为什么牙要一颗颗换    Why should dental each change

    不是一次性长的     Is not a one-off

    为什么一颗颗换牙，不是一次性长好呢？因为颌骨到青春期都在不断地发育。出生时，颌骨中已包含乳牙胚与恒牙胚两副发育成熟的牙胚。

    Why is out, right,Not a one-time long good?Because jaws into adolescence is in constant development.At birth,Already included in jaw teeth embryo and two deputy permanent tooth germ development mature tooth germ.

    出生头几个月，颌骨短小脆弱，口腔空间很小。婴儿口腔没有牙齿萌出。6~12月时，乳牙胚顺序发育，乳牙开始萌出。之后，慢慢长出二十颗乳牙。

    Born a few months,Jaw short and weak,Oral cavity space is very small.Baby mouth no teeth eruption.During 6 ~ 12 months,Tooth germ development sequence,Baby teeth begin to appear.after,Slowly grow 20 baby teeth.

    这套按自然选择长出的牙齿，可以一直使用到12周岁左右。期间，颌骨会不断发育。孩子的食物，也有了从母乳、奶粉到米糊、苹果酱等柔软辅食，再到米饭、肉类、水果、蔬菜的改变。

    The grow teeth by natural selection,Can use until about 12 years old.During the period,Jaw is constantly development.The child's food,Have from the breast milk/Milk powder to rice paste/Applesauce etc. Soft side dish,To more rice/meat/fruit/Changes in the vegetables.

    掉了的乳牙为啥没牙根    Why no root teeth away

    乳牙龋齿为啥也要及时治     Deciduous teeth caries why should also be treated in a timely manner

    恒牙牙胚一般在乳牙牙根位置，恒牙牙冠与乳牙牙根接触，乳牙牙根会因受到挤压逐渐被吸收。当完全被吸收，没了颌骨内的固定能力，乳牙就会脱落。这便可以解释，小时候掉的牙齿为啥没牙根。

    Heng fang embryo in baby teeth root position,Constant developing crowns contact with a tooth root,Baby teeth root will squeeze is absorbed gradually.When is absorbed completely,No fixed capacity within the jaw,Baby teeth will fall off.This can explain,When I was a child why didn't root out teeth.

    在实际工作中，最让陈瑶担心的，是乳牙龋齿问题。“家长觉得乳牙要换的，蛀了也没大碍。”事实上，乳牙龋齿严重，会影响到牙根波及“接班”的恒牙。

    In the practical work,The most let Chen yao to worry about,Is deciduous teeth caries."Parents think of baby teeth will change,The decay also no big deal."In fact,,Deciduous teeth caries serious,Affects the root"The succession"The permanent teeth.

    换牙会影响到孩子的面形   Right will affect the child's face

    牙签也会影响牙齿     Toothpicks also affects the teeth

    健康的恒牙能承担更大咀嚼力，完善容貌。颌骨会影响面形。换牙期怎样能让孩子脸型好一点？

    Healthy teeth can bear greater masticatory force,Perfect appearance.Jaw will influence surface shape.Right issue how can let children face a bit better?

    陈瑶建议从小锻炼咀嚼能力，“我的小孩一岁多，把苹果泥改成了苹果丁。门牙长出来，孩子一点点自己吃苹果。”循序渐进让孩子多吃玉米、芹菜等耐嚼食物，刺激乳牙，使其按时脱落，避免“双层牙”。

    Chen yao advice from exercise chewing ability,"My baby more than one year old,Put the apple mud changed to apple.The front teeth grow out,Eat an apple a little bit of their child."Step by step let children eat more corn/Celery, etc. Resistant to chewing food,Stimulates the baby teeth,Make it fall off in time,To avoid"Double teeth".

    “孩子双层牙非常常见，多的时候每天有二三十个案例。”陈瑶建议每过3~6月，孩子应检查牙齿。

    "Children double teeth is very common,When there are twenty or thirty cases every day."Chen yao Suggestions every 3 ~ 6 months,Children should check teeth.

    换牙期间，牙齿易留食物残渣。若刷牙不彻底，没有养成良好的口腔习惯，十分容易产生龋齿。“食物残留在牙缝里，可以刷牙或是使用牙线来处理。”陈瑶强调，使用牙签会对孩子的牙齿造成影响，“网上有牙线使用视频，正确使用，它能顺着牙形将食物带出。” 裘晟佳
