When your ClearCorrect aligners are made, they’ll be carefully designed so that they fit perfectly on your teeth. That way, they won’t cause unnecessary irritation to your gums or the inside of your mouth. You might experience some discomfort when wearing a new set of aligners for the first time, but this just means that they’re exerting the necessary pressure on the teeth – in other words, they’re doing exactly what they’re supposed to do. Any minor discomfort or sensitivity usually vanishes after giving your mouth a few days to adjust.
