Bad teeth can be painful — and worse. They can even be deadly. Infections (感染)of the gums (牙龈)and the teeth can cause bacteria (细菌)to go into the blood system. Those bacteria can increase the chance of a heart attack and worsen the effects of other diseases. And adults are not the only ones at risk. For example, in 2007, doctors in the Washington area said a boy died when a tooth infection spread to his brain. They said it might have been prevented had he received the dental care (牙齿 保健)he needed. He was twelve years old.

Experts at the National Institutes of Health say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow the growth of bacteria and acid production in the mouth.

But dentists say a baby's gums and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, only give the child water.

When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently.

The use of fluoride (氟化物)to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel (法琅质), the hard surface on teeth, to help prevent holes from forming.

Millions of girls grow up with the hope of becoming a famous singer. Some even win local talent competitions as children, but only a few such early successes and dreams turn into reality. Jessica Andrews is one of the few whose dreams have come true.

Andrews, first taste of success came at the age of 10. She won a talent competition in her home town of Huntingdon, Tennessee, singing I Will Always Love You, originally sung by Whitney Houston.

With the release of 2001’s, Who I Am, Andrews became a star in her own right. The album was certified (证明)gold for sales of 500,000 copies. Andrews returned in April 2003 with Now,an album that she promised would show a new side of the young artist. "This album has a very different feeling for me," she said.
