In the majority of cases, pain, soreness or discomfort goes away on its own, as your mouth and teeth adjust to the feeling of the Invisalign aligners and attachments. You may feel soreness each time you switch to a new set of aligners, but this generally lasts only for a day or two.
Try over-the-counter medication for discomfort or soreness, or try one of the other methods listed above. If pain persists, contact your orthodontist for assistance. It may be necessary to adjust your aligners.
