braces vs aligners are both devices that are used to help with crooked teeth. They are both removable appliances that are used to correct the way your teeth look. If you have a baby tooth coming in, you will want to use an aligner. An aligner is a clear plastic device that fits over your teeth, and it will help your teeth come in straight by moving them into the right position. It's important to make sure that you are using your aligner as instructed so that it will work properly.
