To see a rotten tooth in a dream indicates that the dreamer will support someone who is in a difficult situation around him and he will give his shoulders. It means that the person who sees the dream will support someone by using his financial means and by being a partner in that person's problem and comforting him.
It shows itself in the form of new decisions to be taken, financial relief, seeing new places. This dream, which indicates that there will be important changes in your life soon, is tired for the better. Troubled and restless days will be left behind.
