聽力原文:
How many teeth have you had filled in the past twoyears? If you follow the advice of Dr. Faustick, youmay be able to reduce the number of your visits to adentist. Dr. Faustick conducted a two-year surveyto find out how to prevent or reduce dental decay. 946 students took part in the experiment. 523students cleaned their teeth within ten minutes ofeating. When possible, they used a toothbrush; when this was impossible, they washed theirmouth thoroughly with water. The remaining 423 students merely cleaned their teeth whenthey 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 andmorning group had three times as many decayed teeth as the clean-after-each-meal group. Atthe end of the second year, the latter group had 53 percent fewer decayed teeth than theformer group. Dr. Faustick has cleaned his teeth after every meal for thirteen years and [30]hasnot had a single decayed tooth. He pointed out that [29]sugar is a major agent in dentaldecay, particularly the sugar in sweets, cakes, and soft drinks. [31]Ideally you should keep atoothbrush in your pocket and use it immediately after you have finished eating. When this isimpractical, you can at least make sure that you have a drink of water and let the waterthrough your teeth to force out any particles of food. 7 out of 10 people lose at least half theirteeth by the time they are fifty. Many have a complete set of false teeth by that time. In anycase, neither toothache nor a visit to a dentist is very pleasant. So it is worthwhile making aneffort to keep your own teeth as long as possible. The main preventative agent is simply water.
