Restorative dentistry | Management of decayed teeth

When there is slight or moderate tooth decay, i.e. decay is only limited to the enamel or dentine, then decay can be removed and the tooth can be restored with tooth colored filling.

When tooth decay (dental caries) is extensive and has progressed deeper into the tooth, it reaches the pulp chamber affecting the nerves and blood vessels. Such conditions may cause severe toothache, difficulty in biting, chewing and if not intervened, it may even cause swelling and infection around the tooth.

Root Canal Treatment

Root Canal Treatments (RCT) are performed by our endodontic specialists to treat severely decayed teeth. They specialize in quick and painless treatment. The decayed tooth structure is removed. Using specialized intricate instruments, the pulp chamber is cleaned and all infections are removed. Automated instruments and instant digital X-rays may be used to gauge the root length.

The pulp space is disinfected and filled with a permanent, inert material to salvage the tooth and normal functioning.

Post and Core

Sometimes, when a tooth has broken off due to fracture or decay, there may not be enough of natural tooth remaining to place a crown. We specialize in replacing tooth structure even in cases of extensive damage. A post and core is an advanced treatment option. It consists of a “post” that is placed inside the root canal chamber of a tooth. At the tip of the post a “core” is placed. This builds up the top of the tooth in order to hold a crown. The post and core is permanently placed inside the tooth and provides an ideal anchor to which the crown is fixed.


In cases where a tooth has been infected for a very long time & no treatment has been sought, there may develop a severe infection at the root tip. In such cases, an apicoectomy may be done. In this procedure, the gum tissue near the tooth is opened to see the underlying bone and to remove any infected tissue. The infected portion of the root-tip is also removed and the root canal sealed completely to ensure no seepage of infection into the canal.
