Severe toothache (especially at night)
Prolonged sensitivity to hot or cold
Pain when biting or chewing
Swelling or pus near the tooth
Tooth darkening

🦷 什么是根管治疗？
根管治疗是一种清除牙齿内部感染（牙髓）并保留患牙的治疗方式，目的是拯救牙齿，避免拔除。
❓什么时候需要做根管治疗？
当牙髓（牙神经）因以下原因受到感染或发炎时可能需要：
龋齿（蛀牙）太深
牙齿断裂或破损
同一颗牙重复接受治疗
外伤（即使牙齿表面无裂痕）
🔍 如果你有以下症状，你可能需要根管治疗：
持续或剧烈的牙痛，尤其是晚上
长时间对冷热敏感
咀嚼或咬合时疼痛
牙龈肿胀、流脓
牙齿变色（变暗）
🛠️ 根管治疗的过程：
拍X光 + 麻醉
医生会先拍摄X光，并为牙齿上麻药。清除感染
在牙齿上打一个小孔，清除感染的牙髓组织，并清洁根管内部。填充根管
用一种特殊材料（如 gutta-percha）填满清理后的根管。封闭 + 做牙冠
封闭开孔处，必要时加上牙冠保护牙齿。
✅ 根管治疗的好处：
保留原生牙齿
缓解疼痛
恢复正常咬合与功能
避免感染扩散
⚠️ 如果不治疗会怎样？
感染可能扩散到牙槽骨
形成脓肿，导致脸部肿胀
最终可能需要拔牙
