They bring back your natural looking smile, structure, function and strength to the tooth. Crowns are used to improve tooth appearance, shape and alignment. It can be placed on top of implant to provide tooth like structure and shape. Ceramic or porcelain crowns were used to match the color of natural teeth. Other materials can also used includes metal alloys, gold, ceramic and acrylic. These mentioned alloys are stronger than porcelain and are recommended for back side teeth.
Initially dentist will remove the decay and shape the tooth, then fitting of temporary crown will be done either with plastic or metal. On the next visit dentist will remove the temporary crown and then adjust and fit the final crown. At last they will cement the crown into place.

Bridges are recommended when you're missing one or more teeth. Gaps left by missing teeth centainly cause the remaining teeth to shift or rotate into the empty spaces, resulting in a bad bite. This imbalance caused by the missing teeth may also lead to gum disease and temporomandibular joint (TMJ) disorders. Bridges are generally used to replace one or more missing teeth. They cover the space where the teeth are missing. Bridges are cemented to the implants or natural teeth surrounding the empty space. These teeth are called abutments they will serve as anchors for the bridge. A replacement tooth is called a pontic, it is attached to the crowns that covers the abutments. With crowns, you have a choice of materials for the bridges. Your dentist will help you to decide what to use, based on the location of the missing tooth or teeth, its function, aesthetic considerations and cost. Porcelain or ceramic bridges can be matched to the color of your natural teeth. The materials used to construct bridges are from gold porcelain, alloys or combination of these two materials.
Crown and bridgesare very reliable solution for major dental problems which are caused through diseases, wear and tear or accidents. Major problems can generally be corrected using these two techniques. Materials used in these two repairs are either porcelain bonded to zirconia or high-grade porcelain. Where accidental damage has caused resulting in lossof teeth or teeth have broken away through excessive wear or as the result of old fillings breaking, crowns and bridges can be used as long-term solution.
