2026 香港杜牙根牙齒變黑急救:養和醫生談牙內漂白價錢與過程

2026 香港杜牙根牙齒變黑急救:牙內漂白原理、收費價錢與專家護理攻略

想牙齒變白, 一般人會想到照藍光、 用美白牙貼或藥水等, 但這些方法通常只針對牙齒表面著色的患者。 若果因為嚴重蛀牙、 撞傷或跌斷牙齒而接受 杜牙根(根管治療) 導致牙齒由內而外變黃、 變灰甚至灰黑, 傳統表面美白往往難以奏效。 2026 年, 香港牙科技術已能透過「牙內漂白」技術, 精準解決杜牙根後的色澤問題。

嚴重蛀牙或有需要杜牙根 牙齒可能變灰

一、杜牙根為何會令牙齒變灰黑?

杜牙根即是根管治療,過程中牙醫會取走牙齒內的神經線及血管。部分嚴重蛀牙患者,為了防止牙髓受細菌感染令蛀牙惡化,必須接受此療程以保存牙齒。另外,若牙齒曾受激烈碰撞或損受,亦有需要進行杜牙根。

當牙齒內的神經受損或血管被取出後,牙齒失去營養供應,內部組織的殘餘物或填充材料可能隨著時間分解,導致牙齒顏色逐漸轉變。這種變色是從牙齒內部開始的,因此一般的藍光美白或美白牙膏無法滲透處理。

二、2026 香港牙內漂白收費參考表

牙內漂白通常按每隻牙齒收費,價錢受診所設備、醫生資歷及治療次數影響。

Treatment Program 全科牙醫參考價 (每隻計) 專科牙醫參考價 (每隻計)
牙內漂白 (Internal Bleaching) HK$2,000 – $4,500 HK$5,000 – $8,500
術前全景 X 光檢查 (OPG) HK$500 – $800 HK$1,000+
複合樹脂補牙封口 HK$600 – $1,500 HK$2,000+

三、牙內漂白原理:從內部重拾美白

牙內漂白與一般美白最大的不同在於其介入路徑。牙醫會在牙齒背後開一個小孔(或利用原本杜牙根時的切割孔),將含有雙氧成分的專用漂白劑注入牙齒內部的髓腔,隨後封上洞孔。

治療流程與預期效果:

  • 初期評估:確認杜牙根填充完好,無漏裂情況。

  • 注入藥劑:藥劑會留在牙齒內 7 至 10 天

  • 回診監控:患者覆診讓牙醫檢視顏色轉變。

  • 效果顯著:部分個案在接受治療後不足三日,灰色即顯著消失,顏色變得與鄰牙相若。

四、牙醫專業建議:安全性與禁忌

養和醫院牙科部專家姚嘉琦醫生指出,牙內漂白治療時間短,且不需要切割已經受傷的牙齒,能有效減少痛楚並保留更多健康牙體組織。然而,必須注意以下幾點:

  1. 認可牙醫執行:漂白劑含有高度化學雙氧成分,必須由專業牙醫依照安全劑量指引處理。

  2. 避免牙肉傷害:非專業操作可能導致漂白劑滲漏,刺激牙肉或造成牙根吸收。

  3. 合適時機:杜牙根必須徹底完成且穩定後,方可進行牙內漂白。


Part Three: FAQ (Frequently Asked Questions)

  • Q1:牙內漂白後多久可以食嘢?牙齒會痛嗎?

    • A: 治療完成封洞後即可正常進食,但建議首 24 小時避免進食咖哩、咖啡等深色食物。過程通常無痛,但藥劑運作期間部分人會有輕微痠軟感,屬正常反應。

  • Q2:可以用市面美白藥水自己滴入牙齒孔洞嗎?

    • A: 絕對不可以! 牙齒內部的孔洞必須由牙醫專業密封。自行使用市面產品可能導致嚴重感染、牙質損壞甚至牙齒脫落。

  • Q3:漂白效果可以維持幾耐?要換牙刷嗎?

    • A: 效果通常可維持數年,但具體視乎生活習慣。完成治療後建議更換新牙刷,並使用含氟牙膏加強牙釉質修護,防止外源性色素再次沉著。
