4大因素均有可能与长牙过慢有关

“你家小孩长几颗牙啦?”有了孩子之后,难免经常被街坊邻居、亲戚朋友问到这些问题。一旦发觉自家孩子有发育缓慢的迹象,就显得特别紧张。

宝宝明明已经到了长牙的年龄,为何迟迟不见牙齿冒出呢?父母不禁焦虑起来:“是不是发育有问题?”“要不要补充钙片?”其实,牙齿生长缓慢并非缺乏营养那么简单,以下4大因素均有可能与长牙过慢有关。

先天遗传

幼儿长牙较慢的主要原因来自遗传,包括家庭病史、种族等,甚至连性别也会有所差异。根据多数研究报告来看,女孩的长牙时间会比男孩早一些。

后天环境

除了先天遗传因素之外,后天环境也可能间接造成长牙缓慢。就拿早产儿来说,他的长牙时间就必须先扣除早产时间,这样得出的结论才比较准确。如果 是胎龄30周就出生的早产儿,那么长出第一颗牙的时间就必须延后10周(通常是出生后6~8个月时)。另外,凡是出生体重过轻的婴儿,也很可能出现长牙较 慢的问题。

系统性疾病

唐氏症、脑下垂体分泌异常、外胚层发育不全症候群等,都有可能造成幼儿长牙的速度有所差异,必须通过抽血检查才能确定真正的病因。

外伤与感染

如果孩子的乳牙出现高低不一的情况,则很有可能是牙齿受到过外力撞击,导致与牙齿相连的韧带坏死,而以新生骨头取代(骨沾黏),从外观看来只是 某颗牙齿生长较慢,实际上却会影响到恒牙的萌发。如果幼儿乳牙提早丧失,牙龈表面便会生成结缔组织,一旦恒牙此时还未充分成长,就会受到压迫而导致恒牙出 牙较慢。另外,有时幼儿所服用的药物会让牙龈增厚,牙齿不易冒出,也会让父母产生长牙较慢的误解。

定期检查,放松心态

如果父母不是医生,那么通常都无法正确判断幼儿长牙缓慢的真正原因,因此,从幼儿长出第一颗牙齿到满1岁之前,建议定期前往牙科诊所做检查,请专业医师针对幼儿的具体情况来处理,争取尽快改善长牙状况。

需要提醒大家的是,幼儿的长牙周期都不尽相同,虽说应在约6个月大时长出第一颗牙齿,不过就乳牙而言,出牙的时间差距在半年之内都算正常,而恒牙萌出时间的合理差距甚至可延长至1年。所以,一般无需过度担心,通常只是长牙时间的快慢不同,并不会影响到牙齿的功能。

"Your child grow a few teeth?" After you have children, hard to avoid is often neighbors, relatives and friends asked these questions. Once found signs of slow development of their children, is especially nervous.

Baby yao has arrived in the age of a tooth, why has not the teeth out? Parents can not help but anxious: "development has a www.zshtech.com problem?" "Do you want to calcium?" In fact, the slow growth of the tooth is not always as easy as lack of nutrition, the following four factors are likely associated with tusks too slowly.

genetic

The main cause of infant teething slowly from genetic, including family history, ethnic, and so on, even the gender differences. According to most of the research report, the girl's teeth time will earlier than boys.

The acquired environment

In addition to genetic factors, environment also may indirectly cause teething slowly the day after tomorrow. For premature babies, his www.baigoo.net teeth time must deduct preterm delivery time, so the conclusion is accurate. If it's 30 weeks gestational age was born preterm infants, as long as the first tooth will have to delay the time 10 weeks

(usually 6 ~ 8 months after birth). In addition, who was born underweight babies, is also slower teething problems may come up.

Systemic disease

Down syndrome, abnormal pituitary gland secretion, ectoderm dysgenesis syndrome, etc., are likely to cause children's teeth speed, must through the blood check to determine the real cause.

Trauma and infection

If the child's teeth has the different situation, is a good chance that the teeth by outside force impact, are connected to the teeth in bone necrosis, and bone instead (bone) (vats) with pleurodesis, from appearance looks like just a tooth grew more slowly, but will affect the germination of permanent teeth. If the children's teeth loss of early, gingival surface will be generated in connective tissue, once grow permanent teeth at this time has not yet fully, will be oppressed and cause permanent teeth teething slowly. In addition, all the medicines sometimes children make thickening of gums, teeth are not easy, also can let parents have tusks slower misunderstanding.

Regular inspection, relaxed state of mind

If parents not a doctor, are often difficult to determine the correct baby teeth, the real reason for the slow as a result, from the child grow the first teeth to before one year old, proposed to dental clinic on a regular basis for inspection, please according to the specific condition of young children to deal with a medical professional, strive to improve teeth as soon as possible.

Needing those who remind everybody is, children's tooth cycle is different, although be in about 6 months long out of the first teeth, but in terms of teeth, the tooth gap within half a

3 year of time is normal, and permanent teeth eruption time reasonable gap and can be extended to one year. So, generally without too much worry, usually just a tooth passage of time, will not affect the function of the teeth.
