Should deep root cleaning be done on veneers?

veneers are performed 2 mm, below the gum line , and to have tartar around those veneers its important to remove it ,the only complication  is to have the gums to receed ,then you will have the root of the tooth exposed, and you do not want that,because you will have cavities , so if you are having those veneers to get a deep cleaning due to a gum pocket, then the only thing is not to harm the veneer line adjustment, and also to beware about the receding gum.but yes you can do it.
