Ask.Dentist 牙牙学医:When do your baby start to get teeth?

When do your baby start to get teeth?

Newborns usually have no visible teeth in their mouth. The baby teeth (milk teeth/primary teeth) gradually erupt through the gums during the first 2 1⁄2 years of life. The four front teeth—two upper and two lower—usually erupt first, beginning as early as six months after birth. Most children have a full set of primary teeth by the time they are 3 years old. 




Baby Teething Problems 


During teething period, some babies may become fussy, sleepless and irritable, lose their appetite or drool more than usual. Diarrhea, rashes and a fever are not normal for a teething baby. If your infant has a fever or diarrhea while teething or continues to be cranky and uncomfortable, call your physician.





What you can do if your baby is teething?


Your baby may have sore or tender gums when their teething. There are many way you can do to help relieve their pain. You could try:
Clean Teething Ring can help relieve your baby teething pain
  1. Rubbing a clean finger or a cold spoon over your baby's sore gums to numb the pain temporarily. 
  2. Giving your baby a clean teething ring. Solid silicone-based or rubber teething rings are recommended over liquid-filled products, which could leak and cannot be sterilised. 
  3. Letting your baby chew on hard non-sweetened rusks, breadsticks or oven-hardened bread. Some parents use frozen bread, such as bagels, for a cool chew. 
  4. Giving your baby fresh and frozen fruit and vegetables, such as cucumber or frozen bananas which can be soothing on the gums.
  5.  Gently rubbing their gums with a clean finger, a small cool spoon, or a moist gauze pad can be soothing. 

*Your dentist or pediatrician may recommend a pacifier or teething ring.

The Food and Drug Administration recommends that parents and caregivers not use benzocaine products for children younger than 2, except under the advice and supervision of a health care professional. Benzocaine is an over-the-counter anesthetic, usually under the product names Anbesol, Hurricaine, Orajel, Baby Orajel and Orabase. Benzocaine has been associated with a rare but serious—and sometimes fatal—condition called methemoglobinemia, a disorder in which the amount of oxygen carried through the blood stream is greatly reduced.



Baby teeth erupted, what's next ?


When your child’s teeth begin to come in, brush them gently with a child's size toothbrush and water. A baby’s front four teeth usually push through the gums at about six months of age, although some children don’t have their first tooth until 12 or 14 months. For children between the ages of 2 and 6, brush their teeth with a pea-sized amount of fluoride toothpaste. Be sure they spit out the toothpaste. (Ask your child's dentist or physician if you are considering using fluoride toothpaste before age 2.)


You should start regular dental check-ups for your child after their first tooth appears, but no later than their first birthday.

宝宝什么时候开始长牙?



新生儿通常在他们的嘴中没有牙齿。在宝宝2岁半之前,宝宝牙(乳牙)会慢慢地从牙龈冒出。通常在宝宝出生的六个月后,牙齿便开始长出来。首先长出来的是四颗门牙两上两下。大多数孩子3岁的时候,他们会拥有全部完整的乳牙。

宝宝出牙期间

有些宝宝在出牙期间,可能会变得挑剔,失眠和烦躁,失去食欲或流比平常多的口水。出牙的婴儿如有腹泻,皮疹和发烧是不正常的。如果你的婴儿有持续发烧或腹泻及不舒服,赶紧打电话给你的医生。








如何减轻出牙疼痛?
你的宝宝可能会有牙龈疼痛症状。有很多方法能让你帮助减轻他们的痛苦。您可以尝试:
  1. 使用干净的手指或冰冷的勺子为宝宝肿痛的牙龈敷上,来暂时麻痹疼痛。
  2. 给宝宝一个干净的出牙环。建议使用固体硅树脂基的或橡胶牙环,不建议使用充满液体的产品因为有可能会导致液体的泄漏而不能进行灭菌。
  3. 让你的宝宝啃硬非甜面包干,面包条或烤箱硬化面包。有些父母会使用冷冻的面包,如面包圈,让宝宝咀嚼。
  4. 给宝宝新鲜和冷冻的水果和蔬菜,如黄瓜或冷藏香蕉可以舒缓牙龈。

*你的牙科医生或儿科医生可能会建议使用一个奶嘴或出牙环。



美国食品和药物管理局建议,家长和照顾者避免使用苯佐卡因(Benzocaine)产品在2岁以下儿童,除非有卫生保健专业人士的意见和监督。苯佐卡因是一种非处方的麻醉剂,含有吃药物的产品如, Hurricaine Anbesol Orajel ,婴儿OrajelOrabase 。苯佐卡因有可能造成致命的情况如高铁血红蛋白血症 (methemoglobinemia),这种情况如果发生,血液流携带的氧气量将大大降低。

宝宝的牙齿出来了,之后呢?

当您的孩子的牙齿开始长出来后,记得使用儿童的牙刷和水轻轻刷牙。前四颗牙齿通常在大约6个月的年龄时长出来,但也有一些孩子直到12个月或14个月才出牙。 26岁之间的儿童,因该刷牙用豌豆大小(pea size)的含氟 (fluoridated)牙膏。刷完牙后,确保他吐出牙膏。 (先咨询你的牙医,如果你正在考虑在2岁前给宝宝使用含氟的牙膏)。
在您宝宝的第一颗牙齿出现后你应该在不迟于他们的第一个生日内开始定期让牙医定期检查。
