Question

With all kinds of toothbrush and toothpaste ads everywhere, people have come to realize the importance of protecting teeth. "There is no decayed tooth(龋齿) for young children" has become the goal of all parents. Bad teeth may cause a lot of pain or even death. Infections of gums (牙龈) and teeth can release bacteria into the blood system. Those bacteria can increase the chances of a heart attack or stroke and worsen the effects of other disease.

Experts at the National Institutes of Health say good dental care starts at birth. They say breast milk is the best food for the healthy development of teeth. Breast milk can help slow bacterial growth and acid production in the mouth. But dentists say you should clean your baby's gums and early teeth after each feeding. Use a cloth with a little warm water.

When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes specially made for babies. And use them very gently. The use of fluoride (氟化物) to protect teeth is common in many parts of the world. This natural element is often added to drinking water supplies. The fluoride mixes with enamel (牙釉质), the hard surface on teeth, to help prevent holes from forming.

But young children often swallow toothpaste when they brush. The American Academy of Pediatric Dentistry notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully supervised when they brush their teeth. And only a small amount of fluoridated toothpaste, the size of a green pea, should be used.

Parents often wonder about what effect thumb sucking or sucking on a pacifier (橡皮奶嘴) might have on their baby's teeth. Dental experts generally agree that this is fine early in life. The American Academy of Family Physicians says most kids stop sucking their thumbs by the age of four. If it continues, the group advises parents to talk to their child's dentist or doctor. It could interfere with the correct development of permanent teeth.

Dentists say babies should be examined when their first teeth appear --- usually at around six months. Healthy teeth are meant to last a lifetime. If parents pay attention to the above tips, young children’s teeth growing can be good and healthy.
