my girl once fell down and both upper 門牙were indented inwards. They then move back to original position. I took her to check whether the permanent teeth were affected by taking x ray.
乳齒有牙腳, 乳齒牙腳only disappear when the permanent teeth is ready and 乳齒 become loose. So the x ray can check whether the 乳齒牙腳 damage the permanent teeth surface, though not 100% sure. My girl permanent teeth surface may be slightly affected thought the chance is not big. But I don't think it matters a lot. One can easily make the tooth pretty again by dentist. 以前D人D牙食藥食到啡色都可以貼瓷片,D明星個個都整哂排牙。
