Then Dr.Richards pointed out a chart.
It helped explain how to prevent cavities.
"Don't have sugary drinks or candy very often. and brush your teeth twice a day" He said.
之后，Richards医生指着海报，为他们更好地解释如何防止蛀牙
他说“不要经常喝糖精饮料或者糖果，一日要刷2次牙。”
As they were leaving, Dr. Richards gave Sarah and Josh each a sticker of a smiling rabiit.
The sticker said "To keep your teeth sparkling clean and bright.
brush early in the morning and last thing in night."
And that's exactly what they did.
当他们准备离开诊所的时候,Richards牙医给了Sarah和Josh每人一个带贴纸的微笑的兔子。
贴纸写着：保持你的牙齿洁白明亮。早晚都要刷牙。
所如医生要求他们做的一样。
"Come on ,get your coats." called Mom.
Sarah and her brother ,Josh tumbled into the room.
" It's time to go to the dentist for your checkups." said Mom.
Sarah和他哥哥Josh跑进房间，妈妈就说“过来，穿上你们的衣服。”
“是时候要去看牙医了做定期检查。”
Sooner they arrived at dentist's office.
Mom told the receptionist their names.
"I want my teeth to stay strong and white like the Rabbit's." Josh told her.
不久，他们就到达牙医的诊所。
妈妈告诉前台他们的名字。
Josh告诉她说“我想的牙齿坚固并且像兔子的牙齿那么白。”
The children played in the waiting room until it was time for their checkups.
Then the dentist took them into the examination room.
"Hi," he said, "My name is Dr.Richards."
孩子们在等候玩耍直到轮到他们检查。
轮到他们，牙医带他们到检查室
牙医说：“你好，我叫Richards医生。”
" Who's going first ?" asked Dr.Richards.
Josh climbed into the chair with Rabbit.
The dentist pressed a button and the chair tipped slowly backward.
“谁先看呢?"Richards医生问。
Josh带着小白兔爬上椅子上。
牙医按了一个制，椅子开始慢慢向后倾。
"Opne wide," said Dr.Richards.
First he checked Josh's gums .
Then he used a small mirror to look for holes called cavities in Josh's teeth.
He didn't find any cavities.
“张开嘴巴”Dr. Richards说。首先检查Josh的下巴。
然后他用小的镜子看看Josh的牙齿里面是否有洞，通常叫蛀牙。
医生没有发现Josh有蛀牙。
"You need to take extra care of the molars at the back of your mouth," he said.
"Right now there is a sticky layer on them. This is called plaque.
it can cause cavity .so you need to brush it away."
“你需要特别保护你嘴后面的臼齿。”医生说.
"在你的牙齿现在有一层粘稠层，叫做牙菌斑。
它可以变成蛀牙，所有你需要刷走它。”
Dr. Richards showed Josh a good way to brush .
"Squeeze a pea-sized blob of toothpast onto your toothbrush.
Then gently brush in little circles," he said.
Richard医生给Josh展示怎样才是正确的刷牙方法。
“挤一滴豌豆大的牙膏在牙刷上，然后轻轻在这个小圈刷。
Josh tried brushing Rabbit's teeth.
"How often do you brush your teeth?" asked Dr. Richards.
"Everyday ,I think," said Josh.
"You should brush twice a day.once in the morning
and once before you go to bed." said Dr. Richards.
Josh尝试刷小兔子的牙齿。
Richards牙医问“你通常多久刷一次牙齿呢？”
Josh说“我想，每日一次。”
Richards医生说“你应该每日刷2次，早晚各一次。”
Then it was Sarah's turn.
" You've lost six of your baby teeth." said Dr. Richards.
" New incisors are growing at the front.
Soon your other baby teeth will get wobbly and fall out.
You'll have 32 new teeth in all."
轮到Sarahle。Richards医生说：“你已经没有6颗乳牙了。有新的门牙在长出来。”
“不用多久，你其他乳牙都会慢慢变松然后会脱落。
到时你会有32颗新牙了。”
Then Dr. Richards found a little cavity in one of Sarah's teeth.
"I'm going to put a filling here," he said.
"A filling is a kind of paste that dries hard,
it will keep the cavity from getting bigger and giving you a toothache."
然后Richard牙医发现在Sarah的牙齿仲有个小小的蛀牙。
牙医说“我准备放一个填充物在这里。填充物是一种粘稠的很干燥硬的物质。
它可以防止蛀牙变大并且可以避免牙痛。”
First Dr.Richards cleaned out the cavity using a drill.
His assistan, Carol ,use a suction tip to suck out any saliva , or spit.
The she gave Sarah a cup of water to rinse out her mouth.
首先Richards医生用钻子清洁干净蛀牙。
助手Carol用一个吸取贴来抽出任何唾液或痰。
然后Carol给一杯水Sarah漱口。
Nex Dr. Richards use an air jet to blow air into cavity.
This dried the cavity so that the filling would stick.
Then he push the filling neatly into the cavity.
"All done," he said.
接下来Richards医生用一个空气喷咀将空气注入蛀牙里面。
这样可以干燥蛀牙，那些填充物就会紧紧粘住。
然后医生将填充物完全放入蛀牙里面。
他说“这样就完成了。”
