Root Canal Treatment

Dent Cure Root Canal Treatment


It is one of the most common treatment undergone in the oral cavity. It relieves the pain and also retains the natural tooth in the oral cavity.

What is a Root canal treatment?

The tooth has two parts – crown and root. The crown constitutes – enamel, dentin, pulp. Root constitutes – cementum, dentin and root canals filled with pulpal tissue. When an infection enters the tooth, it passes through enamel, dentin and reaches the pulp. Inside the pulp, infection reaches the root through root canals and enters the bone below the tooth. The root canal is a removal of all the infection present in the pulp. The sterile, cleaned area in the pulp is sealed and a tooth is covered with a permanent restoration. This treatment has to be performed with the utmost care and bacteria free instruments, then the perfect sealing of the tooth is possible.

When is the root canal treatment done?

There are a number of conditions that affect the teeth and root canal treatment can relieve the pain. The most common being Dental caries.
  • 1. Dental caries
  • 2. Loss of tooth surface i.e, attrition (it is age-associated)
  • 3. Trauma to the tooth (accident)
  • 4. Biting on very hard food that leads to a deep crack in the tooth
  • 5. Abrasion at the lower 1/3 of the tooth
  • 6. Exposure to very high acids on the teeth
  • 7. In cases of bridge placement for missing teeth, in fixed partial denture – the adjacent healthy teeth must undergo root canal treatment before fixing the bridge
  • 8. Teeth that are discolored since the time of eruption – Root canal is generally done before giving a single or multiple crowns.

How will the root canal specialist assess the need for root canal treatment?

The history and symptoms are the best criteria to assess the need. You must give appropriate history and express the type of pain to your dentist. The appearance of the tooth helps in knowing the depth. Apart from these, your dentist will conduct various chair-side tests to arrive in a diagnosis. They include transillumination, cold test, hot test, electric pulp test. The most important one is X-rays. The image of the tooth on the X-ray will help in knowing the depth of tooth damage. Depending on the various factors like the amount of tooth damage, presence or absence of pus, condition of the patient. Your dentist will decide on the need for Root canal treatment. Your root canal specialist will also estimate the needed number of sittings for the Root canal treatment.


CROWN : This is the part of the tooth you can see above the gumline.

ROOT : This part of the tooth sits in the bone below the gum. The root of your tooth is usually twice as long as the crown, the part you see above the gumline.

Why is the Root Canal performed?

The pulp is the living tissue of the tooth with blood supply and nerve supply. Once the dental caries (decay ) involves the pulp, the pulp gets infected causing pain. The aim of the root canal treatment is to remove the infected pulp. This is done by removing the infected pulp with files in the pulp chamber and cleaning and shaping the root canals and sealing the canal with a filling material.


Each tooth has a soft tissue – the pulp which nourishes the tooth. Because of deep decay, injury, or gum disease, the pulp tissue in your tooth has become inflamed or infected. In any other part of your body, if a similar tissue becomes diseased, the body merely throws it off and forms new tissue. However, a tooth is a unique and different. Because the infected soft tissue (pulp) within the tooth is totally encased within hard tissue, it is the role of the dentist to remove the soft tissue located in the root canals, cleanse the area, and finally fill the canals with a special material so that bacteria cannot re-enter the tooth to cause another infection. When the endodontic treatment is complete, the tooth is by no means "dead". It receives quite adequate support from the surrounding tissues and may be expected to last as long as any other natural tooth.

STEP 1: After the tooth is anesthetized, an opening is made through the crown into the pulp chamber.

STEP 2: The length of the root canals is determined.

STEP 3: Unhealthy pulp is removed. Canals are cleaned, enlarged and shaped.

STEP 4: Canals are filled and sealed. A metal post may be added for structural support or to retain restorative materials.

STEP 5: The tooth is sealed with a temporary filling. Usually a crown adds further protection.
