TEETH FILLING, VENEERS
We restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma as well as to the replacement of such structure supported by dental implants.
 They are of two broad types--direct and indirect--and are further classified by location and size. A root canal filling, for example, is a restorative technique used to fill the space where the dental pulp normally resides.
Veneers: In dentistry, a veneer is a layer of material placed over a tooth, veneers improve the aesthetics of a smile and/or protect the tooth's surface from damage.
