hi, im 14 and lately ive notice my top 4 teeth have been wiggling, alittle. so ive being brushing and rinsing alot, as well as flossing. im really scared and want to know if this is normal. and wen i floss, it goes up high on my gums, how high is the floss supposed to go? im really nervous. i do have an over bite and do clench my teeth at night. im gettin braces may 2nd if that helps.
