I just brushed my teeth vigorously.
Why did you brush your teeth vigorously?
I was making sure that my mouth was clean.
It's smart to practice good dental hygiene, like brushing your teeth, so that your teeth and gums are clean and healthy. You should continue to brush your teeth several times per day so that you don't have any issues with your oral health.
I don't like to brush my teeth, I don't like the taste of it.
You don't brush your teeth because it tastes good, you should want to brush them so you keep your teeth and gums healthy. Try to brush once a day and floss once a week, it will save you a lot of time and money in the future.
