题目内容
19.Are you happy with your teeth?Becca,a 15-year-old girl from the US is not.She decided her teeth needed to be whiter."They weren't that bad,but I wanted to make them all the same colour",she said.In the last five years,teeth whitening has become very popular among young Americans.Now the trend (潮流) has come to China.If you turn on the TV you can see the Hong Kong pop star Karen Mok showing her bright white teeth,saying,"want to be like me?Use white teeth strips (牙贴)!"You may even have decided to buy one.
But wait a minute.Dentists have something to say.They think that kids should not use whitening products until they are 16or even older.
"We don't know what will happen yet,"says Dr.Nasrin Azim,a dentist in Chicago."Studies have not been done on young people.I wouldn't do teeth whitening on anyone under 18."
The problem with whitening lies in the pulp (牙髓),the innermost (最深处的) part of the tooth.It has the tooth's nerve (神经) ending.When we eat very hot or cold things,it's the pulp that hurts.Kids have larger pulps.The larger pulp might make teeth more sensitive (敏感的) to whitening and get hurt.
Another problem is that the gums around the teeth usually change shape (形状) with age.So,if someone whitens his or her teeth during childhood,the darker,natural colour might show later around the gum line.At that time,your teeth will show two colours.And the darker colour is difficult to whiten.
So,wait another few years before you make your teeth whiter.Or if you really want to do it,ask your dentist.They'll give you useful advice.
