有时可成功植入掉落的恒牙,但前提是您必须在去看牙医之前立即遵循以下步骤。
- 处理牙齿时仅触摸顶部或冠部,请勿触摸牙根。
- 检查牙冠和牙根,确定是否有缺失或断裂。
- 清除碎屑时请勿刮擦牙齿。这会损坏牙根表面,降低牙齿存活的可能性。
- 如果您的牙齿上有污垢或异物,请在一碗温热的自来水中短暂地(不超过 10 秒钟)冲洗牙齿,以清除碎屑。不要将其放在自来水下,因为太多的自来水会杀死牙根表面的细胞。而这些细胞有助于重新附着牙齿。
- 试着把您的牙放回牙槽里。如果没有完全到位,请利用纱布或湿纸巾慢慢往下咬,以将它放置到位。保持牙齿固定到位,直到就诊。
- 如果您无法将牙齿放回牙槽,请立即将其放在脸颊和牙龈之间,或放入冷牛奶或您自己的唾液中。或者使用一种非处方产品(如果您能很快获得)保存掉落的牙齿,例如美国牙科协会批准的那些产品。
- 紧急牙齿保健。如果您的牙医诊所没有开门,请去急诊室。
如果孩子的牙齿(乳牙)掉落,则不需要植入。
对于恒牙来说,如果有明显锋利或光亮的表面,则部分牙根可能仍在牙槽中,再植入就不太可能成功。如果在牙齿掉落后的两个小时内没有再植入(越早越好),则成功植入的可能性就会变小。因此,获得紧急牙齿保健至关重要。
