In order to change this state, I think we should first understand the current situation of your teeth: I ask you how is your orthodontics now? Did it work? If you are not sure, go to the doctor to solve the problem; Secondly, if you often have this dream, it's not just your teeth, but also your stomach. People with poor digestive system tend to have such dreams. I suggest you strengthen the spleen and nourish the stomach and improve your physical condition, so that you won't have such a dream before long.
