Should a gold tooth be removed from the deceased?
Question

                If a person dies and he has a gold tooth, should it be left or removed? If removing this tooth will result in damage to the remaining teeth, what is the ruling?.
Praise be to Allah.Firstly: It should be 
    noted that it is not permissible to have a gold tooth unless there is a need 
    for that. It is not permissible for anyone to have a gold tooth made for 
    adornment except for women; if it is their custom to adorn themselves by 
    covering their teeth with gold then there is nothing wrong with that. But in 
    the case of men that is not permissible, unless there is a need for that.

     Secondly: If a person who has gold teeth dies, then if it is 
    possible to remove the tooth without mutilating him, then it should be 
    removed, because his possessions are to be transferred to his heirs. If it 
    is not possible to remove it without mutilating him, such as causing the 
    rest of his teeth to fall out, then it should be left and buried with him. 
If the heir is an adult 
    of sound mind and he allows that, it should be left alone. Otherwise the 
    scholars have stated that if he thinks that the deceased has disintegrated, 
    the grave may be dug up and the tooth recovered, because leaving it there is 
    a waste of money and the Prophet  (peace and blessings of Allaah be upon 
    him) forbade that.
