Replacement of Milk Teeth

The eruption of permanent teeth has a sequence.

The first permanent tooth is a molar that will erupt at the age of 6. Parents often mistaken this tooth as part of milk teeth and there’s substitute after extraction.

Parents need to give more attention to this permanent molar because it is located behind and most of them do not have the ability to brush their teeth properly and still drink milk and often being bottle fed at night.

 

Frequently Asked Questions:

1. Why there is no replacement after a baby tooth

     has fallen out for such a long time?

 If you do not spot the permanent tooth erupting after 

 several months after the loose tooth falls out which normally

 only take  few weeks. Then it is better to bring your child to

 see the dentist.

   

There are several possible reasons of delay eruption of

permanent tooth which including:

Ø Congenital missing-no permanent tooth bud underneath the milk tooth

Ø Excessive thick and hard gums covering the tooth causing difficult emerge through the gums

Ø Supernumerary ( extra tooth ) in between central incisors

Ø Early loss of milk tooth which changes the balanced position of adjacent teeth. This cause adjacent tooth to loss support and slowly lean towards the gap of missing tooth. Hence, there will be no sufficient space for the tooth to erupt

Therefore, an x-ray examination is important to rule out all possible reasons.

2. Why there is an extra tooth erupting from the outer or

     inner part of the milk tooth?

The root of milk tooth will not be dissolved and loose

if the position of permanent tooth bud is not exactly

below the milk tooth.

Parents should bring their child for tooth extraction and

The permanent tooth will grow to its proper position

after the milk tooth is extracted.

3. What is the solution for the big gap between the  

     newly erupted upper incisors?

This is a transitional stage which called ‘ugly duckling

stage’ where parents often worried about.

The gap will be closed when the lateral incisors and

canines are erupted. Normally, the incisors will be

pushed to the centre and straight up.

 

        

智慧齿小手术知多点！

智智慧牙是怎样拔除的？

1.智慧牙手术是牙医在施以局部麻醉下进行的。局部麻醉会防止任何疼痛的感觉，在手术进行时您只会感觉到一点压力。

 

2.手术时，那覆盖着智慧牙的牙肉会被拔到一边。四周的骨组织会被移去。在把牙拿出前，可能需要把过大的牙切分。最后把伤口缝合。

 

3.手术后，当麻醉剂消失后，您需服用一些止痛药。您也需服抗炎药以防伤口发炎。颊部微肿四、五天是常有的。颊肿也会使你的口不能完全张开。

 

 

 

约2个星期后，您的牙医为您检查伤口，并把缝线去除。

您的责任

手术前：

•  告诉牙医您曾患上或现有的心脏病或其他严重的疾病。
• 告诉牙医您是否对任何药物有过敏的反应。
• 告诉雇主您需要约5天的病假。
• 好好的吃一餐和刷干净您的牙齿。

手术后：

• 伤口少量的流血是正常的，是意料中的。您可以放棉纱在伤口上，然后咬紧20~30分钟，就可以止血。
• 不要用力的漱口或用您的舌头去碰伤口。这样会造成更多的出血。
• 如果您的伤口流血过多，就应该去看您的牙医。

• 可以放冷冰的手帕或冰袋在脸颊旁，这样会减少肿胀。但千万不要放热布在脸颊旁，这样，只会造成更大的肿胀。
• 按时吃药。止痛药有痛时才吃，但消炎药一定要吃完。
• 吃软的食物。例：粥或豆腐。
• 不要做剧烈运动或粗重的工作。
• 不要抽烟和喝酒。
• 手术后第二天可以在饭后用温盐水漱口，或用牙医所给的漱口剂漱口，也同时可以开始刷其他的牙齿。

关于拔牙完以后的牙洞：
1.牙洞长平时间因人而异，一般说法比较多的是2-3个月。 

2.牙洞里的食物残留必须清理出来，食物残渣不但是各种口腔细菌滋长的温床，还会产生口腔异味，增加患各种口腔疾病的机会。用正常的那边牙齿咀嚼吞下食物。
