How can I minimize teeth pain from crowding?

Flossing!! Braces. The pain you are feeling is not from the crowding. It actually from the gums around the crooked teeth. Keeping the gums healthy through proper brushing and flossing should help minimize the pain. A more long term solution is to get your teeth straighten with braces so that they will be easier to keep clean and improve the health of your gums.
Meds. Dentist. OTC pain meds. See your dentist. He/she may refer you to an othodontist.
