换牙是我们每个人在成长过程中所经历过的，那大家还记得是几岁的时候换的牙吗?或者家乡有哪些换牙习俗?随着世界爱牙日的到来，本篇资讯，亲亲宝贝小编就把各地换牙习俗来了个大总结，并分享给大家。
USA
A child puts the baby tooth under his pillow before going to bed. A tooth fairy comes during the night and takes the tooth with her. The next morning, the child would find money underneath the pillow。
在美国，孩子们在睡觉前把掉了的牙放在枕头下面。夜里“牙仙”来把牙取走，第二天早上，枕头下面会有钱哦~
世界爱牙日：各地换牙习俗各不同
France
Like the American version, the child puts his baby tooth under the pillow when he goes to bed. The fairy takes it while he is asleep, and replaces it with a present instead of money。
在法国，和美国有点像，只是第二天早上枕头下面不是钱而是小礼物。
Mexico
It is the same as the American and the French version, so the child goes to bed with the baby tooth under the pillow. A mouse, not a fairy, takes it during the night. She leaves some money, too。
在墨西哥，和美国、法国有点像，只是来取走牙的是老鼠，当然也会留下钱哦~
Mongolia
In Mongolia, they put the baby tooth in the meat and feed it to the young dog. Because the dog is respected and is considered a guardian angel. When the guardian angel eats it, it is said, that a strong tooth will grow。
在蒙古，人们把乳牙放在小狗的狗食中。因为那里的人把狗看做是守护神。传说如果守护神吃了牙，孩子们就会长出强壮的牙齿。
United Kingdom
Like the American version, the child puts his baby tooth under the pillow. The fairy takes it and replaces it with a coin。
在英国，和美国差不多，不过枕头下面会是一枚硬币。
Spain

Japan
If it is a lower baby tooth, throw it up onto the roof; and if it is an upper tooth, throw it underneath the 'en-no-shita' (the lower portion below the floor of a Japanese house). It is done so that the upper tooth grows healthy downwards, while the lower tooth upwards。
在日本，如果掉的是下牙，就扔到房顶上去;如果是上牙，就放在外廊地板下面。这样是为了让上牙向下长，下牙向上长。
Vietnam
Both the upper and lower teeth are thrown up over the house。
