You can try listening to this small story about brushing teeth in English before or after you do your own tooth brushing. Of course, I also recommend that...
...you try shadowing this story several times so that you can learn the rhythm and pronunciation, as well as the way the word sounds mix together. Then after brushing your teeth, why not try to repeat parts of this story to test how well you remember it?
I brush my teeth daily. My teeth are not very strong and they get cavities easily. I noticed that many people in other countries have good tooth brushing habits. In fact, I used to hate brushing my teeth when I was younger. It was only when I finally moved to another country that I began to brush my teeth daily.
Now, I brush my teeth in the morning everyday. I also brush after lunch somedays, and I always brush my teeth before going to bed.
What about your routine? When do you brush your teeth? Do you floss your teeth? Think about your routine as you listen to brushing your teeth in English. Be sure to look for words that you don't know and find their meanings, too.
Remember, don't read it every time you listen! Just read it once every four or five times you shadow this story.
