Root canal treatment starts after a proper diagnosis for an ailing tooth. Diagnosis involves a discussion with the patient regarding signs and symptoms. Dental examination, X-rays, and tests are performed in the mouth. Based on all the information gathered, a determination for root canal therapy is made if the tooth 1) has irreversible inflammation of the pulp (pulpitis) or 2) is dying (necrotic). Irreversible pulpitis is a condition where the tooth's pulp is inflamed from injury and will not recover. A necrotic tooth is a condition where the pulp has lost its vital blood supply and nerve function.
Root canal treatment is functioned under local anesthesia. Earlier to treatment, a rubber dam is set in the mouth to set apart the tooth to be treated and to prevent other parts of the mouth during treatment.
First, an access hole is made in the tooth with the dental drill. For posterior teeth, it is made on the chewing surface while for anterior teeth; it is made into the tongue (lingual) surface of the tooth. This access hole enables the dentist to reach the pulp chamber and root canals. Next, the pulp contents are removed with a small instrument. Afterwards, the inside of the tooth is thoroughly irrigated with an antimicrobial solution that eliminates infection. Small instruments are used to widen and shape the pulp chamber and canals. Widening and shaping the canals allows for thorough and proper cleansing throughout the tooth. Copious irrigation is done intermittently during instrumentation of the canals. Finally, the properly cleaned and shaped chamber and root canals are filled with a sealer and a warm soft rubber material called “gutta percha.” Once a good seal is achieved with the filling materials, the access hole is closed up with a temporary filling or a dental restorative material such as composite resin.
Next, the occlusion (bite) is checked and adjusted to ensure that no heavy biting from the opposite tooth can occur on the treated tooth. For posterior teeth (bicuspids and molars), root canal-treated teeth require dental crowns. Posterior teeth that have lost vitality are more prone to fracture from chewing and need the added protection of a dental crown. In comparison, anterior teeth (incisors and canines) tend not to bear as much force and usually do not require a dental crown. This assessment can be made by the dentist to determine what is best for each individual case. Typically, the crown procedure is done at a separate appointment by the general dentist.


Temporary fillings
A root canal procedure typically requires two dental appointments for it to be complete because the restorative dental crown needs to be made to fit for each single patient. During the first appointment, the root canal is treated and impressions are made for a crown to be constructed to protect the tooth. While the crown is being constructed, a temporary filling is usually used to prevent the tooth.
The temporary filling is not as strong as the permanent crown and is susceptible to fractures. In fact of result, particular care is required until the permanent restoration is in place.
As a common rule, patients should be advised to avoid putting excessive pressure on the affected tooth. They should avoid biting down on very hard or sticky foods, such as hard bread and candy, which may cause the filling to fracture or become dislodged.
Sensitivity, Discomfort and Pain
As the anesthesia used in the root canal treatment procedure wears off and sensation returns, some tenderness or sensitivity in the area may be evident as the tooth heals.
In fact, it is general for patients to experience some sensitivity of the teeth in the days following the treatment procedure. People who were affected by pain or infection before the procedure are most likely to obersve this, even though anyone may be affected. Sensitivity or discomfort can often be relieved with simple analgesic medications such as paracetamol or ibuprofen. For more severe pain, other analgesic medications are also available with a prescription in the most countries.
If pain continues even several days after the procedure, there may be an underlying cause, which should be investigated. In this case, patients should be advised to return to their dentist or endodontist for an examination and to decide on the best treatment options.
