1 Add 1/2 cup sugar, the ginger, chicken broth, vinegar, soy sauce, sesame oil, and peanut oil; bring to a boil and cook for 3 minutes.  Dissolve 2 teaspoons of cornstarch into the water, and stir into the boiling sauce.
It is made of harmful microscopic bugs that use sugar to attack teeth. With time this creates a little hole in a tooth, and if not repaired with a filling, the cavity continues to grow. If a cavity is not treated it can destroy a good part of the tooth, making it hard to be rapaired with a conventional filling.
This will only push the liquid (and the bacteria that are possibly breeding there [not to scare you or anything ;) ] ) back. BTW, poking a hole in your ear is rarely necessary anymore. It is also dangerous: doing it repeatedly (i.e., if you do it every time you get an ear infection) can result in loss of hearing.
