..so you should clean them out anytime your teeth are not really clean. So if your thinking about using them these are some pros and cons to wearing them.
