Teeth - symbolize a fear of you losing sexual attractiveness, fear of aging, lack of self-confidence, feeling inferior, fear of embarrassment, loss of power, or control. It could also suggest you feel you are not being taken seriously, or that what you have to say isn't important to others.

Dreams about your teeth usually reflect your anxiety about your appearance and how others perceive you. Unfortunately, we live in a world where good looks are valued highly, and your teeth play an important role in our 'image'. Teeth are an important feature of our attractiveness and presentation to others. 
Teeth are also used to bite, tear, and chew. In this way, teeth represent power, and our own 'effectiveness'. The loss of teeth in your dream may be from a sense of powerlessness.

You may be experiencing feelings of inferiority and a lack of self-confidence in some situation or relationship in your life.
This dream could be your subconscious telling you that you need to be more assertive and believe in the value of your own opinion.

Rotten or decaying teeth - suggests the need for repair in some area of your life.

Broken or sharp teeth - suggest that you should think before saying something 'sharp' or 'biting'

Blood - It is the life-giving, vital part of our body and it may symbolize our strengths and weaknesses, as well as our physical and mental health. If you are currently experiencing a very difficult time in your life, you may have dreams with bloody and frightening images.

Bleeding - symbol of life or physical, emotional, and/or spiritual energy. It may also symbolize passion, love, guilt...or even anger. Dreaming that you are bleeding, or losing blood may mean that you are feeling emotionally drained.
