牙齒漂白劑的有效成分主要是有氧化功效的化學物質，常見的包括過氧化氫（俗稱雙氧水）和氧化碳醯二胺
The active ingredients of tooth whitening agents are chemicals called oxidizing agents (Hydrogen Peroxide or Carbamide Peroxide).
但要留意不是所有的牙齒色素或色斑都可以用牙齒漂白劑來淡化。牙齒漂白劑的效果主要由色素或色斑的性質及類別決定。
Please note that not all tooth stain or tooth color can be handled by tooth whitening agents. The effect of tooth whitening agents depends on the type and severity of the stain or the tooth color.
如果用選錯了牙齒漂白劑，不但有機會無效，更有可能引致不良後果，例如輕度至中度的牙齒敏感和牙齦受刺激。因此請先和我們邁雋牙科的專業團隊討論，才開始使用牙齒漂白劑。
If you have picked a wrong tooth whitening agent, then it may be ineffective. Moreover, there is a risk of adverse outcomes such as mild to moderate tooth sensitivity and gingival irritation. As a result, please consult our MIAH dental team before you use any tooth whitening agents.
