What is the ruling on wearing dental braces to correct spacing, taking into account the saying that this "leads to being cursed" if there is no disfigurement, and does the hadith about "al-mutafallijat for beauty" include wearing braces?

Orthodontic treatment is permissible if it is for treatment and removal of a defect, and it is forbidden if it is merely for improvement and beautification.

The prohibition of "al-tafalluj (filing teeth) for beauty" in the Prophetic Hadeeth applies to orthodontics if it is for changing the creation of Allah.

The prohibition of filing and straightening teeth for beauty is based on it being a change to Allah's creation, a deception, and potentially harmful.

Seeking the wisdom behind Shar’i rulings is legitimate as long as the purpose is to reassure the heart, but submission to the ruling does not depend on knowing the wisdom.
