Teeth Care
Dentists say that the most important part of tooth care happens at home. Brushing and flossing properly, along with regular dental checkups, can help prevent tooth decay and gum disease.
Giving Plaque the Brush-Off
To prevent cavities, you need to remove plaque, the transparent layer of bacteria that coats the teeth. The best way to do this is by brushing your teeth twice a day and flossing at least once a day. Brushing also act as stimulus to the gums, which helps to keep them healthy and prevent gum disease.
Toothpastes contain minimal abrasives(磨料), detergents, and foaming agents. Fluoride, the most common active ingredient in toothpaste, is what prevents cavities. So you should always be sure your toothpaste contains fluoride.
About one person in 10 has a tendency to accumulate tartar quickly. Tartar is plaque(硬块) in a hardened form. that is more damaging and difficult to remove. Using antitartar toothpastes and mouthwashes, as well as spending extra time brushing the teeth near the salivary glands(the inside of the lower front teeth and the outside of the upper back teeth),may slow the development of new tartar.
If you have teeth that are sensitive to heat, cold, and pressure, you may want to try a special toothpaste for sensitive teeth. But you'll still need to talk to your dentist promptly about your sensitivity because it may be indicative of a more serious problem, such as a cavity or nerve irritation.
Tips on Proper Brushing
Dentists say that the minimum time you should spend brushing your teeth is 2 minutes twice a day. Here are some tips on how to brush properly:
-Hold your brush at a 45-degree angle against your gumline. Gently brush from where the tooth and gum meet to the chewing surface in short (about half-a-tooth-wide) strokes. Brushing too hard can cause receding gums, tooth sensitivity, and, over time, loose teeth.
-Use the same method to brush all outside and inside surfaces of your teeth.
-Place the brush against the biting surface of the teeth & use a gentle back & forth scrubbing motion. Brush the tongue from back to front to remove odor-producing bacteria.
-To clean the inside surfaces of your top and bottom front teeth and gums, tilt brush vertically behind the front teeth. Make several up & down strokes using the front half of the brush.
-Remember don't share your toothbrush with others. The exchange of body fluids that such sharing would foster places toothbrush sharers at an increased risk for infections, a particularly important consideration for persons with compromised immune systems or infectious diseases.
-Use an egg timer or play a favorite song while brushing your teeth to get used to brushing for a full 2 to 3 minutes. Some electronic toothbrushes have timers that let you know when 2 minutes are up.
Facts on Flossing
Brushing is important but it won't remove the plaque and particles of food between your teeth, under the gumline, or under braces. Sometimes, the bacteria break down the food particles and create volatile sulfur compounds. For this reason you'll need to floss these spaces at least once a day.
With any floss, you should be careful to avoid injuring your gums. Follow these instructions:
-Carefully insert the floss between two teeth, using a back and forth motion.
-Gently bring the floss to the gumline, but don't force it under the gums. Curve the floss around the edge of your tooth in the shape of the letter "C" and slide it up and down the side of each tooth.
-Repeat this process between all your teeth, and remember to floss the back sides of your back teeth.

听力原文： How many teeth have you had filled in the past two years？ If you follow the advice of Dr. Faustick 'you may be able to reduce the number of your visits to a dentist. Dr. Faustick conducted a twoyear survey to find out how to prevent or reduce dental decay. 946 students took part in an experiment. 523 students cleaned their teeth within ten minutes of eating when possible they used a tooth brush, when this was impossible they washed their mouth thoroughly with water. The remaining 423 students merely cleaned their teeth when they went to bed and when they got up in the morning. All the students had their teeth X rayed at the end of the first and second years. At the end of the first year, the night and morning group had three times as many decayed teeth as the dean after each meal group. At the end of the second year the latter group had 53 percent fewer decayed teeth than the former group. Dr. Fausstick has cleaned his teeth after meal for thirteen years and has not had a single decayed tooth. He pointed out that sugar is a major agent in dental decay. Particularly the sugar in sweets, cakes, and soft drinks. Ideally you should keep a tooth brush in your pocket and use it immediately after you have finished eating. When this is impractical you can at least make sure that you have a drink of water and let the water through your teeth to force out any particles of food. 7 of out 10 people loose at least half of their teeth by the time they are fifty. Many have a complete set of false teeth by that time. In any case neither toothache nor a visit to a dentist is very pleas ant. So it is worthwhile making an effort to keep you own teeth as long as possible. The main preventative agent is simply water.

听力原文：M: Hi! Dr. Hyde？
W: So, what seems to ha the problem today？
M: Well, I just came in for a check up and a dental cleaning.
W: Hum. Open up. Let's take a look.
M: Okay. Uh...
W: Hum. Wow! I've never seen one like this before. Let me try this.
M: Uhhh...Ouhhhh [Man screaming in pain].
W: Well, there is a major cavity in one of your wisdom teeth. Hasn't this given you any trouble？
M: Well, the tooth has been bothering me, and it sometimes hurts when I drink something cold. Does it look that bad？
W: Well, we're going to remove the decay, and then we'll either put a filling in, or if the decay is extensive, we can't repair it, we might have to put a crown on your tooth. Or as a last resort, we may have to extract the tooth.
M: Uh, well, that sounds painful!
W: Don't worry. I've done this once before. Nah, just relax.
M: Wait! Aren't you supposed to give me something to dull the pain？
W: Uh, Oh yeah. I almost forget. We can use a local anesthetic to minimize the discomfort you might feel. Or you can just grin and bear it.
M: Nah, nah, nah! Put me under! I can't stand pain, and I'd rather not be aware of what's going on. And, if I need a filling, can I get one that leeks like my other teeth？
W: If we can save the tooth with a filling, I recommend a high-strength silver alloy filling instead of a porcelain one. It'll probably last longer.
M: Okay, well, whatever. Let's get it over with.
W: Okay, pleasant dreams. Drill please.
