It takes 4 years for decay to travel through the enamel layer of permanent teeth. During this phase your dentist can apply topical fluorides and monitor every 6-12 months. In some individuals the progression is faster hence extra care must be taken.
During Root canal therapy we remove he inflamed or infected pulp from inside the tooth and carefully clean and disinfect it. It is then filled and sealed with a material called gutta percha which goes well with the tissues within our body. Afterwards the tooth is restored and a crown or filling is placed. After restoration the tooth continues to function like any other tooth.
It is similar to a routine filling now and can be done in one or two sittings depending on the level of infection.
Crowns (or caps) are dental restorations that are placed over a tooth when a simple filling is insufficient to restore the form and function of the tooth.
Stainless steel crowns are metal caps that repairs a decayed baby molar and prevent it from decaying further. They are made to fit the exact size and shape of the childs molar, and are used to cap teeth with large or deep cavities.
These type of crowns and bridges have a metallic body and prove to be cost effective option for posterior teeth. An acrylic or ceramic facing contributes to the aesthetics. It has a low cost, strength of metal and longevity. Plus less tooth structure is lost. The disadvantage however is that sometimes the metal starts to show due to the wear of acrylic facing in long term use. When the entire crown is coated with a layer of porcelain then it is known as metal ceramic crowns. These also provide the strength of metal and durability and is highly aesthetic as no metal is visible to the outside. The normal life span 6-8 years.
This type as the name suggests have crowns and bridges without the metal core. It is highly recommended for anterior or esthetic restorations of damaged or root canal treated teeth. It provides excellent strength along with guaranteed durability and longevity, especially indicated in the anterior region as a cosmetic treatment.
Advantage is the most natural tooth like appearance while the disadvantage is loss of extra tooth structure and also the cost as compared to the other options available. Life span is proven to be more than full metal and metal-ceramic crowns and bridges.
A bridge or a fixed partial denture is when a missing tooth is replaced by taking the support of the adjacent teeth. The adjacent teeth are trimmed on either side of the space and crowns are joined together to form a bridge. They are available as stainless steel, ceramic facing or metal ceramic crowns and metal free crowns. Regular checkups are required and oral hygiene is very important for the maintainance of the bridge.
