Millions of dollars are spent every year in fighting tooth decay. Despite better education and a higher standard of living, the number of people needing dental treatment increases every year. A British dentist, Mr. R. V. Tait, has thought about why this is the case, and has made some suggestions about what could be done to improve the situation.
He has pointed out that our 32 teeth evolved in the past to deal with a much tougher diet than we have now. Our ancestors ate tough food, and so they needed many teeth.(33)Our teeth, however, do not have to cope with such a diet, because we eat much softer food. Unless, therefore, we are prepared to cat the diet of our ancestors, we should get rid of some of our teeth. Instead of 32 teeth, it would be better if we had a well-spaced set of 20 to 24.(34)This would force the rest to work harder and make them healthier.
Another advantage would be that with larger space between our teeth, tooth decay could not develop, as it does now. between teeth that are very close together.
Mr. Tait’s theory is original and convincing. It is a remarkable piece of work.(35)because most dentists believe we should keep as many of our teeth as possible. It is unlikely, unfortunately, that they will be persuaded by his idea.
33. Q: Why don’t we need so many teeth as our ancestors?
34. Q: What is the advantage of a well-spaced set of 20 to 24 teeth?
35.Q: What do most dentists think of Mr. Tait’s theory?
