Is having false teeth fitted regarded as changing the creation of Allaah?
Question

                The dentist can put artificial teeth for us to replace teeth that have been taken out because they were unhealthy and no longer sound.  The dentist says that if the gaps are not filled, it will cause damage to the other teeth. Please note that these false teeth may be fixed or not fixed, i.e., it would be possible to remove them and put them back. Is this halaal or is it haraam and comes under the heading of changing the creation of Allaah?.
Praise be to Allah.
    Fitting false teeth to replace teeth that have been taken out 
    because they were unhealthy or damaged is something permissible and there is 
    nothing wrong with doing it, and we do not know of any scholar who disallows 
    it. It makes no difference whether the teeth are fixed in place in the mouth 
    or not. The patient should do what is best for him in consultation with a 
    specialist in that field. 

    Changing the creation of Allaah means not accepting the 
    creation of Allaah with regard to the length or shape of the teeth or the 
    gaps between them. Hence the one who changes the creation of Allaah in 
    general is cursed, and the one who changes it with regard to his teeth in 
    particular is cursed.  

    Allaah says (interpretation of the meaning): 

    “They (all those who worship others than Allaah) invoke 
    nothing but female deities besides Him (Allaah), and they invoke nothing but 
    Shaytaan (Satan), a persistent rebel!

    118. Allaah cursed him. And he [Shaytaan (Satan)] said: ‘I 
    will take an appointed portion of your slaves.

    119. ‘Verily, I will mislead them, and surely, I will 
    arouse in them false desires; and certainly, I will order them to slit the 
    ears of cattle, and indeed I will order them to change the nature created by 
    Allaah.’ And whoever takes Shaytaan (Satan) as a Wali (protector or helper) 
    instead of Allaah, has surely, suffered a manifest loss”

    [al-Nisa’ 4:117-119]

    It was narrated from ‘Abd-Allaah ibn Mas’ood (may Allaah be 
    pleased with him) that the Prophet  (peace and blessings of Allaah be 
    upon him) said: “May Allaah curse the one who does tattoos and the one who 
    has a tattoo done, the one who plucks eyebrows and the one who has her 
    eyebrows plucked, and those who file teeth for the purpose of 
    beautification, changing the creation of Allaah.” Narrated by Muslim 
    (2125). 

    Al-Nawawi (may Allaah have mercy on him) said: 

    The one who does tattoos is the one who uses a needle and the 
    like on the back of the hand, wrist, temple or other place on a woman’s body 
    where blood flows, then fills that place with kohl etc and it turns blue.  

    “The one who plucks eyebrows” is one who removes hair from 
    the face. 

    “Those who file teeth” refers to women who file the teeth to 
    create a gap between the front teeth and second incisors. This was done by 
    elderly women and those of similar age to make them look younger and to make 
    the teeth look more beautiful, because it is younger girls who have these 
    nice gaps between their teeth. When a woman grows older her teeth become 
    bigger, so they used to file them to make them look nicer and to make people 
    think they were younger. This action is haraam for the one who does it and 
    the one to whom it is done, because of these ahaadeeth, and because it is 
    changing the creation of Allaah, and because it is cheating and deceiving 
    people. 

    “Those who file teeth for the purpose of beautification” – 
    this indicates that what is haraam is that which is done for the purpose of 
    beautification. But if it is needed for medical reasons or to correct a 
    fault in the tooth and so on, then there is nothing wrong with it. 

    Sharh Muslim (14/106, 107). 

    The words of al-Nawawi point to the difference between 
    treating the teeth in order to remove a fault in them and not being pleased 
    with the creation of Allaah and tinkering with it for the purpose of 
    beautification. The former is permissible and the latter is haraam. 

    There is evidence in the Sunnah which shows that it is 
    permissible to wear false teeth if the teeth have fallen out due to old age 
    or sickness, and it is permissible for them to be made of gold if nothing 
    else can be used. 

    It was narrated from ‘Arfajah  ibn As’ad that his nose was 
    cut off at the battle of Kilaab during the Jaahiliyyah, and he wore a nose 
    of silver, but it caused a foul stench, so the Prophet  (peace and 
    blessings of Allaah be upon him) told him to wear a nose made of gold.  

    Narrated by al-Tirmidhi (1770), Abu Dawood (4232) and 
    al-Nasaa’i (5161). Classed as hasan by Shaykh al-Albaani in Irwa’ 
    al-Ghaleel (824). 

    The scholars of the Standing Committee said: 

    But in cases of necessity it is permissible to use gold for 
    teeth, noses and the like, if nothing else can be used instead. End quote. 

    Fataawa Islamiyyah (4/248). 

    Shaykh Muhammad ibn Saalih al-‘Uthaymeen (may Allaah have 
    mercy on him) said:  

    We should note that it is not permissible to have a gold 
    tooth except when there is a need for that. It is not permissible for anyone 
    to have a gold tooth put in for the purpose of adornment, except women for 
    whom is it customary to have gold teeth, in which case there is nothing 
    wrong with it. But for men it is not permissible at all except in cases of 
    necessity. End quote.
