I would like a Fatwa about bleaching my teeth I used to have white good teeth and then I had a disease in my teeth which caused them to be so yellow. I am a girl so am I allowed to have them bleached now as they look ugly? Is that Halal or Haram? I will not change what I was born with I am only trying to have what I lost after having the disease.

Praise be to Allah, the Lord of the World; and blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.
You are permitted to receive treatment for your teeth and also to bleach them. This act is not considered as changing the creation of Allah which is prohibited in the Hadith reported on the authority of Ibn Masood that he said: "Allah curses those ladies who practise tattooing and those who get themselves tattooed, and those ladies who remove the hair from their faces and those who make artificial spaces between their teeth in order to look more beautiful whereby they change Allah's creation."
May Allah Bless you and grant you cure.
Allah knows best.
