Invisalign Teen was created for a teenager whose active lifestyle doesnâ€™t work well with traditional braces. But even more than that, Invisalign had PARENTS in mind! Thatâ€™s right. As a parent myself, I always had two concerns with teenagers wearing Invisalign: 1) They may lose or break them; 2) Theyâ€™re so clear, how do I know they have them in? The answer to question #1 is that Invisalign Teen allows each patient to LOSE or BREAK up to 6 aligners (clear plastic trays that are worn), and there is NO CHARGE to replace them! And the answer to question #2 is that each aligner has a little blue dot that covers the last tooth (molar). This blue dot is actually a â€œwear indicatorâ€ that gradually turns clear over the course of two weeks (which is how long each aligner is worn in the series of aligners). So each week, have your Teen show you their aligner before they go to the next one. If there is still a blue dot, they havenâ€™t worn it!!!
