contouring, slenderizing, stripping. This procedure offers fast results and can even be a substitute for braces under certain circumstances. Bonding Bonding is a process in which an enamel-like dental composite material is color matched, applied to a tooth's surface, sculpted into proper tooth contour, hardened and then polished. An examples of a bonded restorations are inlays and onlays, which are used to repair decayed & cracked teeth. Teeth damaged by small to moderate decay, erosion, or small fractures can be repaired with direct composite restorations bonded to the teeth. Aesthetics are especially critical in anterior composite restorations. Bridging Dental bridges are used to replace one or more missing teeth. Teeth on both sides of the space left by the missing teeth are prepared. A bridge is made up of abutments, the teeth that are prepped, and the missing, false teeth, which are called pontics. This procedure is used to replace one or more missing teeth and is cemented in. Bridges can consist of more than three teeth in total and the viability of any bridge is usually determined by applying Ante's Law and assessing where in the mouth the teeth are. Most bridges are fixed, they can not be removed. Fixed bridges cannot be taken out in the same way that partial dentures can. In areas of the mouth that are under less stress, such as the front teeth, a cantilever bridge may be used. Cantilever bridges or Maryland Bridges are used to replace anterior or front missing teeth, are minimally invasive but do have a reputation for failure. Bridges require commitment to serious oral hygiene and carry risk. The average life of bridges is similar to that of crowns which is nearly ten years. Veneers Veneers are ultra-thin, custom-made porcelain laminates that are bonded directly to the teeth. They are an option for closing gaps, enhance the shape, or change the color of teeth that do not respond well to whitening procedures. In the majority of the cases, some level of tooth reduction is necessary for optimal results. To achieve a pleasing smile, dentists fabricate diagnostic mock-ups, which act as a tooth preparation guide before the fabrication of veneers, it allows the dentist to visualize the changes needed to be done on the patient's teeth with respect to size, shape and proportion, its relation with gingival-contour, lip contour and smile line. Mock ups can be a great aid in
