teeth

Q: Is it permissible to use braces on one's teeth to align the teeth and make it straight?

Q: I very recently had my wisdom teeth removed, and will have another one removed in the next few weeks. After my tooth was surgically removed, it bled continuously for hours (after such procedures, there is continuous bleeding expect for 24-48 hours). Now, I know it is not permissible to swallow blood, however I cannot continuously rinse my mouth, in fact rinsing and spitting to harshly after such surgery can lead to dry sockets which are very painful. I also find it very difficult not to swallow for such a long time (it seems practically impossible for me). What should I do about the blood in this situation? (Note that this is not a small amount of blood). Also, so far I have been praying by having a good supply of tissue in my hand or on the ground next to me and spitting the blood out onto those as I pray. Is this acceptable? Lastly, how do I eat in this situation (when whatever I eat will no doubt mix with the blood in my mouth)? Thank you so much for your help. May Allah bless you.

Q:

1. Should I brush my teeth in order to remove the yellow particles before ghusl of janabah or can I just gargle my mouth? (Just gargling wont remove the yellow particles on the teeth)

2. I know that if one food particle is stuck on the teeth and is less than the size of a chana then no problem but what about if many particles got stuck in many teeth?

Q:

1. Does skin, flesh and teeth become najis when removed from a living human?

2. Must the skin, flesh, and teeth of a living human be buried when removed from the body? For example, when some flesh gets cut off in an injury. Or when a child loses one of his milk teeth.

3. Is it permissible to throw away bloody plasters, tissues, and bandages etc. in the bin?

Q: I did ghusl, but afterwards I found out that there were some food particles in my teeth. Do I need to do ghusl again or just rinse my mouth again?
