Ghusal

Validity of ghusal with braces

Q: I have a large gap inbetween my front two teeth. I would like to get braces to close this gap. It is not a major medical problem, and does not affect me, but the dentist has said that because of the way my jaw is positioned, my bottom teeth are pushing my top teeth out and therefore the gap will become bigger with time.

1. Is it permissable for me to get braces?

2. Will my ghusl be valid with braces on?

Ghusal after an operation

Q: Wanted to ask, recently had keyhole surgery and was in haidh but now need to take a bath to become clean. Because of stitches been told not to get that part of the knee wet. Would running across wet palms across that area suffice for ghusal?
