該話題貼近我們的生活，屬於日常生活類話題，主要考查考生對生活類話題的把握和運用。在此我們主要對該話題進行一些拓展，以幫助考生在對話和個人陳述中不拘泥於材料本身，更全面地表達一些觀點。
一. The significance of protecting our teeth
Generally speaking, a charming smile will lighten our life and make others happy. And white teeth are to the smile what water is to fish. A welcoming show of pearly whites makes a great first impression, while a tight-lipped smile or whiff of bad breath does the opposite. In addition, it is a fact that the healthy teeth are the factor with the greatest influence on our confidence. This is why we should pay more attention to our teeth.
二. How to protect our teeth
1. Brush at least two times a day for two minutes
Brushing the teeth is fundamental to protecting the teeth. It is necessary to brush your teeth and tongue with a soft-bristled toothbrush and fluoride toothpaste, which are effective to clean food and bacteria from your mouth. Brushing also washes out particles that eat away at your teeth and cause cavities.
2. Stay away from soda
It’s not just sugar soda, but diet soda, too, that harms teeth. The acid in soda attacks teeth. Once acid eats away at enamel, it goes on to create cavities, leaves stains on the tooth surface, and erodes the inside structure of the tooth. To avoid drinking-related tooth decay, limit soft drinks and take good care of your teeth.
3. Check your teeth regularly
If you haven’t checked your teeth recently, you might consider visiting a dentist. This type of dental medical center offers all kinds of services to their patients, kind of like a Perfect Smile Spa. Your teeth may be simply sensitive to cold weather because they are cracked or have enamel which is either weakened or thin.
4. Try to use floss in your life
Flossing loosens the particles that brushing misses. It also removes plaque, and in so doing prevents the buildup of tartar. While it’s easy to brush plaque away, you need a dentist to remove tartar.
總的來說，保護牙齒的話題不是一個難度很大的話題，大部分考生都能有話可說，關鍵在於我們如何能更好地表達自己的觀點，說一些和別人不一樣的觀點。
