Okay, yesterday i went to see my orthodontist to take pictures of my teeth. They needed to take these 2 fork-like things to stretch open my mouth. after, sticking a mirror in my mouth to add to it. i have a small mouth and they had to take pictures of my teeth with the little stick with air coming out,which makes my mouth and lips really dry. they couldnt catch all the areas, so they kept on sticking the mirror and 2 stick things to open my mouth at least 12 times. then this morning at the sides of my lips i have a little cut or a bump. i keep on putting lip balm on but it doesnt seem to work. any advice? Thanks!
