구름방울
하고나면 얼마간 이가 시리긴 한데 금방 좋아진다고 해요 근데 좋아지지않으면 그건 원래 이에 금이가있거나 했던거라고 그렇게 들었어요 일단 병원가서 상담받아보면 더 자세히 알 수 있을 것 같아요 ㅎ

My teeth naturally have a strong yellow tint, so when I was young, I often felt embarrassed because I thought I hadn't brushed my teeth well. That's why I have always been interested in teeth whitening. However, I've heard that teeth whitening procedures can weaken the teeth, so I'm hesitant to undergo the treatment. For those who have tried it, are you satisfied with the results and have you experienced any side effects?
