Câu 46-55: Đọc đoạn văn và trả lời câu hỏi:
Reducing your intake of sweet foods is one way to keep your teeth healthy. The least cavity-causing way to eat sweets is to
have them with meals and not between. The number of times you eat sweets rather than the total amount determine how
much harmful acid the bacteria in your saliva produces. But the amount of sweets influences the quanlity of your saliva. Avoid, if
you can, sticky sweets that stay in your mounth a long time. Also try to brush and floss your teeth after eating sugary foods.
Even rinsing your mouth with water is effective. Whenever possible, eat foods with fiber, such as raw carrot sticks, apples, etc...
that scrape off plaque, acting as a toothbrush. Cavities can be greatly reduced if these rules are followed when eating sweets.
