Y'know, this *is* the internet.

Anyhow. First link, "Dreammoods.com", says this:

Teeth
To dream that you have rotten or decaying teeth, forewarns that your health and/or business is in jeopardy. You may have uttered some false or foul words and those words are coming back to haunt you.

To dream that you are brushing your teeth, signifies your level of confidence, struggles and aggressiveness. You need to be more look out for yourself.
