Root Canal Treatment – RCT

Root canal treatment (RCT) is the treatment of the canal of a tooth. It is done once a tooth's pulpal vitality is in doubt or it has died. It is done to prevent the further progression of the disease to the peri-apical area, for example, peri-apical granuloma, cyst, or abscess.

Give few examples of the cases where RCT should be done

RCT will be done in the following situations:

After trauma to a tooth:

Suppose a person got a blow to the tooth in a road traffic accident. He/she did not have any problem during or within few days after the accident. But after 3-4 weeks, the tooth concerned started changing its color. From white, it became slight brown and then slowly gray to black.

It is a sign of pulp death that happened due to past trauma.

At the time of accident, the arteries supplying the blood to the tooth got damaged and the tooth stopped getting it nutrients and slowly died. The dead pulp started releasing certain colors that resulted in the color change of that tooth.


Dental Caries:

A person that had carious tooth did not get proper treatment in time and the caries reached the pulp. Once it reached the pulp, it caused the pulp to die. The death of the pulp will cause pain in the advance stage.

In both the above examples, the treatment will be root canal treatment.

But, doing a successful RCT depends on several factors, that only a dentist can decide. Un-necessary RCT is only a wastage of time and money. If in doubt, instead of going for RCT, the best treatment is to remove the tooth and get an artificial replacement.

Periodontitis or Periodontal Infection

Pulp of a tooth may get infected from the periodontal infection. The result will be same as of caries. The treatment involves not only RCT but necessitate the periodontal therapy for a complete success.
