Bone 牙槽骨
The bone around your teeth is strong and hard, helping to hold each tooth in place.
This bone sits under the gums and is not easy to see without special pictures.
Teeth roots are safely set inside the bone, just like seeds in soil.
The bone gives teeth the support they need for biting and chewing food.
If the bone becomes weak, teeth may feel loose or begin to move.
Brushing and cleaning your mouth every day helps keep this bone healthy and strong.
牙槽骨是包裹牙齿周围的坚硬组织,能把牙齿牢牢固定在口腔中。
这块骨头在牙龈下面,平时用肉眼看不到,需要靠特殊的影像才能看到。
牙齿的牙根就像种子一样,嵌在牙槽骨里。
牙槽骨为牙齿提供足够支撑,让我们可以咬东西、嚼食物。
如果牙槽骨变弱,牙齿就会变松,甚至移位。
每天认真刷牙、保持口腔清洁,有助于让牙槽骨健康结实。
