Some of our 32 adult teeth are more vulnerable to decay and damage than others. Here, London dentist Dr Charles Ferber reveals where the dangers lie.
你知道嗎？在成人的32顆恒牙中，有的牙齒要更容易遭受損傷和腐蝕，想要有一口漂亮又健康的牙齒，除了日常的清潔護理之外，還應對這一類“VIP牙”進行重點保護。
INCISORS
門牙
Incisors are the eight teeth at the front of your mouth — four at the top, four at the bottom.
門牙是分布于口腔下顎前方的八顆牙齒，四顆在上，四顆在下。
PROBLEMS: The central incisors are most vulnerable, but those in the lower jaw are particularly affected by teeth grinding, which 8 per cent of us do unconsciously.
問題：位于中央位置的門牙是非常容易受到腐蝕的，而下顎的門牙則直接則特別容易遭受磨損。
Your lower central incisors are more -yellow because the enamel is thinner, revealing the yellowish tissue (dentine) that gives teeth their strength.
下門牙很容易呈現出黃色，這是因為琺瑯質較薄而露出了黃色的組織，也就是牙本質的“真面目”，而這樣以外便使得下門牙異常的堅硬。
The inside of these incisors is also particularly prone to tartar because there are -salivary glands here. Minerals in saliva combine with plaque to form hardened tartar. A build-up of tartar can cause -irritation that gradually makes the gum and jawbone shrink.
但因為唾液腺位置的緣故，門牙上也非常容易有牙垢的出現。唾液中的礦物質在結合之后，會形成硬化的斑塊牙垢，而當牙垢積累到一定的程度之后，可能會引起牙齦與顎骨的萎縮。
