Tooth brushing

Some tips:

1. You're supposed to brush your teeth for at least 2 minutes. But if you really don't have the patience, try brushing more on the trouble spots and less on the good teeth. Usually the molars need more of your attention. So repeatedly brush those, in both left-and-right, and back-and-forth directions, inside and outside. Given the same total brushing time, you've made best use of your time.

2. Tongue cleaning is healthful because it clears out germs and eliminates or reduces bad breath, but it's not commonly practiced. Instead of using special tools, why not just use your tooth brushes on the surface of your tongue, or even below it? A few seconds of doing it doesn't take long and brings great benefit.

3. Not really tooth brushing. But I find that the easiest way to remove stains on teeth, such as those left by coffee or tea, is, surprisingly, rubbing with a white rubber eraser! Try it. It works. No need to research for side effects, because there is none. The only problem is that it only works on the teeth in the front, incisors and maybe canines, and not even the inner side of them, and the effect is obviously not as dramatic as the real solution, which may shock your friends and coworkers by suddenly showing ghastly white teeth. Isn't it more pleasing to have just slightly whiter teeth than before? And you only show the front teeth to people you're facing anyway.
