Root Canal Therapy to Save a Bad Tooth

Root canal therapy is a dental procedure performed by dentists when the tooth pulp gets infected. This procedure retards the current infection and also protect the contaminated tooth from further infections. Even though this process is quite complicated and may need multiple visits to the dentist, sometimes it is the only viable option to save the tooth.
Undergo This Procedure to Prevent Further Infections and Pain
Beneath and inside the white enamel of the tooth are the hard dentin layer and the soft tissue called pulp from where the tooth root grows. The latter contains blood vessels, nerve tissues, and connective tissues. When this pulp gets infected, a dentist may have to perform root canal treatment or RCT to remove the infected pulp tissue through a process known as pulpectomy. The nerve of the root canal is also drilled out. Dentists widens the canals with the help of files and debris to remove the infected tissues. This allows greater penetration of the irrigating solution, used in subsequent treatment. The uncontaminated canals are filled with an inert filling and then sealed. Ultimately, the dentists fix a a crown to prevent breakage of the tooth.
Many Advantages Along With Many Limitations
Unless managed effectively, a tooth that has had a bacterial infection will progress with the infection and cause severe pain and stress. A dentist can assess whether an infected tooth needs a simple dental filling, or to proceed with a tooth extraction or an RCT. Studies have shown that most teeth that have had an RCT done last as long as natural teeth, with proper care. A tooth extraction is an irreversible process, which without replacement may cause the surrounding teeth to shift and drift, causing changes in bite and in physical appearance. Salvaging the tooth instead of permanent extraction gives you the benefit of having a functional tooth. However, since blood supply stops and nerves gets removed in this process, the tooth will no longer be vital and will become brittle. RCT is more expensive than an extraction. While the latter gives immediate pain relief without much expense, the former is more complicated and requires multiple visits to the dentist. A tooth, which has had an RCT done, needs a crown, thus adding to the expenses.
An Overview of the Instrumentation for This Process
Efficient and rapid treatment is dependent on availability of well-sterilized endodontic instruments. From patient protection equipment like glasses and rubber dam to the radiographic equipment that gives clear and undistorted views of the teeth and surrounding areas, all equipment are vital. Hand instruments such as the K-type file and the H-file are long needle-shaped instruments used for drilling out nerves from the canal. Pathfinders widen the canal so that the infected pulp could be removed. Irrigation and lubrication is performed with sodium hypochlorite solution. Burs access the canal and shape the cavity for easy procedure. The most commonly used filling material is gutta-percha and sealing materials include eugenol, non-eugenol, and medicated sealers.
