乳牙蛀成了洞還有必要補(bǔ)上嗎?

If the baby teeth are going to fall out, I don't thinkthat it matters if they become decayed.

如果乳牙是要脫落的，我想蛀了也沒有關(guān)系呀?

You're mistaken about that. Cavities in the babyteeth should be treated for two reasons.

對(duì)于這一點(diǎn)你是錯(cuò)的，乳牙之所以要治療有以下兩個(gè)原因：

First of all, the tooth may become infected if the decay is severe. Infection from a tooth mightbe painful and harmful to a child's general health.

首先，假如蛀得太厲害了，對(duì)于其他牙齒是會(huì)感染的，牙齒感染可能會(huì)痛，對(duì)孩子的全身健康也有害。

The second reason is that premature loss of baby teeth can result in crooked permanentteeth.

第二個(gè)原因是乳牙過早脫落會(huì)使恒牙長(zhǎng)成阻生齒。

For which teeth is the most important?

哪一顆牙齒最重要?

This is particularly important in the permanent first molar (six year molar), and the deciduoussecond molar. If the permanent first molar moves forward because the deciduous second molarhas been lost too soon. the length of the dental arch will be shortened. If that happens, theremay not be space for all the permanent teeth.

恒牙的第一顆磨牙(六歲磨牙)和乳牙的第二顆磨牙最重要，假如恒牙第一顆磨牙因?yàn)槿檠赖牡诙w磨牙過早脫落而向前移動(dòng)，那么齒弓的長(zhǎng)度就要縮短，假如齒弓縮短了，那么對(duì)于所有的恒牙來說，空隙就會(huì)不夠了。

And what do you do if there is not enough space?

假如空隙不夠你就會(huì)怎么做?

A space maintainer is needed if certain baby teeth are lost too soon. A space retainer is neededwhen there isn't enough space. In the way, the dental arch is lengthened and space is made forthe teeth to grow normally.

若有些乳牙過早脫落，那么就需要空隙保持器，當(dāng)空隙不夠的時(shí)候就需要用空隙撐開器，用這種辦法齒弓就可以弄長(zhǎng)，那么就可以為牙齒的正常的發(fā)展騰出空隙。

I never realized that baby teeth are so important.

我過去一直沒有認(rèn)識(shí)到乳牙是這么重要。

Yes. Deciduous teeth are very important. Be sure that all of your children brush their teethwell. Don't give them too many sweet foods. Also, be sure that they have a dental examinationevery six months. Use toothpaste that has a fluoride in it to help strengthen the tooth enameland prevent cavities.

是的，乳牙確實(shí)非常重要，一定要做到使你的孩子們把牙齒刷好，不要給他們吃太多的甜東西，還有，一定讓他們每六個(gè)月到牙醫(yī)那里檢查一次，要用含有氟化物的牙膏，以增強(qiáng)牙齒的琺瑯和防止蛀牙。

I see. We do not use fluoride toothpaste. I didn't know it is so helpful.

明白了，我們沒有用含氟化物的牙膏，我不知道這種牙膏這么有用。

Fluoride that's applied to the teeth by a dentist or dental hygienist is also helpful. Fluoride in achild's drinking water is the third way to strengthen the teeth. It's the most effective way toprevent cavities. Ideally, all three methods of applying fluoride should be used.

由牙醫(yī)或醫(yī)生助理給牙齒涂上氟化物也有效果，第三種增強(qiáng)牙齒的方法是在孩子們喝的水中放入氟化物，這是防止蛀牙的最好辦法，最理想的是三種使用氟化物的辦法都探用。

As for now, Doctor, what is the best thing to do?

就說現(xiàn)在吧，最好的辦法是什么?

There are many things that I have to do before I make a diagnosis and treatment plan for yourson.

在我給你的兒子作出診斷和治療計(jì)劃之前，我要做好些事。
