Are Veneers Prohibited in Islam?
Question

Is it permissible to put Lumineers and veneers (external layers added to protect and beautify the teeth) on the teeth? These are layers that are permanently added to the teeth. Do they have any impact on Wudu?
Praise be to Allah.Are veneers prohibited?
It is permissible to put veneers and the like on the teeth , for the purpose of protection and beautification, or to correct deformities. The basic principle is that things are permissible, and there is no evidence to suggest that this is not allowed. 
However, that is subject to the condition that there is no extravagance, so if there is a high cost to these materials, when there is no need for them, then that should be avoided, because Allah, may He be Exalted, says (interpretation of the meaning):
{And be not excessive. Indeed, He does not like those who commit excess.} [Al-An`am 6:141]
Do veneers affect Wudu?
The presence of this material on the teeth does not affect Wudu, because what is required in Wudu is to rinse out the mouth, which means swishing water in the mouth, which can be done when this material is on the teeth.
